The Ultimate KDP Formatting Checklist


Before you upload your manuscript to Amazon KDP, run it through this 21-point checklist to reduce the risk of rejection by the automated review system.

The Checklist

1. File & Format Basics

  • Final file is exported as a PDF (for print) and EPUB (for digital).
  • Print PDF is saved as PDF/X-1a:2001.
  • All fonts are embedded in the PDF.

2. Page Setup & Margins

  • Trim size matches your KDP setup selection (e.g., 6" x 9").
  • Gutter margin is correct for your final page count.
  • Top, bottom, and outside margins are at least 0.25" (0.5" recommended).
  • If using bleed, 0.125" is added to the top, bottom, and outside edges.

3. Front Matter

  • Title page matches the metadata entered in KDP exactly.
  • Copyright page includes year and author name.
  • Table of Contents is generated automatically (not typed manually).
  • Print TOC uses dot leaders and page numbers.
  • Digital TOC uses hyperlinks and no page numbers.

4. Typography & Layout

  • Chapter titles use a consistent Heading style.
  • First paragraphs of chapters are NOT indented.
  • Subsequent paragraphs are indented consistently (e.g., 0.3").
  • Scene breaks use a consistent visual marker (e.g., ***).
  • No more than 3 consecutive hyphens are used (replace with an em-dash).

5. Images & Graphics

  • All interior images are at least 300 DPI.
  • Color images are converted to CMYK (for print).
  • Images intended to bleed extend fully to the edge of the bleed zone.
  • No text overlays on images extend into the 0.25" safe zone.
