I’m currently drafting the literature review section of my dissertation and keep getting mixed advice about how long should a dissertation literature review be. Some sources suggest a percentage of the total word count, while others say it depends entirely on the discipline and research design. For those who’ve already completed their dissertations (or supervise them), what’s a reasonable length for a literature review? Are there general guidelines by field, or is it purely up to the university and supervisor? Any examples or tips on balancing depth with conciseness would be really helpful.
From what I’ve read so far, opinions on how long should a dissertation literature review be seem to vary widely. In some disciplines, it’s recommended to dedicate around 20% to 40% of the total word count to the literature review, while in others it’s much shorter and more focused. I’m also seeing differences in whether the review should be a single standalone chapter or spread across multiple sections of the dissertation, which makes it even harder to judge the ideal length.
I’d really appreciate hearing how others handled this question in practice. Did you receive clear guidance on how long should a dissertation literature review be from your supervisor or department? How did you balance covering key theories and studies without overloading the chapter with unnecessary detail? Any advice on structuring, prioritizing sources, and trimming excess material would be extremely helpful.
