Why Instagram crops your photos
Instagram enforces strict dimension requirements for each content type. If your image doesn't match, it gets compressed, cropped, or upscaled — often with visible quality loss. The fix is simple: resize before uploading.

These are the exact pixel dimensions Instagram expects. Using them avoids any automatic cropping or quality degradation:

| Square Post | 1080×1080 | 1:1 |
| Story / Reel | 1080×1920 | 9:16 |
| Landscape | 1080×566 | 1.91:1 |
