TikTok character limits and image sizes
This page lists every TikTok text limit and upload size tracked by the tool, including the point where TikTok truncates a post in the feed. Counts follow how TikTok itself measures text, not raw string length.
TikTok character limits
| Field | Limit | Visible in feed |
|---|---|---|
| Caption | 2,200 | ~100 |
| Bio | 80 | — |
| Username | 24 | — |
“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.
TikTok image and video sizes
| Placement | Dimensions | Ratio | Type |

| Video cover | 1,080 × 1,920 | 9:16 | Image |

Safe zones
TikTok 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.
- Video (1080 × 1920) Platform UI covers roughly the top 10% and bottom 25% — keep captions and logos inside the dashed box.
Limits for other networks
