Roblox username rules
6 tips for a great Roblox username
Think about your game persona
Your Roblox username follows you across every game. Choose something representing how you want to be known — fighter, builder, or role-player.
Changes cost Robux
Unlike most platforms, changing your Roblox username costs 1,000 Robux (~$10). Take real time to find a name you will be happy with long-term.
Gaming names work best
Bold, action-oriented names like ShadowBlade or VoidHunter fit Roblox culture. Overly cute or professional names can feel out of place.
Place numbers strategically
If your name is taken, add a number in the middle or after a meaningful word. VoidX99 reads better than Void99.
Keep it under 15 characters
Roblox allows 20 but shorter names look cleaner in leaderboards, chats, and friend lists. Aim for 8–14.
Use underscores carefully
No spaces allowed — use one underscore to separate words: Shadow_Blade. One underscore maximum looks cleanest.
