What Determines PhD Dissertation Length?

The word count of a PhD dissertation is influenced by numerous different elements:

✔ Field of Study – Dissertations in humanities take more time as compared to STEM dissertations.

✔ University Guidelines – Few universities have preset word limits.

✔ Research Scope – Wider research areas may have longer discussion sections.

✔ Methodology Used – Qualitative research usually leads to lengthier dissertations.

✔ Publication Requirements – Several universities employ a journal-style dissertation, so they follow a style book. Imagine if a university assigned each student a book with a specific structure designed for orderly filing, in anticipation of what they wish to publish, that would be something, huh?

Next up, we will analyze averages of PhD dissertation lengths according to each discipline.
