Amazon KDP Formatting Checklist: What to Review Before You Upload

Overview

This guide gives you a practical, repeatable checklist for preparing files before you upload to KDP. It is not tied to one software tool or one genre. Instead, it focuses on the formatting decisions that tend to matter across fiction, nonfiction, ebooks, and paperbacks.

The most useful way to think about a KDP formatting guide is this: formatting is not decoration. It is the layer that controls reading comfort, navigation, and presentation. A manuscript can be fully edited and still feel unprofessional if the chapter headings are inconsistent, paragraph indents break from scene to scene, the table of contents does not work, or the print margins are off.

Before you upload, separate your review into three passes:

• Content pass: confirm that the manuscript is final enough to format.
• Layout pass: review headings, spacing, page breaks, front matter, back matter, images, and links.
• Export and preview pass: check the actual files you will upload and inspect them in preview tools and on real devices if possible.

This order matters. Formatting a book before the text is stable creates extra work. If you are still doing major revision, it may help to finish your editorial passes first. For that stage, related revision resources on Critique Lab include the Novel Revision Timeline, the Dialogue Editing Checklist, the Point of View Checklist, and the Story Pacing Checklist.

Once the text is stable, move through the checklist below.

Checklist by scenario

Use the scenario that fits your release. If you are publishing both ebook and paperback, complete both lists. Many upload issues happen because authors assume one clean file can serve every format without adjustment.

Ebook formatting checklist

• Use consistent paragraph styling. Apply one body style throughout. Avoid manual tabs and repeated spaces to create indents.
• Use page breaks before chapters. Do not create chapter starts by pressing Enter repeatedly.
• Keep headings consistent. Chapter titles, part titles, and subheadings should use a clear hierarchy.
• Build a working table of contents. Use proper heading styles so navigation works on e-readers.
• Review front matter. Title page, copyright page, dedication, epigraph, and table of contents should appear in a sensible order.
• Review back matter. Author note, also-by page, newsletter link, website, and review request should be current and intentional.
• Check hyperlinks. Website, mailing list, and internal links should work and be easy to tap.
• Limit forced styling. Fancy fonts, oversized spacing, and rigid layout choices often display poorly on smaller screens.
• Anchor images carefully. If your ebook includes images, test how they reflow and whether captions remain legible.
• Inspect scene breaks. Use a simple, repeatable visual marker such as a blank line or a centered ornament that survives reflow.
• Check special characters. Em dashes, ellipses, smart quotes, accented letters, and ornamental glyphs should display correctly.
• Remove tracked changes and comments. This sounds obvious, but hidden markup can survive longer than expected.
• Export a clean final file. Name it clearly with version control so you do not upload the wrong draft.

Paperback formatting checklist

• Confirm trim size first. Your page size affects margins, page count, and spine calculations. Choose it before final interior formatting.
• Set mirrored margins where appropriate. Print interiors usually need inside and outside margins that account for binding.
• Use consistent paragraph indents and spacing. Print exaggerates inconsistency. If one paragraph style is off, readers will see it.
• Keep chapter openers intentional. Decide how chapter starts will look and repeat the pattern throughout.
• Check page breaks. Avoid accidental blank pages, widows, or orphaned lines where possible.
• Review running heads and page numbers. If you use them, keep them consistent and do not place them where chapter opening pages should remain clean.
• Inspect left and right pages. A print PDF can look balanced in one-page view and awkward in two-page spread view.
• Make sure images are print-ready. Low-quality images that seem acceptable on screen may look weak in print.
• Check black-and-white elements. Grayscale charts, ornaments, or illustrations should remain readable without color.
• Review front and back matter in print order. Print conventions can differ slightly from ebook expectations.
• Proof page count effects. A late correction can shift pagination and create new layout problems farther down the book.
• Export the final print PDF carefully. Inspect the actual PDF, not just the document in your drafting software.

Checklist for books with both ebook and paperback editions

• Do not assume one file suits both editions. Reflowable ebooks and fixed print interiors need different review standards.
• Match the metadata where it should match. Title, subtitle, author name, and series information should be consistent across files and listings.
• Tailor the back matter. A clickable link works well in an ebook, but a paperback may need a short, memorable URL or QR code if appropriate.
• Check edition language. If this is a revised edition, make sure the revision note is consistent in all versions.
• Review sample pages. The opening pages often determine reader confidence. Make them especially clean.

What to double-check

This section covers the items most likely to create trouble even after a manuscript appears finished. Think of these as your final quality-control checks in an ebook formatting checklist or paperback formatting KDP review.

1. Front matter order

Front matter often gets copied from an older project and forgotten. Double-check the title page, copyright page, dedication, epigraph, table of contents, foreword, preface, and introduction. Make sure each element belongs in this book and appears in the order you intend.

2. Chapter heading consistency

Scan the full manuscript just for chapter starts. Are the fonts, spacing, alignment, numbering style, and ornament choices consistent? If Chapter 7 is slightly different from the others, it usually means manual formatting has crept in.

3. Paragraph behavior after italics, scene breaks, and block quotes

Formatting glitches often appear after special elements. Check whether the first paragraph after a chapter heading is intentionally unindented, whether paragraphs after scene breaks follow the same rule, and whether block quotes return to the correct body style afterward.

4. Navigation and links

For ebooks, test the table of contents and every live hyperlink. A broken newsletter link or author website link wastes one of the few moments when a reader is most ready to follow you elsewhere. If author platform growth matters to you, this is not a minor detail.

5. Device and preview behavior

A file that looks fine in your editor may behave differently in preview. Review chapter starts, image placement, ornamental breaks, and long paragraphs in the preview environment. If possible, also look at the file on at least one phone-sized screen and one larger screen.

6. Print readability

For paperbacks, zoom out and inspect page texture. Are there dense pages with too little white space? Are headings crowding the body text? Do page numbers and running heads feel balanced rather than cramped? Readability matters as much as correctness. If you are refining sentence flow before this stage, the guides on readability score for writers and text-to-speech for proofreading can help you catch issues before layout review.

7. Final proofreading on the formatted file

Always proof the formatted version, not only the manuscript version. New errors can appear during conversion: dropped line spaces, duplicated headings, broken italics, missing scene breaks, or inconsistent paragraph indents. A grammar tool may help with a last pass, but formatted proofing still needs human review. For related comparisons, see Best Grammar Checker for Fiction Writers and Best AI Editing Tools for Writers.

8. File naming and version control

One of the simplest preventable mistakes is uploading the wrong file. Use a clear naming structure that includes edition, format, and date or version number. Keep a separate archive folder for superseded files so the final upload folder stays clean.

Common mistakes

These are the problems that repeatedly cause unnecessary delay or a less polished reading experience. If you are wondering what to review before uploading to KDP, start by trying to eliminate these.

• Formatting before the text is stable. Late rewrites create cascading layout problems.
• Using spaces or tabs for visual alignment. This is fragile and tends to break during conversion.
• Mixing manual formatting with styles. The document may look consistent until export reveals hidden differences.
• Skipping the preview stage. A clean source document is not the same as a clean rendered book.
• Forgetting the back matter. Old links, outdated calls to action, or missing author pages are common.
• Ignoring chapter-opening pages in print. Headers, page numbers, and spacing often need special handling.
• Using low-resolution images. What passes in a draft may not hold up in a finished edition.
• Overdesigning the ebook. Reflowable files usually reward simplicity and consistency.
• Failing to test navigation. A nonfunctional table of contents makes a book feel unfinished.
• Uploading without a final read-through. Even one focused pass through the formatted file can catch visible errors.

A useful rule: if a formatting choice depends on manual adjustment in many places, it is more likely to break later. Favor repeatable styles over one-off fixes.

When to revisit

The best checklist is one you return to, not one you use once and forget. Revisit this KDP formatting guide whenever one of these conditions changes:

• You switch writing or formatting tools. New software can alter exports, heading behavior, and image handling.
• You publish in a new format. Moving from ebook-only to paperback requires a different review mindset.
• You change trim size or interior design. Even a small print design change can affect page count and layout balance.
• You release a revised edition. New front matter, back matter, and pagination should be reviewed from scratch.
• You update your author platform. If your website, newsletter, or back matter links change, update them before the next upload.
• You are preparing for a launch window. Before a seasonal release or promotion cycle, recheck the files so you are not fixing preventable issues under time pressure.

For a practical workflow, create your own version of this checklist in a document or project manager and divide it into four boxes: before formatting, before export, after upload preview, and after proof copy review. That keeps the process calm and repeatable.

If you are refining the wider publishing workflow around your book, it may also help to review complementary systems and tools, including Writing Productivity Tools Compared and Best Free Writing Tools for Authors.

Before your next upload, do this in order:

1. Freeze the manuscript text.
2. Choose the target format and edition.
3. Format using styles, not visual hacks.
4. Export the final file with clear version naming.
5. Review in preview mode and on a real device if possible.
6. Proof the formatted file one last time.
7. Only then upload.

That sequence will not guarantee a perfect release, but it will remove many of the most common formatting problems before they become public ones. For indie authors, that is often the difference between a stressful upload day and a controlled one.
