Handles and brand names run into hard length limits. Type a name to see its character, word and syllable counts, and whether it fits the usual limits for X, Instagram, TikTok, Twitch, YouTube, Discord, Reddit, GitHub, Minecraft and domain names. Spaces are ignored because handles can't contain them.
Do
- Aim a little under the shortest limit you care about so you have room for a number or underscore
- Confirm on the platform's sign-up page, since limits and allowed characters change
Don't
- Assume a name that fits is available — use the Domain Availability Checker for domains
- Forget that some platforms restrict characters (such as dots or underscores) beyond length
Common Questions
Why does the counter ignore spaces?
Usernames, handles and domain names don't allow spaces, so the fit check uses the letters and characters left after spaces are removed.
Are these platform limits official?
They reflect commonly documented limits at the time of writing, but platforms update them. Treat the result as a quick screen and confirm when you sign up.
