Summary
The KDP Cover Calculator works out the full wrap dimensions of a print cover, including the spine, from your trim size, page count and print options, and lets you download a PDF and PNG template to use as a guide layer in your design software. It covers paperback and hardcover only; eBook covers do not need it. It does not design the cover for you, and the template is a guide, not a finished file.
Best for
- Getting exact spine and full-wrap dimensions before designing a print cover
Pros
- Free, no sign-in needed, and the numbers come from KDP itself
- Template downloads as both PDF and PNG
Cons
- Spine width changes with page count, so the template must be regenerated if the interior changes
- Gives dimensions only; the artwork is up to you
