Threads limitations
Threads keeps posts short and applies firm media specs and daily quotas through its API. Replies are accessible to tools; DMs are not.
Publishing limits
The limits Threads applies to posts published through its official API. Posty checks every one of these while you compose.
| Limit | Value |
|---|---|
| Text length | 500 characters Emoji count as more than one character in Threads' counting. |
| Carousel size | 2–20 items (images and video can mix) |
| Images | JPEG or PNG, up to 8.0 MB |
| Video | MOV or MP4, up to 1.0 GB, max 5 minutes |
| Links | 5 unique links per post |
| Topic tag | 1 per post, up to 50 characters |
| API publishing volume | 250 posts per rolling 24 hours |
Rows marked Posty are current Posty product choices rather than hard platform rules.

Inbox & messaging
Public replies are supported; Threads has no DM API.

Good to know
- No native scheduling - Posty's scheduler publishes at the chosen time.
- Like counts on other people's replies aren't retrievable by any tool.
These limits apply to every tool
They come from Threads's official API, so no scheduler can exceed them. Posty validates against every limit on this page while you compose - if your post passes, Threads will accept it.
