Amazon A+ Content sizes are set per module, not per page, which is the thing that trips up most
first attempts. There is no single canvas dimension. Each module you add expects its own image
dimensions, and supplying the wrong ones produces either a rejected upload or a visibly cropped
image.
Read this before designing anything: the A+ builder in Seller Central displays the exact required
dimensions for each module at the moment you add it, and that display is the authoritative source.
Amazon revises module specifications, and it does so without announcement. The table below reflects
the dimensions these modules have commonly required, and it is a planning reference rather than a
substitute for checking the builder.
That caveat is not a hedge. I’ve seen a full design set produced against a figure from a blog post and
then need reworking, and it costs more than the 5 minutes checking would have taken.
Standard A+ Content module sizes
| Module | Commonly required image size (px) |
|---|---|
| Standard Company Logo | 600 × 180 |
| Standard Image Header with Text | 970 × 600 |
| Standard Image & Light Text Overlay | 970 × 300 |
| Standard Image & Dark Text Overlay | 970 × 300 |
| Standard Single Image & Sidebar | 300 × 400 main, 350 × 175 sidebar |
| Standard Single Left/Right Image | 300 × 300 |
| Standard Three Images & Text | 300 × 300 each |
| Standard Four Image & Text | 220 × 220 each |
| Standard Four Image & Text Quadrant | 135 × 135 each |
| Standard Comparison Chart | 150 × 300 per product |
| Standard Product Description Text | no image |
| Standard Technical Specifications | no image |
| Standard Multiple Image Module A | 300 × 300 each |
The two text-only modules are worth noticing. Standard Product Description Text and Technical
Specifications need no images at all, and in our experience they are the most underused modules in
the set, because everyone reaches for the visual ones first.
Premium A+ Content module sizes
Premium A+ is a larger, richer format with interactive and video modules, available to brands meeting
Amazon’s eligibility criteria.
| Module type | Commonly required size (px) |
|---|---|
| Premium full-width image modules | 1464 × 600 |
| Premium video modules | 1920 × 1080 |
| Premium comparison and hotspot modules | varies by layout |
Premium expects assets roughly 50% wider than standard, which is the practical planning point. If
there is any prospect of qualifying for Premium later, shoot and design at the larger size now and
downscale for standard. Upscaling afterward does not work, and redoing photography does.
General image and file requirements
These change less often than module dimensions, but confirm them in the builder too.
- Formats: JPG, PNG, or BMP. PNG for anything with text or flat graphics, JPG for photography. When I have compared the two on the same asset, the difference on flat graphics was obvious and on photographs was invisible.
- File size: keep each image under 2 MB. Smaller files load faster and Amazon compresses anyway.
- Resolution: 72 dpi is sufficient. This is a screen medium, and 300 dpi assets simply produce a
larger file for no visible gain. - Color mode: RGB, not CMYK. A CMYK file either fails or shifts color unpredictably.
- No text in the image where you can avoid it. More on this below, because it is the single most
consequential rule on the page.
The two rules that cause most rejections
1. Text baked into images is a trap
Amazon allows text within A+ images, and it is still usually the wrong choice.
It is not read by screen readers, which is an accessibility problem and, on some marketplaces, a
compliance one. It does not resize well on a phone, where most of your traffic is. And it cannot
be edited without regenerating the asset, so a price change or a claim update means going back to a
designer.
Use the module’s own text fields instead. They are responsive, editable, accessible, and they cost
nothing. I’d bake text into an image only when it is genuinely part of the design, such as a label on
a product diagram.
2. Mobile crops differently from desktop
A+ modules reflow on mobile, and the crop is not always what the desktop preview suggests.
Keep the important content in the middle of the frame. Logos, faces, and key product detail sitting near an edge are precisely the elements that vanish when a module reflows into a narrower column, because the crop takes from the sides rather than scaling the whole image down proportionally the way a designer intuitively expects it to. Edges disappear. Centers survive. In our experience this is the most common reason a design
that looked correct in review looks wrong on a phone, and the preview toggle in the builder catches it
in seconds.
Which modules are actually worth using
Dimensions are the easy part. Choosing modules is where the value sits, and most A+ content uses too
many of them.
A comparison chart is the highest-value module for most brands. It keeps a shopper inside your
range rather than sending them back to search, and it is the module that most directly affects which
of your products they buy.
One strong header image establishes the brand. Two competing header modules dilute it, and I’d cut the weaker one rather than keep both.
Three or four modules total is usually enough. A long scroll of images gets skimmed, and the
modules at the bottom are seen by very few people.
Text modules carry the specifications that answer the questions your reviews keep raising. Cheap to produce, easy to update, and better for accessibility than an image of a table. In our experience they also survive Amazon’s layout changes better, because there is no image to re-crop.
I’d build A+ around the three objections that cost you the most sales, and stop there. When I have
audited underperforming A+ content, the problem was almost never image quality. It was that the content
answered questions nobody was asking.
Why the dimensions keep changing
Worth explaining, because it is the reason this page carries a caveat that most do not.
Amazon has rebuilt the A+ experience several times, and in our experience each rebuild left a trail of outdated advice behind it. Enhanced Brand Content became A+ Content. A+ gained
a Premium tier. Modules have been retired, renamed, and re-specified, and the mobile layout has been
revised repeatedly as phone traffic grew from a minority to the majority of detail-page views.
Each of those changes altered what the builder expects. Published dimension lists therefore rot
quickly, and the internet is full of confidently stated figures that were accurate in a year nobody
mentions. When I have chased a mismatch between a design brief and a rejected upload, an out-of-date
reference was the cause more often than a designer error.
Three habits that survive the churn:
- Shoot at generous resolution and crop down. A 2000 pixel wide original serves every module that
exists now and most of what replaces them. - Keep the layered source files. Re-cropping a PSD takes minutes; recreating a flattened JPG takes
a day. - Design for a 4 inch screen, then check the desktop. The reverse order is how the mobile problems
happen.
What A+ Content actually does for a listing
Briefly, because the specifications are pointless without the purpose.
A+ Content replaces the plain product description with a formatted section further down the detail page. Simple change. Large consequences. It is below the fold, which means it is read by shoppers who are already interested rather
than by everyone. That single fact should shape what you put there.
Those readers are looking for a reason to be reassured or a reason to buy the other model. Answer both.
Specifications, sizing, compatibility, what is in the box, and how your range differs internally are
what they came for. Brand storytelling is what most A+ content gives them instead. In our experience that mismatch explains why so much of it makes no measurable difference, and I’d fix the mismatch before touching a single dimension. A page that answers the wrong questions beautifully still answers the wrong questions.
Getting the specs right, every time
A short workflow that avoids rework:
- Open the A+ builder and add your intended modules first, before any design work.
- Note the dimensions the builder states for each one you have added.
- Design against those numbers, at the Premium size if Premium is a realistic prospect.
- Preview on mobile and desktop inside the builder before submitting.
- Submit and expect a review period. Rejections usually name the reason, and I’ve found reading it properly is most of the fix. People resubmit before reading, then resubmit again.

FAQ
What are the Amazon A+ Content image sizes?
Sizes are set per module rather than per page. Common requirements include 600 × 180 for the company
logo, 970 × 600 for an image header with text, 970 × 300 for text-overlay modules, and 300 × 300 for
standard image modules. The A+ builder states the exact requirement for each module as you add it.
What size are Premium A+ Content images?
Premium modules commonly expect 1464 × 600 for full-width images and 1920 × 1080 for video, roughly
50% wider than standard. If Premium eligibility is a realistic prospect, design at the larger size and
downscale, because upscaling later does not work.
What file formats does Amazon A+ Content accept?
JPG, PNG, and BMP, in RGB rather than CMYK, at 72 dpi, with each file kept under 2 MB. PNG suits text
and flat graphics; JPG suits photography.
Should I put text inside A+ Content images?
Usually not. Image text is not read by screen readers, does not resize well on mobile, and cannot be
edited without regenerating the asset. The module’s own text fields are responsive, editable, and
accessible, and they cost nothing.
Why does my A+ Content look wrong on mobile?
Because modules reflow on mobile and crop differently from the desktop preview. Keep logos, faces, and
key product detail toward the middle of the frame, and use the builder’s preview toggle before
submitting.
How many A+ modules should I use?
Three or four is usually enough. Long module stacks get skimmed and the lower ones are seen by very few
shoppers. A comparison chart plus one strong header and one or two text modules covers most brands
better than a full set.
Last updated: August 30, 2026. Amazon revises A+ Content module specifications without notice. The
dimensions here reflect what these modules have commonly required and are a planning reference only;
the A+ builder in Seller Central displays the current requirement for each module and is the
authoritative source.
