HOW THIS TOOL WORKS

A practical check before you print.

Planning templates only, not upload-ready cover artwork. Odd page counts are rounded up to even. Scope: five common paperback trims for Amazon.com; no hardcover or marketplace-wide eligibility guarantee. Cover bleed is 0.125 in on each outside edge; interior bleed adds 0.125 in to width and 0.25 in to height. Official specifications checked September 8, 2026. Cover specifications · Interior and page-count limits. Standard-color spine thickness follows the dedicated cover page (0.002252 in/page); always compare your final file with the official KDP template.

How to use this tool

  1. Choose a supported trim, page count, ink and paper type.
  2. Review cover spread, spine and interior measurements and page-count limits.
  3. Download a reference template and compare your finished design with the official Amazon KDP template.

Is the KDP template ready to upload as a finished cover?

No. It is a design reference with measurement guides. Replace guides with artwork and check the final file against the official KDP template and current submission requirements.
