When a student is assigned a PhD thesis, one of the first questions he/she asks is, “How long is a PhD thesis?”. In this article, we will discuss all the essentials concerning PhD dissertation writing and answer the trickiest questions you may have, such as “How long are PhD dissertations?”,
What Is the Typical Length of a PhD Thesis?
The number of pages for a PhD thesis may vary according to the field of study, university guidelines, and nature of the doctoral research. Generally, it ranges from 80,000 to 100,000 words, and this number includes references, tables, and appendices. This is about 200 to 300 pages, depending on the formatting and the complexity of the research itself. Theses in humanities and social sciences tend to be longer due to their extensive literature reviews and theoretical discussions.
Average Word Count for a PhD Thesis in STEM
But how long is a dissertation for PhD in STEM? STEM fields usually focus on experimental data, and STEM theses may be shorter, perhaps 40,000-60,000 words. Before getting down to academic writing, it is highly recommended that you check the specific institutional PhD requirements set by your professor because some may have strict word limits.
6 Factors That Influence PhD Thesis Length
How long should a dissertation be? The answer usually depends on some factors. Here are some key factors that may influence the volume of your paper.
- Field of study. Doctoral theses in the humanities and social sciences often require extensive literature reviews and theoretical discussions, which make them a bit longer. STEM fields may focus more on concise experimental data.
- Study scope and depth. The complexity of the study questions, methodologies, and findings influence the dissertation length. Comprehensive studies with large datasets are more extended.
- Writing style and structure. Concise academic writing with well-organized sections can result in a shorter dissertation. At the same time, profound explanations and detailed analysis can increase the number of pages.
- Appendices and supplementary material. Extensive appendices with raw data, questionnaires, or detailed methodology can contribute significantly to the overall number of pages.
- Supervisor requirements. Supervisors may have specific preferences for the depth of analysis, number of pages, and details. This can influence the overall word count of your dissertation.
- Type of research. Qualitative doctoral research often requires more detailed descriptions and discussions. At the same time, quantitative research is often more concise, with focused data presentation.
How Thesis Length Varies Across Universities
Universities often set word limits for theses, which can vary by department. The number of pages required for a dissertation can vary across universities due to differences in academic standards, field expectations, and institutional guidelines.
- University-specific guidelines. Each university sets its own rules regarding dissertation length. The word limits usually vary between different departments. Some may set the limit at 80,000 words, but others may allow up to 100,000 words.
- Field of study requirements. Even within the same university, dissertation word count may vary by discipline. Humanities and social sciences usually expect up to 100,000 words, but sciences may need around 40,000–60,000 words.
- Doctoral program type. Some universities offer structured PhD programs with embedded coursework, which might result in shorter theses due to the prior publication of related research papers. Others, especially traditional programs, may require more extensive research.
- International variations. British and Australian universities typically adhere to stricter word count limits. At the same time, institutions in the US focus more on the quality and depth of the research without paying much attention to the word count.
- Language and formatting norms and requirements. Universities with different language requirements or specific formatting rules may impact overall dissertation length.
As you can see, there are a lot of factors that may influence the number of pages needed for your dissertation, and you should always review your specific university and departmental guidelines when planning the scope and structure of your dissertation.
Differences in PhD Thesis Length by Discipline
The word count for a PhD thesis also varies by discipline based on the nature of the study, the academic writing style, and the type of data presented.
Humanities and Social Sciences
Doctoral theses in fields like history, literature, sociology, and psychology are often the longest. Their volumes range from 80,000 to 100,000 words. Due to their extensive literature reviews, theoretical discussions, and in-depth qualitative analysis, these papers require more extensive texts.
STEM (Science, Technology, Engineering, and Mathematics)
Theses in STEM fields are often shorter. They typically range from 40,000 to 60,000 words. They focus on the concise presentation of experimental data, methods, and results with various figures and tables.
Arts and Design
These disciplines usually have creative components, and theses in these areas can range from 30,000 to 50,000 words. The number of pages may vary depending on the balance between practical work and written analysis.
Business and Economics
These theses usually range from 50,000 to 80,000 words. Business and Economics papers often include case studies, quantitative analysis, and comprehensive reviews of different business models or economic theories.
Law
Legal PhD theses range from 70,000 to 100,000 words. These papers are often longer due to detailed case law analysis, legal theory discussions, and policy implications.
Medicine and Health Sciences
If you are assigned a Medicine or Health Science dissertation, this type of paper will be about 50,000-70,000 words. As they are focused on clinical data, patient studies, or laboratory findings, the volume may be quite large.
These variations involve the specific needs of each discipline. Some require more narrative detail and theoretical context, while others emphasize brevity and data-centric presentations, and these points offer their own PhD requirements.
How to Determine the Right Length for Your PhD Thesis
Determining the correct number of pages for your PhD thesis involves balancing academic guidelines, the scope of your research, and the expectations within your discipline. Thus, in order to come up with the dissertation your professor expects, you have to consider all the essential PhD requirements and instructions.
