Key takeaways
- Choose trim size, paper and ink before finalizing the layout.
- Use margins and bleed appropriate to your page count and artwork.
- Preview both the interior and cover using KDP’s current requirements.
1. Choose the print format
Select your trim size, binding, paper and ink based on the book and its readers. Page count and paper choice affect the physical book and the width of a printed spine.
KDP offers manuscript templates for common sizes. Use the current template or specifications for your selected format rather than assuming every book uses the same margins.
2. Prepare the interior
Set the inside and outside margins for the page count and layout. If images or backgrounds extend to the page edge, follow KDP’s bleed instructions for the entire interior file.
Check page order, headings, page numbers and images at their intended print size. Review the exported PDF rather than relying only on the editor preview.
3. Prepare and check the cover
A printed cover includes the back, spine and front. Use KDP’s cover calculator or template for the actual trim, page count and paper type, and leave room for its barcode requirements.
Upload the files to KDP and inspect the print previewer. Resolve warnings and review each page before approving the book.
Frequently asked questions
Do all KDP books use the same margins?
No. Margin requirements depend on the book’s page count and whether the interior uses bleed. Check the current KDP specifications for your book.
Why does my cover spine width change?
The spine depends on the final page count and paper type. Generate a new cover template when those settings change.
