Instagram character limits and image sizes
This page lists every Instagram text limit and upload size tracked by the tool, including the point where Instagram truncates a post in the feed. Counts follow how Instagram itself measures text, not raw string length.
Instagram character limits
| Field | Limit | Visible in feed |
|---|---|---|
| Caption | 2,200 | ~125 |
| Bio | 150 | — |
| Comment | 2,200 | — |
| Reels caption | 2,200 | ~90 |
“Visible in feed” is roughly where the platform collapses the rest behind a “more” link. It is the practical limit for anything you need read.

Safe zones
Instagram lays its own interface over vertical video — profile details at the top, captions and buttons at the bottom. Keep text and logos inside the safe area shown in the tool.
- Story (1080 × 1920) Platform UI covers roughly the top 14% and bottom 14% — keep captions and logos inside the dashed box.
- Reel (1080 × 1920) Platform UI covers roughly the top 14% and bottom 35% — keep captions and logos inside the dashed box.
