Social media platforms silently compress and crop images that don't match their preferred dimensions. Using the right size from the start keeps your visuals sharp and avoids unexpected cropping. Here's the complete 2026 reference.
Instagram image sizes 2026
| Post type | Dimensions | Aspect ratio |
|---|
| Square post | 1080 × 1080 px | 1:1 |
| Portrait post | 1080 × 1350 px | 4:5 |
| Landscape post | 1080 × 566 px | 1.91:1 |
| Story / Reel | 1080 × 1920 px | 9:16 |
| Profile picture | 320 × 320 px | 1:1 |
Instagram recompresses all uploads. Using exact pixel dimensions prevents a second lossy compression pass, which would degrade quality noticeably.
