Character counter for social media: check your text against every limit
Type or paste your post, bio, name or username and see at once whether it fits each app’s limit, how many characters you have left, and, where the app publishes its rules, whether a username uses allowed characters. It covers 30 limits across 10 apps, each from the app’s own help pages.

Questions about character limits
Is what I type sent anywhere?
No. The counting happens in your browser. Your text isn’t sent, saved or put in the page address.
Why does an app count my text differently?
We count characters the way you see them, so an emoji or an accented letter counts as one. An app’s own counter may not match ours exactly, so treat a result close to the limit as approximate and check the app’s counter.
Where do the limits come from?
Every limit comes from the app’s own help pages, linked in the table below, and is explained in one of our guides. Where an app gives two different figures, we show both.
What about photo and video sizes?
Use our Upload Checker: pick a photo or video and it checks the size, length and format against each app’s published limits.
Why isn’t my app or field listed?
We only list limits we’ve read on an official help page. We add more as we verify them.
