Use the final interior before sizing the cover
KDP paperback cover width depends on trim width, paper/interior type and final page count because the page count controls spine width. The cover also includes 0.125 in bleed on the two outer sides and top/bottom. Books below 79 pages should not include printed spine text.
- Finalize the interior.Export or format the interior first so the page count is stable.
- Choose the exact trim and paper type.Changing either can change the cover or spine requirement.
- Calculate the full cover.Use the workspace for full dimensions, spine, pixels and mismatch checking.
- Compare with KDP's current template.Use the official cover calculator/template as the final provider-controlled check.
What the result is useful for
KDP Cover Pixels Calculator converts book-production inputs into dimensions or cost values that can be checked against the publishing provider before upload.
How the calculation works
KDP full-cover physical dimensions are calculated first, then multiplied by the chosen raster PPI.
What this calculator cannot know
KDP controls the final acceptance rules. Recheck Amazon’s current cover template/calculator after the interior is final, especially after any page-count or trim-size change.
