Designing your book in Canva but unsure what size to make it?

This guide shows you exactly how to set up your KDP book in Canva, so your files fit Amazon’s print requirements.

You’ll work out your trim size, bleed and margins before you start. Then you’ll set up your interior pages in Canva and keep your text inside the safe margins on left and right pages.

You’ll also build your cover with the right spine width and guide positions, export your files correctly, and upload them to KDP.

It includes a sizing table, cover size formulas with a worked example, a page-count quick reference for spine width, and a checklist to tick off before you export.
