Threads is Meta’s text-first network, connected to your Instagram account. It rewards conversation: replies, quotes and back-and-forth discussions spread posts further than likes.
Limits
| Field | Limit |
|---|---|
| Post | 500 characters |
| Topic tag | 1 per post |
| Images / video | Up to 20 per post; video up to 5 minutes |
| Bio | 150 characters (shared with Instagram) |
What to post
- Opinions with a reason. Short, clear takes invite replies.
- Questions your audience can answer in one line.
- Mini-threads: split longer ideas into connected posts. The Thread Maker has a 500-character Threads mode.
- Behind the scenes of your work, written casually.
Reply your way to followers
On Threads, thoughtful replies to bigger accounts in your niche are one of the fastest ways to grow. Spend 15 minutes a day replying with something useful, not “great post”.
One topic tag
Threads uses a single topic tag instead of hashtags. Choose the tag that matches your niche so the post appears in that topic feed.
Repurpose without copying
Your X posts and Instagram captions are good raw material. The Caption Repurposer cuts any caption to Threads’ 500-character limit with one tag. Great Threads posts can become Instagram images with the Post to Image tool.
