Where sources disagree. One X help page says a username can be "up to 15 characters", another says "fewer than 15". In practice 15 is the accepted maximum; pick 14 or fewer if you want to be certain.
By account type
Free accounts
- Every limit in the table applies.
- You can change your display name at any time, per X username rules.
X Premium
- The same field limits apply.
- Premium accounts carry the blue checkmark, and changing your profile photo, display name or username triggers a fresh review before the checkmark returns, per X's verification help. Settle your profile before you subscribe.
Writing a profile that converts
- Name: your real name, plus a short word on what you do if it helps people place you.
- Bio: say who you help and how, in plain words, then add one proof point. Read more on the bio glossary page or browse founder bio examples.
- Pinned post: pin your best post or a short introduction so new visitors see your strongest work first. See pinned post.
- Images: a clear face for the profile photo and a header that says what you do. Use our banner templates.
Common mistakes
- A handle that is hard to spell. Underscores and digit swaps make you hard to find and tag.
- Changing your handle often. Old links and mentions stop pointing to you.
- Changing your photo or name on a verified account. The checkmark disappears until X reviews the change.
- A bio full of hashtags. Plain words read better and still turn up in search.
