KDP paperback preparation guides

Plan your page count

Estimate how text and images affect the length of a paperback. Front matter, blank pages and full-page illustrations all count toward the physical page total. A word-based estimate is a planning aid; the exported PDF supplies the final count.

Choose trim, bleed and margins

Trim describes the finished page. Bleed extends artwork beyond the cut edge, while the gutter keeps text away from the binding. These settings affect the interior layout and must agree with the choices you make during upload.

Check the inside gutter for your page count

Calculate the full wrap cover

A paperback cover contains the back, spine and front in one file. Spine width depends on page count and paper. Calculate it after finishing the interior, keep the barcode area clear and regenerate the cover when the page total changes.

Review files before publishing

Open both PDFs, inspect page order and text wrapping, and resolve missing assets or low-resolution warnings. Match the file geometry to the print settings in your KDP account. Review AI-content disclosure, use the upload previewer and order a printed proof before releasing the book.
