How to use it
- Type or paste your bio; line breaks count too.
- Check the bars: each platform shows how many characters you have left or how far over you are.
- Copy the finished bio with the button. Your draft is saved in this browser.
Why visible characters and UTF-16 differ
What looks like one character can be several units to a computer. A plain emoji (😀) is two UTF-16 units, a thumbs-up with a skin tone (👍🏽) is four, a flag (🇺🇸) is four and a family emoji can be eleven. Fancy letters such as 𝓐 count as two as well. Instagram, TikTok and YouTube use the browser's standard length limit, which counts UTF-16 units – that's why a bio with only 140 visible characters can still be too long for Instagram's 150. X and Discord count code points. This counter measures each platform its own way and labels what it counts.
Bio limits by platform
Instagram bio: 150. TikTok bio: 80. X (Twitter) bio: 160. Discord About me: 190. Twitch bio: 300. YouTube channel description: 1,000. LinkedIn headline: 220. Threads bio: 150. These are the limits as of November 2026; platforms change them now and then, so if one won't save your text, trim a few characters. Usernames (@handles) follow different rules: they don't accept emoji or fancy letters at all.
