Post an image at the wrong size and the platform crops it badly, blurs it, or pillarboxes it with ugly bars. Each social network expects specific dimensions. This guide gives you the right size for every major platform, then shows you how to resize your photo in seconds — for free, in your browser.
These are the recommended dimensions as of 2026. Platforms re-compress uploads, so starting at the correct size gives you the cleanest result.
| Platform | Post type | Dimensions (px) |
|---|---|---|
| Square post | 1080 × 1080 | |
| Portrait post | 1080 × 1350 | |
| Story / Reel | 1080 × 1920 | |
| Feed post | 1200 × 630 | |
| Twitter / X | In-stream image | 1600 × 900 |
| YouTube | Thumbnail | 1280 × 720 |
| Standard pin | 1000 × 1500 | |
| Feed post | 1200 × 627 |

Open Image Resizer →Tip: After resizing, compress the image to a smaller file. Smaller files upload faster and platforms compress them less aggressively, preserving quality.
Resizing scales the whole image up or down, keeping everything in frame. Cropping cuts away part of the image to change its shape or focus. For social media, you usually want to resize to the platform's dimensions while keeping the aspect ratio close to the target — then the platform won't crop it for you.
Making an image smaller (downscaling) keeps quality excellent — you're just discarding pixels you don't need. Making an image larger (upscaling) can't add detail that wasn't there, so a small image enlarged to a big size will look soft. Always start from the highest-resolution original you have.
