Using the correct dimensions for Instagram ensures your images display without cropping or quality loss. Here are the current recommended sizes:
| Image Type | Recommended Size | Aspect Ratio |
|---|---|---|
| Square Post | 1080 x 1080 px | 1:1 |
| Portrait Post | 1080 x 1350 px | 4:5 |
| Landscape Post | 1080 x 566 px | 1.91:1 |
| Story / Reel | 1080 x 1920 px | 9:16 |
| Profile Picture | 320 x 320 px | 1:1 |
For maximum feed presence, use 1080 x 1350 pixels (4:5 portrait). This format takes up the most vertical space in the feed. For square posts, use 1080 x 1080. Both display sharply on all devices.

Instagram supports aspect ratios from 1.91:1 (landscape) to 4:5 (portrait) for feed posts. Stories and Reels use 9:16 (full vertical). Square (1:1) remains supported but is no longer the default.
