"Kindle Unlimited (KU) pays authors based on Kindle Edition Normalized Pages (KENP) read by subscribers. Optimizing your interior layout formatting can improve your page-read metrics and overall royalties."

Core Key Takeaways

  • Understanding KENP Calculation Rules
  • Formatting Elements that Improve Page-Reads
  • Tracking Reader Retention and Catalog Read-Through

1. Understanding KENP Calculation Rules

Amazon calculates page counts based on font density, line spacing, and graphics. Standard fiction formatting yields standard KENP page metrics.

  • Format books with industry-standard margins and line spacing.
  • Avoid adding unnecessary pages or spacing that flags reviews.
  • Embed images or tables to increase KENP page values.

2. Formatting Elements that Improve Page-Reads

Use readable font sizing, clean paragraph spacing, and styled headings to keep readers engaged and turning pages through your catalog.
