Social media image sizes: 2026 cheat sheet
Updated 2026 · ~7 min read
Every platform crops and compresses images differently. Uploading the right dimensions keeps your photos sharp and stops awkward cropping. Here are the sizes that work well in 2026, plus the fastest way to hit them.
Why exact sizes matter
If you upload an image with the wrong aspect ratio, the platform crops it — often cutting off heads or text. Too few pixels and the platform's compression makes it blurry. Matching the recommended size means your image displays exactly as you intended.
| Placement | Size (px) | Ratio |
|---|---|---|
| Square post | 1080 × 1080 | 1:1 |
| Portrait post | 1080 × 1350 | 4:5 |
| Story / Reel | 1080 × 1920 | 9:16 |
| Profile photo | 320 × 320 | 1:1 |
YouTube
| Placement | Size (px) | Ratio |
|---|---|---|
| Thumbnail | 1280 × 720 | 16:9 |
| Channel banner | 2560 × 1440 | 16:9 |
| Video (1080p) | 1920 × 1080 | 16:9 |
Facebook · X · LinkedIn · TikTok
| Placement | Size (px) |
|---|---|
| Facebook shared post | 1200 × 630 |
| X (Twitter) post | 1600 × 900 |
| LinkedIn shared image | 1200 × 627 |
| TikTok video | 1080 × 1920 |
| Open Graph / link preview | 1200 × 630 |
Platforms tweak these over time, but staying within these dimensions is safe and looks clean everywhere.
How to resize quickly
Our resize & crop tool has one-tap presets for the most common sizes (square, story, YouTube, Open Graph), or you can type exact pixels. If your source image is too small to fill a large format cleanly, upscale it first, then resize. Everything runs in your browser — no upload.
