Amazon Product Image Size Requirements: The Complete Spec Guide

Amazon product image size requirements, in one line: upload at least 1,000 pixels on the longest side to enable zoom, ship 1,600–2,000px as the working standard, keep the main image on a pure white background (RGB 255,255,255) with the product filling 85%+ of a 1:1 square frame, and save as a JPEG under 10MB. Everything else on this page is the detail behind that sentence — the full spec table, the main-image rules that get listings suppressed when broken, and the six rejection causes that account for almost every “image failed to upload” ticket.

Most guides that answer “what size should Amazon listing images be” give you a single number and move on. That number — 1,000px — is real, but it is the floor, not the target, and it is the reason so many listings have quietly dead zoom. Below is the version a seller actually needs: the whole spec, what each rule is enforced for, and how to check your live files against it.

How these numbers were verified. The specs below were cross-checked on 2026-07-17 against multiple current industry references. Amazon’s own Seller Central spec page (Product image requirements, help reference G1881) sits behind a seller login and is not publicly fetchable, so where independent sources disagreed on a value — mainly the recommended dimension and the exact file-size ceiling — the range is noted rather than a single number stated as gospel. Amazon can revise these; re-check before a major reshoot.

The Complete Amazon Image Spec (Quick Reference)

Two numbers on this table do more work than the rest combined: the 1,000px zoom threshold and the 85% frame fill on the main image. Miss the first and you disable your highest-converting gallery interaction. Miss the second and Amazon’s image classifier may suppress the listing outright. The following sections take them in that order.

Size and Resolution: Why 1,000px Is a Floor, Not a Target

Amazon technically accepts a main image as small as 500px on the longest side. It should not be anywhere near your target, for one mechanical reason: zoom only activates at 1,000px on the longest side. Below that, the image uploads cleanly, shows on the page, and looks fine in the seller dashboard — but the magnifier that appears when a shopper hovers is silently switched off. There is no error, no warning, no flag in your listing quality report. The feature is just dead.

That matters because zoom is one of the highest-intent interactions on a product page. A shopper who hovers to inspect stitching, a port, or a texture is a shopper close to buying. Handing them a dead magnifier is a conversion leak you cannot see from the seller side.

So the practical hierarchy is:

• 500px — the absolute minimum Amazon will accept. Never ship this deliberately.
• 1,000px — the line where zoom turns on. The real minimum for any serious listing.
• 1,600–2,000px — the working standard. Reliable zoom, crisp on high-DPI screens, and headroom for Amazon’s own recompression.
• Up to 3,000px — worth it for detail-heavy categories (apparel texture, jewelry, electronics ports) where shoppers zoom aggressively.
• 10,000px — the ceiling. Images larger than this on the longest side are rejected.

The 1:1 square aspect ratio applies to the main image specifically. Square framing is what keeps the product centered and consistently sized against the grid of competitors in search results — and it is the shape the thumbnail is cropped to whether you supply it or not.

A subtle trap here: the resolution you uploaded and the resolution Amazon serves back on the page are two different things. The live page renders a compressed 500–700px derivative, so eyeballing your own listing tells you nothing about whether the underlying file is 900px or 2,000px. The only way to know is to check the actual stored file — which is exactly what the image download guide walks through at the URL level.

File Format, Color, and File Size

Format. Amazon accepts JPEG (.jpg), PNG (.png), TIFF (.tif), and non-animated GIF (.gif). JPEG is the preferred and by far the most common choice: it compresses photographic product shots well and is what Amazon’s pipeline is tuned for. Reach for PNG only when you genuinely need lossless edges (rare for photography, sometimes useful for infographic PT slots with sharp text). Animated GIFs are rejected — the animation is stripped or the upload fails.

Color mode. Export in sRGB. It is the color space browsers and Amazon’s rendering assume, so an sRGB file is what a shopper actually sees. (CMYK has historically been accepted by the upload pipeline, but designing in CMYK invites color shifts on screen — stay in sRGB unless you have a specific print-adjacent reason not to.)

File size. Keep each file under 10MB. In practice a well-exported 2,000px JPEG lands well below that — often a few hundred KB to 2MB — so the ceiling is rarely a constraint unless you are uploading uncompressed TIFFs. Do not confuse “under 10MB” (the hard limit) with “as large as possible”: a bloated file gets recompressed anyway and only slows your own upload.

File naming. Amazon expects a product identifier followed by the slot and extension — an ASIN, UPC, EAN, JAN, or ISBN, then the image role. A compliant main-image name looks like B000123456.MAIN.jpg; secondary slots use .PT01, .PT02, and so on. This matters mostly for bulk/flat-file uploads and image-only feeds; the Seller Central drag-and-drop uploader is more forgiving, but consistent naming is what keeps a large catalog auditable.

Main Image Rules: The Ones That Get Listings Suppressed

The gallery slots (PT01–PT08) are creatively open — lifestyle, infographics, scale shots, comparison charts. The main image is not. It is governed by a strict, mechanically enforced ruleset, because it is the single asset Amazon shows in search results and the one buyers judge first. Break these and the outcome is not a polite note; it is suppression or an auto-reject.

• Pure white background — RGB 255,255,255. Not off-white, not light grey, not a soft studio gradient. Amazon’s classifier checks the actual pixel values; a background that reads as 250,250,250 can get flagged. The standard production move is to knock the background to true white in editing rather than trusting the lighting.
• Product fills ≥ 85% of the frame. The product must dominate the square. Too much white margin and the item looks small and loses thumbnail impact; the 85% rule is both a compliance line and a CTR lever. (This exact test — resize your main to 160px and check frame fill against competitors — is checkpoint #2 in the listing image audit checklist .)
• The actual product only. A real photograph of the item being sold — no renderings, illustrations, placeholders, or mockups on the main image.
• Nothing added on top. No text, logos, watermarks, borders, colored backgrounds, badges (“Best Seller”, “100% Natural”), or inset/callout images. This is the most-violated rule, usually because a well-meaning designer adds a “Top Rated” flash to the hero.
• No extra props or accessories that are not part of what the buyer receives. If the bundle does not include the staging bowl, the bowl cannot be in the main image.

The recurring theme: the main image is an identification shot, not a marketing canvas. Save the selling for the gallery.

Secondary Images, A+ Content, and Slot Count

Beyond the main image, a listing carries up to 9 images total, of which 7 display by default on desktop before a shopper clicks to expand. Because slots 8 and 9 are hidden by default, the sequencing rule is simple: put your strongest, objection-answering images in the first seven, and treat the last two as bonus depth rather than prime real estate.

Secondary slots (PT01–PT08) drop the white-background and text restrictions — this is where infographics, scale references, lifestyle scenes, and comparison charts live. They still inherit the size, format, and file-size specs from the table above: ship them at 1,600px+ so their zoom works too, and keep infographic text legible on a 375px-wide phone, since mobile is where most of the gallery is actually viewed.

A+ Content modules are a separate system with their own module-specific dimensions (Brand Registry required, image widths defined per module template rather than by the catalog spec above), and they are served from a different host entirely. If you are exporting a listing to study its full visual footprint, the A+ images will not appear in the main image feed — a tool has to scan the A+ DOM region separately, which is covered in the download guide .

The Six Most Common Rejection (and Dead-Zoom) Causes

Almost every “my image won’t upload” or “why is zoom not working” case traces to one of these:

1. Under 1,000px on the longest side → uploads, but zoom is silently disabled. Under 500px → rejected outright.
2. Text, logo, watermark, or border on the main image → auto-rejected by the classifier.
3. Background not pure white (RGB ≠ 255,255,255) → flagged; off-white and shadowed backgrounds are the usual culprits.
4. Product fills less than 85% of the frame → auto-detected; the listing looks weak even when it slips through.
5. Unsupported format or an animated GIF → rejected; convert to JPEG.
6. A rendering, illustration, or placeholder instead of a real photo on the main image → rejected.

Fixing the size (cause 1) and the background (cause 3) clears the large majority of real-world rejections. If an upload keeps failing after those two are correct, work down the rest of the list in order.

The Workflow: Research the Category, Then Produce to Spec

Knowing the spec is half the job. The other half is producing images that both pass the spec and win the category — and that starts with seeing what the top listings in your niche actually do, then shooting your own assets to match the bar.

A repeatable loop:

1. Study the category’s images at full resolution. Pull the galleries of your top 5–10 competitors so you can see their true main-image framing, how many of the 7 default slots they fill, their infographic density, and where their scale shots sit. The systematic version of this is the competitor image analysis workflow .
2. Read the numbers off the real files, not the page. Because the live page only serves a compressed derivative, the way to know a competitor’s true upload resolution — and to spot where they are cutting corners — is to inspect the exported files. This is where a one-click bulk export earns its place: ASINCrate pulls every image at original resolution, foldered by variant and named by slot, so you can verify dimensions and format on the actual assets instead of guessing.
3. Shoot or design your own images to the spec above. Main image at 2,000px, 1:1, pure white, 85%+ fill; gallery slots at 1,600px+ with mobile-legible text.
4. Verify your own live files after upload. Re-export your own listing and confirm Amazon is serving what you uploaded — the same check catches a silently downscaled hero before it costs you zoom.

One hard line runs through the whole loop, and it is the same standard this site holds everywhere: study competitor images, never reuse them. Researching a rival’s framing, slot order, and infographic strategy is ordinary market research. Copying a competitor’s actual image file into your own listing is copyright infringement that Amazon actively enforces. The workflow above never requires reusing a single competitor asset — only learning from the strategy behind it, then producing your own to the spec.

Frequently Asked Questions

What size should Amazon listing images be?

At least 1,000 pixels on the longest side, which is the threshold that activates zoom. The working standard is 1,600–2,000px (up to 3,000px), with 1:1 square framing. Amazon will accept images down to 500px on the longest side, but anything under 1,000px silently disables zoom, and the maximum is 10,000px.

What is the minimum image size for Amazon zoom?

Zoom activates when the longest side is at least 1,000 pixels (1000×1000). Below that the image uploads but the zoom feature is disabled with no warning. Because zoom is one of the highest-converting gallery interactions, 1,600–2,000px is the practical minimum sellers should ship.

What file format and color mode does Amazon require for product images?

JPEG (.jpg) is preferred; PNG (.png), TIFF (.tif) and non-animated GIF (.gif) are also accepted. Images should be in the sRGB color space (CMYK has historically been accepted too), and each file should stay under 10MB.

What are the main image requirements on Amazon?

The main image must be a pure white background (RGB 255,255,255) with the actual product filling at least 85% of the frame. No text, logos, watermarks, borders, badges, or props and accessories that are not part of the purchase. It must be a real photo of the product, not a rendering, illustration or placeholder.

How many images can you add to an Amazon listing?

Most categories allow up to 9 images per listing, but only 7 display by default on desktop before the shopper clicks to expand. Because slots 8 and 9 are hidden by default, put your strongest images in the first 7 and treat the last two as bonus depth.

Why did Amazon reject my product image or disable zoom?

The six most common causes: the file is under 1,000px on the longest side (no zoom) or under 500px (rejected outright); the main image has text, a logo, a watermark or a border; the background is not pure white RGB 255,255,255; the product fills less than 85% of the frame; the file is an unsupported format or an animated GIF; or the image is a rendering rather than a real photo. Fixing the size and background issues clears most rejections.

Conclusion

The spec itself is short: 1,000px to enable zoom (1,600–2,000px to do it well), 1:1 square, JPEG under 10MB in sRGB, up to 9 images, and a main image that is nothing but the real product on pure white filling 85% of the frame. The mistakes are equally predictable — a hero under 1,000px with dead zoom, an off-white background, a “Best Seller” badge that suppresses the listing.

The discipline that prevents all of them is looking at your actual files, not the flattering on-page preview. Export your live gallery, confirm every image clears the table above, and benchmark the result against the category with the competitor image analysis workflow and the 12-point image audit . Meeting the spec is table stakes; the next rank position belongs to whoever meets it and reads the category best.
