Social Media Character Limits
Every platform caps the length of a single post differently. Here's the quick reference, with detailed pages on what happens when you go over, how each platform handles threading, and how to cross-post between platforms with different limits.
| Platform | Character limit | Native threading |
|---|---|---|
| X | 280 | Yes |
| Bluesky | 300 | Yes |
| Threads | 500 | Yes |
| Mastodon | 500 | Yes |
| 3,000 | No |
