1. Degree Requirement
A dissertation is required for a PhD program.
A thesis is required for a Master’s program.
2. Research Approach
A dissertation requires students to conduct original research and perform in-depth analysis.
A thesis is primarily based on existing research and established studies.
3. Length
A dissertation is generally around 100 pages or more.
A thesis usually ranges from 100 to 300 pages, depending on discipline and institution.
4. Research Contribution
A dissertation expands upon existing research with original contributions.
A thesis demonstrates the student’s understanding and interpretation of existing knowledge.
5. Timeline
A dissertation is typically completed toward the very end of a PhD program.
A thesis is completed as part of a Master’s degree before graduation.
Knowing these differences helps students plan their academic workload, research depth, and long-term goals more effectively.
