The Complete Amazon KDP Self-Publishing Guide (2026)
Self-publishing on Amazon KDP requires a free account, a correctly formatted manuscript, a cover built to KDP's dimension specifications, and pricing that puts you in the correct royalty tier. Authors earn 35% to 70% royalties depending on book price, distribution selections, and whether the eBook is enrolled in KDP Select.
What this guide covers: creating your KDP account correctly the first time, preparing manuscript and cover files to specification, understanding the royalty structure in detail, writing a book description that converts browsers into buyers, choosing categories and keywords that drive discoverability, setting up IngramSpark alongside KDP for global distribution without a listing conflict, and the specific errors that most commonly cause a self-published book to stall before it gains traction.

Go to kdp.amazon.com and sign in with your existing Amazon account or create a new one. KDP treats your author account and your buyer account separately, you can use the same login, but the dashboards are distinct. During setup you will be prompted for tax information. US authors complete a W-9. Non-US authors complete a W-8BEN. Complete this before uploading any title, because tax withholding affects your royalty rate on US sales.
Your bank account for royalty payments must be set up before any book goes live. KDP pays monthly, approximately 60 days after the end of the sales month. US bank accounts receive direct deposit. Non-US authors typically receive wire transfer, which carries a small fee per payment.
Step 2: ISBN and Imprint Decisions
KDP offers a free ISBN for print books. That ISBN is registered to Amazon and lists "Independently published" as the publisher on the copyright page and in library catalogues. For most authors publishing a first book, this is acceptable and costs nothing.
Authors who want their own imprint name on the copyright page must purchase an ISBN from their country's national ISBN agency (Bowker in the US at $125 per ISBN, or $295 for 10). A purchased ISBN allows you to set any publisher name in the metadata. This matters for authors whose books will be reviewed by trades, submitted to libraries, or used in academic settings where "independently published" affects how the title is received.
If you plan to distribute through IngramSpark alongside KDP, which is the professional setup for any book targeting international distribution, you need your own purchased ISBN. Ingram and KDP cannot share a KDP-assigned ISBN. This is the single most common setup mistake that forces a full relaunch.
Step 3: Manuscript Formatting to KDP Specification
KDP accepts Word documents (.docx) and PDF files for print interiors. For eBooks, KDP accepts Word, ePub, and HTML. Word documents go through KDP's automatic conversion engine, which produces inconsistent results for complex layouts, multi-column content, or books with many images. For print books, submit a properly formatted PDF.
KDP's print interior specifications depend on your trim size. Common trim sizes are 6x9 inches (standard nonfiction), 5.5x8.5 inches (standard fiction), and 8.5x11 inches (workbooks and large-format nonfiction). Margins must follow KDP's minimum requirements, which increase with page count. For a 250-page 6x9 book, the minimum inside (gutter) margin is 0.75 inches and the outside margin is 0.5 inches. Embedded fonts must be included in the PDF export.
The most common interior formatting errors that trigger KDP rejection: fonts not embedded, bleed settings incorrect for full-bleed images, text too close to the spine in the gutter, and low-resolution images below 300 DPI. KDP's print previewer will flag most of these, but not all. A professional formatter catches them before submission.
Step 4: Cover Design to KDP Specification
The cover file must include front, spine, and back in a single flat PDF or JPG. The spine width is calculated from your exact final page count and paper type (white or cream). If the interior changes by even 10 pages after the cover is built, the spine width is wrong and the cover file must be rebuilt. Always finalise the interior layout and lock the page count before building the cover.
KDP provides a Cover Creator tool that generates basic covers from templates. These templates are immediately recognisable as self-published to any reader who has spent time on Amazon. If professional positioning is a priority, a custom cover by a genre-specialist designer is not optional, it is the single highest-ROI production investment a self-published author makes.
Cover resolution must be at least 300 DPI at final print dimensions. The cover PDF must include a bleed of 0.125 inches on all sides. KDP's Cover Calculator (available in the KDP dashboard) generates the exact template dimensions for your specific page count and trim size.
Step 5: Categories, Keywords, and Book Description
KDP allows you to select two BISAC categories and up to seven keywords during setup. These two fields have more impact on whether a reader finds your book than almost any other setup decision. The BISAC categories shown during KDP setup are not the same as Amazon's actual category tree, which is more granular and more useful for discoverability. After publishing, additional categories can be requested by emailing KDP support with your ASIN and the exact category path, authors can add up to 10 categories total this way.
Keywords function as search terms. Seven slots are available. Use each slot for a distinct multi-word phrase that your target reader actually searches, not individual words, and not repetitions of your title. Tools like Publisher Rocket (paid) or Amazon's own autocomplete are useful for identifying high-traffic, low-competition keyword phrases specific to your genre and subject.
The book description on Amazon supports a limited subset of HTML formatting tags. Bold, italic, bullet lists, and headers all render correctly. A description with visible structure consistently outperforms a block of plain text. The opening sentence must do one thing: make the reader who is already interested in the topic want the specific book rather than the 40 others in the same category.
Step 6: Pricing and Royalty Structure
KDP eBook royalties are 70% for books priced between $2.99 and $9.99, and 35% for books priced below $2.99 or above $9.99. The 70% rate also carries a delivery charge per megabyte of file size, for text-only eBooks, this is negligible. For heavily illustrated eBooks, it can meaningfully reduce the effective royalty.
Print royalties are calculated as a percentage of the list price minus the printing cost. The printing cost varies by page count, trim size, and paper type. A 250-page 6x9 paperback on white paper costs approximately $3.65 to print. At a list price of $14.99 with 60% royalty and expanded distribution enabled, the per-copy royalty is approximately $5.35 after printing cost deduction.
Expanded distribution reduces the print royalty percentage but makes the book available to retailers and libraries outside Amazon. For most books, enabling expanded distribution is correct, because the alternative is Amazon-only availability for print copies.

KDP Select requires Amazon exclusivity for eBook distribution in 90-day renewable periods. In exchange, the eBook is included in Kindle Unlimited (readers pay Amazon a subscription; you earn per page read), royalties are higher in some non-US markets, and promotional tools including Kindle Countdown Deals and Free Book Promotions are available.
KDP Select makes economic sense for genre fiction authors with a backlist, Kindle Unlimited readers consume fiction voraciously and the per-page-read rates generate meaningful income at volume. For nonfiction, professional, and business books, KDP Select exclusivity sacrifices Apple Books, Kobo, and Google Play sales in exchange for promotional tools that typically matter less to the audience. The default position for most nonfiction and business authors is to skip Select and publish wide from launch.
Step 8: IngramSpark Setup for Complete Global Distribution
KDP and IngramSpark serve different parts of the global book market. KDP handles Amazon's global marketplaces directly. IngramSpark connects books to 40,000+ retailers, libraries, schools, and wholesalers, the same distribution network that traditional publishers use. Using both platforms simultaneously gives a self-published book complete global distribution.
The professional dual-platform setup: use your own purchased ISBN on both platforms. In IngramSpark, set the Amazon sales channel to off. This means Amazon orders print copies through KDP's manufacturing (better royalty for Amazon sales) while all other channels, bookshops, libraries, international wholesale, are served by Ingram. This avoids listing conflicts and maximises per-copy earnings on Amazon while achieving full global distribution through Ingram's network.
IngramSpark is more technically demanding than KDP. Wholesale discount settings must be set to 55% for bookshops to order profitably. Returns policy configuration affects whether physical bookshops will stock the title. Cover and interior file specifications differ slightly from KDP. These configuration decisions, once wrong, require a takedown and republish cycle to fix.
The 8 Errors That Kill Most Self-Published Books
The following mistakes account for the majority of underperforming self-published books. Most are invisible to the author during production but immediately visible to readers, reviewers, and Amazon's algorithm.
Wrong spine width on the cover file. Calculated from exact final page count. If the interior changes after the cover is built, even by 10 pages, the spine width is incorrect and the cover must be rebuilt.
KDP-assigned ISBN used on IngramSpark. This creates a listing conflict and is flagged immediately. Requires full withdrawal and relaunch with a purchased ISBN.
IngramSpark Amazon channel left on. This causes duplicate Amazon listings, suppresses the KDP listing, and creates price discrepancies that Amazon flags.
Wholesale discount set below 55% in IngramSpark. At 40%, Ingram's wholesale margin is insufficient for retailers to order profitably. The book is technically available but will not be stocked.
Wrong BISAC categories selected during setup. Categories determine which Amazon bestseller lists the book can rank on. Wrong categories mean the book never appears in the relevant lists regardless of sales velocity.
Book description written as a synopsis rather than a sales argument. The description's job is not to summarise the book, it is to persuade a reader who already clicked that they need this specific book.
Cover design that signals self-published. Genre readers make buy/no-buy decisions in under 3 seconds on thumbnail size. A cover that reads as amateur disqualifies the book before the description is read.
Launching without a review strategy. Amazon's algorithm requires early sales velocity and early reviews to surface a book in search results and also-bought sections. A launch week with zero reviews enters a competitive category with no social proof, which suppresses organic visibility from day one.
