KDP paperback preflight checklist
Tick through what KDP rejects or warns about in a paperback interior PDF before you upload it.
The margins below depend on it.
| Inside margin (gutter), minimum | |
|---|---|
| Outside, top and bottom, no bleed | |
| Outside, top and bottom, with bleed | |
| Bleed to add |
How to use it
- Export your final PDF. Check the file you will upload, not a draft.
- Open it in a PDF viewer. The document properties show page size and fonts; scrolling shows images, blank pages and margins.
- Tick each item you have confirmed. Every item quotes KDP and links to the page it comes from.
Your ticks stay in this browser only. KDP's own Print Previewer, after upload, is the final check.
