Kindle Direct Publishing

Kindle Direct Publishing (KDP) is Amazon’s self-publishing service for eBooks, paperbacks, and hardcovers. It is best for authors seeking Amazon storefront distribution and print-on-demand without an upfront publishing fee. Its strongest case is control over rights and formats; its main compromises are format exclusions and distribution conditions attached to some Kindle eBooks.

Overview

KDP lets authors publish digital and print editions for sale on Amazon while retaining full rights to their books. Paperbacks and hardcovers are printed when orders arrive, avoiding the need to purchase inventory in advance. Fulfillment is global, and Expanded Distribution can extend print availability to bookstores, online retailers, libraries, and academic institutions.

Its storefront network spans Amazon.com, Amazon.ca, Amazon.co.uk, Amazon.de, Amazon.fr, Amazon.it, Amazon.es, Amazon.co.jp, Amazon.com.au, Amazon.nl, Amazon.pl, Amazon.se, Amazon.ie, and Amazon.com.be. That reach suits authors whose buyers use Amazon, though KDP is a book-publishing service rather than a broad merchandise platform.

Key features

Formats and preparation

KDP accepts eBook manuscripts in DOC, DOCX, KPF, and EPUB, as well as HTML, RTF, TXT, and PDF. Kindle Create runs on Windows and Mac and can prepare manuscripts exported from Microsoft Word, Apple Pages, or Google Docs. Design and mockup tools support presentation, making the service practical for authors preparing both digital and print editions.

Royalties and print-on-demand

eBook royalty options are 35% and 70%; the 70% option is limited to certain territories and subject to delivery costs. Print books can earn up to 60% royalties, with printing costs deducted from print royalties when an order ships. On-demand printing reduces inventory risk, but the royalty figures are not a guarantee of take-home earnings: the 70% eBook option has eligibility conditions, and print production costs affect the payout.

Promotion and exclusivity

Authors can use Amazon Advertising to promote eBooks and paperbacks, and share Kindle Instant Book Previews and sample chapters. KDP Select is a free 90-day program for Kindle eBooks that includes Kindle Unlimited and eligibility for Free Book Promotions and Kindle Countdown Deals. The trade-off is meaningful: for each enrollment period, the Kindle eBook must be exclusive to the Kindle Store. Print, video, audio, and other formats can still be distributed elsewhere, but authors who want the same eBook sold through other channels should not enroll.

Publishing limits and account security

KDP allows up to two new titles per book format per week for creation and first-time submission, with separate limits for each format. It does not accept magazines, periodicals, calendars, or spiral-bound books. KDP recommends a strong, unique Amazon account password and two-step verification. Authors can request phone support through the KDP Contact Us Form.

Pricing

KDP is free to publish: the Kindle Direct Publishing plan costs free, billed as free to publish. It covers eBooks, paperbacks, and hardcover books, subject to the excluded formats above. Print costs are deducted from print royalties when an order ships, so free publishing does not mean print production has no cost; the author is not asked to buy stock upfront.

There is no paid tier to unlock these publishing formats in the plan described. Authors choosing KDP Select also pay no enrollment fee, but the 90-day commitment includes Kindle Store exclusivity for the enrolled eBook. That makes KDP financially accessible for authors who can accept its distribution terms, but less suitable for those who need unrestricted eBook channel distribution during Select enrollment.

Platforms

KDP supports Android, iOS, macOS, web, and Windows. Kindle Create is specifically available for Windows and Mac, giving desktop authors a preparation option alongside the web publishing service.

Who it's for

KDP is a strong fit for independent authors who want eBooks and on-demand print editions listed across Amazon storefronts, retain their rights, and avoid buying print inventory before sales. It also suits authors willing to trade temporary eBook exclusivity for KDP Select’s Kindle Unlimited inclusion and promotion eligibility.

It is a poor fit for publishers of magazines, periodicals, calendars, or spiral-bound books, and for authors who need an enrolled Kindle eBook distributed beyond the Kindle Store during a Select term. Authors should also weigh the per-format weekly title submission limit if they plan a high-volume launch schedule.

Pros and cons

• Pro: No publishing fee. Authors can publish eBooks and print editions without a subscription or upfront inventory purchase.
• Pro: Rights remain with the author. KDP states that authors retain full rights to their books.
• Pro: On-demand print and broad reach. Paperback and hardcover orders trigger printing, with Amazon storefronts and Expanded Distribution extending potential availability.
• Con: Select restricts eBook distribution. The enrolled Kindle eBook must remain exclusive to the Kindle Store for each 90-day enrollment period.
• Con: Royalties have conditions and deductions. The 70% eBook option is territory-limited and subject to delivery costs; print costs are deducted from print royalties.
• Con: Several formats are excluded. Magazines, periodicals, calendars, and spiral-bound books cannot be published through KDP.

Alternatives

For authors comparing print-on-demand services, the Print-on-Demand Platforms directory is a useful starting point.

Choose Printful instead when you need a free-plan print-on-demand service with custom products, unlimited stores, and 10 Quick Stores. Printify is another option for merchants starting a business; its free plan allows five stores per account. Gooten may suit sellers who prefer no membership fee and pay production and shipping costs as orders are processed.

Gelato offers a free plan with two connected ecommerce stores and two account users. Inkthreadable has no subscription or sign-up fee, with product, printing, and separate shipping charges when orders are placed. PrintKK provides a free plan with unlimited product designs, mockups, store integrations, custom API integration, and 30 one-time AI tokens.

Fourthwall is worth considering if you want a customizable shop, catalog products, memberships, and social selling integrations on its free plan. Prodigi offers a free account with 3D product mockups, branded packing slips, and email and live chat support. These services address broader print-on-demand or shop needs; KDP is the more direct fit when the product is a book for Amazon.

Verdict

KDP is a clear choice for authors who want Amazon distribution, rights retention, and on-demand print without paying to publish. Its royalty options and broad storefront reach are useful, but eligibility terms, print-cost deductions, excluded formats, and KDP Select exclusivity deserve attention before committing. Choose another service if you need to publish an excluded format or keep a Select-enrolled Kindle eBook available outside Amazon during its enrollment term.
