Threads Character Limit: How Many Characters Per Post?

How Threads's limit compares to other platforms

Threads's 500-character limit sits in the middle of the major text platforms — more generous than X's standard limit, tighter than LinkedIn's. Most Threads posts cross-post cleanly to platforms with similar limits, and require thread splitting on platforms with shorter ones.

What happens when you go over 500 characters

Threads supports native threading. If your post exceeds 500 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 Threads post limits

• Images per post: 10
• Alt text on images: Supported
• Video: Supported, up to 300 seconds
• Native threading: Yes — posts can be chained into a native thread

Cross-posting and the Threads character limit

When cross-posting from Threads (500 chars) to platforms with tighter limits (X at 280, Bluesky at 300), long posts need to be split into threads on the target platform. Cross-posting from Threads to platforms with more generous limits (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).
