Facebook Character Limit: How Many Characters Per Post?
The Facebook character limit is 63,206 characters per post.
How Facebook's limit compares to other platforms
| Platform | Character limit | Native threading |
|---|---|---|
| 63,206 | No | |
| X | 280 | Yes |
| Bluesky | 300 | Yes |
| Threads | 500 | Yes |
| Mastodon | 500 | Yes |
| 3,000 | No |
Facebook has the most generous character limit of the major text-first platforms. Posts that would need to be split into threads on X, Bluesky, or Mastodon usually fit on Facebook as a single post.
What happens when you go over 63,206 characters
Facebook doesn't have native threading the way X or Bluesky do. Posts longer than 63,206 characters can't be split into a thread automatically — they need to fit in a single post. Fortunately, 63,206 is generous enough that most cross-posted content (even longer Threads or Mastodon posts) lands as a single post without truncation.
Other Facebook post limits
- Images per post: 30
- Alt text on images: Not supported
- Video: Supported, up to 600 seconds and 1024 MB
- Native threading: No — long content must fit in one post
Cross-posting and the Facebook character limit
When cross-posting from Facebook (63,206 chars) to platforms with tighter limits (X at 280, Bluesky at 300, Threads at 500, Mastodon at 500, LinkedIn at 3000), long posts need to be split into threads on the target platform. Ferryman handles all of this automatically: it watches your origin platform for new posts and replicates them to each target with the right behavior (native threading where supported, single-post fit where character limits allow).
