**Instagram Feed photo 2026: aspect ratio 1.91:1, 1:1, 4:5, 3:4, recommended 1080x1440, files up to 8 MB, caption up to 2,200 characters, up to 5 hashtags.**

## All specs

| Aspect ratio | 1.91:1, 1:1, 4:5, 3:4 |
|---|---|
| Recommended resolution | 1080x1440 |
| Minimum resolution | 320 px width |
| Maximum file size | 8 MB |
| File types | JPEG |
| Caption limit | 2,200 characters |
| Visible before «more» | 125 characters |
| Hashtag limit | 5 |

Notes (from the sources, in English): Help Centre: photos are shared at up to 1,080 px wide; aspect ratios between 1.91:1 and 3:4 (1080 wide, 566 to 1440 tall) keep original resolution, others are cropped; below 320 px width is upscaled. Graph API still lists 4:5 to 1.91:1, JPEG only, 8 MB max and 320 to 1440 px width (API values used for file type and size). Visible caption length is an industry figure.

Work out bitrate and file size with the [file size calculator](https://shortformkit.com/video-file-size-calculator/). Check caption length with the [character counter](https://shortformkit.com/character-counter/).
