KDP Paperback: A Guide to Print-on-Demand on Amazon
While ebooks dominate the digital landscape, the timeless appeal of a physical book is undeniable. For independent authors, Amazon’s Kindle Direct Publishing (KDP) platform offers a revolutionary solution to sell physical copies of their work without any upfront investment: the KDP paperback.
KDP paperback is a print-on-demand (POD) service. This incredible technology means your book is printed one copy at a time as customers order it. There are no expensive print runs, no inventory to store, and no risk of unsold books. It is the most powerful and accessible way for any author to see their work in print and sell it on the world’s largest bookstore.
Key Takeaways & Summary
Print-on-Demand (POD) is Key: KDP paperback is a POD service. A book is only printed when a customer makes a purchase, meaning there are zero upfront inventory costs for the author.
Two Files are Required: To publish a paperback, you need two professionally formatted, print-ready PDF files: one for the book’s interior and one for the full wraparound cover.
Royalties are 60% Minus Print Cost: Your royalty for a KDP paperback is a fixed 60% of your list price, minus the cost of printing the book.
A Professional Product is a Must: To compete, your paperback must be professionally designed, inside and out. This includes both the cover and the interior typesetting.
The Two Essential Files for Your KDP Paperback
Publishing a paperback on KDP requires a higher level of technical precision than an ebook. You will need two specific, professionally prepared files.
1. The Print-Ready Interior PDF
This is the file for the inside of your book. It is a static, fixed-layout design.
What it is: A PDF file where every page is meticulously designed, or “typeset.” This includes choosing your trim size (e.g., 6″ x 9″), setting the margins (including a wider “gutter” for the binding), selecting professional fonts, and adding page numbers and headers.
Why it’s crucial: A poorly formatted interior looks amateurish and is difficult to read. Professional interior design is essential for a good reader experience.
2. The Print-Ready Wraparound Cover PDF
This is the file for the outside of your book.
What it is: A single PDF file that includes the front cover, the back cover, and the spine, all laid out to precise dimensions.
Why it’s crucial: The spine width is determined by your final page count and the paper type you choose. It must be exact. KDP provides a free cover template calculator to generate the precise dimensions for your designer.
How KDP Paperback Royalties Work
The royalty calculation for a paperback is different from an ebook because it has to account for the physical cost of printing.
The Formula: (List Price x 60%) – Printing Cost = Your Royalty
Printing Cost: This is the fixed amount KDP charges to print your book. It depends on your page count, trim size, and whether you use black ink or more expensive color ink.
Example:
You price your 300-page, 6″ x 9″ paperback at $15.99.
The printing cost for this book on Amazon.com is $4.45.
Your royalty calculation is: ($15.99 x 0.60) – $4.45 = $9.59 – $4.45 = **$5.14** per copy sold.
The KDP Paperback Publishing Process
The process on the KDP dashboard is very similar to publishing an ebook.
Start a New Title: From your KDP Bookshelf, click “Create” and choose “Paperback.”
Enter Your Paperback Details: You will enter your book’s title, description, and keywords. You will also need to select your trim size, paper type (cream or white), and cover finish (glossy or matte).
Get Your Free KDP ISBN: KDP will assign you a free ISBN for your paperback, or you can use your own if you’ve purchased one from a source like Bowker.
Upload Your Files: You will upload your two print-ready PDF files (interior and cover).
Preview Your Book: KDP’s online previewer is a crucial step. It will show you exactly how your printed book will look and will flag any potential issues with margins or bleed.
Set Your Price: You will set your list price for each Amazon marketplace.
Publish: After you approve the digital proof, you can hit “publish.” Your paperback will be available for sale on Amazon within a few days.
Our Amazon KDP publishing services can manage this entire technical and strategic process for you, ensuring a flawless print-on-demand book.
