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

“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
Facebook 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 20% — 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 .
