Amazon product image size and main image requirements (2026)

September 2026

For Amazon main product images, use a pure-white background (RGB 255,255,255) and at least 85% product fill without clipping the product. The longest side needs 1000 px for zoom; 1600 px or more is recommended. The zoom threshold is different from the upload minimum. The checklist below covers size, file format, background and framing.

This page lists the published main-image rules sellers actually hit, then shows how to check one real product image in the browser before Seller Central. Fernpix is an independent checker — Amazon still makes the final listing decision.

Amazon main-image spec (public seller help + Fernpix US ruleset)

RuleNumber to hit
Zoom threshold1000 px on the longest side turns on zoom
Recommended size1600 px or larger on the long side
Fernpix gate1000 px long side — stricter than Amazon's upload floor
File size≤ 10 MB
FormatJPEG preferred; PNG also accepted — not iPhone HEIC
BackgroundRGB 255,255,255 / #FFFFFF on the main image
Product fillAt least 85% of the frame; do not touch the edges
CenteringProduct near the center; leftover floor or halo still fails
Main-image extrasNo text, logos, borders, insets, or multiple views

What this checker can test automatically

  • Image width, height, and longest side
  • Square / aspect readiness for the selected marketplace
  • File format and file size
  • Measurable white-background, product fill, and crop-margin signals

What this checker cannot replace

  • Final marketplace approval
  • Category-, region-, or account-specific policy exceptions
  • Claims, trademarks, props, or text overlays (still need human review)
  • A guarantee that rules will not change

Where these numbers come from

Fernpix last read these sources on 2026-09-21. Not every number is a published platform rule. specs.json labels each one as a marketplace rule, a reported behaviour we could not confirm on a first-party page, or a stricter Fernpix default. See the labels

The three numbers Amazon actually enforces

Seller Central’s main-image gate is picky about pixel white and fill. A photo that “looks fine” on a laptop still rejects when the canvas is off-white or the product is small in frame. Resolution behaves differently: a 900 px file is usually accepted but loses the zoom viewer, which is why Fernpix gates at 1000 px anyway. Secondary and lifestyle images can show context; the main slot cannot.

Why the same file still gets rejected

Common misses: 250,250,250 studio sweep; cutout halo; shadow under the product; watermark or packshot text; product touching the edge; HEIC from an iPhone; a 4:3 phone shot that is tall enough but not 1000 px on the long side after crop. Recut to true #FFFFFF and re-check the export — compression can reintroduce a grey fringe.

Amazon vs Shopee / Lazada / TikTok Shop

Amazon wants a taller pixel floor (1000 / 1600) and ~85% fill. Shopee and Lazada want 1:1 squares with a ~2 MB cap. TikTok Shop tiles also crop to 1:1 with a looser 5 MB cap. Do not assume one export passes every marketplace.

Check locally before Seller Central

Drop the rejected main image into Fernpix’s Amazon profile. You will see which rule failed — white, fill, edges, dimensions, format, or file weight — then fix supported issues on this device. Catalog originals are not uploaded to Fernpix for the check.

Before you upload again

  • Longest side 1000 px so zoom turns on; 1600 px or more is better.
  • Background reads #FFFFFF, not warm paper or concrete grey.
  • Product fills about 85% and does not touch the edges.
  • JPEG or PNG only; convert HEIC first.
  • File under 10 MB after export, not before.
  • No text, logos, or extra products on the main image.

FAQ

What size does Amazon require for a main image?

Amazon turns on the zoom viewer at 1000 px on the longest side, and recommends 1600 px or more. Smaller files usually still upload, but Fernpix gates at 1000 px so a listing does not ship without zoom. JPEG or PNG, file under 10 MB.

What are Amazon main image requirements in 2026?

Same core numbers sellers hit every year: RGB 255,255,255 background on the main image, about 85% product fill without touching the edges, 1000 px long side for zoom (1600 px+ recommended), JPEG or PNG, file under 10 MB. Category extras and brand approval still sit in Seller Central.

Does Amazon require a pure white background?

Yes on the main image: RGB 255,255,255 (#FFFFFF). 250,250,250 studio grey, cream paper, a cutout halo, or a floor shadow still fail. Secondary images can use lifestyle scenes.

What is the 85% fill rule?

The product should fill about 85% of the frame and not touch the edges. A tiny product on a huge white canvas is a common reject even when the background is truly white.

Does a pass in Fernpix mean Amazon will approve the listing?

No. Fernpix checks published main-image numbers. Category exceptions, brand approval, and intellectual-property flags are still decided in Seller Central.
