A dissertation length varies depending on the academic level and discipline. Typically:
- Undergraduate dissertations are about 8,000 to 15,000 words.
- Master's dissertations usually range from 12,000 to 50,000 words.
- PhD dissertations are much longer, typically between 70,000 and 100,000 words, often equivalent to a book-length work or 100-300 pages.
The exact length can differ by field, with STEM dissertations generally shorter and humanities/social sciences dissertations often longer due to the depth of literature review and theoretical analysis.
