Formatting That Works (Kindle + Print)

Formatting is invisible when done right and a sales-killer when done wrong. Aim for clean, readable, and metadata-correct files that sail through ingestion on Kindle and print-on-demand.

File Prep Basics

Trim + margins: Pick your trim (e.g., 5.5"×8.5") and set margins/bleed to printer specs.
Styles, not tabs: Use paragraph styles and spacing; never tab-indent manually.
Images: 300 dpi for print, compressed for ebook; anchor images properly.
Front/back matter: TOC, copyright, acknowledgments, about the author, CTA.

Preflight Checklist Before Export

Style consistency: Body, heading, quote, and caption styles are applied globally (no one-off manual overrides).
Scene-break formatting: Every scene break uses the same glyph/spacing pattern and survives device reflow.
Page-break handling: Chapter starts force breaks; avoid random hard page breaks inside normal paragraphs.
Linked TOC + heading hierarchy: TOC links resolve correctly and heading levels (H1/H2/H3) are structured in order.

Kindle Pitfalls to Avoid

Common Failures

Broken TOC links (verify NCX/HTML TOC both work)
Weird line breaks from copy-pasted tabs
Images that overflow on small screens
Footnotes/endnotes not hyperlinked correctly

Always sideload to a real device + Kindle Previewer. Don’t trust browser-only previews.

Kindle File QA Flow

Export format: Generate your source export (DOCX/EPUB/KPF) from clean styles, then archive that exact build.
Kindle Previewer checks: Validate navigation, image scaling, font resizing, and any warnings in Previewer before upload.
Device checks: Sideload to at least one e-ink Kindle and one app/device class (tablet or phone) for real-world readability.
Post-upload validation: After KDP processing, review the online preview plus the live sample to catch conversion-side regressions.

Print-on-Demand Checks

Bleed settings correct; no live text within the trim safety zone.
Barcode area clear; black ink set to rich black where appropriate.
Check widows/orphans after pagination changes.
Order a proof copy; fix spacing/kerning issues you only see in print.

Print Wrap Math and Spine Dependencies

Your full-wrap print cover width depends on trim size + page count + spine width + bleed. Spine width is driven by final page count and paper type (cream, white, or color stock each has different caliper), so even small interior edits can shift the spine and misalign your wrap.

Trim changes ripple into everything: cover template dimensions, safe zones, and back-cover text fit. Lock your interior first, then pull the latest printer template using final page count and selected paper to avoid rework.

Common Ingestion Rejection Reasons

Ebook (Kindle/EPUB)

Malformed TOC/nav structure or broken internal links.
Unsupported CSS/HTML causing rendering failures.
Low-resolution, missing, or improperly embedded images/fonts.
Metadata mismatches (title/author/series inconsistency).

POD (Paperback/Hardcover)

Bleed/safe-zone violations or text outside printable area.
Spine text misalignment from incorrect page-count assumptions.
Interior PDFs with font embedding/transparency issues.
Cover barcode/contrast/trim dimension mismatches.

Metadata Inside the File

Embed correct title, author, series, and keywords in the file metadata. Inconsistent internal metadata can confuse ingestion systems and hurt searchability.

When to DIY vs. Hire

If this is book one and you’re comfortable with Vellum/Atticus/Word templates, DIY is fine. If you have complex layouts (tables, images, workbooks) or zero time, hire a formatter. Get one sample chapter formatted before committing.

Quick Tool Comparison

Option	Best for layout complexity	Time cost
Word templates	Low complexity (straight text chapters)	Medium to high (manual cleanup likely)
Vellum	Low to medium complexity with polished defaults	Low (fast once styles are clean)
Atticus	Low to medium complexity, cross-platform workflow	Low to medium (depends on browser/editor flow)
Pro formatter	Medium to high complexity (tables, images, workbook layouts)	Low author time, higher coordination/review time
