Few things are as quietly frustrating as a beautiful A+ design that uploads blurry, gets cropped oddly, or is rejected for the wrong dimensions. Getting the Amazon A+ content image size right the first time saves you the resize-and-reupload loop, and it is the difference between crisp modules and a soft, amateurish page. This is the practical cheat sheet: the module dimensions, the file rules, and how Basic and Premium differ.
One note before the numbers: Amazon occasionally adjusts template specifications, and the exact required size is always shown in the Seller Central upload window for each module. Treat the figures below as the working reference, and confirm against the upload dialog when you build. Bookmark this page, because unlike the fast-moving policy changes elsewhere on Amazon, module dimensions stay fairly stable, which makes a reliable cheat sheet genuinely useful to keep on hand rather than re-hunting the specs every time you build a new page.
Two things go wrong when sizes are off. Upload an image smaller than the module's native resolution and Amazon scales it up, which softens and blurs it. Upload something at the wrong aspect ratio and it gets cropped in ways you did not intend, cutting off text or product. On top of that, oversized files that blow past the 2 MB limit either get rejected or get compressed so hard they lose quality. Correct dimensions are not a nicety, they are what keeps your page looking professional.
These are the working dimensions for the common A+ modules:
Match the module you are filling to its size here, and confirm the exact figure in the upload window. If a number in the dialog differs from this list, trust the dialog, since that is the spec Amazon is enforcing for that specific template at that moment.
Beyond dimensions, every A+ image must meet a few file rules: JPEG or PNG format, RGB color, and a file size under 2 MB per image. Avoid animated formats. A common mistake is exporting in CMYK, which is meant for print and can shift colors or get the file rejected outright, so always export in RGB for the web, and double-check the color mode in your export dialog before you upload.
The tiers are not interchangeable. Premium A+ modules are wider, roughly 1464 pixels for full-width formats, nearly double the Basic 970-pixel class, and Premium adds video and interactive formats with their own specs. If you upgrade a page from Basic to Premium, you generally need to re-export the imagery at the larger dimensions rather than reuse the Basic files, or they will look soft in the wider frame.
For the crispest result, design at roughly twice the target dimensions and export down to size at high quality, staying under the 2 MB limit. Working at 2x gives you sharp detail and clean text, and downscaling a large, high-quality image almost always looks better than upscaling a small one. This single habit, designing at 2x and scaling down, fixes the large majority of soft or fuzzy A+ imagery on its own.
Correct dimensions get your image accepted, but remember it will be displayed much smaller on a phone. Sizing the file correctly and making the content legible at mobile scale are two different jobs. Keep on-image text large and minimal so that when the module is squeezed to phone width, the words still read. A technically correct image that becomes an unreadable smear on mobile has only solved half the problem.
Two numbers get confused here, and confusing them is behind most soft A+ pages. Dimensions are how many pixels wide and tall your image is. Resolution, in the sense that matters online, is really about whether the image has enough real pixels to look sharp at the size it is displayed. An image can have the right dimensions on paper but still look soft if it started life small and was enlarged to reach them. The rule of thumb: never scale up. Start with an image that has plenty of native detail, then bring it down to the target dimensions. That way the Amazon A+ content image size you upload is backed by real pixels, not stretched ones, and it stays crisp on both retina screens and standard displays.
This matters more in 2026 because the content quality score explicitly weighs image quality. A blurry module does not just look bad, it can pull your page toward a Needs Improvement rating, so sizing correctly is now a quality signal, not only an aesthetic one.
Suppose you are building a five-module Basic page for a water bottle. Your full-width hero exports at 970 by 300. Your three feature cards export at 300 by 300 each. Your single comparison chart has three columns at roughly 150 by 300 each. Your brand logo sits at 600 by 180. Every file is RGB JPEG, each comfortably under 2 MB, and each was designed at 2x and scaled down, so nothing is fuzzy. Later you upgrade the page to Premium: now the hero needs to be re-exported near 1464 wide, and you add a video at 1280 by 720. Same content, deliberately re-sized for the wider tier, and the page looks sharp at both.
That is the entire discipline: know the module, export to its size from a high-detail source, stay in RGB under the file limit, and re-export rather than stretch when you move tiers. Do that and sizing simply stops being a source of rejections and blur.
Tracking a dozen module dimensions per product is exactly the kind of fiddly work software should do. Our AI Product Photography and content tool outputs A+ imagery at the correct size for each module automatically.
Get the Amazon A+ content image size right at the source, and the rest of your design finally looks as good on the listing as it did in your head.

Start free →It depends on the module. A full-width image header is about 970 by 300 pixels, a tall header about 970 by 600, three-image cards about 300 by 300, and comparison columns about 150 by 300. Premium modules run wider, around 1464 pixels. Confirm the exact size in the upload window.
A+ images should be JPEG or PNG, in RGB color, and under 2 MB per image. Upload at the module's target dimensions or larger, and avoid animated formats.
Usually because they were uploaded below the module's native resolution and Amazon scaled them up, or compressed too hard to fit 2 MB. Export at the target size or a clean multiple of it, at high quality.
Yes. Premium modules are wider, roughly 1464 pixels for full-width formats, and video needs at least 1280 by 720. Basic modules top out around 970 pixels, so the same content needs different exports for each tier.
Match each module's dimensions, stay under 2 MB in RGB JPEG or PNG, and keep resolution high. Generating images at the correct size from the start avoids the resize-and-reject cycle.
