Word Export PDF for KDP

This page is the primary hub for Word-based KDP formatting failures. Use it to route from a visible symptom to the exact Word problem page, the PDF export failure, or the KDP Preview failure that matches the file state.

What Goes Wrong in Word Before Export

Word failures usually start before the PDF exists. The source document carries unstable page geometry, mirrored-margin logic, section-level overrides, or object widths that already make the export unsafe.

Layout Issues

Use these pages when the manuscript layout is unstable before export:

Margin & Mirror Margin

Use these pages when inside/outside spacing, gutter behavior, or mirrored layout logic is wrong:

Page Numbers / Headers

Use these pages when page furniture is drifting toward trim or binding:

Section Breaks

Use this page when the document changes behavior mid-file because page setup is no longer consistent:

Word Section Break Causing Layout Errors

Tables / Overflow

Use this page when tables exceed the usable text area and push the file into margin or trim failures:

Word Tables Overflowing Page Margins

What Breaks During PDF Export

Word can look stable while the exported PDF becomes structurally wrong. This is where trim drift, hidden scaling, missing font data, and image degradation show up.

Export Geometry Failures

Use these pages when the exported PDF no longer matches the intended physical page:

Font / Embedding

Use these pages when Word export creates missing, substituted, or incomplete font resources:

Image Resolution

Use these pages when Word export preserves layout but degrades print image quality:

What Fails in KDP Preview

When Word and the PDF export path are unstable, KDP Preview usually reports the downstream symptom rather than the original Word cause.

Use these pages when the failure only becomes obvious after upload:

Mapping Symptoms to Exact Problem Pages

Use this section as the routing layer.

The Word file looks wrong before export

margins alternate incorrectly: Word Mirror Margins Not Working for KDP Paperback
gutter looks wrong on facing pages: Margin Too Small
page numbers sit too close to the spine: Word Page Numbers Too Close to the Binding
running headers shift or reset: Word Running Headers Misaligned in KDP Paperback
layout changes after one chapter or section: Word Section Break Causing Layout Errors
paragraph spacing changes pagination unpredictably: Word Paragraph Spacing Causing Layout Problems
tables run beyond the page width: Word Tables Overflowing Page Margins

The PDF exports at the wrong size or wrong structure

Word export changes trim or scale: Word PDF Export Scaling Error for KDP
the narrower issue is specifically Word-to-PDF scaling drift: Word PDF Export Scaling Issues for KDP
the exported PDF trim does not match KDP settings: Word Trim Size Mismatch with KDP Settings
the broader export pipeline is failing beyond Word-only cases: PDF Export Scaling Error

The PDF opens, but resources are unstable

fonts substitute or are not embedded: Word PDF Font Embedding Issues for KDP
images become soft or compressed: Word Images Too Low Resolution for KDP

The upload only fails in KDP Preview

KDP reports scaling after upload: KDP Preview Scaling Detected
preview layout does not match the local PDF: KDP Preview Layout Different
preview changes the typeface: KDP Preview Font Substitution
interior shifts after upload: KDP Preview Interior Shifted

Flow: Word → PDF → KDP Preview → Fix Path

Word Find the source-document failure first: Word Mirror Margins Not Working for KDP Paperback, Margin Too Small, Word Section Break Causing Layout Errors, Word Tables Overflowing Page Margins.
PDF If the source looks stable but the exported file is wrong, move to: Word PDF Export Scaling Error for KDP, Word Trim Size Mismatch with KDP Settings, Word PDF Font Embedding Issues for KDP, Word Images Too Low Resolution for KDP.
KDP Preview If the local PDF looks acceptable but KDP changes the behavior, move to: KDP Preview Scaling Detected, KDP Preview Layout Different, KDP Preview Font Substitution.
Fix Path If the failure is still ambiguous, branch into the broader system pages: PDF Export Scaling Error, Bleed & Trim System Failures, Print PDF Export System.
