Have you ever asked yourself what’s the difference between a dissertation and a thesis? Though both terms refer to significant research projects required to complete a degree, their usage and requirements vary depending on the country you are studying in. This article will delve into the differences between a dissertation and a thesis, provide insights into what each entails, and offer examples to help clarify their unique aspects. By the end, you’ll have a clearer understanding of dissertation vs thesis and how to approach each in your academic journey.
Thesis or Dissertation? It Depends on Where You Are
The terms “dissertation” and “thesis” are often used interchangeably, with meanings varying by country and university. Different English-speaking countries, such as those using British or American English, apply these terms differently. Typically, in British-based academic systems, a dissertation is written for undergraduate or master’s degrees, while a thesis is for a PhD. Conversely, in American-based systems, the usage is reversed. However, the terms can vary even within institutions or departments.
What is a Dissertation?
In the UK, a dissertation is a substantial piece of written research typically undertaken at the end of a bachelor’s or master’s degree. It involves a thorough investigation into a specific topic, requiring the student to conduct independent research, analyse data, and present findings in a structured format.
Key Features of a Dissertation:
- Scope and Depth: A dissertation generally focuses on a narrower topic than a thesis and is less comprehensive in terms of research depth.
- Length: The length of a dissertation varies depending on the level of study. For a bachelor’s degree, it might be around 8,000 to 12,000 words, while for a master’s degree, it can range from 15,000 to 20,000 words.
- Research Focus: Dissertations often involve a literature review, methodology, results, and discussion sections. The research conducted is usually original but on a smaller scale than a thesis.
- Objective: The primary aim is to demonstrate the student’s ability to conduct independent research and to critically engage with existing literature and research methodologies.
Example of a Dissertation:
An example dissertation topic for a master’s degree in psychology might be: “an investigation into the relationship between early exposure and brand loyalty.” This would involve reviewing existing literature on the topic, conducting surveys, analysing the data, and presenting the findings.

What is a Thesis?
A thesis in the UK is a comprehensive research project required to complete a PhD. It represents a significant contribution to the existing body of knowledge in a particular field and demonstrates the candidate’s ability to conduct original, in-depth research.
Key Features of a Thesis:
- Scope and Depth: A thesis is more extensive and in-depth than a dissertation. It involves original research that contributes new knowledge or theories to the field.
- Length: A PhD thesis can be substantial in length, often ranging from 60,000 to 100,000 words, depending on the discipline and research topic.
- Research Focus: A thesis requires a detailed literature review, a clear research methodology, comprehensive data analysis, and a discussion of the findings. The research conducted should fill a gap in the existing literature.
- Objective: The main aim is to demonstrate the candidate’s ability to conduct significant, original research and to make a substantial contribution to the academic field.
Example of a PhD Thesis:
A PhD example thesis in the field of environmental science might be: “Assessing the Long-Term Impacts of Climate Change on Coastal Erosion in the UK.” This would involve extensive fieldwork, data collection and analysis, and the development of new models or theories related to climate change and coastal erosion.
Dissertation vs Thesis: A Detailed Comparison
Purpose and Scope
- Dissertation: The purpose of a dissertation is to demonstrate the student’s ability to conduct independent research on a specific topic, critically engage with existing literature, and present findings in a coherent manner. The scope is narrower and focuses on a specific aspect of a broader topic.
- Thesis: The purpose of a thesis is to contribute new knowledge or theories to the field. It requires comprehensive and original research, aiming to fill gaps in the existing literature. The scope is broader and more in-depth.
Length and Complexity
- Dissertation: Typically shorter, a dissertation for a master’s degree ranges from 15,000 to 20,000 words. It involves a literature review, methodology, results, and discussion sections.
- Thesis: A PhD thesis is significantly longer, ranging from 60,000 to 100,000 words. It includes a detailed literature review, extensive data analysis, and a comprehensive discussion of findings.
Research Requirements
- Dissertation: Requires independent research but on a smaller scale. The research is original but often builds on existing studies and theories.
- Thesis: Requires extensive original research that contributes new insights or theories to the field. The research should be substantial and fill a gap in the existing literature.
Academic Contribution
- Dissertation: The primary aim is to demonstrate the ability to conduct independent research and to critically analyse existing literature. The contribution to the academic field is often more modest.
- Thesis: The aim is to make a significant contribution to the academic field, providing new knowledge, theories, or models. The thesis should have a substantial impact on the discipline.
Writing Your Dissertation or Thesis
Writing a dissertation or thesis can be a daunting task, but with careful planning and organisation, it is achievable. Here are some tips to help you through the process:
1. Start Early
Begin your research and writing as early as possible. This allows ample time to explore your topic, conduct research, and refine your arguments.
2. Develop a Clear Research Question
Your research question should be specific, relevant, and feasible. It will guide your research and provide a clear focus for your dissertation or thesis.
3. Conduct a Thorough Literature Review
Review existing literature to identify gaps in the research and to position your work within the broader academic context. This will also help you build a strong theoretical framework for your study.
4. Choose the Right Methodology
Select a research methodology that is appropriate for your research question and objectives. Clearly explain your methods and justify your choices.
5. Stay Organised
Keep your research materials, notes, and drafts well-organised. Use project management tools or software to track your progress and deadlines.
6. Seek Feedback
Regularly seek feedback from your supervisor or peers. This will help you refine your arguments and improve the quality of your work.
7. Edit and Proofread
Carefully edit and proofread your dissertation or thesis to ensure it is free of errors and clearly presented. Consider seeking professional editing services if needed.
To Sum Up
A dissertation, required for bachelor’s and master’s degrees, involves independent research on a specific topic, while a thesis, required for a PhD, involves extensive original research that contributes new knowledge to the field. Both require careful planning, organisation, and dedication.
