X profile specs
X has the tightest handle limit of any major platform: 15 characters. The header is 1500 × 500 but the profile picture sits over its bottom-left corner on most layouts, so keep that region clear.

|---|---|
| Handle / username | 15 characters |
| Display name | 50 characters |
| Bio | 160 characters |

Where it usually goes wrong
- A handle over 15 characters — it simply won't be accepted
- Putting text or a logo in the bottom-left of the header where the avatar covers it
- A bio that relies on line breaks; X collapses them in most views
Skip the guesswork
SetMySocial writes your X bio to exactly 160 characters, checks whether the username is free, and exports the picture and cover at the right size.
