Tips for picking the perfect username

  • Keep it short — under 15 characters is ideal. Shorter usernames are easier to remember and tag.
  • Stay consistent — use the same username on all platforms. Inconsistency makes you harder to find.
  • Avoid numbers as fillers — adding "123" at the end signals a taken name. Try a word variation instead.
  • Skip special characters — periods and underscores work, but mixing them (e.g., _alex.dev_) gets confusing.
  • Test it out loud — say "find me at [username]". If it's unclear how to spell it, it's too complex.
  • Check the domain — if you might build a website, also check if the .com or .io domain is available.
