Bio Counter — Free Character Counter
for Every Platform

Bio Counter is a free online bio character counter designed to help you craft the perfect social media bio for every platform. Whether you need an Instagram bio character counter tool, a TikTok bio character counter, or a Twitter bio counter, Bio Counter provides instant, accurate character counting with a beautiful live preview — all without requiring a sign-up.

Why Use a Bio Character Counter?

Every social media platform enforces strict character limits on profile bios. Instagram limits your bio to just 150 characters, TikTok allows only 80 characters, Twitter (X) gives you 160 characters, and LinkedIn's About section permits up to 2,600 characters. Exceeding these limits means your bio gets truncated, leaving your audience with an incomplete impression. Our bio length counter tracks every character, word, and emoji in real-time as you type, so you always know exactly how much space you have left.

Multi-Platform Bio Checker

Bio Counter is more than just a character counter — it's a comprehensive multi-platform bio checker that supports Instagram, YouTube, Twitter, TikTok, LinkedIn, Facebook, GitHub, and Twitch. Each platform has different character limits for your bio, display name, and username. Our social media bio tool automatically adjusts to show the correct limits for whichever platform you select, making it the only bio length checker for social media you'll ever need.

Live Bio Preview with Phone Mockup

One of the most powerful features of Bio Counter is the Instagram bio preview and TikTok bio preview mockup. See exactly how your bio will appear on a real phone screen before you copy and paste it into your social media profile. The live preview updates in real-time as you type, showing your bio with the display name, username, and any emojis or special fonts you've added. This bio character counter with live preview eliminates the guesswork from writing your perfect bio.
