Ever stared at your dissertation word count and wondered, “how long should a literature review be?” You’re not alone. It’s one of those questions every student asks but rarely gets a clear answer for.
Rule of thumb: your literature review is usually 20–30% of your total dissertation. So if your dissertation is 10,000 words, think 2,000–3,000 words. Enough to show you’ve done your homework, but not so much that you drown your own research in a sea of summaries.
Focus matters more than exact length. Cover the key studies, highlight gaps, and show how your work fits in. It’s not just a list of sources—it's your chance to tell the story of your field and justify your research.
Pro tip: if you’re stuck, outline first. Group studies by theme, debate, or methodology. Then write. You’ll find the word count naturally falls into the right range without forcing it.
