Amazon image size & resolution requirements
Amazon's size rules sound simple — "at least 1000 pixels" — but the details decide whether your listing gets the zoom feature, looks sharp on a 4K screen, and survives Amazon's own re-compression. Here's exactly what the numbers mean and what to shoot for.
The 1000px zoom threshold
Amazon enables its hover/pinch zoom only when the longest side of an image is at least 1000px. Zoom is not a nicety — being able to inspect a product closely is a well-documented conversion driver, so an image under 1000px is quietly costing you sales even if it's technically "accepted." Below roughly 500px an image may not display properly at all.
In practice this makes 1000px the real minimum and anything smaller a mistake. The tool flags the longest side against this threshold so you know immediately whether zoom will turn on.
The 1600px sweet spot
Amazon's own guidance recommends around 1600px or larger. There are two reasons:
- High-density screens. A 1000px image looks soft when zoomed on a retina/4K display. 1600px+ gives real detail to zoom into.
- Re-compression headroom. Amazon re-encodes uploads. Starting from a larger, cleaner file means the compressed version buyers see still looks sharp.
The 10,000px ceiling
Amazon accepts images up to 10,000px on the longest side. You'll almost never need that, and enormous files upload slowly and get downscaled anyway. Somewhere between 1600px and 3000px is the practical range for most products.
Aspect ratio: shoot square
Amazon's search grid and thumbnails are square. A square (1:1) image displays fully without awkward cropping, and it keeps the product centred where the 85% fill rule expects it. A tall or wide image can be letterboxed or cropped in ways you didn't intend. When in doubt, export 1:1 — for example 1600×1600.
The DPI myth
You'll see "300 DPI" demanded all over seller forums. For a marketplace image displayed on screens, DPI is irrelevant. DPI (dots per inch) only describes how large an image prints on paper; it has no effect on how a browser renders it. A 1600×1600 file at "72 DPI" and the same file at "300 DPI" are pixel-for-pixel identical online. What matters is the pixel dimensions, full stop. Chasing a DPI number wastes time and sometimes leads people to shrink perfectly good images.
Upscaling doesn't create detail
If your only copy is 800px, enlarging it to 1600px in an editor adds pixels but not real detail — the result looks soft or mushy. Always export from the largest original you have. If the original is gone and the file is too small, reshooting beats upscaling. (ListingLint can resize for convenience, but no tool can invent detail that was never captured.)
File size and format
Keep the file a clean, high-quality JPEG for photos (PNG for graphics/transparency). Don't crush the quality to shrink the file — banding in a white background is a common result and can read as a non-uniform (non-255) background. More detail: JPEG vs PNG vs WebP for marketplaces.
Recommended export settings
- Dimensions: 1600×1600px square (bump to 2000–3000px for highly detailed products).
- Format: JPEG, high quality (around 80–90%), sRGB colour.
- Background: exactly 255,255,255 for the main image — verify, don't eyeball.
- Fill: product occupies ~85%+ of the frame with a small even margin.

Frequently asked questions
What is the minimum image size for Amazon?
1000px on the longest side to enable zoom; below ~500px an image may not display. Treat 1000px as the floor and 1600px as the target.
Does Amazon require 300 DPI?
No. DPI is a print concept and has no effect on on-screen listings. Only pixel dimensions matter. A 1600×1600 image is 1600×1600 regardless of its DPI tag.
Is a bigger image always better?
Up to a point. 1600–3000px is ideal. Beyond that you get slow uploads and Amazon downscales anyway, so there's little benefit to approaching the 10,000px ceiling.
