Twitch profile specs
Twitch usernames are 4–25 characters and the profile banner is 1200 × 480. The bio (the About panel) allows 300 characters and supports basic formatting.

Where it usually goes wrong
- A username under 4 characters — Twitch rejects it
- A banner with small text; it's displayed much narrower on mobile
- Leaving the About panel empty; it's the first thing a new viewer reads
Skip the guesswork
SetMySocial writes your Twitch bio to exactly 300 characters, checks whether the username is free, and exports the picture and cover at the right size.
