**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](https://help.x.com/en/managing-your-account/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](https://help.x.com/en/managing-your-account/about-x-bluecheck). 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](https://trygrowx.app/glossary/bio) or browse [founder bio examples](https://trygrowx.app/bios/founder).
- **Pinned post:** pin your best post or a short introduction so new visitors see your strongest work first. See [pinned post](https://trygrowx.app/glossary/pinned-post).
- **Images:** a clear face for the profile photo and a header that says what you do. Use our [banner templates](https://trygrowx.app/x-specs/banner-size).

## 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.

## Frequently asked questions
