How it works
Type or paste your profile bio and this counter checks it against the character limit of every major social network at once — Instagram, Threads, X, TikTok, LinkedIn, Facebook, YouTube, Pinterest, Bluesky, GitHub, Discord and Twitch. Each row shows how many characters you have used, a bar that turns amber near the limit and red once you go over, and exactly how many characters are left.
Characters are counted as graphemes using the browser's Intl.Segmenter, so a
family emoji or a flag counts as one character just like it does in the app — a plain
string.length would count it as two to eleven. Line breaks count as
characters too, which matters on Instagram where a multi-line bio is common. Everything
runs in your browser with JavaScript; your bio is never uploaded, stored or logged.
Frequently asked questions
How many characters can an Instagram bio be?
An Instagram bio is limited to 150 characters, and line breaks count towards that total — so a four-line bio spends three characters on the breaks alone. Threads uses the same 150-character limit, X allows 160, TikTok only 80 and a Facebook Page bio 101. Paste your text above and every one of those limits is checked at the same time, with the number of characters you have left shown next to each network.
Why does my emoji count as more than one character in other counters?
Most counters use JavaScript's string length, which counts UTF-16 code units rather than characters. A single family emoji is built from four emoji joined by three zero-width joiners, so it measures as 11 there but as one character in the Instagram or X app. This tool segments your text into grapheme clusters with the browser's Intl.Segmenter, so an emoji, a flag or an accented letter counts as exactly one — the same way the platform counts it. The UTF-16 figure is still shown separately if you need it.
What is the character limit for a LinkedIn headline?
A LinkedIn headline allows 220 characters and the About section allows 2,600, which is why a headline that reads well on its own often gets cut off when reused as an Instagram or TikTok bio. The list on this page shows both LinkedIn fields alongside every other network, so you can write one bio and immediately see which platforms need a shorter variant. Tick "Show only platforms you are over" to see just the ones that need trimming.
