KDP publishing checklist

Work through this in order and an upload day stops being a day of rejections. Flumyngo generates or checks every item below.

1. Manuscript

  • Final chapter order, titles and consistent headings.
  • No gap markers or internal notes left in the text.
  • Quality pass done: pacing, repetition, filler, point of view, continuity.

2. Front and back matter

  • Title page, copyright and edition notice, dedication.
  • Bibliography or source notes for nonfiction, figure list where relevant.
  • About the author, also-by list, and a call to review.

3. Print interior

  • Trim size chosen and applied throughout.
  • Bleed on any full-page image; margins and gutter appropriate to page count.
  • Figures numbered with captions and credits.

4. Cover wrap

  • Spine width from final page count and paper stock; spine text only above the minimum page count.
  • Back cover blurb, pull quote, author bio and barcode clear zone.
  • Bleed on all outside edges.

5. Ebook

  • Validated EPUB: single title page, correct spine order, cover entry present.
  • Working table of contents and internal links.

6. Listing

  • Description formatted and inside the length limit.
  • Seven keyword phrases, two categories, BISAC codes, age and grade range where relevant.
  • Series name and number, contributors, language, publication date.
  • Pricing per marketplace and royalty plan chosen.

7. Before you hit publish

  • Order or download a proof and read the first and last page of every chapter.
  • Check the cover at thumbnail size — the title must survive being tiny.
  • Have your launch emails, social posts and quote graphics ready.

Questions writers ask

How wide should my spine be?

Spine width is page count multiplied by the caliper of your paper stock. Flumyngo calculates it from your real page count and stock, adds bleed, and marks the barcode clear zone on the wrap.

Why does KDP reject my EPUB?

Usually a broken spine reference, a missing cover entry or duplicate title pages. The EPUB is structurally validated before download, and common issues are reported in plain language.

How many keywords and categories do I need?

KDP takes seven keyword slots and two categories at upload, plus BISAC codes. The listing builder keeps you inside those limits and checks description length.
