How Many Words is a Dissertation?

Writing a dissertation is one of the most challenging and significant tasks in a student’s academic career.

One of the most common questions that arise when embarking on this daunting journey is, “How many words should my dissertation be?”

This question delves into a complexity often underestimated, as the length of a dissertation can fluctuate significantly, contingent upon various factors such as the field of study and the degree level and specific institutional requirements.

In this blog, we’ll explore these variables in detail, providing a comprehensive guide to understanding dissertation lengths.

 Understanding the Basics

A dissertation, also known as a thesis in some countries, is a substantial piece of academic writing based on original research.

It is typically required for the completion of a doctoral degree (Ph.D.), but in some cases, master’s students also write dissertations.

The purpose of a dissertation is to contribute new knowledge or theories to a specific field of study.

 Factors Influencing Dissertation Length

1. Degree Level

– Undergraduate Dissertation: In some universities, undergraduate students may be required to write a dissertation, typically as a final-year project. These dissertation writing help are usually shorter, ranging from 8,000 to 15,000 words.

– Master’s Dissertation: A master’s dissertation is more comprehensive than an undergraduate dissertation. The word count typically ranges from 15,000 to 25,000 words, depending on the field of study and institutional requirements.

– Doctoral Dissertation (Ph.D.): The length of a Ph.D. dissertation is significantly longer, reflecting the depth of research and the originality required. These dissertations usually range from 70,000 to 100,000 words, though this can vary considerably.

2. Field of Study

– Humanities and Social Sciences: Dissertations in fields like literature, history, sociology, and psychology tend to be longer. They often range between 80,000 and 100,000 words due to the extensive literature review and qualitative research methods employed.

Sciences and Engineering: Dissertations in scientific and engineering disciplines are usually shorter, often between 40,000 and 80,000 words. These fields often rely more on quantitative data and research paper writing service, which can be presented more concisely.

– Interdisciplinary Studies: For students engaged in interdisciplinary research, the word count can vary widely. It often depends on the balance between the disciplines involved and the specific requirements of their program.

3. Institutional Requirements

– Different universities have different guidelines for dissertation length. It’s crucial to consult your institution’s handbook or speak with your advisor to understand the specific requirements.

Some institutions provide a word count range, while others might have a more flexible approach.

4. Research Scope

– The scope of your research also impacts the length of your dissertation. A broader research scope might require a more extensive literature review and more detailed data analysis, leading to a longer dissertation.

 Typical Dissertation Structures and Their Word Counts

Understanding the typical structure of a dissertation can also help gauge the word count. While the structure can vary depending on the discipline and institution, most dissertations follow a similar format:

1. Introduction (10% of total word count)

– The introduction sets the stage for your research, outlining the research question, objectives, and significance of the study. For a 70,000-word dissertation, the introduction would typically be around 7,000 words.

2. Literature Review (20-30% of total word count)

– The literature review provides a comprehensive overview of existing research on your topic. It identifies gaps in the literature that your research aims to fill. For a 70,000-word dissertation, the literature review might range from 14,000 to 21,000 words.

3. Methodology (15-20% of total word count)

– The methodology section explains how you conducted your research. This includes your research design, data collection methods, and data analysis techniques. For a 70,000-word dissertation, this section would be around 10,500 to 14,000 words.

4. Results (15-20% of total word count)

– The results section presents the findings of your research. For a 70,000-word dissertation, this section would typically be around 10,500 to 14,000 words.

5. Discussion (15-20% of total word count)

– The discussion section interprets your results, explaining their significance and how they relate to your research question. For a 70,000-word dissertation, this section would be around 10,500 to 14,000 words.

6. Conclusion (5-10% of total word count)

– The conclusion summarizes your research and its implications and may suggest areas for future research. For a 70,000-word dissertation, the conclusion would be around 3,500 to 7,000 words.

7. References and Appendices

– These sections do not typically count towards the word limit, but they are essential components of your dissertation. References include all the sources cited in your work, while appendices might contain supplementary material such as raw data, questionnaires, or additional analysis.

 Real-World Examples

To provide a clearer picture, let’s look at some real-world examples of dissertation lengths across different disciplines and degree levels:

1. Undergraduate Example: A final-year psychology student at a UK university might be required to write a dissertation of 10,000 words, including sections such as introduction, literature review, methodology, results, discussion, and conclusion.

2. Master’s Example: A master’s student in business administration might be required to write a dissertation of 20,000 words, with a more detailed literature review and analysis compared to the undergraduate level.

3. Ph.D. Example: A Ph.D. candidate in history at a US university might write a dissertation of 90,000 words, reflecting the extensive research and analysis required in this field.

 Strategies for Managing Dissertation Length

Writing a dissertation of any length can be overwhelming. Here are some strategies to help you manage and achieve your target word count:

1. Create a Detailed Outline

– Before you start writing, create a detailed outline of your dissertation. This will help you structure your work and allocate word counts to each section.

2. Set Word Count Goals

– Break down your writing into manageable chunks by setting daily or weekly word count goals. Keeping this in mind will aid in maintaining focus and achieving consistent advancement.

3. Prioritize Quality Over Quantity

– While meeting the word count is important, ensure that every word adds value to your dissertation. Avoid unnecessary filler and focus on presenting your research clearly and concisely.

4. Revise and Edit Ruthlessly

– After completing your first draft, revise and edit your work to refine your arguments and improve clarity. This might involve cutting out redundant sections or expanding on key points.

5. Seek Feedback

– Regularly seek feedback from your advisor or peers. They can provide valuable insights and help you identify areas that need improvement.


The length of a dissertation can vary widely depending on multiple factors, including the degree level, field of study, and institutional requirements.

Understanding these factors and the typical structure of a dissertation can help you gauge the appropriate word count for your research.

By creating a detailed outline, setting word count goals, prioritizing quality, and seeking feedback, you can effectively manage the length of your dissertation and produce a comprehensive and impactful piece of academic work.

Whether you’re writing a 10,000-word undergraduate dissertation or a 90,000-word Ph.D. dissertation, remember that the quality of your research and the clarity of your writing are paramount.

By focusing on these aspects, you can ensure that your dissertation makes a meaningful contribution to your field of study.
