the straightforward answer to how long should a literature review be is roughly 20 to 30 percent of your total dissertation word count — around 2,000 to 3,000 words for a 10,000 word dissertation and between 3,000 and 6,000 words at masters level. always check your module handbook first though because your institution's own guidelines will always be more accurate than any general rule you find online.
what matters far more than hitting a specific number is whether your how long should a literature review be target is filled with genuinely critical writing that engages with key debates, identifies real gaps in existing research, and builds a convincing case for your own research question — because that is what your markers are actually grading you on.
