Facebook Character Limit: 63,206 Characters
Last updated July 2026
The Facebook character limit is 63,206 characters per post. That's the most generous cap of the major networks — far beyond LinkedIn's 3,000.
Note: The limit is huge, but 40–80 characters wins engagement.

What happens when you exceed the limit
Facebook has no native threading, so anything past 63,206 characters is simply cut off — the post is truncated rather than continued. To publish longer content you either trim it to fit or move the overflow into a comment or a linked article.
Ideal Facebook post length
While you can use all 63,206 characters, the engagement sweet spot on Facebook is around 40–80 characters. Leading with a tight, front-loaded hook tends to outperform maxing out the limit.
Cross-posting to Facebook with Postwake
Postwake watches the platform you actually write on and replicates each post to Facebook within seconds. Because Facebook can't thread, Postwake adapts longer content to fit its 63,206-character cap. It's deterministic by design: no double-posts, no black-box AI, and if a platform rejects a post you get the exact error and a retryable action.
