How to Format an Ebook for Amazon KDP (US Author Checklist)

If you are working out how to format an ebook for Amazon KDP, the job comes down to structure: consistent styles, real chapter breaks, clean images and a file KDP converts without errors. This ebook formatting checklist covers Word styles, Kindle Create, Previewer checks, common upload failures, and when to hire help. Categories, pricing and KDP Select are covered in our KDP publishing checklist for first-time authors. Amazon's help pages remain the final word on platform rules.

Quick answer

Takeaways

The short version:

Kindle ebooks are usually reflowable: readers change the font size and the lines rewrap. You are formatting structure (styles, chapters, images), not a fixed page.
Start in Word with consistent paragraph styles and Heading 1 chapter titles, which is what Amazon's eBook Manuscript Formatting Guide is built around.
Kindle Create turns a clean Word file into a KPF to upload. The KCB project file is not what goes to KDP.
Most upload problems come from inconsistent styles, hard returns, the wrong file type or skipping the Previewer.
A simple text book is usually fine to do yourself. Complex layouts, heavy tables or repeated upload failures are signs to hire help.

Formatting is not the same as publishing on KDP

These are two separate jobs. Formatting means producing an ebook file that converts and reads well. Publishing setup means the title details, categories, description, pricing, territories and going live.

This guide covers formatting only. Once your Previewer checks pass, finish setup with the publishing checklist. If you are still deciding between a short lead magnet and a longer book, that choice comes earlier; see lead magnet ebook vs authority book.

One ordering rule matters: structural editing and copy cleanup happen before anyone picks a Kindle theme. A polished theme on a broken structure wastes time and money. To work out which edit you need, see developmental editing vs copyediting.

Step 1: Prep a clean Word manuscript

Amazon's guide assumes Microsoft Word, but the same approach works for Google Docs exports. Styles beat manual formatting every time.

Work through these in order:

Adjust the Normal style so body text is consistent everywhere. Amazon's guide suggests a first-line indent of about 0.2 inches (5 mm), Before and After spacing of 0 pt, and single line spacing as a safe starting point.
Apply Heading 1 to every real chapter title. Faking chapter titles with bold and a larger font breaks automatic tables of contents.
Insert a real page break before each chapter (Insert, then Page Break) instead of pressing Enter repeatedly.
Build a linked table of contents from the Heading 1 styles, or plan to create one in Kindle Create.
Add front matter: a title page with your name, plus copyright and a dedication if you want them.
Add back matter: About the Author, and optionally resources or an "also by" page.

Ebook and print need separate files

If you have already published a paperback, the ebook still follows ebook rules. Print has fixed pages, gutters, headers and page numbers. Kindle mostly does not, so uploading a print layout will not give you a good ebook.

What to leave out of your ebook manuscript file

Several things that look fine in Word cause problems on a Kindle. Remove or fix these before you upload:

The cover image on page one. You upload the cover separately during title setup, and Amazon adds it to the book.
Page numbers, headers and footers. They mean nothing when the reader changes the font size and every page shifts.
Tracked changes and comments. Accept or reject them all and turn Track Changes off.
Text boxes. Convert the content to normal text, or to an image if it is a chart or table that must keep its layout.
Hard returns at the end of every line. Once Kindle reflows the text, these break paragraphs into fragments.
Decorative drop caps. Amazon often suggests styling chapter openers in Kindle Create instead.
Stray fonts and spacing pasted in from emails and web pages.

Images in your ebook

Keep images that help the reader, at screen quality, placed in line with the text where they belong. Amazon links a separate image guide from its manuscript formatting page, which is worth reading if your book is photo heavy.

Step 2: Kindle Create path (Word to KPF)

Kindle Create is Amazon's free desktop tool. Following Amazon's tutorial, the process looks like this:

Install it and start a new project from your cleaned Word file.
Kindle Create suggests where your chapters begin. Accept only the correct ones, and fix false splits before styling anything.
Work through Front Matter, Body and Back Matter, adding the title page, copyright, dedication and an optional table of contents with the built-in tools.
Style your chapter openers and, if you like, choose a theme. Amazon's tutorial lists options such as Modern, Classic, Cosmos and Amour.
Add images and links where they help readers.
Use Preview to check tablet, e-reader and phone views.
Export a KPF file for KDP.

Upload the KPF, not the project file

Kindle Create's working project is usually a KCB file plus some resource files. Uploading that instead of the export is a very common mistake. Upload the exported KPF, or a clean DOC or DOCX if you skipped Kindle Create.

Kindle Create is optional. Amazon still accepts DOC and DOCX, so use Create only if it saves you work.

Step 3: Previewer checklist before you hit Publish

Kindle Previewer catches problems you will not see in Word. Check for each of these:

A chapter starting halfway down a page because a page break is missing
Table of contents links that go to the wrong chapter or nowhere
Images that fill the whole phone screen or are too small to read
Links showing as raw URLs instead of readable text
Extra gaps between paragraphs from double returns
Long front matter that pushes chapter one deep into the free sample

Check every device type

Switch between tablet, e-reader and phone views, because a layout that looks fine on a tablet can feel cramped on a phone. After uploading to KDP, run the Online Previewer one more time before you publish.

Common upload and quality fails (and how to fix them)

These problems come up repeatedly in DIY guides, Amazon's error checklist and author forums:

Inconsistent chapter styles. Some chapters use Heading 1 and others are just bold, so navigation breaks. Fix: give every chapter title the same Heading 1 style.
Wrong file type. Uploading the KCB project instead of the KPF, or a print PDF meant for the paperback. Fix: upload the exported KPF or a clean DOCX.
Tab indents. Tabs often do not convert as expected. Fix: build the indent into the paragraph style.
Tracked changes or comments left in the file. Fix: accept or reject all and remove comments.
The cover pasted inside the book. Fix: delete it and upload the cover separately.
Columns, text boxes and complex tables that fall apart on reflow. Fix: simplify them, convert the worst section to an image as a last resort, or bring in a formatter.
Large or blurry images. Fix: compress carefully and check that charts are still readable on a phone.

If KDP rejects your file

A request to fix and resubmit is a normal debugging round. It says nothing about the quality of your writing. Fix the specific issue KDP names, preview again and resubmit.

DIY vs hire: when to stop wrestling the file

Formatting it yourself works well when the book is mostly flowing prose (a novel, memoir or simple how-to), when you have a solid half day for styles and Previewer fixes, and when it is a single simple ebook.

Consider a formatter, or a studio package that includes production, when any of these apply:

The book is a workbook with checklists, sidebars or tables on most pages
You have failed upload twice and cannot find the cause
Your time is worth more than another weekend of fixing indents
You want matching ebook and print files without maintaining two fragile setups

What professional formatting costs

These are public market figures, not our pricing. Chapter's 2026 formatting roundup puts professional company work often in the $200 to $800+ range, freelance jobs at roughly $50 to $500, and DIY tools from free (Reedsy Studio) up to one-time software fees.

The Editorial Freelancers Association rate chart lists survey median ranges for formatting and self-publishing help that you can use for planning. Those rates come from a member survey; they are not required prices.

For print interiors (trim size, orphans and widows, facing pages), Reedsy's explainer on typesetting is useful. Print typesetting and Kindle reflow are related but not the same. A designer writing on Jane Friedman's blog put specialist print interiors at around $2.00 to $3.50 per page; that is a print figure, and ebooks do not automatically cost the same.

If your manuscript came from a ghostwriting project, ask what file you receive at the end: an edited Word document or something ready to upload. Packages differ; see what is included in a professional ebook writing package.

A simple US-author formatting sequence you can copy

Spread the work over about a week so each step gets proper attention:

Day 1: lock the content. No more moving chapters.
Day 2: clean up Word styles, apply Heading 1 to every chapter, add page breaks, and remove the cover, headers, footers and tracked changes.
Day 3: import into Kindle Create, or keep a clean DOCX instead.
Day 4: preview on phone, e-reader and tablet and fix what you find.
Day 5: export the KPF, upload to KDP, run the Online Previewer again, fix any remaining issues and resubmit.
After that: move on to the publishing checklist.

Plan formatting into your timeline

If editing, a cover and a launch are still ahead, keep those weeks visible on a write and publish timeline so formatting does not take over the week you needed for proofreading.

FAQ

How do I format an ebook for Amazon KDP?

Start with a tidy Word file that uses Heading styles and page breaks between chapters, and remove the cover, headers, footers and tracked changes. Then upload a clean DOCX or build a KPF in Kindle Create. Check the result in Previewer on phone and tablet, fix any problems with the table of contents, images or spacing, and finish the KDP upload.

What file format does Amazon KDP prefer for ebooks?

KDP accepts EPUB, DOCX and Kindle Create's KPF. A validated EPUB tends to behave predictably across devices and is easy to check before upload, which is why many professional formatters deliver one. A clean DOCX or KPF works well for most text-based books.

Do I need Kindle Create to publish a Kindle ebook?

No. Amazon accepts a clean DOC or DOCX, along with other supported formats. Kindle Create is useful for styling chapters and exporting a KPF, so use it if it saves you work, and skip it if your Word file already previews well.

Do I need special software to format an ebook for KDP?

No. Tidy Word styles plus the free Kindle Create and Kindle Previewer will handle a typical nonfiction book. Paid tools such as Vellum or Atticus are worth considering if you plan to publish several books or want print and ebook from one file.

Should I format ebook and paperback the same way?

No. An ebook usually reflows, while a paperback has fixed margins, gutters and page numbers. Plan separate files, or a workflow that exports both carefully, because a print PDF will not make a good Kindle book.

Why does my TOC break on Kindle?

Usually the chapter titles were styled by hand instead of with one Heading style, or the table of contents was typed as plain text without working links. Rebuild it from Heading 1, or use Kindle Create's table of contents tools.

Why does my ebook look different on a phone than on a Kindle?

Readers choose their own font size, and each device wraps lines differently. A pixel-perfect page is not possible in a reflowable ebook, so focus on structure and test on phone, tablet and e-reader in Previewer.

Can I fix formatting after I publish?

Yes. You can upload an updated manuscript in KDP at any time. Preview it carefully first, because readers notice broken indents and missing chapter breaks quickly.

How much does professional ebook formatting cost?

Freelance formatting on its own often falls somewhere between about $50 and $500, depending on length and complexity, with company work running higher. In a full writing package, formatting is normally included alongside editing and the cover.

Is hiring a formatter worth it for a short ebook?

Sometimes. If the book is short, text only and you are comfortable in Word, doing it yourself makes sense. If it is a lead magnet that needs a polished brand look, or you are stuck in repeated rejections, one professional pass can save you a lot of time.
