Image sizes for every social platform
Every platform resizes whatever you give it. Uploading at the right dimensions means that resize does nothing, which is the only way to keep the image sharp.
Why uploading the wrong size hurts
When you upload an image larger than a platform's display size, it scales it down and re-compresses it, usually aggressively and usually with worse resampling than you would get doing it yourself. Upload something smaller and it scales up, which is worse again — there is no detail to invent.
Matching the target dimensions exactly means the platform has nothing to do, and what you uploaded is what people see.
The sizes
- Feed post (square) 1080×1080 — resize · crop
- Feed post (portrait) 1080×1350, the tallest shape the feed shows uncropped — fit a whole photo
- Story / Reel 1080×1920 — resize
- Profile picture 320×320 — make one
Feed posts must be between 1.91:1 landscape and 4:5 portrait, so a normal 3:4 phone photo loses its top and bottom. To keep all of it, see how to post a full picture on Instagram without cropping.
Instagram's grid is worth a note: the newest post takes the top-left spot, so a nine-tile mosaic has to be uploaded backwards, from tile 9 to tile 1. Our image splitter numbers the tiles and says so on the page, and our guide to splitting an image covers the tile sizes.
YouTube
- Thumbnail 1280×720, under 2 MB — resize
- Channel banner 2560×1440, with the safe area in the middle 1546×423 — resize
- Channel icon 800×800 — make one
The banner is the one people get wrong. It is displayed at wildly different crops on a phone, a laptop and a television, so anything important has to sit inside that central safe area or it will be cut off for most viewers.

TikTok and Pinterest
Marketplaces
- Amazon 2000×2000, pure white background required for the main image — resize
- Etsy 2000×2000, and note the 1 MB limit, which is tight — resize
- eBay 1600×1600 — resize
- Shopify 2048×2048 — resize
Marketplace photos usually need a clean white background. A studio shot can be keyed out with the chroma key tool if the background is a consistent colour; a messy background needs an AI background remover, which is on the way.
Chat and gaming profiles
- Discord 512×512 — make one
- WhatsApp 640×640 — make one
- Twitch 256×256 — make one
- Slack 512×512 — make one
- GitHub 500×500 — make one
Two things that apply everywhere
Profile pictures are displayed as circles on essentially every platform, even though you upload a square. Anything in the corners will be cut. Our avatar maker shows the circle while you position the crop.
Every platform strips or ignores your metadata — but not all of them, not on every upload path, and not on the original file if someone downloads it from a direct link. If the photo has GPS coordinates in it, remove them before uploading rather than trusting the platform to.
These specs change. Each is dated on its own tool page, and we re-check them quarterly.
