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.
