What the requirements for Amazon KDP cover

When authors ask about the requirements for Amazon KDP, they usually mean three things: account and tax setup, content rules, and submission formats. At a practical level you must register with a working email, enter tax and payment information, and provide accurate author and title metadata that matches your manuscript. Content must be original or properly licensed; KDP asks authors to disclose AI-generated text or images when used. For help on handling AI drafting and disclosure in your files, see our Amazon KDP AI Writing resource — it explains how to note AI involvement and avoid common pitfalls before upload.

KDP enforces rules that protect readers and authors: no plagiarism, no trademark abuse, and no prohibited content. You’ll also need to choose rights (worldwide or specific territories) and determine distribution channels. These choices affect pricing, royalty rates, and whether your book can be matched to print-on-demand networks.

Files, covers, and formatting essentials

File types and size

Ebooks: KDP accepts EPUB for reflowable ebooks and fixed-layout formats when needed. EPUB is the modern standard; create and validate an EPUB that includes embedded fonts and clean, consistent HTML. If you’re converting between formats, a reliable EPUB converter will save time and prevent errors.

Images and quality

All images for interior or cover must be high-resolution—300 DPI is the standard. Avoid crop marks, registration marks, or any extra printer metadata inside your PDF. Large photos increase file size, so balance clarity with file limits.

Cover requirements

Paperback covers must be a single, continuous image spanning front, back, and spine at the correct dimensions for your trim size, with 0.125″ bleed and a 0.25″ safe zone for critical text. Flatten layers and embed fonts to prevent rendering errors. For simple, repeatable cover production you can use a book cover generator to build compliant covers quickly and avoid manual sizing mistakes.

Proofing and preflight

Preview every upload with KDP’s previewer and order a proof copy before wide release. Proofs show how trim, gutters, and margins work in real life. Fixing layout issues after a live release is time-consuming and can hurt visibility.

Account details, rights, pricing, and scaling your releases

Metadata and ISBNs

Your manuscript metadata—title, author name, subtitle, and description—must match what’s inside the file. Each format needs a unique ISBN if you supply one; KDP also offers a free ISBN for paperbacks. Be deliberate about author name variations and series metadata to avoid catalog fragmentation.

Royalties and pricing

For Kindle eBooks, the common royalty bands are 35% and 70%, with the higher tier having requirements on list price and delivery fees. Paperbacks use a cost model where printing cost affects the author’s net. Test pricing in small increments and use KDP reports to watch how price changes impact royalties.

AI content and disclosure

Amazon requires disclosure when substantial content or images are AI-generated. That affects metadata and may change how you present creation notes in your front matter. Follow the Amazon KDP AI Writing guidance linked earlier to make the disclosure clear and consistent.

Publishing across platforms efficiently

If you plan to publish multiple titles or distribute to Kobo, Apple Books, Draft2Digital, and Ingram in addition to KDP, manual uploads become a bottleneck. A unified multi-platform publishing service can automate uploads, map metadata across stores, and batch-process CSVs for hundreds of titles. At scale this saves roughly 90% of time spent on repetitive uploads, reduces human error, and makes wide distribution practical.

When you prepare files for many platforms, remember each store has slight differences—cover spine calculations, EPUB validation quirks, and page-count minimums. Using a central workflow that understands platform-specific intelligence avoids rework and rejected uploads. If you need structured tools to create print-ready interiors or to generate EPUB files en masse, a quality EPUB converter is an efficient step in the pipeline. Likewise, using a book cover generator helps keep design consistent across formats without repeated manual resizing.

Automate the upload. Own the distribution. For authors publishing seriously, this is an obvious upgrade.

FAQ

Q: What file formats does KDP accept?

A: For ebooks use EPUB; for paperbacks use a print-ready PDF with embedded fonts. Images should be 300 DPI.

Q: How many pages does a paperback need?

A: Paperbacks need a minimum of 24 interior pages. Different trim sizes may affect layout but the minimum page count is enforced.

Q: Do I need to disclose AI-generated content?

A: Yes. Amazon asks authors to disclose AI-generated text or images when they make up a substantial portion of the work. Follow KDP guidance for how to note this in your manuscript and metadata.

Q: Can I use one ISBN for ebook and paperback?

A: No. Each format requires its own ISBN if you provide one. KDP can supply a free ISBN for paperbacks if you prefer.

Q: How do I avoid upload rejections?

A: Follow formatting specs, embed fonts, use the right file types, check image resolution, and ensure metadata matches the manuscript. Preview proofs before release.

Final thoughts

Publishing on KDP is straightforward when you follow the specs, but managing many titles across stores is where most errors and wasted time happen. Use tools that convert and validate EPUBs, generate compliant covers, and batch-upload with CSVs. These steps reduce rework, keep listings accurate, and let you focus on writing.
