KDP A+ Content: modules, image rules and what Amazon rejects

KDP A+ Content is a set of image and text modules that sit below your book description on Amazon. Instead of one block of text, the detail page shows a wide banner, a look inside, a quote or your series. You build it in KDP's A+ Content Manager once the book is live or on pre-order. This guide covers the modules, the rules for images and copy, what Amazon rejects, and a five-module layout that suits most books.

What A+ Content is and where it appears

A+ Content shows on the detail page in the “From the Publisher” section, below the description. Most readers have to scroll to reach it. Those who do are interested and looking for one last reason to buy: what does it look like inside, what will I learn, who wrote it?

The basics according to KDP's help (November 2026):

Image rules: what Amazon accepts

• Format: JPG or PNG in the RGB colour space. CMYK isn't supported, so don't upload your print cover file.
• File size: each file under 2 MB.
• Resolution: at least 72 dpi; the A+ Content Manager shows the exact pixel size for each module when you add it.
• No animation: GIFs and other animated images are prohibited.
• Readable on a phone: no blurry images, no watermarks, no text too small to read on mobile.
• Fresh images: images must be unique to A+ and not repeat those in the product gallery.
• Alt text: describe each image well enough to help screen reader users.
• One logo: a single brand or publisher logo at most.
• Rights: you need all rights to the images, logos and symbols you use.

A common stumbling block is images with too much small text. A line that looks big on a 970-pixel banner on your desktop is tiny on a phone.

What A+ Content can't include

KDP's A+ guidelines are stricter than the rules for the book description. Among other things, these are not allowed:

• Prices and promotions: prices, discounts, “buy now”, “add to cart”, words like “affordable”, “bonus”, “free”
• Customer reviews: none at all; quotes from publications or public figures up to four, with names and publication titles
• Time-sensitive language: “new”, “now”, “the best yet”, holiday references
• Boasting: “#1 rated”, “top-rated”, satisfaction guarantees
• Awards older than two years, and newer ones only with date and granting organisation
• Comparisons with other people's books: comparison charts may only show books from your own KDP account
• Links and redirects to other sites, including your other products, plus contact details and QR codes
• Health claims and unsupported claims like “proven” or “tested”

KDP's style rules also apply: spell out numbers under ten, capitalise the major words in headers, and keep bold and italics for headings or a few words.

Five modules that work for most books

1. A banner with the promise. A wide image in your cover's style with one line on what the book does for the reader.
2. A look inside. A spread, a recipe, a checklist. Nothing sells nonfiction like the page where it gets concrete.
3. A quote from the book. One strong sentence, set large. For a novel it does the job of a sample.
4. The series or editions. A comparison chart of your own books, if there are several.
5. The person behind the book. A portrait and two sentences on why you could write this book.

A novel rarely needs five modules. A banner, a quote and the series are often enough; few novel readers read much more below the description.

Common A+ Content mistakes

1. Using the print PDF as a source. Print cover files are CMYK and get rejected. A+ needs RGB.
2. Reusing gallery images. The cover again as a module isn't allowed and adds nothing.
3. Adding reviews. Customer quotes are prohibited, even inside an image.
4. Too much text in the image. Unreadable on a phone and a reason for rejection.
5. Only one marketplace. If you sell on amazon.com and amazon.co.uk, you create A+ Content for each.

A+ modules from your book and cover

With Bookfairy A+ Content you get the modules as finished images in the sizes Amazon asks for, with copy that matches your book description: banner, comparison, quote, author, image with text. One module costs $4.8040 tokens, a set of five $9.6080 tokens. The description above it comes from the blurb tool.
