kdpcover.pro (“the service”) is a free, client-side calculator for Amazon KDP cover dimensions. It is independent and not affiliated with Amazon, Kindle Direct Publishing, or any KDP-related trademark.

2. Accuracy

We make every reasonable effort to keep our spine multipliers and formulas current with KDP’s published specifications. However, KDP can change requirements at any time. Always verify your final cover against KDP’s official template generator before submission. We are not liable for rejected uploads, printing errors, or any other consequence of relying on the values shown here.

3. Acceptable use

You may use the service for any lawful purpose, including commercial design work. You may embed the iframe widget on your site provided you do not remove the “Powered by kdpcover.pro” attribution.

4. No warranties

The service is provided “as is”, without warranties of any kind, express or implied.

5. Changes

We may update these terms at any time. Continued use after a change constitutes acceptance.
