Dissertation & Thesis Word Limits

From a 10,000-word undergrad dissertation to a 100,000-word PhD

Dissertation limits are set by each institution, but the ranges are consistent: undergraduate dissertations commonly cap at 10,000-15,000 words, master's theses at 15,000-25,000, and PhD theses at 80,000-100,000 in the humanities (often less in the sciences). Abstracts for deposited theses are commonly capped at 350 words.

Frequently Asked Questions

Do references count toward a dissertation word limit?

Usually the bibliography is excluded and in-text citations count, but institutions differ - your course handbook is the only authoritative answer, and the difference can be thousands of words.

Is there a tolerance on dissertation word limits?

Many universities allow up to 10% over; many others penalize from the first excess word. Treat the stated limit as absolute unless your handbook explicitly grants tolerance.
