BoundHive KDP Cover Size Calculator
A free browser calculator for independent authors and paperback cover designers. Enter trim size, ink and paper type, and the final interior page count to calculate the full-wrap cover width and height, spine width, panel positions and barcode safe area for a supported KDP paperback configuration. No account is required. Results show a rules version and links to Amazon KDP source guidance. Recalculate when the final page count changes, and check the finished file against current KDP requirements. The calculator does not inspect artwork, image resolution or hardcover wraps. BoundHive is independent of Amazon. Submitted by a BoundHive representative; this listing covers the standalone free calculator.
