Amazon Kindle Direct Publishing accepts ebooks, paperbacks and hardcovers, and it checks every file against rules for size, margins, fonts, images and covers before a book can go live. Understanding those rules before you format saves the time that authors lose to upload errors. This KDP formatting guide explains what each format needs, how the pieces fit together and how to avoid the errors that we see most often, in a form that works for beginners and for experienced authors who want a checklist.

KDP formatting guide: ebook, paperback and hardcover interiors and covers
For ebooks, KDP accepts EPUB, and Word, KPF and other formats can be converted, though EPUB gives the most control. The ebook needs a linked contents page, clean styles, images at suitable resolution and a cover that is about 2,560 pixels high and 1,600 pixels wide. For paperbacks, KDP wants a PDF of the interior with fonts embedded, margins that match the page count and bleed if images touch the edge, plus a separate cover PDF that includes back, spine and front sized from the page count and paper type. Hardcovers add a case laminate cover and a more limited range of trim sizes.
Each section of this guide ends with what to check. The guide covers trim sizes, margins by page count, bleed, fonts, images, cover sizing, ISBN and barcode placement, the KDP previewer and the most common error messages. It also explains when it makes sense to hand the formatting over to a professional. Our KDP-ready interior and cover services deliver files that pass the preview first time, and we can upload them to your account.
This KDP formatting guide is also a KDP formatting guide PDF you can print, a KDP ebook formatting guide, a KDP cover formatting guide and an Amazon KDP formatting guide in one. It covers a KDP ebook manuscript formatting guide for Word files, a KDP formatting guide for ebooks, a KDP formatting guide for beginners and a KDP formatting guide step by step. It is current as a KDP formatting guide 2026, with a KDP formatting guide trim size and margins section and a KDP formatting guide for hardcover.
Why KDP formatting rules matter
KDP checks every file automatically before it goes live
The previewer measures margins, fonts, image resolution, trim size and bleed the moment you upload. A file that fails is not published, and each failed round costs a day or more, which matters most when a launch date or a pre-order deadline is fixed.
Print rules depend on your page count
The inside margin that is acceptable for a 100-page paperback is too narrow for a 500-page one, and the spine width changes the cover size. Formatting to the page count at the start prevents the most common KDP rejections and resizing rounds later.
Your files are your product on Amazon
Readers cannot see your manuscript before they buy, but they can see the Look Inside preview, the cover thumbnail and the first pages. Clean formatting makes that preview convincing, and sloppy formatting loses sales and attracts reviews that mention it.
From manuscript to a file that KDP accepts
A KDP interior formatting guide begins with the choice of trim size, since KDP supports a set of sizes and the gutter margin depends on the page count. The interior is uploaded as a PDF for paperbacks and hardcovers, with fonts embedded, and as an EPUB or a supported file for ebooks.
KDP ebook manuscript formatting needs a clean structure with styles, a linked table of contents and images that scale, and it is tested in Kindle Previewer on phone, tablet and eReader views. KDP formatting guide for paperback and hardcover books adds the cover, which is a single wrap file sized to the trim and the spine.
The KDP formatting guide Word template can be a helpful start, but a template does not know your book, so we build files by hand. KDP rules and sizes change from time to time, so this guide says where to check KDP's current help pages, and our formatting follows the instructions in force on the day that we prepare your files.

Build my priceKDP formatting step by step
Choose your formats
Decide whether you want an ebook, a paperback, a hardcover or all three, because each format has its own file and specification and some choices affect others.
Pick the trim size and paper
Select a supported trim size and paper type, which determine your page count and spine width and affect printing cost and royalties.
Format the interior
Set margins from the page count, embed fonts, place images at 300 dpi and generate the contents, then export the PDF or EPUB for each format.
Build the cover from the page count
Once the interior is final, generate the cover template for the exact page count and paper and place the artwork inside it with bleed.
Preview and proof
Upload to KDP, read the online previewer, fix every warning and order a printed proof to check the physical result before you publish.
Publish and recheck
Approve the proof, publish and view the live listing and Look Inside preview, correcting anything that looks different from what you expected.

KDP Formatting Guide compared with the alternatives
The standards we apply to KDP files
Tested against the previewer
We run files through the KDP previewer before delivery and fix every warning, so that you do not discover margin or bleed problems after you have uploaded.
Built from the published rules
Margins, bleed, trim and image requirements come from the current KDP specifications and not from habit, and we recheck them when the platform updates its guidance.
Proofed on paper where it matters
We recommend and review a printed proof for any print book, because physical checks catch comfort and colour problems that no previewer can show.
The KDP formatting checklist
Every item below is verified on your KDP formatting walkthrough before it leaves our desk.
- Trim sizeA supported trim size is chosen and used consistently across every page of the interior and in the cover template.
- MarginsThe inside margin matches the page count and every outside margin is at least the KDP minimum for that size.
- BleedPresent only where images reach the page edge, at 0.125 inch on the outside edges, and absent everywhere else.
- FontsEvery font is embedded in the PDF, which is confirmed in the document properties before export.
- ImagesEvery image is at least 300 dpi at its printed size, with no enlarged low-resolution files.
- CoverBuilt from the final page count and paper type, with the spine width recalculated after the last edit.
- Barcode areaA clear space on the back cover for the barcode that KDP places, with no text or artwork behind it.
- EPUBA valid file with a linked contents page, a cover and complete metadata, tested in the Kindle previewer.
- ProofA printed proof ordered, read and approved before the book is published to readers.
How to think about KDP files
Read the rules once, carefully
Most KDP errors come from guessing at margins, bleed and cover size. Reading the specifications before you format saves far more time than it costs.
Make decisions in the right order
Choose trim and paper first, finish the interior second and build the cover last, because each step depends on the one before it.
Treat the proof as part of the process
A printed copy is the only way to see the real result, and ordering one is cheap compared with correcting a published book.
