Overview

KDP formatting guide: ebook, paperback and hardcover interiors and covers

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.

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 it matters

Why KDP formatting rules matter

01

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.

02

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.

03

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.

What is included

What KDP needs for each part of your book

One price covers the whole KDP formatting walkthrough job, and nothing essential to a KDP formatting walkthrough is held back for an upsell later.

The ebook interior

A reflowable EPUB with a linked contents page, styled headings, properly sized images and complete metadata, validated and checked in the Kindle previewer on phone, tablet and e-reader settings before it is uploaded to the dashboard.

The paperback interior

A PDF at your chosen trim size, with an inside margin set by page count, fonts embedded, images at 300 dpi and no content in the bleed area, so that the printed book reads comfortably and nothing is lost in the binding.

The paperback cover

A single PDF containing back, spine and front, sized from your final page count and paper type, with clear space for the barcode that KDP adds, and bleed on all outside edges so that trimming never leaves a white line.

The hardcover interior and case

A PDF at a trim size that KDP supports for hardcovers, and a case laminate cover with the correct wrap-around dimensions, including the hinge allowance, which differs from the paperback calculation and catches many authors out.

The ebook cover

A JPG or TIFF of about 2,560 by 1,600 pixels in portrait orientation, with a title that stays legible as a thumbnail on a phone, because the thumbnail is what most readers see when they decide whether to click.

The listing

Title, subtitle, series, description, categories, keywords, price and territories entered carefully, since metadata errors are hard to correct after launch and decide whether the right readers are shown your book at all.

KDP interior formatting guide

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.

  • Trim size, margins and gutter explained

Choose the right build

The first decision in any KDP formatting walkthrough

Ebook formatting for KDP

A clean EPUB or a converted file, validated and previewed in the Kindle previewer. It suits any text-led book.

Print formatting for KDP

A paperback or hardcover PDF and a matching cover, proofed on paper. It suits any book that you want to sell in print.

What we fix first

KDP formatting errors and how to fix them

Margins that are too small for the page count

KDP requires an inside margin that rises with page count, and text too close to the gutter disappears into the binding. Measure your page count first, then set the inside margin to the required minimum or more.

Images that print blurry

A picture that looks sharp on screen at 72 dpi prints soft at 300 dpi. Use images at least 300 dpi at the size they print, or place them smaller, and avoid enlarging small files inside the layout program.

A cover that does not match the final page count

Spine width depends on page count and paper, so a cover sized before the last edit may no longer fit. Generate the cover template only after the interior is final and the page count is fixed.

Fonts that are not embedded

A PDF with missing fonts can substitute them at upload, changing line breaks and page count. Export with fonts embedded, and check the font list in the PDF properties before you upload the file.

Bleed set wrongly

Images that reach the page edge need 0.125 inch of bleed, and images that do not should have none. Confusing the two causes warnings, so decide which pages have full-bleed art and set the document accordingly.

An ebook that fails the Kindle previewer

Common faults are a broken contents link, oversized images and styles that the device ignores. Validate the EPUB, test it in the previewer and fix every warning before you publish.

Specification

KDP formatting specifications

These are the decisions we make on every KDP formatting walkthrough job, and the reason for each one.

Element
How we build it
Why it matters
Paperback trim
Common sizes include 5 by 8, 5.5 by 8.5 and 6 by 9 inches, and KDP supports many others, but only listed sizes qualify for expanded distribution.
Trim size sets your page count and printing cost, so it should be chosen before any layout work begins.
Margins
The inside margin increases with page count, from 0.375 inch for the shortest books to 0.875 inch for the longest, and the outside margin is at least 0.25 inch.
This prevents text from being lost at the binding and keeps the book comfortable to hold open.
Bleed
0.125 inch on the top, bottom and outside edges whenever an image or colour reaches the edge of the page, and none when nothing does.
Bleed allows for the small variation in trimming so that no white sliver appears at the edge.
Images
Photographs and artwork at 300 dpi at the final printed size, in RGB or greyscale for the interior as the platform requires.
Images at this resolution print crisply, whereas lower resolution files look soft in a physical copy.
Page count
Paperbacks run from 24 to 828 pages and hardcovers from 75 to 550 pages, and some paper and ink options limit the range further.
The range sets what KDP will accept, and your final count decides the spine width.
Ebook cover
About 2,560 by 1,600 pixels, with an ideal height-to-width ratio of 1.6 to 1, in JPG or TIFF format and under the file size limit.
A properly sized cover stays sharp as a thumbnail and as a full-screen image on every device.
Quality

How to check a file before you upload it to KDP

Use the KDP online previewer

Upload the files in a draft title and read every page of the preview, looking for margin warnings, bleed errors and any text that sits near the trimmed edge.

Order a printed proof copy

A physical proof shows what no screen can: whether the gutter is comfortable, whether the text colour is dark enough and whether the cover colours print as you expected.

Check the file in the Kindle previewer

Open the ebook in the desktop previewer on phone, tablet and e-reader views, and change the font size to confirm that headings, images and the contents list all behave properly.

Run EPUB validation

Use EPUBCheck or a similar tool to find structural errors, since a file with errors may display on one device and fail on another, or be rejected during upload.

Compare the page count with the cover

Confirm that the page count in the cover template equals the final interior page count, because a difference of even a few pages changes the spine width.

Read the first and last ten pages on paper

Front and back matter carry the most formatting detail and the most errors, so print them and read slowly for margins, page numbers and missing pages.

Publishing a first paperback

A safe, ordered path to a file that passes on the first upload, with the margin and cover steps explained so that nothing important is missed.

Fixing a rejected file

When KDP sends an error message, the specification and checklist sections help you find the cause quickly and correct only what needs to be changed.

Preparing a series for KDP

Setting the same margins, fonts and structure for every book keeps the series consistent and shortens the work for each new volume.

Preparing an ebook for Kindle

The ebook section explains structure, contents and cover requirements, so that the Kindle edition looks professional on every device and setting.

Checking work done by a freelancer

Use the checklist and test steps to confirm that files delivered to you meet the KDP specifications before you upload and publish them.

Our standard

The standards we apply to KDP files

01

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.

02

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.

03

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.

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.

Key terms

KDP formatting terms explained

Trim size

The finished page size of a printed book after the pages are cut, such as 5.5 by 8.5 inches, which sets your page count, printing cost and margins.

Bleed

The extra area of an image or colour that extends beyond the trim edge, so that when the page is cut there is no white sliver at the edge.

Safe zone

The area inside the trim where text and key artwork are safe from being cut off or lost in the binding because of normal trimming variation.

KPF

Kindle Package Format, the file produced by Kindle Create, which KDP accepts for ebooks that use the Kindle-specific layout and typography tools.

Case laminate

A hardcover with the cover design printed directly on the board and laminated, so the book has no separate dust jacket and is available on demand.

Previewer

The tool inside KDP that shows how your uploaded file will look and flags margin, bleed and image problems before you publish the book.

Who it is for

Who this KDP formatting guide is for

First-time KDP authors

You want a clear path through the rules that explains why each requirement exists, so you can avoid rejection and publish with confidence.

Authors who received a KDP error

You need to know what a margin or bleed message means and how to fix it without rebuilding the whole book from scratch.

Authors adding print to an ebook

Moving from ebook to paperback brings new rules, and this guide lays out the differences in plain language.

Authors preparing a hardcover

Case laminate hardcovers have unique cover geometry, which the guide explains with the figures you need.

Authors reviewing a formatter's work

A checklist lets you verify delivered files against KDP requirements before you commit to uploading them.

Series authors who want consistency

Shared settings and a repeatable process make each new book faster to prepare and more uniform across the series.

Guarantee

What this guide rests on

Rules from KDP

We follow the published specifications for trim, margins, bleed and file types, and we update the guidance whenever Amazon changes its requirements.

Tested in practice

The advice reflects files that were actually uploaded and passed the previewer, not theory, so that each step has been proved on real books.

Plain language

We explain each requirement in everyday words, with the numbers you need, so you can follow the guide without any previous experience of print production.

How we think

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.
