Every A+ module has fixed image dimensions, and Seller Central rejects files that don't match. If you're briefing a designer — or building modules yourself — these are the numbers that matter in 2026.
Standard A+ Content sizes
Standard A+ modules are built on a 970 px-wide grid. The sizes you'll use most:
| Module | Image size (px) |
|---|---|
| Company logo | 600 × 180 |
| Image header with text | 970 × 600 |
| Full-width banner | 970 × 300 |
| Four-image highlight | 300 × 300 each |
| Single image & sidebar details | 300 × 400 area |
| Comparison chart product images | 150 × 300 each |
A standard A+ page can use up to 7 modules. You don't need all of them — a strong page typically runs a hero banner, two or three benefit/ingredient modules, a how-to sequence, and a comparison chart that cross-sells your catalogue.
Premium A+ Content (A++) sizes
Premium A+ replaces the 970 px grid with full-width 1464 px modules — plus carousels, hotspot images, video modules, and richer comparison tables. Common canvases include full-width banners around 1464 × 600 px and carousel slides at Premium's larger frame sizes.
The design implication: Premium A+ isn't "standard A+ but stretched." Layouts, type sizes, and image crops need to be designed for the wider frame, or the page looks inflated rather than premium.
Brand Story sizes
The Brand Story (the "From the brand" carousel) uses its own canvas:
- Background hero: 1464 × 625 px (desktop), with a separate 463 × 625 px mobile crop
- Carousel cards (about-the-brand, product highlight, media cards) in Amazon's fixed card frames
Because the background and the cards scroll together, the safest approach is designing the whole story as one continuous scene, then exporting to the individual frames.
File rules that prevent upload errors
- Format: JPEG or PNG, sRGB color
- File size: keep each image comfortably under Amazon's per-file limits (a few MB) — enormous exports get rejected or compressed badly
- Text in images: keep it large; modules are shrunk dramatically on mobile, and most Amazon traffic is mobile
- No pricing, promo claims, or competitor references in A+ imagery — Amazon rejects these at review
The mobile check most pages skip
Amazon renders A+ modules at phone width by stacking and scaling them. A 970 × 300 banner with 24 px text becomes unreadable at 375 px wide. Before uploading anything, preview every module at mobile width — or work with a designer who designs mobile-first by default.
If you'd rather hand the whole thing off: I design complete A+ pages — standard and Premium — delivered upload-ready at exactly these specs.
