Free, no sign-up, runs in your browser. Updated 2026-11-02.
The short answer
Instagram allows up to 30 characters in the username.
What counts toward the limit
Letters, numbers, periods and underscores only. No spaces and no other symbols.
How much people actually see
The username shows in full on your profile, but is shortened in some lists and notifications.
Tips for fitting your username
- Shorter is easier to remember and to say out loud. Aim well under the limit.
- Match your handle on other platforms where you can, so people find you easily.
- Avoid long strings of numbers or underscores, which look like spam accounts.
How this compares with other limits
| Platform | Field | Limit |
|---|---|---|
| Username | 30 | |
| TikTok | Username | 24 |
| X (Twitter) | Username | 15 |
Limits come from platform help pages and published guides, and platforms change them. Where it matters, confirm in the app. See every limit on the character limits hub.
Frequently asked questions
Can an Instagram username have spaces?
No. Use a period or an underscore instead.
Can I change my username later?
Yes, in Edit profile. Old links to the previous name may stop working.
Where can I check my text length for every platform at once?
Use the social media character counter, which shows the limit for each platform side by side.
