Picking a Roblox username matters more than most people realize. Your username has to be 3 to 20 characters long, can only use letters, numbers, and at most one underscore, and it has to pass Roblox's strict text filter before the account is created. There are no periods, no spaces, and no symbols allowed, so the cleaner your idea, the more likely it gets accepted on the first try. The catch is that your username is hard to change later. Roblox charges Robux for a rename, and your old name still lingers in places, so it pays to choose something you actually like now. The good news is that Roblox also gives you a separate display name. This is the name people mostly see, it can be edited freely, and it can even repeat names other players already use. Display names are more flexible, but they are still filtered down to readable characters, which means heavy Unicode fonts and stacked symbols usually will not save there. Our advice is simple: lock in a clean, easy-to-type username, then add personality with a styled-but-simple display name. Browse the ideas below, copy-paste your favorites, and test them in Roblox before you commit.
Frequently asked questions
How do I change my Roblox username?+
Open Roblox in a browser or the app, go to Settings, and look for the Account Info section where you can edit your username. You will need to confirm your password, and the new name must follow the same rules: 3 to 20 characters using only letters, numbers, and one underscore.
Does changing my Roblox username cost Robux?+
Yes. Roblox charges Robux to change your username, so it is treated as a paid action rather than a free edit. Your display name, on the other hand, can be changed for free, which is why most players style their display name and leave the username alone.
What characters are allowed in a Roblox username?+
Roblox usernames can use letters (A-Z, a-z), numbers (0-9), and at most one underscore. Periods, spaces, and special symbols are not allowed, and the whole name has to be 3 to 20 characters and pass Roblox's text filter before it is accepted.
What's the difference between a username and a display name?+
Your username is your unique account handle used to log in, and it is hard and costly to change. Your display name is a separate label that appears above your character, can be edited freely, and is allowed to match names other players already use.
Why won't fancy fonts work in my Roblox name?+
Roblox filters names down to readable, standard characters for safety, so heavy Unicode fonts and stacked symbols usually get rejected or stripped. Light styling like small caps may sometimes pass in a display name, but the username field will not accept decorative fonts at all.
