Merchants keep asking for an Amazon image spec sheet, but the closest verified numbers available right now come from Shopify's own theme requirements and USPS package pricing, so this article lays out exactly what is confirmed rather than repeating unsourced numbers that circulate on forums.
A reader typing “amazon product image requirements” usually expects a pixel count, a background rule, and a file format, delivered as a tidy table. That table does not appear anywhere in the documents checked for this article, and no Amazon specification page was part of the measured set, so any number claiming to be Amazon’s rule here would be invented. What follows instead is a plain account of the requirements that were actually verified on September 9, 2026, drawn from Shopify’s Theme Store documentation and from USPS Notice 123, plus an honest statement of what is missing and why filling that gap with a remembered number would be worse than leaving it blank.
Shopify’s Theme Store requirements page, read on September 9, 2026, states an image size requirement of 64 x 64px required for certain theme store assets, alongside an aspect ratio requirement expressed as numeral to numeral rather than a fixed figure. This is a listing asset rule, meaning it governs images submitted to the Theme Store catalog, not photos a merchant uploads to a live product page. It is included here because it is the only pixel-precise, sourced image requirement available across the documents checked, and because a reader searching for Amazon’s rule deserves to see the difference between a sourced number and an assumed one. Nothing in the Shopify document extends this figure to Amazon, eBay, or any other marketplace.
The same Shopify document sets a minimum average Lighthouse performance score of 60 across the theme’s product, collection, and home page, checked for both desktop and mobile. This is a functional threshold rather than a visual one, and it applies before a theme can be listed at all. Alongside it sits a word count rule: word or character count capped at 32 words max for certain listing text, with a note that basic HTML formatting is allowed. These two rules, one performance-based and one content-based, sit closer to an official requirements table than any circulating pixel number for product photography, because both trace to a document with a URL and a checked date.
| Requirement | Value | Source document | Applies to |
|---|---|---|---|
| Image size | 64 x 64px required | Shopify Theme Store requirements | Theme Store listing assets |
| Lighthouse performance score | 60 minimum average | Shopify Theme Store requirements | Product, collection, home pages, desktop and mobile |
| Listing text length | 32 words max | Shopify Theme Store requirements | Text accompanying listing assets |
| 404 page content | Must state page wasn’t found | Shopify Theme Store requirements | Storefront error page |
USPS Notice 123, checked on September 9, 2026, lists a set of percentage adjustments tied to periodical mail classification rather than to package or image content. It states a nonadvertising adjustment factor for each of 1%, an authorized publications rate of 5%, and a single issue purchase rate of 90%. These figures are sometimes pulled out of context and applied to unrelated packaging or content discussions, but the notice itself ties them strictly to postage classification for periodicals. Including them here is a caution as much as a fact: a number being real and sourced does not mean it answers the question a reader is asking, and matching a number to the wrong question is exactly how bad requirements tables get built.
A real answer to “amazon product image requirements” needs a document from Amazon itself, read on a specific date, stating pixel dimensions, aspect ratio, background color rules, and file format limits, the same way the Shopify page states 64 x 64px required and a minimum average Lighthouse performance score of 60 for its own listing process. None of that Amazon-specific documentation was available among the measured facts used here, so none of it appears above as a number, and no placeholder figure was substituted in its place. The counts and figures presented instead were taken directly from Shopify’s Theme Store requirements page and from USPS Notice 123, both loaded and checked on September 9, 2026, and both cited with their exact wording rather than summarized into a rounder, less accurate number.
A merchant who needs Amazon’s actual image specification should go to Amazon’s own seller documentation and note the date it was read, treating any number without that kind of citation as unverified. Until that document is checked and its figures logged the same way the Shopify and USPS numbers were logged here, the honest answer to this search term is that the requirement exists somewhere but has not yet been measured for this article.
This article cannot state an Amazon pixel requirement because no Amazon specification appears in the measured facts used to build it. What is confirmed instead is Shopify's own Theme Store listing requirement, which sets a minimum of 64 x 64px required for certain theme store images. Merchants who need Amazon's own numbers should treat any figure not sourced to Amazon directly as unverified. Until a primary Amazon document is checked and dated, no pixel count should be trusted.
It does not directly, and this article does not claim it does. What it shows is the standard of documentation a reader should expect: a named file, a named requirement, and a checked date. Shopify's Theme Store requirements page states a minimum average Lighthouse performance score of 60 across product, collection, and home pages for both desktop and mobile, and that number is verifiable because it sits in a document anyone can load. The comparison exists to show what a real requirements table looks like versus a rumor.
USPS Notice 123 documents package pricing structures rather than image rules, but it does contain adjustment figures that are sometimes misquoted as content or size rules. The notice states a nonadvertising adjustment factor for each of 1%, an authorized publications rate of 5%, and a single issue purchase rate of 90%. These numbers concern periodical mailing classifications, not product photography, so they should not be mistaken for packaging or image dimension rules.
Treat the absence as the answer rather than filling it with a guessed number. This article only carries figures that trace to a named, dated document, and no such document about Amazon image pixel counts, background rules, or file formats was part of the measured set. A merchant needing that spec should pull it from Amazon's own seller documentation and note the date it was read, the same way this article notes September 9, 2026 for the Shopify page and the USPS notice.
Not directly, but it illustrates how granular real platform requirements get. Shopify's Theme Store requirements state that a 404 page must have a clear message stating that the page wasn't found, which is a content requirement, not a visual one. It is included here only to show the level of specificity a genuine requirements table contains, compared to vague pixel numbers that circulate without a source.
