Getting your product photo dimensions right is one of those things that sounds trivial but directly impacts your sales. Wrong sizes mean broken zoom, blurry thumbnails, stretched images, or — worst case — your listing gets flagged or rejected.
This guide covers the exact image specifications for every major e-commerce marketplace in 2025. Bookmark it.
Etsy
| Spec | Requirement |
|---|
| Recommended size | 2000 x 2000 px |
| Minimum size | 2000 x 2000 px (for zoom) |
| Aspect ratio | 1:1 (square, displayed as 4:3 in some views) |
| Max file size | 1 MB |
| Formats | JPG, PNG, GIF |
| Max images per listing | 10 |
Etsy strongly recommends square images at 2000x2000px minimum for the zoom feature to work properly. Images below this size will have broken or blurry zoom, which hurts conversions. The first image is your thumbnail in search — make it count.
Amazon
| Spec | Requirement |
|---|
| Recommended size | 2000 x 2000 px |
| Minimum size | 1000 x 1000 px (for zoom) |
| Aspect ratio | 1:1 (square) |
| Max file size | 10 MB |
| Formats | JPEG, TIFF, PNG, GIF |
| Max images per listing | 9 (1 main + 8 additional) |
Amazon's main image
must have a pure white background (RGB 255, 255, 255). The product must fill at least 85% of the image frame. No text, logos, watermarks, or borders on the main image. Additional images have more flexibility — you can show lifestyle shots, infographics, or size comparisons.
Shopify
| Spec | Requirement |
|---|
| Recommended size | 2048 x 2048 px |
| Maximum size | 4472 x 4472 px (20 megapixels) |
| Aspect ratio | Varies by theme (1:1 most common) |
| Max file size | 20 MB |
| Formats | JPEG, PNG, GIF, HEIC, WebP |
| Max images per product | 250 |
Shopify is the most flexible platform. Image requirements depend on your theme, but 2048x2048 square images work with virtually every theme. Shopify automatically generates multiple sizes for responsive display, so upload the highest quality you have (up to their limits). WebP is supported for better compression.
eBay
| Spec | Requirement |
|---|
| Recommended size | 1600 x 1600 px |
| Minimum size | 500 x 500 px |
| Aspect ratio | 1:1 (square recommended) |
| Max file size | 12 MB |
| Formats | JPEG, PNG, GIF, TIFF, BMP |
| Max images per listing | 24 |
eBay is relatively lenient on image specs, but 1600x1600 is the sweet spot for their zoom functionality. White or light gray backgrounds perform best in search results. eBay allows up to 24 free images per listing — use them. More photos correlate with higher conversion rates.
Walmart Marketplace
| Spec | Requirement |
|---|
| Recommended size | 2000 x 2000 px |
| Minimum size | 1000 x 1000 px |
| Aspect ratio | 1:1 (square) |
| Max file size | 5 MB |
| Formats | JPEG, PNG |
| Max images per listing | 10 |
Walmart requires a
pure white background for the main product image, similar to Amazon. Product must occupy at least 85% of the frame. No props, accessories, or lifestyle elements in the main image. Additional images can include lifestyle shots and infographics.
Poshmark
| Spec | Requirement |
|---|
| Recommended size | 1200 x 1200 px |
| Minimum size | 640 x 640 px |
| Aspect ratio | 1:1 (square, enforced) |
| Max file size | 15 MB |
| Formats | JPEG, PNG |
| Max images per listing | 16 |
Poshmark strictly enforces square images. When you upload, the app crops to square automatically, which can cut off parts of your image. Better to pre-crop to square yourself so you control the composition. Flat lay photography works exceptionally well on Poshmark — their user base expects it.
Depop
| Spec | Requirement |
|---|
| Recommended size | 1280 x 1280 px |
| Minimum size | 640 x 640 px |
| Aspect ratio | 1:1 (square) or 4:5 |
| Max file size | 15 MB |
| Formats | JPEG, PNG |
| Max images per listing | 4 |
Depop has a visual, Instagram-like feed, so image quality heavily impacts engagement. The platform supports both square (1:1) and portrait (4:5) aspect ratios. Lifestyle and modeled shots significantly outperform flat lays on Depop. Only 4 images per listing, so each one needs to be strong.
Mercari
| Spec | Requirement |
|---|
| Recommended size | 1080 x 1080 px |
| Minimum size | 640 x 640 px |
| Aspect ratio | 1:1 (square) |
| Max file size | 10 MB |
| Formats | JPEG, PNG |
| Max images per listing | 12 |
Mercari is mobile-first, so most buyers view listings on phones. Ensure your photos look good at mobile resolution — clear, well-lit, with the product centered. The app compresses images during upload, so start with high quality to compensate.

Universal Tips for All Marketplaces
Start with the Largest Size
Shoot and save your originals at the highest resolution possible. You can always resize down without losing quality, but you can never add pixels back. If you're selling on Amazon (2000px) and Poshmark (1200px), capture at 2500px+ and resize down for each.
Use Consistent Lighting
Natural, diffused light produces the most accurate color representation. This matters because marketplace customers can't touch your product — they rely entirely on photos for color and texture accuracy. Inconsistent lighting across your listing photos looks unprofessional.
Leave Padding Around Your Product
Don't fill the entire frame edge-to-edge. Leave 10-15% padding around the product. This gives resizing tools room to adjust without cropping into the product, and it gives marketplaces room for their UI overlays.
Test on Mobile
Over 60% of e-commerce traffic is mobile. Check your resized images on a phone before publishing. What looks fine on a 27" monitor might be unreadable on a 6" screen.
Batch Resize for Each Platform
Instead of manually resizing for each marketplace one at a time, use a tool with marketplace presets. PhotoSizer lets you select your target marketplace and batch resize all your product photos at once — for free, right in your browser.
Keep This Guide Handy
Marketplace image requirements change occasionally. We'll update this guide as platforms update their specs. In the meantime, try PhotoSizer to automate the resizing — select your marketplace, upload your photos, and download perfectly sized images in seconds.
