Tips for fiction authors

Romance novels typically run 50k–80k in 20–30 chapters. Epic fantasy often exceeds 100k in 30–50 chapters. Know your genre before planning.
Shorter chapters (2,000–3,000 words) create a page-turner feel on Kindle. Longer chapters (4,000–6,000) suit literary and epic fantasy pacing.
Track cumulative word count as you draft in Story Studio. Falling behind early is easier to correct than discovering a 20k shortfall in act three.
Use chapter targets as guardrails, not rules. A climactic chapter can be half the target length if the scene demands it.
Run the KDP page estimator after setting your target length to preview print page count and spine width.
