Gaming Username Limits: PUBG vs Roblox vs Minecraft

None of PUBG, Roblox, or Minecraft let you style the name you actually log in with. All three restrict that field to plain letters, numbers, and (sometimes) underscores. Where a stylish name works is elsewhere on each platform, and that "elsewhere" is different for all three, which is the part most name generators skip.

PUBG

PUBG Mobile and BGMI have been widely reported to cap a name at 3 to 14 characters. PUBG on PC and console is more generous, at 4 to 16 characters, and explicitly allows underscores and hyphens; whether Mobile does is genuinely unconfirmed, with mixed player reports. Neither version accepts a literal space bar character in the name field, though a decorative Unicode character that renders as blank space is a common workaround. Full detail and a live character counter: the PUBG Name Generator.

Roblox

Roblox splits identity into two fields with two different rule sets:

Username (the permanent login): 3 to 20 characters, letters, numbers, and single underscores only. No Unicode, no spaces.
Display name (shown above your avatar, in every server): accepts the full Unicode range since 2021, capped at 20 characters. This is where a styled name actually goes.

The 20-character cap is not as generous as it sounds once you style something. A gothic or cursive letter still counts as one character against the cap, but a full-width (vaporwave-style) character counts as two, so a fully full-width display name gets you only about ten visible letters before you hit the limit. Try it: Roblox Name Generator.

Minecraft

Minecraft is the strictest of the three, and it does not offer a second, stylable field the way Roblox does:

Java Edition username: 3 to 16 characters, letters, numbers, and underscores only. No Unicode, no spaces, no punctuation.
Bedrock Edition: uses your Xbox Gamertag instead, up to 12 characters.
You can change either name once every 30 days from your Microsoft account page; the old name stays reserved for about 37 days before anyone else can claim it.

So where does a stylish Minecraft name actually go? Server nicknames (most servers running the Essentials plugin support a `/nick` command, subject to that server's own rules), renamed items and name tags applied from an anvil, and text on signs and in books. All of those accept special characters even though your account name never will. More on this split: Minecraft Name Generator.

The pattern across all three

Every platform here treats the account name as an identity anchor: locked down, plain-text, hard to fake. Styling lives in the display layer instead, wherever one exists. Before you build a name around a specific style, check which field you are actually filling in. A gorgeous 20-character vaporwave name is a great display name and an instant rejection as a Roblox username.

Frequently Asked Questions

How many characters can a PUBG username be?

It depends on the version. PUBG Mobile and BGMI are widely reported to cap names at 3 to 14 characters, though whether Mobile allows hyphens and underscores is genuinely unconfirmed across player reports. PUBG on PC and console allows 4 to 16 characters and explicitly permits underscores and hyphens. Neither version accepts a literal space character.

Can I use Unicode or special characters in my Roblox username?

Not in your login username. The @username field only allows letters, numbers, and single underscores — Unicode is rejected at account creation. Your display name is different: since 2021, it accepts the full Unicode range, capped at 20 characters. Note that full-width characters count as two towards that cap, so a fully styled display name runs out of room faster than plain text.

How often can you change your Minecraft username?

Once every 30 days, from your Microsoft account page. The old name stays reserved for roughly 37 days before another player can claim it. Bedrock Edition uses your Xbox Gamertag instead, which follows Xbox's own name-change policy.

Where can you use stylish Unicode text in Minecraft?

Not as your account name — Java Edition usernames are restricted to letters, numbers, and underscores. Stylish text does work in: server nicknames (via the /nick command on servers running the Essentials plugin, subject to that server's own rules), renamed items and name tags placed with an anvil, and text on signs and in books. All of those fields accept special characters even though your account name does not.

What is the difference between a Roblox username and a display name?

Your username is the permanent login identifier: 3 to 20 characters, letters, numbers, and underscores only, chosen at account creation. Your display name is what appears above your avatar and in servers: editable, up to 20 characters, and it accepts Unicode characters since 2021. The display name is where stylish text actually works on Roblox.
