About Bio Character Counter

The Bio Character Counter helps you write social media bios that fit. Pick a platform and it sets the right limit, then counts your characters live as you type, showing how many you have used, your limit, and how many remain. Go over and the numbers turn red so you can trim before you post.

It handles Instagram, X / Twitter, TikTok, YouTube, and LinkedIn, and counts emoji correctly so each one counts as a single character. The tool is completely free and runs entirely in your browser, with nothing to install and no sign-up.

Frequently asked questions

Is the Bio Character Counter free?
Yes, it is completely free with no sign-up, no account, and no limits on how many times you use it. Just pick a platform, type or paste your bio, and see the counts instantly.
Is my data uploaded or stored anywhere?
No. Everything is counted live in your browser on your own device. Your bio text is never sent to a server, uploaded, or stored, so it stays completely private.
What are the character limits for each platform?
The tool uses the standard public limits: Instagram bio 150 characters, X / Twitter bio 160, TikTok bio 80, YouTube description 1,000, and LinkedIn headline 220 characters. Select a platform to apply its limit automatically.
How are emojis counted?
Emojis are counted using Array.from, so each emoji counts as a single character even when it is made of multiple underlying code units. This matches how the platforms themselves measure bio length.
What happens if my bio is over the limit?
The remaining count goes negative and turns red, and a message tells you exactly how many characters you need to remove. This makes it easy to trim your bio down until it fits.
Which platforms does the Bio Character Counter support?
It supports Instagram bios, X / Twitter bios, TikTok bios, YouTube descriptions, and LinkedIn headlines. You can switch between them at any time and your text stays in place while the limit updates.
