What is Square Text?

Square text uses Unicode ‘Enclosed Alphanumerics Supplement’ (U+1F130 onwards) to display Latin letters inside square boxes. Two variants: outline squares (🄰 🄱 🄲) with the letter inside a hollow square, and filled squares (🅰 🅱 🅲) with white letter on a black square. Famous as the ‘blood type’ notation in Japan (🅰🅱🅾🆎 for blood types A, B, O, AB) and as the Twitch streaming aesthetic. The filled style especially is associated with bold, gamer-esque, urban graffiti looks. Use for: Twitch/YouTube channel branding, gaming clan tags, bold Instagram captions, brand initials in usernames, blood-type-style display (🅰+, 🅾-).

How to use this tool

1. Type your text — Letters convert to squared Unicode. A-Z (uppercase only).
2. Choose outline or filled — Outline = subtle, filled = bold attention-grabbing.
3. Copy text — Plain Unicode text — pastes anywhere.
4. Paste into bio/post — Twitter, Instagram, Discord, gaming platforms all support these.

Unicode square character ranges

Outline squares:

• Uppercase letters: U+1F130 to U+1F149 (🄰 to 🅉)
• 26 letters, A-Z
• Hollow square with letter inside

Filled squares (also called ‘negative squared’):

• Uppercase letters: U+1F170 to U+1F189 (🅰 to 🆉)
• Same 26 letters, but white-on-black
• More visually loud than outline

Special characters in this block:

• 🆎 (U+1F18E) = AB squared (blood type)
• 🆑 (U+1F191) = CL squared
• 🆒 (U+1F192) = COOL squared
• 🆓 (U+1F193) = FREE squared
• 🆔 (U+1F194) = ID squared
• 🆕 (U+1F195) = NEW squared

These are commonly used emoji from the same Unicode block.

Examples

• Blood type display: 🅰+ 🅱- 🅾+ 🆎-
• Twitch channel: 🅢🅣🅡🅔🅐🅜🅔🅡 🅛🅘🅥🅔
• Brand initials: 🅼🅵🅺 for ‘MFK Brand’
• Gaming clan: 🅴🅻🅸🆃🅴 🅲🅻🅰🅽
• Bold caption: 🅸🅼🅿🅾🆁🆃🅰🅽🆃 🅰🅽🅽🅾🆄🅽🅲🅴🅼🅴🅽🆃

Tips & best practices

• Use sparingly — entire posts in squares are hard to read
• Squared letters work best for usernames, brand tags, channel names
• Mix with regular text: prefix ‘🅽🅴🆆: My Latest Post’ for emphasis
• Don’t use for body content — designed for short label/badge use
• Filled squares display larger on most devices — better for mobile visibility
• Combine with category emoji: 🎮 🅶🅰🅼🅴🆁 🎮

Limitations & notes

Squared text is uppercase-only — no lowercase variants in standard Unicode block. Limited to 26 Latin letters; numbers and symbols stay regular. Some older devices (pre-2012 Android) render as boxes. Screen readers may struggle. Not suitable for body text or accessibility-critical content.

Frequently Asked Questions

Why no lowercase in square text?

Unicode designers only included uppercase squared letters in the Enclosed Alphanumerics Supplement block. Lowercase variants don’t exist as standard characters.

What’s the 🅰🅱🅾🆎 notation for?

Japanese blood type display convention — standardized in Unicode for mobile messaging. 🆎 is a single character (not separate 🅰 + 🅱), used in medical/personal contexts in Japan.

Can I use square text in Twitch usernames?

Twitch usernames require Latin alphanumeric only — can’t use Unicode squares. But you CAN use them in display name, channel description, panels, and chat messages.

Do filled squares look like emoji?

On iOS/Apple, filled squares render with rounded corners and color (more emoji-like). On Windows/Android, they’re more rectangular and monochrome. Both are valid renderings.

Are 🆒 🆓 🆔 🆕 emoji or text?

Both — they’re in the Unicode block but classified as emoji on most platforms (with full color rendering). Treat as emoji for usage purposes.

Can I use square text in Discord usernames?

Yes — Discord allows Unicode in usernames including squared letters. Limit: 32 characters total. Squared letters count as one character each.

Why does my square text show different sizes?

Squared letters are slightly wider than regular letters in most fonts. Mixing both creates uneven spacing. For consistent look, use all-squared text rather than mixing.
