Quick reference: product image sizes by platform
Use this table as your cheat sheet. Dimensions are the recommended values that display sharply on modern high-resolution screens; the "minimum" column is the smallest size the platform accepts before quality or features (like zoom) break.
| Platform | Recommended size | Aspect ratio | Format |
|---|---|---|---|
| Amazon (main image) | 1,600 × 1,600 px (min 1,000 px for zoom) | 1:1 | JPEG (preferred) |
| Shopify (product) | 2,048 × 2,048 px | 1:1 | JPEG / WebP / PNG |
| Etsy (listing) | 2,700 × 2,025 px (min 2,000 px short side) | 4:3 | JPEG / PNG |
| eBay | 1,600 × 1,600 px (min 500 px) | 1:1 | JPEG |
| Meta feed ad (square) | 1,080 × 1,080 px | 1:1 | JPEG / PNG |
| Meta feed ad (portrait) | 1,080 × 1,350 px | 4:5 | JPEG / PNG |
| Stories / Reels | 1,080 × 1,920 px | 9:16 | JPEG / PNG |
| Google Shopping | 1,200 × 1,200 px (min 100 px, 250 px for apparel) | 1:1 | JPEG / PNG / WebP |
Why product image size matters
Image size affects three things at once: how sharp your product looks, whether platform features like pinch-to-zoom work, and how fast the page loads. Upload an image that is too small and Amazon disables zoom, which measurably reduces conversions. Upload one that is needlessly huge and unoptimised, and your store's load time suffers — which hurts both conversions and search ranking.
The goal is the sweet spot: large enough to look crisp and enable zoom, compressed enough to load fast. For most sellers that means a square image around 2,000 px, saved as an optimised JPEG or WebP under 1 MB.
Amazon product image size
Amazon's most important rule is the zoom threshold: images must be at least 1,000 px on the longest side for the zoom feature to activate. Amazon recommends 1,600 px or larger. The main image must have a pure white background (RGB 255, 255, 255), show only the product, and have the product fill at least 85% of the frame. JPEG is the preferred format.
Shopify product image size
Shopify supports images up to 4,472 × 4,472 px (20 megapixels) and up to 20 MB, but you should not upload files that large. A square 2,048 × 2,048 px image gives you sharp display and zoom on every theme without bloating page weight. Keep every product image the same dimensions and aspect ratio so your product grid stays visually consistent.
Etsy product image size
Etsy recommends at least 2,000 px on the shortest side, with 2,700 × 2,025 px (a 4:3 ratio) being the ideal. Because Etsy crops listing thumbnails to a landscape shape, keep your product centred with breathing room so nothing important gets cut off in the grid view.
Meta (Facebook & Instagram) ad image size
For paid ads, 1,080 × 1,080 px (1:1 square) is the safe default that works across feed placements. Portrait 1,080 × 1,350 px (4:5) takes up more screen space on mobile and often earns higher engagement. For Stories and Reels, use full-screen 1,080 × 1,920 px (9:16). Keep any text minimal — heavy text overlays can reduce delivery.
Rule of thumb: create your master product image as a 2,048 × 2,048 px square. It downsizes cleanly for every marketplace and ad placement. Then export platform-specific crops (4:5 and 9:16) from the same master so your product stays perfectly centred everywhere.
File format and compression
Use JPEG for photographic product images — it gives the best quality-to-size ratio and is accepted everywhere. Use PNG only when you need transparency (for example, a product cut-out on a transparent background). WebP is excellent for your own Shopify or website store because it is 25–35% smaller than JPEG at the same quality, but confirm the marketplace supports it before uploading. Aim to keep each file under 1 MB after compression.
Getting perfectly sized images without a shoot
The hardest part is producing sharp, correctly-sized, on-brand images for every placement in the first place. AI product photography tools solve this by generating high-resolution images you can export at any of the sizes above — a clean white-background version for Amazon, a lifestyle 4:5 crop for Meta, and a 9:16 version for Stories — all from a single uploaded product photo, without booking a studio.
