What happens when you go over
Input stops at 500. Since September 2025 you can attach further text to the post rather than splitting it into a chain.
The attached long text is read inside Threads instead of as a screenshot, which is the difference between it being indexable text and being an image.

Does Threads count emoji differently?
Threads publishes its limit in plain characters, so an emoji costs the same as a letter in the field itself. How the emoji is stored underneath can still differ: see the methodology page for the four ways WordBench measures the same text.
Where does this number come from?
From Introducing Threads, Meta newsroom, linked in the sources section on this page. Nothing here is estimated or copied from another character counter, and every figure carries the date it was last checked.
How many characters can a Threads post have?
500 characters, according to Introducing Threads, Meta newsroom, checked on 23 July 2026. Input stops at the limit rather than cutting the post.
Can a Threads post be longer than 500 characters?
Not the post itself, which stops at 500 characters. Since September 2025 you can also attach up to 10,000 further characters of text to a post, which is read inside Threads rather than as a screenshot.
How does the Threads limit compare to X and Bluesky?
A Threads post allows 500 characters, a Bluesky post 300 graphemes and a post on X from a free account 280 weighted units. The units differ, which matters as soon as emoji appear: X counts every emoji twice, Bluesky counts it as one grapheme.
