KDP error guide

Prepare one continuous full-wrap cover page

Verify that the cover PDF contains one continuous full-wrap page.

Technically reviewed · September 1, 2026

What this issue means

Front and back covers submitted as separate pages cannot represent the expected back-spine-front geometry. The checker reports page count before evaluating full-wrap size.

What BookPreflight checks

  • Cover PDF page count
  • Orientation and full-wrap dimensions
  • Back, spine and front placement on the single page

How to correct the source file

  1. 1

    Create one artboard at the complete template size.

  2. 2

    Place back cover, spine and front cover from left to right as required.

  3. 3

    Export only that artboard as a one-page PDF.

Verify the exported PDF, not the preset name

Keep the editable source and original PDF. Export a new file, run the complete scan again and review every remaining finding. A repair is only labelled safe after loss checks and a full deterministic post-flight.
