What counts as a character

  • Usernames may use letters, numbers and underscores; no spaces, dots or hyphens.
  • The @ sign is not part of the count.
  • Display names can use spaces, accents and emoji.

Best length vs the maximum

  • Shorter handles are easier to mention: others have less to type and more room in their own posts.
  • Match your handle across platforms if you can; check Instagram’s limit of 30 and TikTok’s of 24.
  • Need ideas? The username generator makes 30 at a time and lets you set the length.
