Last updated: 2026-04-09
bleed missing is one of the most common kdp paperback validation failures. Use the sections below to verify the issue and correct the file before re-uploading.
KDP Bleed Missing Error? Fix Your PDF Before Upload (Exact Bleed Settings)
Yes - this is a real file problem.
If you're seeing this error in KDP upload or preview, this fix will resolve it.
The root cause is simple: your PDF does not include real bleed, or your artwork stops at trim instead of extending past trim.
Fix this now
- Set bleed to
0.125 in. - Extend every edge-touching image or background beyond trim.
- Export a fresh PDF with bleed included, then upload that new file.
Use this tool first: Bleed Calculator
Exact settings
- Interior bleed math: width = trim width +
0.125 in - Interior bleed math: height = trim height +
0.25 in - Cover bleed:
0.125 inon all outer sides - Do not upload a trim-size PDF if the book is set to bleed in KDP
Fast check before re-upload
- If PDF size equals trim size: bleed is missing in export
- If PDF size is larger but white edge still appears: artwork does not extend into bleed
- If only some pages fail: those pages stop at trim
When this error appears
- background reaches the edge in your layout
- exported PDF does not include bleed
- KDP bleed setting and uploaded PDF geometry do not match

Error Meaning
This KDP validation failure means your PDF does not match one or more required print geometry or metadata constraints for the selected paperback setup.
How KDP Validator Detects It
KDP runs automated preflight checks on PDF geometry, font embedding, and raster quality before your file moves to manual review.
In practice, KDP compares trim settings, bleed flags, and spine calculations against the uploaded files and expected print profile. If any numeric tolerance is out of range, the job is rejected even when the preview looks acceptable.
Numeric Verification
- Trim size (inches)
- Spine width formula
- Bleed tolerance (0.125 in)
| Parameter | Required Value | Common Mistake |
|---|---|---|
| Bleed | 0.125 in | 0.1 in or missing |
| Trim | Exact spec match | Scaled PDF |
Fix by Software
Affinity Publisher
Exact export preset and bleed settings.
InDesign
Document setup and PDF/X export profile.
Canva
Canvas size verification and crop mark handling.
LaTeX
geometry package settings and trimbox checks.
Common Edge Cases
Page-count changes without regenerating the cover, hidden off-trim objects, and template versions from a different trim profile are frequent causes of repeat rejection.

Related Questions
Why can KDP Bleed Missing Error? Fix Your PDF Before Upload (Exact Bleed Settings) pass visual checks but fail Amazon KDP validation?
Visual review is not authoritative. Platform validation checks geometry, resources, and metadata numerically, and small mismatches trigger rejection.
Should I patch the exported PDF directly or re-export from source?
For repeatable recovery, re-export from source with a locked print preset. Direct patching can introduce additional drift in page boxes and embedded resources.
What is the fastest workflow to prevent repeat rejection loops?
Use deterministic order: verify geometry first, then fonts/images/transparency, then platform metadata and template version before upload.
How do I verify trim and bleed are aligned with upload settings?
Confirm selected trim mode first, then check final PDF dimensions and page boxes match that exact mode without export scaling.
What causes white-edge defects despite correct-looking layout files?
Edge artwork usually stops at trim instead of extending into bleed, so normal manufacturing variance exposes unprinted paper.
