Most sellers spend weeks perfecting their seven main listing images, then treat A+ Content as an afterthought: a few leftover photos dropped into whatever module looks nice. That is a mistake. A+ Content sits below the fold on your detail page, where shoppers land when they are already interested but not yet convinced. It is the part of the listing that closes the sale, and it plays by a completely different set of image rules from your main gallery.

Those rules trip people up constantly. The dimensions are module-specific, the file size ceiling is lower than most people expect, and Amazon rejects submissions for content that would be perfectly legal in your bullet points. Here is what actually applies in 2026, and how to prepare images that pass on the first attempt.

A+ Content is not the same as your main image gallery

Your main gallery images live under strict marketplace rules: pure white background on the hero shot, product filling at least 85 per cent of the frame, 1600 px on the longest side to enable zoom. A+ Content has none of those constraints. You can use lifestyle scenes, coloured backgrounds, diagrams, text overlays, and comparison tables.

What you gain in creative freedom you pay for in technical specificity. Every gallery image follows one spec. Every A+ module follows its own.

Who can use it

A+ Content is gated on Brand Registry, not on fulfilment method. If your brand is registered, both FBA and FBM sellers can publish Standard A+ on the ASINs they own, at no cost. Premium A+ — which unlocks carousels, hover hotspots, larger images and inline video — was historically a paid tier. Amazon has since opened it to Brand Registry sellers for free, subject to a gate: you generally need a published Brand Story and around five approved A+ projects in the trailing 12 months. That threshold has moved before, so check your own eligibility in Seller Central rather than trusting any blog post, including this one.

The file specs that apply to every module

Before dimensions, get the fundamentals right. These apply across the board:

The 2 MB ceiling deserves emphasis. It is a hard limit, but treating it as a target is a mistake. A 1.9 MB banner is a slow banner, and A+ Content sits below the fold where a large share of your traffic is on mobile data. Aim well under 500 KB per image. A well-compressed JPEG at 970 px wide should comfortably land between 100 and 300 KB with no visible quality loss. Use JPEG for photographs and PNG for graphics with flat colour and hard edges, such as icons and diagrams.

Standard module dimensions

Standard A+ is built around a 970 px content width on desktop. Here are the module sizes you will use most often:

ModuleImage size (px)ImagesTypical use
Company Logo600 x 1801Brand mark at the top
Image Header with Text970 x 6001Hero banner, opening statement
Image and Text Overlay / banner970 x 3001Section break, wide feature strip
Three Images and Text300 x 3003Three key benefits side by side
Four Images and Text220 x 2204Four features in a row
Four Image Quadrant135 x 1354Compact icon grid
Comparison Chart150 x 300Up to 6Comparing your own product range
Premium Full-Width Image1464 x 6001Premium A+ only

One important caveat: these are the sizes in common use, but Amazon adjusts module specs periodically and templates vary slightly by marketplace. The upload window in Seller Central always displays the exact pixel requirement for the module you have selected. That window is the authority. Check it before you batch-export forty images to the wrong size.

Design for mobile, not for your monitor

The majority of Amazon traffic is mobile, and A+ modules reflow on small screens. A three-image row that reads beautifully on desktop stacks vertically on a phone, so the left-to-right logic you designed disappears and the order becomes top-to-bottom. Sequence your images accordingly.

Text overlaid on images is where most A+ Content fails in practice. It looks crisp in Photoshop at 100 per cent and becomes unreadable at phone width. Two rules help: keep overlay text at a minimum of roughly 24 px in your source file, and design at 2x scale then export down, so text survives on high-density displays. Keep text at least 50 px from the edges, and avoid placing faces or critical text in the bottom 20 per cent of a 970 x 600 header — Amazon sometimes overlays interface elements there depending on device.

Resizing a set of source images into eight different module dimensions by hand is exactly the kind of repetitive work that eats an afternoon. If you are preparing A+ modules alongside gallery images for several marketplaces, a batch tool such as PixelPrep will handle the resizing and compression in one pass, so you can focus on the layout rather than the export dialog.

The rejection traps: what you cannot say

Image specs cause a large share of A+ rejections. Prohibited content causes most of the rest, and it catches experienced sellers because these rules are stricter than the ones governing your title and bullets. You may not include:

Claims need substantiation. Awards should carry a date and the certifying organisation, and anything older than two years is best removed. Health and environmental claims attract particular scrutiny.

One further trap: reusing images that already appear in another submission under review can cause a rejection. If you are rolling out A+ across a range, vary the assets rather than pasting the same banner into every ASIN.

Does A+ Content help SEO?

Partly, and not in the way most people assume. Amazon's own search algorithm gives your title and backend keywords the ranking weight; A+ body text is not the lever people imagine it to be. What A+ text does do is get indexed by Google, which matters for external traffic to your detail page. The real value of A+ is conversion: it answers objections at the moment the shopper is deciding. Write it for the human, and treat the Google indexing as a bonus.

Pre-flight checklist

  1. Confirm the exact module dimension in the Seller Central upload window before exporting.
  2. Export as JPEG or PNG, in RGB, never CMYK.
  3. Compress to under 500 KB per image, well inside the 2 MB limit.
  4. Design at 2x scale, keep overlay text at 24 px or larger, and stay 50 px from the edges.
  5. Keep faces and key text out of the bottom 20 per cent of the 970 x 600 header.
  6. Sequence multi-image modules for vertical stacking on mobile.
  7. Strip out every mention of price, shipping, warranty, reviews, competitors and time-sensitive words.
  8. Remove trademark and registration symbols from customer-facing text.
  9. Date and attribute any award or claim; delete anything over two years old.
  10. View the draft on a phone before submitting, not just on your desktop.

Get the specs right once and build a template. The modules do not change often, and a set of correctly sized, correctly compressed source files turns each new product launch into a half-hour job instead of a two-day one.
