Bio character counter
Paste your bio to see how many characters you have left on Instagram, X, GitHub, Pinterest, Twitch, and SayHi. It counts in your browser, so nothing is uploaded.
How to use the counter
- Paste the bio you want to use, or start typing.
- Watch the Left column. A negative number means you are over the limit for that field.
- Trim words until every platform you care about shows zero or more.
- Paste the final version into your profile.
Tips for a short bio
- Lead with what you do, then who it is for. “Wedding photographer in Lisbon” says more than a list of hobbies.
- Cut filler like “passionate about” and “lover of all things”.
- Some platforms drop or change symbols and line breaks, so check your profile once you’ve saved it.
- Short on space? Put the longer version on a page and link to it. The X, YouTube, Pinterest, and Twitch guides show where that link goes.
Where the limits come from
Each limit comes from the platform’s own help page, last checked 2026-10-22.
- Instagram bio: 150 (Instagram Help, “Add a bio to your Instagram profile”)
- X bio: 160 (X Help, “How to customize your profile”)
- X display name: 50 (X Help, “How to change your X username”)
- GitHub bio: 160 (GitHub Docs, “Personalize your profile”)
- Pinterest about: 500 (Pinterest Help, “Edit your profile”)
- Twitch channel bio: 300 (Twitch Help, “Channel Page Setup”)
Questions
Why does my count differ from the app’s?
Platforms do not all count characters the same way. This counter counts Unicode code points, so most emoji count as one. Some apps count certain emoji or accented letters as two. If you are within a few characters of the limit, paste it into the app to be sure.
Why aren’t TikTok, YouTube, LinkedIn, Facebook, or Snapchat listed?
Their help pages did not state a bio character limit when we last checked, and we only list limits we can link to an official source.
What are the SayHi limits?
A SayHi page allows 80 characters for your display name, 140 for the headline, and 600 for the bio, so you have room to say more than a social profile allows.
Need more than 150 characters?
A free SayHi page gives you room for a longer bio, your links, and your work.
