Amazon KDP Paperback Rejection Errors & Fix Guide¶

Amazon KDP uses automated print validation to catch paperback geometry, cover, image, and PDF problems before production.

This section remains a supporting publishing cluster in this site. Its role here is to route you to the right KDP page type rather than to compete with every individual publishing query.

What This Section Covers¶

Use this section when you need to sort a KDP issue into the correct family before rebuilding files or resubmitting.

Start Here If¶

you need the main explanation of a KDP issue family
you already know the problem and need the more specific issue page
you want a pre-submission checklist rather than a broad explanation

Precheck vs. Guide vs. Issue Explanation¶

Guide pages explain a broader issue family and help you decide where the real problem belongs.
Issue pages focus on a specific rejection or warning state.
Precheck pages are best when you already know the issue family and need a submission-readiness workflow.

Common Issue Families¶

Bleed, Margins, and Gutter¶

Use this group when the problem is page geometry, trim edge coverage, or text safety zones.

Cover Template and Size Mismatch¶

Use this group when the cover PDF, spine width, or template dimensions do not match KDP's expected geometry.

Font Embedding, Formatting, and Low Resolution¶

Use this group when the rejection is mainly about PDF technical quality, fonts, or print image quality.

Rejected PDF and Technical Follow-Up¶

Use these pages when the file has already been rejected and you need a broader remediation path rather than only one issue explanation.

What to Check Next¶

Start with a guide page if you only know the issue family.
Start with an issue page if KDP named the rejection clearly.
Start with a precheck page if you already know the root family and want a clean resubmission workflow.
