Live counts for the post (500), text attachment (10,000), bio (150) and display name (30), measured the way Threads counts them. Everything runs in your browser; nothing you type is stored or sent anywhere.
How to use the Threads character counter
- Pick the field
Choose what you are writing: post, text attachment, bio, display name, username and topic tag. Each field has its own Threads limit. - Type or paste
The count updates on every keystroke, using Threads's own counting rules for emoji and links. - Watch the limit bars
Each bar turns amber past 90% of the limit and red when you are over, with the exact number of characters to trim. - Check the hook

Threads character limits in 2026
The Threads composer shows no counter while you write, surfaces one only near the limit and then stops accepting input; a draft pasted over 500 is cut mid-sentence with no error. Links are not shortened, so a 47-character link spends 47 of your 500.
| Field | Limit | Note |
|---|---|---|
| Post | 500 | replies get the same 500 |
| Text attachment | 10,000 | added in September 2025, rides on a normal post |
| Bio | 150 | - |
| Display name | 30 | - |
| Username | 30 | inherited from Instagram |
| Topic tag | 100 | one topic per post |
How Threads counts characters
Threads measures text in UTF-16 code units: most emoji cost 2, flags cost 4, and links count at their full written length because Threads does not shorten URLs.
Where the Threads feed cuts your post
Inside the 500-character limit the feed still does not show your whole post. Roughly the first 175 characters are visible before the "more" link, and the exact point varies by device, so a full-length post is judged on about a third of itself.
Put the hook, the claim or the question in the first sentence. If the counter shows you at 400+ characters, check that the part before ~175 can earn the tap on its own.
How to post more than 500 characters on Threads
There are two real options. Chain posts into a thread, where every reply gets its own 500 characters and each part can be liked and replied to on its own. Or add a text attachment, available since September 2025, which holds up to 10,000 characters on a normal post that still counts against 500.
Chains suit stories where each beat should be shareable; attachments suit essays and announcements. The Threads thread splitter cuts a long draft into parts under 500 at natural breaks.
The same text on other networks
One draft gets a different number on every network, because each one counts differently. Here is how the Threads limit compares.
| Network | Main limit | How it counts |
|---|---|---|
| X | 280 (post) | weighted: links 23, emoji 2, CJK 2 |
| Bluesky | 300 (post) | graphemes (emoji = 1) plus 3,000 bytes |
| 2,200 (caption) | every character, hashtags included; max 5 hashtags |
