Frequently Asked Questions

Common questions about character limits and how the tool works.

Facebook posts can be up to 63,206 characters long. In practice, the feed truncates posts after approximately 477 characters on desktop and around 125 characters on mobile, showing a \"See more\" link. Posts under 80 characters tend to see the highest engagement.
Facebook ad headlines are limited to 40 characters — one of the tightest limits in digital advertising. Lead with a clear benefit and use active language.
Facebook ad primary text is technically longer, but only the first 125 characters display reliably across all placements including mobile. Write your key message and CTA within that window.
The Facebook profile About section (bio) is limited to 101 characters for personal profiles. Facebook Pages get a longer 255-character short description field instead.
