Every Amazon Image Size That Matters in 2026

Someone sent us a Premium A+ specification guide and asked whether it was still accurate. It was published in January 2024. We checked every dimension in it against three separate 2026 sources.

Almost all of them were still correct.

That is worth saying out loud, because the internet is full of guides with "2026" in the title that are the same numbers with a new date on top, and it is impossible to tell the diligent ones from the recycled ones by looking. So here is the working spec sheet, what genuinely moved, the handful of numbers people get wrong every time, and the three places where reputable sources still flatly contradict each other.

The A+ canvases, at true relative scale

Numbers in a table do not tell you how much bigger a Premium full-width module is than a standard A+ header. This does.

Premium A+, module by module

These held from the January 2024 guide through to the 2026 sources without moving. The desktop figure is what you export. The mobile figure is a separate upload, not a crop of the desktop file, and that is the single most expensive misunderstanding on this list.

Module	Desktop	Mobile
Full-width image	1464 × 600	600 × 450
Background with text	1464 × 600	600 × 450
Hotspots	1464 × 600	600 × 450
Navigation carousel	1464 × 600	600 × 450
Simple image carousel	1464 × 600	600 × 450
Comparison table, large	488 × 700	600 × 450
Single image with text	800 × 600	uses desktop
Dual images with text	650 × 350	uses desktop
Four images and text	300 × 225	uses desktop

Note the split in that last column. The wide modules want their own phone artwork. The smaller ones reuse the desktop file. That is not a rounding detail: it means a full Premium page is not nine exports, it is nine plus however many of them are full width, and a studio that quotes you for nine has not read the spec.

Standard A+, module by module

Module	Image size
Image header with text	970 × 600
Image header with text overlay	970 × 300
Company logo	600 × 180
Three images and text	300 × 300 each
Image beside text	300 × 300
Four images in a line	220 × 220 each
Four image quadrant	135 × 135 each
Comparison chart	150 × 300 each

Standard A+ uploads one asset per slot and lets Amazon scale and crop it for phones. Premium does not. That difference is most of the reason Premium looks better on mobile, and most of the reason it costs more to produce.

The gallery numbers, and the four that get misquoted

1000 pixels is a switch, not a suggestion. Below it on the longest side, Amazon does not enable zoom on that image. Zoom is the difference between a shopper being able to inspect a seam and having to guess. This is the most consequential number on the whole page and it is routinely written up as "recommended".

85 percent is the frame rule. The product must fill 85 percent or more of the main image frame. A catalogue photograph with polite breathing room around the subject fails this, and even when it passes review it reads as smaller and cheaper than the listing beside it.

Pure white means exactly RGB 255, 255, 255 on the main image. Not off-white, not a soft studio sweep that measures 252. And no text, logos, watermarks or inset images on the main image at all.

Nine allowed, seven shown. Most listings accept nine gallery images, but a desktop page displays seven by default. Slots eight and nine are real and they are also the ones nobody scrolls to, so put nothing load-bearing in them.

Two file-size ceilings, and they are different

This one costs people an afternoon.

Surface	Cap per image
A+ content, standard and Premium	2 MB
Gallery and main images	10 MB

Same brand, same product, same export session, two different limits. The A+ cap is the tighter one and it applies to Premium as well as standard, which surprises people who assume the premium tier gets premium headroom. It does not.

Formats are JPG or PNG for A+, with JPG preferred. Gallery accepts JPEG, PNG, TIFF and GIF, though animated GIFs are not allowed. Colour space is sRGB everywhere. A CMYK file will either be rejected or render with colours that are not the ones you approved.

The DPI thing is not real

You will see "72 DPI" in almost every guide, including current ones. DPI is a print instruction stored in the file header. A browser ignores it completely. An image that is 2000 pixels wide is 2000 pixels wide whether the header says 72, 300 or nothing at all.

It is harmless to set it and pointless to worry about it. What matters is the pixel count and the file size. If a supplier or a designer tells you an image failed because of DPI, that is not what happened.

Three places the specs genuinely disagree

Here is the part most guides leave out, and it is the part that actually bites.

Brand Story background. Quoted as 1464 × 625 and as 3000 × 600 by sources that are otherwise careful, with one noting the older size still works but displays smaller.

Brand Story card count. Quoted as four, as seven and as nineteen. One guide states outright that third-party sources conflict and tells you to check the builder.

A+ module counts per project. Several 2026 guides simply do not state a maximum, which is a more honest answer than the confident numbers elsewhere.

Our rule, and we would suggest it as yours: when the sources disagree, the A+ Content Manager upload screen is the only source that counts, and it is the one you check on the day you build. Amazon changes these without announcing them, and every guide on the internet including this one is a snapshot.

Eligibility has not moved either

Premium A+ still requires a published Brand Story on all brand-owned listings, plus at least five approved A+ content projects in the previous twelve months. Those are the same two conditions that were in the January 2024 guide, and they were being discussed in the Seller Central forums years before that.

It is free once you qualify. The cost is the sequencing: you cannot start with Premium, because qualifying for it requires having already shipped five standard A+ projects and a Brand Story. A brand that wants Premium in Q4 needed to start in Q2.

What to actually export

If you take one thing from this page, take the export list rather than the tables.

• Gallery and main images at 2000 × 2000, sRGB, under 10 MB, product filling 85 percent of the main frame on pure white.
• Standard A+ header at 970 × 600, under 2 MB.
• Premium full-width modules at 1464 × 600, plus a separate 600 × 450 phone version of each one.
• Check the smaller Premium modules against the table above rather than assuming, because they are the ones with odd sizes.
• Verify Brand Story in the builder on the day, because nobody agrees on it.

Everything else on this page is a number you can look up when you need it. Those five are the ones that decide whether the work you paid for arrives intact.
