This is the practical how to format a book for KDP guide: margins, bleed, fonts, page numbers, ebook + paperback — with a desktop workflow that scales.
1. Decide paperback vs ebook (or both)
KDP accepts separate files. Best practice: one manuscript project that can export both print PDF and EPUB/Kindle.
2. Pick trim size early
Common fiction sizes include 5×8, 5.5×8.5, and 6×9. Changing trim late reflows everything. Manusly includes multiple trim presets so you can preview before locking cover design.
3. Set margins and bleed
- Inside (gutter) margin grows with page count
- Outside/top/bottom must meet KDP minimums
- Full-bleed images need bleed beyond trim
4. Typography that survives Kindle
Embed licensed fonts for print; keep ebook CSS sane. Avoid text boxes as layout hacks.
5. Front matter & TOC
Title page, copyright, optional dedication, then a generated TOC from real headings — not a typed list that drifts.
6. Preview before upload
Use print preview and device preview. Catch image clipping and chapter title orphans before Amazon’s online previewer surprises you.
7. Export and upload
- Export print PDF for paperback interior.
- Export EPUB/Kindle for ebook.
- Upload in KDP, review online previewer, fix in your editor, re-export.
