Image Size Cheat Sheet: Marketplaces & Social 2026
Exact image sizes and aspect ratios for Amazon, eBay, Etsy, Shopify, Instagram, TikTok, YouTube, LinkedIn and more, plus how to hit them from one photo.
Most teams keep re-shooting or re-cropping because they cannot find one place that lists the image size for every channel they publish to. This is that place. Below is the current required or recommended image size and aspect ratio for the major marketplaces and social platforms, in one table per group, kept practical rather than exhaustive.
The short version: you do not need a different shoot for each channel. Most of these surfaces map to a handful of aspect ratios — 1:1, 4:5, 9:16, 16:9, 2:3, and 1.91:1 — and you can produce every one of them from a single high-resolution source photo by extending the canvas instead of cropping the subject.
Marketplace image sizes
| Platform | Main image | Aspect ratio | Notes |
|---|---|---|---|
| Amazon | 2000 x 2000 px | 1:1 | Pure white background, product fills ≥85% of frame |
| eBay | 1600 x 1600 px | 1:1 | 1600 px on the longest side recommended for zoom |
| Etsy | 2000 x 2000 px | 1:1 (listing) | First image also shows as 4:3 in some views |
| Shopify | 2048 x 2048 px | 1:1 product | Hero banners render best at 1.91:1 |
| Walmart Marketplace | 2000 x 2000 px | 1:1 | White background, ≥1000 px minimum |
| Google Shopping | 1000 x 1000 px+ | 1:1 | No promotional text or watermarks allowed |
The recurring trap here is the 1:1 requirement. A camera shoots 4:3 or 3:2, so forcing it to a square either crops the product or leaves it floating. Extending the background to a clean square keeps the product untouched, which is exactly what Amazon and Walmart fill-ratio rules reward.
Social media image sizes
| Platform / placement | Size | Aspect ratio |
|---|---|---|
| Instagram feed (portrait) | 1080 x 1350 px | 4:5 |
| Instagram square | 1080 x 1080 px | 1:1 |
| Instagram / Facebook Stories & Reels | 1080 x 1920 px | 9:16 |
| TikTok | 1080 x 1920 px | 9:16 |
| Pinterest pin | 1000 x 1500 px | 2:3 |
| YouTube thumbnail | 1280 x 720 px | 16:9 |
| Facebook / LinkedIn link preview | 1200 x 627 px | 1.91:1 |
| X (Twitter) in-stream | 1600 x 900 px | 16:9 |
| LinkedIn feed image | 1200 x 1200 px | 1:1 |
Ad placement sizes
| Placement | Size | Aspect ratio |
|---|---|---|
| Meta feed ad | 1080 x 1080 px | 1:1 |
| Meta Stories/Reels ad | 1080 x 1920 px | 9:16 |
| Google Display (square) | 1200 x 1200 px | 1:1 |
| Google Display (landscape) | 1200 x 628 px | 1.91:1 |
| YouTube in-feed | 1280 x 720 px | 16:9 |
The six ratios that cover everything
Strip the table down and almost every surface above is one of six ratios:
- 1:1 — marketplaces, feed squares, display ads
- 4:5 — Instagram and Facebook feed portrait
- 9:16 — Stories, Reels, TikTok
- 16:9 — YouTube, X, video thumbnails
- 2:3 — Pinterest
- 1.91:1 — link previews and landscape display ads
That is why one good photo is enough. Convert it once per ratio you actually publish to, and keep the originals named by ratio so you are not regenerating later. The per-ratio presets live on the aspect ratio hub, and the 1:1 square, 4:5 portrait, 9:16 vertical, and 16:9 widescreen pages each have their own outpaint tips.
Crop vs extend: why this matters for quality
Cropping to a new ratio throws away pixels and frequently clips the subject. Extending the canvas with outpainting adds new pixels around the original, continuing the background, lighting, and perspective so the subject stays whole. For a clean, white-background marketplace shot this is the difference between a compliant listing image and a rejected one. For the operation-by-operation breakdown, see outpaint vs upscale vs content-aware fill, and for the cases where extension still needs a human eye, see when AI outpaint fails.
How to produce every size from one photo
- Start from the highest-resolution original you have, ideally the full uncropped camera file.
- List the channels you actually publish to and map each to one of the six ratios above.
- Extend, do not crop. For each target ratio, grow the canvas around the subject so nothing is clipped.
- Add a one-line prompt hint for cluttered scenes, such as continue the wooden floor, so the model extends the right surface.
- Export at the platform’s pixel size from the table, not a resized copy.
- Audit the marketplace shots against the fill-ratio and white-background rules before publishing.
You can run the full workflow on the image extender tool, or jump straight to a use-case bundle for e-commerce, real estate, or social media.
Frequently asked questions
What is the most common image size for online marketplaces? A 1:1 square at 2000 x 2000 pixels covers Amazon, eBay, Etsy, Walmart, and Shopify product images. It is the single most useful size to have ready.
What aspect ratio should I use for Instagram? 4:5 portrait (1080 x 1350 px) for the feed because it uses the most vertical space, 1:1 for a square post, and 9:16 (1080 x 1920 px) for Stories and Reels.
Can I resize one photo for every platform without re-shooting? Yes, if you extend the canvas instead of cropping. Cropping clips the subject for tall or wide ratios; outpainting grows the background around the subject so a single source photo can hit all six common ratios.
What size should a YouTube thumbnail be? 1280 x 720 pixels at 16:9. Keep important elements away from the bottom-right corner where the duration stamp appears.
Do marketplace images really need a white background? Amazon, Walmart, and Google Shopping require or strongly prefer a plain white background for the main image. Extending a product shot to a clean white square is the safest way to meet this without re-shooting.
One source photo, six ratios, every channel. Keep this table bookmarked and extend rather than crop, and you stop paying for a new shoot every time a platform changes its layout.
