X Character Limit: How Many Characters Per Post?
The X character limit is 280 characters per post (Twitter kept the same limit at launch). X Premium subscribers can post up to 4,000 characters; verified organizations get 25,000.
How X's limit compares to other platforms
| Platform | Character limit | Native threading |
|---|---|---|
| X | 280 | Yes |
| Bluesky | 300 | Yes |
| Threads | 500 | Yes |
| Mastodon | 500 | Yes |
| 3,000 | No |
X has the tightest character limit of the major text-first platforms. Most long posts written for Threads, Mastodon, or LinkedIn will need to be split into a thread to fit on X.
What happens when you go over 280 characters
X supports native threading. If your post exceeds 280 characters, you can split it across multiple posts in a thread — and tools like Ferryman do this automatically when cross-posting from a platform with a more generous limit (like LinkedIn's 3,000 characters). The reading experience stays clean: each post is a separate item in the feed, but they're chained together as a single thread.
Other X post limits
- Images per post: 4 (up to 5 MB each)
- Alt text on images: Supported
- Video: Supported, up to 140 seconds and 512 MB
- Native threading: Yes — posts can be chained into a native thread
Cross-posting and the X character limit
Cross-posting from X to platforms with more generous limits (Bluesky at 300, Threads at 500, Mastodon at 500, LinkedIn at 3,000) is straightforward — your posts always fit. 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).
