Threads limits cheat sheet

The limits Threads enforces on a post, from Meta's own documentation. Each row links to its source. Limits change, so check the date at the bottom of this page.

Text

What	Limit	Source
Post text	500 characters	Threads API: Posts
Emoji	Count as their UTF-8 bytes: 🚀 = 4, 👍🏽 = 8, a flag = 8	Threads API: Posts
Links	At most 5 per post	Threads API: Posts
Link preview card	Text-only posts	Threads API: Posts
Text attachment	Up to 10,000 characters, on text posts and replies; not with images, a poll, a link card or a GIF	Threads API: Text attachments, Meta newsroom, Sept 2025
Quote posts	Any post type; the quoting post needs its own text	Threads API: Quote posts
Replies	Same 500-character limit as posts	Threads API: Posts

Check a post against these with the character counter, or split a long text with the thread splitter.

Questions

Is the bio limit listed? No. Meta doesn't publish it in its documentation, and we only list limits we can source.

Do these limits differ for verified accounts? Meta's documentation doesn't list any differences.

Something changed? Tell us at support@govir.app and we'll check and update this page.
