YouTube character limits and image sizes
This page lists every YouTube text limit and upload size tracked by the tool, including the point where YouTube truncates a post in the feed. Counts follow how YouTube itself measures text, not raw string length.
YouTube character limits

| Description | 5,000 | ~157 |
| Tags (total) | 500 | — |
| Community post | 1,500 | — |
| Channel description | 1,000 | — |
“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
YouTube 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.
- Shorts (1080 × 1920) Platform UI covers roughly the top 10% and bottom 20% — keep captions and logos inside the dashed box.
- Channel banner (2560 × 1440) Platform UI covers roughly the top 35% and bottom 35% — keep captions and logos inside the dashed box.
Limits for other networks
Limits are checked against public platform documentation and change occasionally — verify anything business-critical. Limits last reviewed .
