The character limit for a Threads post is 500 characters.
Threads, Meta’s text-based platform that launched in July 2023, positions itself between Twitter’s 280 characters and longer-form platforms. The 500-character limit encourages concise but complete thoughts.

How Threads compares to other text platforms
| Platform | Character limit |
|---|---|
| Threads | 500 |
| X (Twitter) | 280 |
| Bluesky | 300 |
Threads gives you nearly double the space of X and Bluesky. This extra room is enough to make a complete point without needing a thread.
Tips for Threads posts
- One idea per post — 500 characters is enough for a single clear thought
- Conversational tone — Threads culture is casual and personal
- Use carousels — multi-image posts perform well for visual storytelling
- Cross-post from Instagram — Threads is linked to your Instagram account and audiences overlap
- Engage in replies — the algorithm rewards conversation
