Short answer: A+ Content is the panel of images, text and comparison tables that sits under the description on an Amazon book page. You add it free from your KDP Marketing page → A+ Content → Manage A+ Content, and one project can cover the ebook, paperback and hardcover. The main banner image needs to be at least 970 × 300 pixels (1940 × 600 recommended). Amazon says compliant content appears within eight business days.
What it looks like on a book page
On a phone, A+ Content appears under the description and before most of the reviews, which is why it matters more than its place on a desktop suggests. It gives you room the 4,000-character description doesn’t: pictures of the inside of the book, a series line-up, the author with a face, and quotes from people readers trust.
Five A+ layouts that work for books
These are the patterns we use most. Each uses modules KDP offers.
- The promise banner. A wide image with a short headline over it (the Standard Image & Text Overlay module). One sentence that says what the book does for the reader, not “a gripping read”.
- Inside the book. Three images of real spreads (the Three Images and Text module). This works well for non-fiction, cookbooks, workbooks and picture books, where the reader wants to see the pages before buying.
- The series line-up. The Comparison Chart module, which Amazon lets you use to compare up to five of your own books: reading order, one line each, and a clear “start here”.
- Why trust this author. An author photo with two or three lines of credibility (the Single Left Image module). For non-fiction this does more than any quote.
- What readers get. A short list of what’s inside, or for fiction, the tropes and comparable titles your readers search for, in plain text large enough to read on a phone.

Image sizes for each module
From Amazon’s A+ Content Examples page, read 30 September 2026:
| Module | Minimum | Recommended | Notes |
|---|---|---|---|
| Standard Image & Text Overlay | 970 × 300 px | 1940 × 600 px | The banner. The text box sits over the image at 70% opacity |
| Standard Single Left Image | 600 × 180 px | 600 × 600 px | Image with text beside it |
| Standard Three Images and Text | 300 × 300 px | 600 × 600 px | Three images, each with a caption |
| Comparison Chart | 150 × 300 px | Compare up to five of your own books | |
| Standard Single Image & Sidebar | 300 DPI, JPG or PNG | ||
| Standard Technical Specifications | A table of up to 16 rows | ||
| Standard Product Description Text | Up to 6,000 characters of text |
File rules, from Amazon’s A+ Content Guidelines: JPG or PNG in RGB (“CYMK colorspace is not supported”), no animated images, and each image unique to A+ rather than reused from elsewhere. Amazon’s pages disagree on file size: the guidelines say “under 2 MB”, the examples page says 3 MB. Keep every file under 2 MB and you meet both.
Design at the recommended size, not the minimum. On a phone the banner is shrunk to the screen width, so any text inside the image needs to be large: Amazon rejects “small text that is unreadable when shown on mobile devices”.
The rules that get A+ Content rejected
All from Amazon’s A+ Content Guidelines:
| Not allowed | Examples |
|---|---|
| Prices and promotions | “Only £2.99”, “buy now”, “add to cart”, “get yours now” |
| Customer reviews | Star ratings or quotes from Amazon reviews |
| Time-sensitive words | “now”, “new”, “latest”, “on sale now”, holiday references |
| Too many quotes | More than four quotes or endorsements; each must be attributed |
| Guarantees | Refund or returns promises |
| Competitor comparisons | Comparing your book to another author’s; a chart of your own books is fine |
| Superlative claims | “#1 rated”, “top-rated”, “100% satisfaction guaranteed” |
| Contact details and links | Websites, emails, phone numbers, “visit my site” |
| Old awards | Awards more than two years old, or without the date and the organisation |
| Poor images | Blurry, low quality, watermarked, or text too small for a phone |
Two that catch authors out: review quotes from Amazon customers (use a published review or a named author’s endorsement instead) and a website address in the author panel.

- Choose the marketplace (Amazon.co.uk and 12 others are supported) and click Manage A+ Content.

Amazon matches content to marketplaces by language: an English project can show on Amazon.co.uk, Amazon.com and the other English-language stores it supports.
Want A+ Content that looks like the example above?
We design the modules to Amazon's sizes and rules, write the copy, and send you the files ready to upload. From £89 for one book.
See A+ ContentDoing it yourself: what you need
- Design tool: Canva, Affinity (free for individuals) or Photoshop. Set the canvas to the recommended pixel size before you start.
- Real pictures of your book: photos or clean renders of real spreads. Mock-ups that show pages that aren’t in the book cause more problems than they solve.
- A 1940 × 600 px banner, three 600 × 600 px images and an author photo covers the five layouts above.
- Copy written for a phone: short lines, large type, one idea per module.

Who wrote this. I am Robert Prime. I run publishing.co.uk, which designs A+ Content for books, including the example above. The sizes and rules on this page are Amazon's, quoted from its KDP help pages; where Amazon's own pages disagree, as they do on file size, I've said so.
