### Tips for Choosing a Great Username

- **Keep it under 15 characters** — shorter handles are easier to remember and fit all platforms
- **Avoid special characters** — stick to letters, numbers, and underscores for maximum compatibility
- **Make it memorable and brand-relevant** — your username should reflect who you are or what you do
- **Check for trademark conflicts** — avoid names that could cause legal issues down the line
- **Consider SEO** — including a niche keyword (e.g., "janefitness") can boost discoverability

## X Username Rules (2026)

X handles can be **4-15 characters** long and can only contain letters, numbers, and underscores. No periods, hyphens, or spaces are allowed. Handles always display with a lowercase **@** prefix.

The 15-character limit is the shortest of any major platform, so you may need to get creative. Usernames are **not case-sensitive** — @JohnDoe and @johndoe are the same.

You can change your X handle at any time through Settings, but your old handle becomes **immediately available** to others. Change during low-traffic hours to minimize the risk of someone snatching your old handle.

## Why Your X Handle Matters

Your X handle is how people **tag, mention, and find you** on the platform. A short, memorable handle makes it easier for others to include you in conversations, which drives more visibility and engagement.

On X, where every character counts (280 limit), a **shorter handle** means more room for the actual message when someone mentions you. This makes short handles especially valuable.
