Building Amazon A+ Content Modules: Every Dimension, Module by Module
Standard A+ image fields run from 135 x 135 for a quadrant image to 970 x 600 for the image header, with 300 x 300 the most common size and 150 x 300 per comparison-chart column. Premium modules are stated as minimums, typically 1464 x 600 for desktop and a separate 600 x 450 mobile asset for hotspots, carousels and full-width images — different aspect ratios, so a recomposition rather than a resize. Amazon publishes a sales lift of up to 8% for standard A+ and up to 20% for premium, both from internal data with no methodology.
Most A+ content is built at the wrong pixel dimensions, then quietly resampled by Amazon. The fix is boring and permanent: know the size of every module field before you open the canvas. Below are the dimensions Amazon publishes in its own standard and premium module template sheets, module by module, with the character limits that decide your copy and the separate mobile assets premium modules require.
What A+ is worth, in Amazon's own numbers
Amazon's guide for brand owners states that A+ content can improve conversion by around 5.6% and increase sales by up to 8%; for Premium A+ the published figure is a sales lift of up to 20% on average. Both are footnoted as Amazon internal data with no methodology, and Amazon notes results vary by content quality, price and category. An order of magnitude, not a forecast.
Access changed in May 2026: Premium A+ is now enabled by default for Brand Registry sellers rather than gated behind a sales threshold or an invitation. The conditions reported at the time were a published Brand Story on your brand-owned listings and five approved A+ modules in the previous twelve months. If Premium is greyed out in your account, that pair is the first thing to check.
Standard modules: every image field, with its size
These come from Amazon's standard module template sheet, which labels each image field with the dimension the uploader expects. Note how small they are: most of the grid is 300 px squares, not full-width art.
| Module | Image field(s) | Use it for |
|---|---|---|
| Company Logo | 600 × 180 | Brand line under the header |
| Image Header with Text | 970 × 600 | The opening banner |
| Image & Dark Text Overlay | 970 × 300 | Dark type over a light scene |
| Image & Light Text Overlay | 970 × 300 | Light type over a dark scene |
| Single Image & Sidebar | 300 × 400 main, 350 × 175 sidebar | Dense copy, two images |
| Single Left Image / Single Right Image | 300 × 300 | One benefit, alternating sides |
| Single Image & Highlights | 300 × 300 | One image, three subheaded blocks |
| Single Image & Specs Detail | 300 × 300 | Image plus structured specs |
| Three Images & Text | 300 × 300 each | Three features in a row |
| Four Images & Text | 200 × 200 each | Four features in a row |
| Four Images / Text Quadrant | 135 × 135 each | Four short points, 2 × 2 |
| Four Image Highlights | 400 × 400 lead image | Hero plus thumbnails |
| Comparison Chart | 150 × 300 per column, up to 6 | Your own range, side by side |
| Technical Specifications | No image | 4–16 name/value pairs |
| All Text | No image | Headline and body only |
Two consequences follow. A 135 × 135 quadrant image cannot carry a caption inside the artwork — put those words in the module's headline and body fields, which are text, not pixels. And the comparison chart's 150 × 300 columns are portrait, so a square product shot is letterboxed unless you re-crop. Seller Central states the requirement in the upload window for the module you selected; that window is the authority.
Premium modules: bigger canvases, and a second set of files
Premium modules are specified as minimums rather than fixed sizes, and several need a separate mobile asset. Amazon's premium template sheet is explicit: for hotspots and carousels you supply one image per panel or hotspot for desktop and another for mobile.
| Premium module | Desktop image (min) | Mobile image (min) | Limits |
|---|---|---|---|
| Image with Text | 800 × 600 | Uses desktop asset | Sub 40, head 80, body 500 chars |
| Background Image with Text | 1464 × 600 | 600 × 450 | Sub 40, head 60, body 300 |
| Dual Images with Text | 650 × 350 | Uses desktop asset | Sub 50, head 50, body 300 |
| Four Images with Text | 300 × 225 | Uses desktop asset | Module head 80, image head 30, body 150 |
| Full Image with Optional Text | 1464 × 600 | 600 × 450 | Head 80, body 300 |
| Comparison Table 1 | 200 × 225 | Uses desktop asset | 4–7 products, 5–12 features |
| Comparison Table 2 | 300 × 225 | Uses desktop asset | 2–3 products, 2–5 features |
| Comparison Table 3 | 488 × 700 | 600 × 450 per panel | 2–4 products, 3–7 features |
| Hotspots 1 and 2 | 1464 × 600 | 600 × 450 per hotspot | 2–6 hotspots; tooltip body 200 |
| Image Carousel with CTA | 1464 × 600 | 600 × 450 per panel | 2–6 panels; head 50, body 200 |
| Navigation Carousel | 1464 × 600 per panel | 600 × 450 per panel | 2–5 panels; body 100 |
| Regimen Carousel | 1464 × 600 | 600 × 450 per panel | 2–5 panels; inset body 100 |
| Video with Text | 800 × 600 video and preview | Uses desktop asset | Head 80, body 500 |
| Full Video with Optional Text | 1464 × 600 video and preview | Uses desktop asset | Head 80, body 300 |
1464 × 600 and 600 × 450 are different aspect ratios: 2.44:1 against 4:3. That is not a resize, it is a recomposition, and it is the commonest reason a premium carousel looks superb on desktop and clips the product on a phone. Design the mobile crop deliberately.
Brand Story sits above the A+ block as its own carousel. The figure most commonly cited for its background is 1464 × 625, though some 2026 guides now recommend a much wider hero asset. Sources genuinely disagree, so take this one from your own upload window rather than from any article, including this one.
Which modules earn their slot
The set is generous and the temptation is to use all of it. A tighter rule:
- Comparison Chart is the highest-value standard module in any range with more than one SKU: it answers "is this the right version for me" and keeps the click inside your catalogue.
- Technical Specifications costs no design time and is pure structured text, the format Amazon's own systems parse most easily.
- Four Images / Text Quadrant at 135 × 135 is the weakest. At that size an image is a pictogram, not a photograph. Use it for icons or not at all.
- Premium hotspots repay the work only where the product has parts to point at. Elsewhere they are decoration costing two files per hotspot.
Keeping A+ consistent with the gallery
A+ and the gallery are read seconds apart by the same person, so the failure mode is not ugliness but discontinuity: a benefit phrased one way in image four and another in the A+ header. Fix vocabulary first, styling second. Lift the claims from your gallery images verbatim into the A+ headlines, keep one typeface and one accent colour across both, and reuse the gallery's product angle in the A+ hero so the reader recognises the object rather than re-parsing it.
Where they must differ: the gallery has to survive a thumbnail, A+ never does. A+ is read at full width by someone already committed to scrolling, so it can carry longer copy and finer type than any gallery image should.
Where to start today
With no A+ at all, publish three standard modules — Image Header with Text, Comparison Chart, Technical Specifications — and stop. That covers the header, the range and the specs with one designed asset. If Premium is unlocked, the first upgrade worth making is replacing the header with Full Image with Optional Text at 1464 × 600: one asset, one mobile crop, and the module the shopper actually sees. Leave carousels and hotspots until the copy is settled, since every edit multiplies across panels.
Common questions
What size should A+ content images be?
There is no single size. Standard modules run from 135 × 135 for a quadrant image to 970 × 600 for the image header, with 300 × 300 the most common field. Premium modules are minimums, commonly 1464 × 600 for full-width desktop assets and 600 × 450 for their mobile counterparts. Seller Central's upload window states the requirement for the module you selected.
Do premium A+ modules need separate mobile images?
Several do. Amazon's premium template sheet specifies a mobile image of at least 600 × 450 per panel or hotspot for the hotspot modules, the image, navigation and regimen carousels, background image with text, full image with optional text, and comparison table 3. The rest reuse the desktop asset.
Is Premium A+ content free?
Since May 2026 Premium A+ has been enabled by default for Brand Registry sellers rather than sold or granted by invitation. The conditions reported at the time were a published Brand Story across your brand-owned listings and five approved A+ modules in the past twelve months.
How much does A+ content actually lift sales?
Amazon publishes roughly 5.6% better conversion and up to 8% more sales for standard A+, and up to 20% on average for Premium A+. Both come from Amazon internal data with no published methodology, and Amazon states results vary by quality, price and category.
