Book Cover Builder
A full wrap cover page, sized from your page count
What it does
- Calculates the spine width from the page count, paper and binding using per-page factors for each platform
- Adds one cover page at the exact full wrap size, with bleed, spine and safe zone guides
- Shows a summary (cover size in inches and pixels, spine, trim, page count, paper, rules version) that you can copy into the publishing form
- Pro: marks a barcode box (2 x 1.2 in) at the bottom right of the back cover
- Pro: IngramSpark spine width can be pasted from the IngramSpark template generator
- Pro: Resize cover writes a new page at the new size and moves your elements to match
How to use it
- Open a design and open Book Cover Builder from the Apps tab.
- On the New cover tab pick the Trim size, enter the Page count, and choose Paper, Binding and Platform.
- Optional (Pro): turn on Barcode box.
- Press Create cover page. A new page is added at the full wrap size.
- Design your cover on that page, then delete the magenta guide shapes before you export. Press Copy summary to copy the sizes for the publishing form.

FAQ
Are the numbers exact?
White and cream paper factors for Amazon KDP are the published per-page values. Hardcover wrap, IngramSpark margins and the colour paper factors are approximate, and the panel says so whenever one is used. Check them against the platform's own calculator.
Why does Resize add a new page?
Canva apps cannot change the size of an existing page, so Resize adds a new page at the new size and asks you to delete the old one. A background image is not copied; re-apply it.
What counts towards the monthly limit?
One cover written. A resize counts as one too. The unit is given back if Canva refuses to add the page.
Do the guides print?
No, if you delete them. They are magenta shapes with a label, so delete them before you export.
