  • How Long Is a PhD Thesis?
  • Doing a PhD

It’s no secret that one of the most challenging aspects of a PhD degree is the volume of work that goes into writing your thesis . So this raises the question, exactly how long is a thesis?

Unfortunately, there’s no one size fits all answer to this question. However, from the analysis of over 100 PhD theses, the average thesis length is between 80,000 and 100,000 words. A further analysis of 1000 PhD thesis shows the average number of pages to be 204 . In reality, the actual word count for each PhD thesis will depend on the specific subject and the university it is being hosted by. This is because universities set their own word length requirements, with most found to be opting for around 100,000.

To find out more about how these word limits differ between universities, how the average word count from STEM thesis differ from non-STEM thesis and a more detailed breakdown from the analysis of over 1000 PhDs, carry on reading the below.

Word Count Differences Between Universities

For any PhD student writing a thesis, they will find that their document will be subject to a word limit set by their university. In nearly all cases, the limit only concerns the maximum number of words and doesn’t place any restrictions on the minimum word limit. The reason for this is that the student will be expected to write their thesis with the aim of clearly explaining their research, and so it is up to the student to determine what he deems appropriate.

Saying this, it is well accepted amongst PhD students and supervisors that the absence of a lower limit doesn’t suggest that a thesis can be ‘light’. Your thesis will focus on several years worth of original research and explore new ideas, theories or concepts. Besides this, your thesis will need to cover a wide range of topics such as your literature review, research methodology, results and conclusion. Therefore, your examiners will expect the length of your thesis to be proportional to convey all this information to a sufficient level.

Selecting a handful of universities at random, they state the following thesis word limits on their website:

  • University of Edinburgh: 100,000
  • University of Exeter: 100,000
  • University of Leister: 80,000
  • University of Bath: 80,000
  • University of Warwick: 70,000

The above universities set upper word limits that apply across the board, however, some universities, such as the University of Birmingham and the University of Sheffield, set different word limits for different departments. For example, the University of Sheffield adopts these limits:

  • Arts & Humanities: 75,000
  • Medicine, Dentistry & Health: 75,000
  • Science: 80,000
  • Social Sciences: 75,000-100,000

Although there’s a range of limit, it’s safe to say that the majority fall within the 80,000 to 100,000 bracket.

Word Count Based on Data from past Theses

A poll of 149 postdocs.

In mid-2019, Dr Eva Lantsoght, a published author, academic blogger and Structural Engineering Professor, conducted a poll which asked postgraduate doctoral students to share the length of their final thesis. 149 PostDoc students responded to the survey, with the majority reporting a length falling within the ‘80,000 – 120,000 words’ bracket as seen below.

DiscoverPhDs_How-long-is-a-PhD-Thesis_Poll

Analysis of 1000 PhD Theses

Over a three-year time period, Dr Ian Brailsford, a then Postgraduate Learning Adviser at the University of Auckland, analysed 1000 doctoral thesis submitted to his university’s library. The PhD theses which formed the basis of his analysis were produced between 2008 to 2017 and showed:

  • Average number of pages = 204
  • Median number of pages = 198
  • Average number of chapters = 7.6

We should note that the above metrics only cover the content falling within the main body of the thesis. This includes the introduction, literature review, methods section, results chapter, discussions and conclusions. All other sections, such as the title page, abstract, table of contents, acknowledgements, bibliography and appendices were omitted from the count.

Although it’s impossible to draw the exact word count from the number of pages alone, by using the universities recommended format of 12pt Times New Roman and 1.5 lines spacing, and assuming 10% of the main body are figures and footnotes, this equates to an average main body of 52,000 words.

STEM vs Non-STEM

As part of Dr Ian Brailsford’s analysis, he also compared the length of STEM doctorate theses to non-STEM theses. He found that STEM theses tended to be shorter. In fact, he found STEM theses to have a medium page length of 159 whilst non-STEM theses had a medium of around 223 pages. This is a 40% increase in average length!

Can You Exceed the Word Count?

Whilst most universities will allow you to go over the word count if you need to, it comes with the caveat that you must have a very strong reason for needing to do so. Besides this, your supervisor will also need to support your request. This is to acknowledge that they have reviewed your situation and agree that exceeding the word limit will be absolutely necessary to avoid detriment unnecessary detriment to your work.

This means that whilst it is possible to submit a thesis over 100,000 words or more, it’s unlikely that your research project will need to.

How Does This Compare to a Masters Dissertation?

The average Masters dissertation length is approximately 20,000 words whilst a thesis is 4 to 5 times this length at approximately 80,000 – 100,000.

The key reason for this difference is because of the level of knowledge they convey. A Master’s dissertation focuses on concluding from existing knowledge whilst a PhD thesis focuses on drawing a conclusion from new knowledge. As a result, the thesis is significantly longer as the new knowledge needs to be well documented so it can be verified, disseminated and used to shape future research.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

How long is a Thesis or Dissertation? [the data] PhD, Masters +

Writing a thesis for your undergraduate, master’s, or PhD can be a very daunting task. Especially when you consider how long a thesis can get. However, not all theses are the same length and the expected submission length is dependent on the level of study that you are currently enrolled in and the field in which you are studying.

An undergraduate thesis is likely to be about 20 to 50 pages long. A Master’s thesis is likely to be between 30 and 100 pages in length and a PhD dissertation is likely to be between 50 and 450 pages long.

In the table below I highlight the typical length of an undergraduate, master’s, and PhD.

It is important to note that this is highly dependent on the field of study and the expectations of your university, field, and research group.

If you want to know more about how long a Masters thesis and PhD dissertation is you can check out my other articles:

  • How Long is a Masters Thesis? [Your writing guide]
  • How long is a PhD dissertation? [Data by field]
  • How to write a masters thesis in 2 months [Easy steps to start writing]

These articles go into a lot more detail and specifics of each level of study, including master’s and doctoral degrees.

Let’s take a more detailed look at the length of a thesis or dissertation. We’ll start from the very basics including what a dissertation or thesis really is.

What exactly is a thesis or a dissertation?

A thesis or a dissertation is a research project that is typically required of students in order to gain an advanced degree.

A dissertation is usually much longer and more detailed than a thesis, but they both involve extensive research and provide an in-depth analysis of their given subject.

Many people use the term interchangeably but quite often a Masters level research project results in a thesis. While a PhD research project results in a much longer dissertation.

Thesis work is usually completed over the course of several months and can require multiple drafts and revisions before being accepted. These will be looked over by your supervisor to ensure that you are meeting the expectations and standards of your research field.

PhD Dissertations are typically even more involved, taking years to complete. My PhD took me three years to complete but it is usual for them to take more than five years.

Both a thesis and a dissertation involve researching a particular topic, formulating an argument based on evidence gathered from the research, and presenting the findings in written form for review by peers or faculty members.

My Master’s thesis was reviewed by the chemistry Department whilst my PhD thesis was sent to experts in the field around the world.

Ultimately, these experts provide a commentary on whether or not you have reached the standards required of the University for admittance into the degree and the final decision will be made upon reviewing these comments by your universities graduation committee.

There are several outcomes including:

  • accepted without changes – this is where you must make no changes to your thesis and is accepted as is.
  • accepted with minor changes this is where your thesis will require some minor changes before being admitted to the degree. Usually, it is not sent back to the reviewers after the thesis defence.
  • Major changes – this is where the committee has decided that you need to rework a number of major themes in your thesis and will likely want to see it at a later stage.
  • Rejected – this is where the dissertation or thesis is rejected and the recommendation to downgrade your degree program is made.

What is the typical length of a thesis or dissertation?

The length of a thesis or dissertation varies significantly according to the field of study and institution, especially in social sciences.

Generally, an undergraduate thesis is between 20-50 pages long while a PhD dissertation can range from 90-500 pages in length.

However, longer is not necessarily better as a highly mathematical PhD thesis with proofs may only be 50 pages long.

It also depends on the complexity of the topic being studied and the amount of research required to complete it.

A PhD dissertation should contain as many pages and words as it takes to outline the current state of your field and provide adequate background information, present your results, and provide confidence in your conclusions. A PhD dissertation will also contain figures, graphs, schematics, and other large pictorial items that can easily inflate the page count.

Here is a boxplot summary of many different fields of study and the number of pages of a typical PhD dissertation in the field, including social sciences.  It has been created by Marcus Beck  from all of the dissertations at the University of Minnesota.

how long is a thesis

Typically, the mathematical sciences, economics, and biostatistics theses and dissertations tend to be shorter because they rely on mathematical formulas to provide proof of their results rather than diagrams and long explanations.

On the other end of the scale, English, communication studies, political science, history and anthropology are often the largest theses in terms of pages and word count because of the number of words it takes to provide proof and depth of their results.

At the end of the day, it is important that your thesis gets signed off by your review committee and other experts in the field. Your supervisor will be the main judge of whether or not your dissertation is capable of satisfying the requirements of a master’s or doctoral degree in your field. 

How Many Pages Should a Master or PhD Thesis Have? Length of a thesis?

The length of a master’s thesis can vary greatly depending on the subject and format.

Generally, a masters thesis is expected to be around 100 pages long and should include:

  • a title page,
  • table of contents,
  • introduction,
  • literature review, 
  • main test and body of work, 
  • discussions and citations,
  • conclusion,
  • bibliography
  • and (sometimes) appendix.

Your supervisor should provide you with a specific format for your dissertation or thesis that you are expected to follow.

Depending on your field of study and the word count specified by your supervisor, these guidelines may change. The student must ask their advisor for examples of past student thesis and doctoral dissertations. 

For example, if there is a limited number of words allowed in the thesis then it may not be possible to have 100 pages or more for the thesis.

Additionally, if you are including a lot of technical information such as diagrams or tables in the appendix of your dissertation or thesis, then this could increase the page count as well. For example, my PhD thesis contained a page like the one below.

This page only contains images from atomic force microscopy. Because my PhD was very visual, many pages like this exist.

Ultimately it is important to consult with your supervisor and determine how many pages your master’s thesis or PhD dissertation will be expected to have.

How long does it take to write a graduate thesis? Write your thesis quickly

Writing a graduate thesis can be a daunting task.

It is typically expected to take anywhere from one to three years, depending on the subject and scope of the project.

However, this is not just writing. A typical thesis or dissertation will require you to:

  • formulate a research question
  • do a literature review
  • create research methodology
  • perform original research
  • collect and analyse results
  • write peer-reviewed research papers
  • write a PhD/masters thesis
  • submit thesis and respond to examiners comments.

The actual writing component of a thesis or dissertation can take anywhere from one month to 6 months depending on how focused the PhD student is.

The amount of time it takes to write a thesis or dissertation can vary based on many factors, such as the type of research required, the length of the project, and other commitments that may interfere with progress.

Some students may have difficulty focusing or understanding their topic which can also add to the amount of time it takes to complete the project.

Regardless, writing a thesis is an important part of obtaining a graduate degree and should not be taken lightly.

It requires dedication and determination in order for one to successfully complete a thesis or dissertation within an appropriate timeframe.

In my YouTube video, below, I talk about how to finish your thesis or dissertation quickly:

It is full of a load of secrets including owning your day, managing your supervisor relationship, setting many goals, progress over perfection, and working with your own body clock to maximise productivity.

Wrapping up

This article has been through everything you need to know about the typical length of a dissertation or thesis.

The answer to this question is highly dependent on your field of study and the expectations of your supervisor and university.

Frequently Asked Questions: How Long is a Thesis

How long is a thesis.

A thesis is typically a document submitted in support of an academic degree, presenting the author’s research and findings. The length of a thesis can vary depending on the level of study and specific requirements of the institution. It can range from 60 – 100 pages for a master’s thesis to several hundred pages for a doctoral dissertation.

What is the difference between a thesis and a dissertation?

While the terms thesis and dissertation are often used interchangeably, they can have different meanings depending on the region or academic context. In some countries, a thesis is associated with a bachelor’s or master’s degree, while a dissertation is typically required for a doctoral degree.

Is there a specific word count for a thesis?

While there is no universal word count for a thesis , institutions may provide guidelines on the expected length based on the type of degree and academic discipline. It’s essential to adhere to the specified word count to meet academic standards.

How does the length of a thesis vary across different fields of study?

The length of a thesis can differ based on the field of study and the nature of the research being conducted. For example, a thesis in the social sciences may be shorter compared to one in a scientific or technical field that requires extensive data analysis and documentation.

  • Research, Partnerships and Innovation
  • Postgraduate Research Hub
  • Thesis and Examination: The Code of Practice

Preparing a thesis

Guidance on writing your thesis and the support available.

English language requirements

Theses should normally be written in English. In exceptional circumstances, a student may request permission from their Faculty to present a thesis that is written in another language where there is a clear academic justification for doing so, eg. where the language is directly linked to the research project, or where there is a clear benefit to the impact and dissemination of the research.

Likewise, the oral examination should normally be conducted in English, except in cases where there are pedagogic reasons for it to be held in another language, or where there is a formal agreement in place that requires the viva to be conducted in another language. Permission should be sought from the appropriate faculty for a viva to be conducted in a language other than English.

Guidance on writing the thesis

The main source of advice and guidance for students beginning to write their thesis is the supervisory team. Students should discuss the proposed structure of the thesis with their supervisor at an early stage in their research programme, together with the schedule for its production, and the role of the supervisor in checking drafts. Supervisors should be prepared to advise on such matters as undertaking a literature review, referencing and formatting the thesis, and on what should or should not be included in the thesis, including any supplementary or non-standard material.

Additional support is also available via the English Language Teaching Centre (ELTC), which offers academic writing and thesis writing courses. In addition, the University offers a Thesis Mentoring programme  to help students to manage better the process of writing their thesis.

Students may also find it helpful to consult theses from the same subject discipline that are available in institutional repositories such as White Rose Etheses Online or via the British Library’s EThOS service.

Students who intend to include in their thesis any material owned by another person should consider the copyright implications at an early stage and should not leave this until the final stages of completing the thesis. The correct use of third-party copyright material and the avoidance of unfair means are taken very seriously by the University. Attendance at a copyright training session offered by the Library is strongly recommended.

Students should take care to ensure that the identification of any third-party individuals within their thesis (e.g. participants in the research), is only done with the informed consent of those individuals, and in recognition of any potential risks that this may present to them. This is especially important because an electronic copy of the thesis will normally be made publicly available via the White Rose Etheses Online repository.

Use of copyright material

Guidance on good practices in authorship is set out in the GRIP policy expectations.

Good practices in authorship

Acceptable support in writing the thesis

It is acceptable for a student to receive the following support in writing the thesis from the supervisory team (that is additional to the advice and/or information outlined above), if the supervisory team has considered that this support is necessary:

  • Where the meaning of the text is not clear the student should be asked to re-write the text in question in order to clarify the meaning.
  • If the meaning of the text is unclear, the supervisory team can provide support in correcting grammar and sentence construction to clarify its meaning. If a student requires significant support with written English above what is considered to be correcting grammar and sentence construction, the supervisory team will, at the earliest opportunity, request that the student obtains remedial tuition support from the University’s English Language Teaching Centre.
  • The supervisory team cannot rewrite text that changes the meaning of the text (ghost writing/ghost authorship in a thesis is unacceptable).
  • The supervisory team can provide guidance on the structure, content and expression of writing.
  • The supervisory team can proofread the text.
  • Anyone else who may be employed or engaged to proofread the text is only permitted to change spelling and grammar and must not be able to change the content of the thesis.

The Confirmation Review and the oral examination are the key progression milestones for testing whether a thesis is a student's own work.

Requests for an extension to a student’s time limit for the student to improve their standard of written English in the thesis will not be approved. Students who require additional language support should be signposted to appropriate sources of help at an early stage in their degree to avoid such an occurrence.

Yellow Sticker scheme for disabled students

The University runs a sticker scheme for students who have an impairment that can affect aspects of their written communication. This applies to all students, including PGRs submitting a thesis for examination.

Yellow Sticker scheme

The University does not have any regulatory requirements governing the length of theses, but most faculties have established guidelines:

  • Arts and Humanities: 40,000 words (MPhil); 75,000 words (PhD)
  • Health: 40,000 words (MPhil); 75,000 words (PhD, MD)
  • Science: 40,000 words (MPhil); 80,000 words (PhD)
  • Social Sciences: 40,000 words (MPhil); 75,000-100,000 words (PhD)

The above word counts exclude footnotes, bibliography and appendices. Where there are no guidelines, students should consult the supervisor as to the length of thesis appropriate to the particular topic of research.

1. Different approaches to writing PhD dissertations

Many students are looking for PhD help and high-quality writing services and size of the thesis is one of the most difficult questions to answer. When talking about PhD thesis writing, it is important to emphasise the depth of research and comprehensive analysis of all theories and points. This means that size of a dissertation depends on the specific project requirements. For some dissertations that focus heavily on theoretical considerations, the size is likely to be higher. In this case, there is a lot more past literature to be reviewed and more theories to consider. More empirical works rely on a slightly different approach to thesis writing. In this case, the thesis is expected to be a little bit shorter but more empirical. That is, the key value of the thesis comes from empirical findings rather than theoretical review. Therefore, there are different approaches to writing dissertations thereby affecting length of the thesis. However, the minimum length is about 60,000 words, but the key focus is on the depth of research.

2. Subject area and thesis writing

In addition, the length of a dissertation depends on the subject area. For more research-intensive subject areas, there is more information to include in the dissertation. This naturally leads to higher length of the thesis. For areas with much previous literature attention the word count is likely to be larger because of more massive literature review and more opportunities for research. Some new projects with the lack of the academic focus in the past can be shorter. Thesis writing for a social sciences course implies probably larger project size compared to the thesis for science or medicine. Nevertheless, there is no strict answer to this question on the size of a PhD dissertation. There are different factors that come into play and the subject area is one of them.

3. University rules

Another important factor to consider is the university and its PhD dissertation rules and word limits. PhD thesis writing is similar across universities but there are some notable differences. Some universities allow for more strict word limits such as 75,000-80,000 words. Others set higher word limits of 100,000 words or more. Generally, university or course requirements influence size of a PhD thesis. This means that there is no one answer on the size of the thesis paper. Each university has its own standards for PhD thesis writing, so there are significant variations across universities.

The question on how long the PhD dissertation should be is not new. Moreover, each year there are thousands of students who ask exactly the same question. The simple answer can be – “long enough to properly answer the question”. This means that there is no one size that fits all theses. The length of the paper depends on the subject area and university. In addition, depth of research also affects the thesis writing and length of a PhD thesis. Most of theses range from 70,000 to 100,000 words in size. However, each student should consult with his/her faculty on the project size.

Word limits and requirements of your Degree Committee

Candidates should write as concisely as is possible, with clear and adequate exposition. Each Degree Committee has prescribed the limits of length and stylistic requirements as given below. On submission of the thesis you must include a statement of length confirming that it does not exceed the word limit for your Degree Committee.

These limits and requirements are strictly observed by the Postgraduate Committee and the Degree Committees and, unless approval to exceed the prescribed limit has been obtained beforehand (see: Extending the Word Limit below), a thesis that exceeds the limit may not be examined until its length complies with the prescribed limit.

Extending the Word Limit

Thesis word limits are set by Degree Committees. If you need to increase your word limit, to include appendices where these are normally included in the word limit set by your Degree Committee, or include additional figures or images you will need to apply for permission. If you need to include materials that are integral to the thesis but in a format that cannot be easily included in the body of the thesis (for example, 3D graphics), you need to apply for permission to include additional materials .

Information on how to apply (via self-service account) is available on the ‘ Applying for a change in your student status’  page. If following your viva, you are required to make corrections to your thesis which will mean you need to increase your word-limit, you need to apply for permission in the same way.

Requirements of the Degree Committees

Archaeology and anthropology, architecture and history of art, asian and middle eastern studies, business and management, clinical medicine and clinical veterinary medicine, computer laboratory, earth sciences and geography, scott polar institute, engineering, history and philosophy of science, land economy, mathematics, modern and medieval languages and linguistics, physics and chemistry, politics and international studies, archaeology and social anthropology.

The thesis is not to exceed 80,000 words (approx. 350 pages) for the PhD degree and 60,000 words for the MSc or MLitt degree. These limits include all text, figures, tables and photographs, but exclude the bibliography, cited references and appendices. More detailed specifications should be obtained from the Division concerned. Permission to exceed these limits will be granted only after a special application to the Degree Committee. The application must explain in detail the reasons why an extension is being sought and the nature of the additional material, and must be supported by a reasoned case from the supervisor containing a recommendation that a candidate should be allowed to exceed the word limit by a specified number of words. Such permission will be granted only under exceptional circumstances. If candidates need to apply for permission to exceed the word limit, they should do so in good time before the date on which a candidate proposes to submit the thesis, by application made to the Graduate Committee.

Biological Anthropology:

Students may choose between two alternative thesis formats for their work:

either in the form of a thesis of not more than 80,000 words in length for the PhD degree and 60,000 words for the MSc or MLitt degree. The limits include all text, in-text citations, figures, tables, captions and footnotes but exclude bibliography and appendices; or

in the form of a collection of at least three research articles for the PhD degree and two research articles for the MSc or MLitt degree, formatted as an integrated piece of research, with a table of contents, one or more chapters that outline the scope and provide an in-depth review of the subject of study, a concluding chapter discussing the findings and contribution to the field, and a consolidated bibliography. The articles may be in preparation, submitted for publication or already published, and the combined work should not exceed 80,000 words in length for the PhD degree and 60,000 words for the MSc or MLitt degree. The word limits include all text, in-text citations, figures, tables, captions, and footnotes but exclude bibliography and appendices containing supplementary information associated with the articles. More information on the inclusion of material published, in press or in preparation in a PhD thesis may be found in the Department’s PhD submission guidelines.

Architecture:

The thesis is not to exceed 80,000 words for the PhD and 60,000 words for the MSc or MLitt degree. Footnotes, references and text within tables are to be counted within the word-limit, but captions, appendices and bibliographies are excluded. Appendices should be confined to such items as catalogues, original texts, translations of texts, transcriptions of interview, or tables.

History of Art:

The thesis is not to exceed 80,000 words for the PhD and 60,000 words for the MLitt degree. To include: footnotes, table of contents and list of illustrations, but excluding acknowledgements and the bibliography. Appendices (of no determined word length) may be permitted subject to the approval of the candidate's Supervisor (in consultation with the Degree Committee); for example, where a catalogue of works or the transcription of extensive primary source material is germane to the work. Permission to include such appendices must be requested from the candidate's Supervisor well in advance of the submission of the final thesis. NB: Permission for extensions to the word limit for most other purposes is likely to be refused.

The thesis for the PhD degree is not to exceed 80,000 words exclusive of footnotes, appendices and bibliography but subject to an overall word limit of 100,000 words exclusive of bibliography. Students may apply to include appendices that are exclusive of the word count. In order to be eligible, appendices must be of a none-discursive nature such as lists of linguistic examples, transcriptions of excerpts from works, interviews, inscriptions, archival documents, and critical editions. Each application is subject to the approval of the Degree Committee. For the MLitt degree not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography and appendices.

The thesis for the PhD is not to exceed 60,000 words in length (80,000 by special permission), exclusive of tables, footnotes, bibliography, and appendices. Double-spaced or one-and-a-half spaced. Single or double-sided printing.

The thesis for the MPhil in Biological Science is not to exceed 20,000 words in length, exclusive of tables, footnotes, bibliography, and appendices. Double-spaced or one-and-a-half spaced. Single or double-sided printing.

For the PhD Degree the thesis is not to exceed 80,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices. It is normally expected to exceed 40,000 words unless prior permission is obtained from the Degree Committee. Each page of statistical tables, charts or diagrams shall be regarded as equivalent to a page of text of the same size. The Degree Committee do not consider applications to extend this word limit.

For the Doctor of Business (BusD) the thesis will be approximately 200 pages (a maximum length of 80,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices).

For the MSc Degree the thesis is not to exceed 40,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices.

The thesis is not to exceed 80,000 words including footnotes, references, and appendices but excluding bibliography; a page of statistics shall be regarded as the equivalent of 150 words. Also excluded are title-page, acknowledgements, table of contents, preface, and abstract/summary of thesis. Only under exceptional circumstances will permission be granted to exceed this limit. Candidates must submit with the thesis a signed statement giving the length of the thesis.

For the PhD degree and the MD degree, not to exceed 60,000 words (or 80,000 by special permission of the Degree Committee), and for the MSc degree, not to exceed 40,000 words. These limits exclude figures, photographs, tables, appendices and bibliography. Lines to be double or one-and-a-half spaced; pages to be double or single sided.

The thesis is not to exceed, without the prior permission of the Degree Committee, 60,000 words including tables, footnotes and equations, but excluding appendices, bibliography, photographs and diagrams. Any thesis which without prior permission of the Degree Committee exceeds the permitted limit will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed 80,000 words for the PhD degree and the MLitt degree, including footnotes, references and appendices but excluding bibliography. Candidates must submit with the thesis a signed statement giving the length of the thesis. Only under exceptional circumstances will permission be granted to exceed this limit for the inclusion of an appendix of a substantial quantity of text which is necessary for the understanding of the thesis (e.g. texts in translation, transcription of extensive primary source material). Permission must be sought at least three months before submission of the thesis and be supported by a letter from the supervisor certifying that such exemption from the prescribed limit of length is absolutely necessary.

The thesis is not to exceed, without the prior permission of the Degree Committee, 80,000 words for the PhD degree and 60,000 words for the MSc or MLitt degree, including the summary/abstract.  The table of contents, photographs, diagrams, figure captions, appendices, bibliography and acknowledgements to not count towards the word limit. Footnotes are not included in the word limit where they are a necessary part of the referencing system used.

Earth Sciences:

The thesis is not to exceed, without the prior permission of the Degree Committee, 275 numbered pages of which not more than 225 pages are text, appendices, illustrations and bibliography. A page of text is A4 one-and-a-half-spaced normal size type. The additional 50 pages may comprise tables of data and/or computer programmes reduced in size.

If a candidate's work falls within the social sciences, candidates are expected to observe the limit described in the Department of Geography above; if, however, a candidate's work falls within the natural sciences, a candidate should observe the limit described in the Department of Earth Sciences.

Applications for the limit of length of the thesis to be exceeded must be early — certainly no later than the time when the application for the appointment of examiners and the approval of the title of the thesis is made. Any thesis which, without the prior permission of the Degree Committee, exceeds the permitted limit of length will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed, without the prior permission of the Degree Committee, 60,000 words including tables, footnotes, bibliography and appendices. The Degree Committee points out that some of the best thesis extend to only half this length. Each page of statistical tables, charts or diagrams shall be regarded as equivalent to a page of text of the same size.

The thesis is not to exceed 80,000 words for the PhD and EdD degrees and 60,000 words for the MSc and MLitt degrees, in all cases excluding appendices, footnotes, reference list or bibliography. Only in the most exceptional circumstances will permission be given to exceed the stated limits. In such cases, you must make an application to the Degree Committee as early as possible -and no later than three months before it is proposed to submit the thesis, having regard to the dates of the Degree Committee meetings. Your application should (a) explain in detail the reasons why you are seeking the extension and (b) be accompanied by a full supporting statement from your supervisor showing that the extension is absolutely necessary in the interests of the total presentation of the subject.

For the PhD degree, not to exceed, without prior permission of the Degree Committee, 65,000 words, including appendices, footnotes, tables and equations not to contain more than 150 figures, but excluding the bibliography. A candidate must submit with their thesis a statement signed by the candidate themself giving the length of the thesis and the number of figures. Any thesis which, without the prior permission of the Degree Committee, exceeds the permitted limit will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed 80,000 words or go below 60,000 words for the PhD degree and not to exceed 60,000 words or go below 45,000 words for the MLitt degree, both including all notes and appendices but excluding the bibliography. A candidate must add to the preface of the thesis the following signed statement: 'The thesis does not exceed the regulation length, including footnotes, references and appendices but excluding the bibliography.'

In exceptional cases (when, for example, a candidate's thesis largely consists of an edition of a text) the Degree Committee may grant permission to exceed these limits but in such instances (a) a candidate must apply to exceed the length at least three months before the date on which a candidate proposes to submit their thesis and (b) the application must be supported by a letter from a candidate's supervisor certifying that such exemption from the prescribed limit of length is absolutely necessary.

It is a requirement of the Degree Committee for the Faculty of English that thesis must conform to either the MHRA Style Book or the MLA Handbook for the Writers of Research papers, available from major bookshops. There is one proviso, however, to the use of these manuals: the Faculty does not normally recommend that students use the author/date form of citation and recommends that footnotes rather than endnotes be used. Bibliographies and references in thesis presented by candidates in ASNaC should conform with either of the above or to the practice specified in Cambridge Studies in Anglo-Saxon England.

Thesis presented by candidates in the Research Centre for English and Applied Linguistics must follow as closely as possible the printed style of the journal Applied Linguistics and referencing and spelling conventions should be consistent.

A signed declaration of the style-sheet used (and the edition, if relevant) must be made in the preliminary pages of the thesis.

PhD theses MUST NOT exceed 80,000 words, and will normally be near that length.

A minimum word length exists for PhD theses: 70,000 words (50,000 for MLitt theses)

The word limit includes appendices and the contents page but excludes the abstract, acknowledgments, footnotes, references, notes on transliteration, bibliography, abbreviations and glossary.  The Contents Page should be included in the word limit. Statistical tables should be counted as 150 words per table. Maps, illustrations and other pictorial images count as 0 words. Graphs, if they are the only representation of the data being presented, are to be counted as 150 words. However, if graphs are used as an illustration of statistical data that is also presented elsewhere within the thesis (as a table for instance), then the graphs count as 0 words.

Only under exceptional circumstances will permission be granted to exceed this limit. Applications for permission are made via CamSIS self-service pages. Applications must be made at least four months before the thesis is bound. Exceptions are granted when a compelling intellectual case is made.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, in all cases including footnotes and appendices but excluding bibliography. Permission to submit a thesis falling outside these limits, or to submit an appendix which does not count towards the word limit, must be obtained in advance from the Degree Committee.

The thesis is not to exceed 80,000 for the PhD degree and 60,000 words for the MSc or MLitt degree, both including footnotes, references and appendices but excluding bibliographies. One A4 page consisting largely of statistics, symbols or figures shall be regarded as the equivalent of 250 words. A candidate must add to the preface of their thesis the following signed statement: 'This thesis does not exceed the regulation length, including footnotes, references and appendices.'

For the PhD degree the thesis is not to exceed 80,000 words (exclusive of footnotes, appendices and bibliography) but subject to an overall word limit of 100,000 words (exclusive of bibliography, table of contents and any other preliminary matter). Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy. For the MLitt degree the thesis is not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography, appendices, table of contents and any other preliminary matter. Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy.

Criminology:

For the PhD degree submission of a thesis between 55,000 and 80,000 words (exclusive of footnotes, appendices and bibliography) but subject to an overall word limit of 100,000 words (exclusive of bibliography, table of contents and any other preliminary matter). Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy. For the MLitt degree the thesis is not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography, appendices, table of contents and any other preliminary matter. Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy.

There is no standard format for the thesis in Mathematics.  Candidates should discuss the format appropriate to their topic with their supervisor.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, including footnotes and appendices but excluding the abstract, any acknowledgements, contents page(s), abbreviations, notes on transliteration, figures, tables and bibliography. Brief labels accompanying illustrations, figures and tables are also excluded from the word count. The Degree Committee point out that some very successful doctoral theses have been submitted which extend to no more than three-quarters of the maximum permitted length.

In linguistics, where examples are cited in a language other than Modern English, only the examples themselves will be taken into account for the purposes of the word limit. Any English translations and associated linguistic glosses will be excluded from the word count.

In theses written under the aegis of any of the language sections, all sources in the language(s) of the primary area(s) of research of the thesis will normally be in the original language. An English translation should be provided only where reading the original language is likely to fall outside the expertise of the examiners. Where such an English translation is given it will not be included in the word count. In fields where the normal practice is to quote in English in the main text, candidates should follow that practice. If the original text needs to be supplied, it should be placed in a footnote. These fields include, but are not limited to, general linguistics and film and screen studies.

Since appendices are included in the word limit, in some fields it may be necessary to apply to exceed the limit in order to include primary data or other materials which should be available to the examiners. Only under the most exceptional circumstances will permission be granted to exceed the limit in other cases. In all cases (a) a candidate must apply to exceed the prescribed maximum length at least three months before the date on which a candidate proposes to submit their thesis and (b) the application must be accompanied by a full supporting statement from the candidate's supervisor showing that such exemption from the prescribed limit of length is absolutely necessary.

It is a requirement within all language sections of MMLL, and also for Film, that dissertations must conform with the advice concerning abbreviations, quotations, footnotes, references etc published in the Style Book of the Modern Humanities Research Association (Notes for Authors and Editors). For linguistics, dissertations must conform with one of the widely accepted style formats in their field of research, for example the style format of the Journal of Linguistics (Linguistic Association of Great Britain), or of Language Linguistic Society of America) or the APA format (American Psychology Association). If in doubt, linguistics students should discuss this with their supervisor and the PhD Coordinator.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, both excluding notes, appendices, and bibliographies, musical transcriptions and examples, unless a candidate make a special case for greater length to the satisfaction of the Degree Committee. Candidates whose work is practice-based may include as part of the doctoral submission either a portfolio of substantial musical compositions, or one or more recordings of their own musical performance(s).

PhD (MLitt) theses in Philosophy must not be more than 80,000 (60,000) words, including appendices and footnotes but excluding bibliography.

Institute of Astronomy, Department of Materials Science & Metallurgy, Department of Physics:

The thesis is not to exceed, without prior permission of the Degree Committee, 60,000 words, including summary/abstract, tables, footnotes and appendices, but excluding table of contents, photographs, diagrams, figure captions, list of figures/diagrams, list of abbreviations/acronyms, bibliography and acknowledgements.

Department of Chemistry:

The thesis is not to exceed, without prior permission of the Degree Committee, 60,000 words, including summary/abstract, tables, and footnotes, but excluding table of contents, photographs, diagrams, figure captions, list of figures/diagrams, list of abbreviations/acronyms, bibliography, appendices and acknowledgements. Appendices are relevant to the material contained within the thesis but do not form part of the connected argument. Specifically, they may include derivations, code and spectra, as well as experimental information (compound name, structure, method of formation and data) for non-key molecules made during the PhD studies.

Applicable to the PhDs in Politics & International Studies, Latin American Studies, Multi-disciplinary Studies and Development Studies for all submissions from candidates admitted prior to and including October 2017.

A PhD thesis must not exceed 80,000 words, and will normally be near that length. The word limit includes appendices but excludes footnotes, references and bibliography. Footnotes should not exceed 20% of the thesis. Discursive footnotes are generally discouraged, and under no circumstances should footnotes be used to include material that would normally be in the main text, and thus to circumvent the word limits. Statistical tables should be counted as 150 words per table. Only under exceptional circumstances, and after prior application, will the Degree Committee allow a student to exceed these limits. A candidate must submit, with the thesis, a statement signed by her or himself attesting to the length of the thesis.

doctoral dissertation word count

Average word count of a dissertation

  • November 15, 2018
  • evalantsoght_uw8lmy
  • Uncategorized

For some reason, I always thought a doctoral thesis is about 100,000 words in length (and I’ve taken that number as a reference for my book as well). However, I wanted to test this assumption, so I ran a poll about the topic. From the comments, I learned that word count limits are common in the UK (mostly), and that they differ across disciplines.

Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation .

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

  • master the academic foundational skills (research, writing, ability to navigate different modalities)
  • time-management skills and the ability to focus on reading and writing
  • determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.
