Platform character limits and rules
Different platforms have different username constraints. Twitter/X allows 4–15 characters (letters, numbers, underscores only). Instagram: 1–30 characters. Reddit: 3–20 characters (letters, numbers, underscores, hyphens). GitHub: 1–39 characters (letters, numbers, hyphens; no underscores). Discord: 2–32 characters. TikTok: 2–24 characters (letters, numbers, underscores, periods). This generator lets you set a maximum length and filter by allowed characters for your target platform.
| Platform | Max length | Allowed characters |
|---|---|---|
| Twitter/X | 15 | Letters, numbers, underscore |
| 30 | Letters, numbers, period, underscore | |
| GitHub | 39 | Letters, numbers, hyphen |
| 20 | Letters, numbers, underscore, hyphen | |
| Discord | 32 | Letters, numbers, underscore, period |
Tips for a memorable username
A good username is short, easy to type, and recognizable across platforms. Avoid numbers appended purely for availability (username123) as they look generic and are hard to remember. Instead, try combining a descriptor + noun (swiftcoder, quietpixel), initials + theme (jm_photo), or a portmanteau of your name and hobby. Keep it consistent across platforms for brand recognition — use a username-availability checker to find a handle you can claim everywhere before committing to it.
