A thesis is a shorter research project for a Master’s degree, whereas a dissertation is an in-depth, original research project for a doctoral degree. However, it is important to note that the naming convention is reversed in some regions like the UK and parts of Europe, where a Master’s project is called a dissertation and a PhD project is a thesis. Also, a National University Guide notes that a thesis is the stepping stone for a master’s degree, while a dissertation is the final capstone for a PhD.
The following are the key differences:
Academic Level:
- A thesis is written to complete a master’s program,
- A dissertation is written to earn a PhD or doctorate.
Research and scope:
- A thesis mostly analyses and synthesises existing research to answer a specific question
- A dissertation requires entirely new, original research that adds a unique contribution to the field.
Length:
- A thesis is shorter, usually around 40 to 100 pages
- A dissertation is much longer and more detailed, often spanning 200 to 400+ pages.
Defense:
- Both require a formal defence before a panel of experts, but a doctoral defence is typically more rigorous and extensive.
Despite the structural differences in scale, both documents function as comprehensive graduate-level research papers. They require an introduction, literature review, methodology, data analysis, and a formal defence before a university committee to secure graduation.

Frequently Asked Questions
1. Is a dissertation harder than a thesis?
Generally, a dissertation is more demanding because it usually involves more extensive research, original findings, and a deeper contribution to the subject area. However, requirements vary by university and country.
2. Can a Master’s student write a dissertation?
Yes. In the UK and many other countries, a Master’s research project is commonly called a dissertation. The exact terminology depends on the university and academic system.
3. How long is a thesis or dissertation?
The required length varies by university, subject, and degree level. Master’s projects are generally shorter, while doctoral research is typically much longer and more detailed.
4. Do both a thesis and dissertation require original research?
Both can involve original research. A doctoral dissertation, however, is normally expected to make a significant original contribution to the field, while a Master’s project may focus more on analysing and applying existing research.
5. Do you have to defend a dissertation or thesis?
Doctoral dissertations normally require a formal oral defence, often called a viva. Some Master’s programmes may also require a presentation or defence, depending on the university.
6. What is the main difference between a thesis and a dissertation?
The main differences are usually the academic level, research scope, expected originality, length, and defence requirements. However, the terms can mean different things depending on the country.
7. Is a dissertation the same as a PhD thesis?
Not always. In the UK, a PhD research project is generally called a thesis, while a Master’s research project is usually called a dissertation. In some countries, these terms are used the other way around.
8. Which one takes longer to complete, a thesis or dissertation?
A doctoral-level research project generally takes longer because it requires more extensive research, analysis, writing, and often several stages of review before submission and defence.
