The √ symbol is plain Unicode text (U+221A). It pastes as a regular character, displays in every modern font, and works in every application that handles text.

Does It Work in Every App?

Yes. Because √ is a standard Unicode character it works in:

  • Microsoft Word, Excel, PowerPoint
  • Google Docs, Sheets, Slides
  • Gmail, Outlook, Apple Mail
  • Slack, Teams, Discord, WhatsApp
  • All browsers — Chrome, Firefox, Safari, Edge
  • Code editors — VS Code, Notepad, TextEdit
  • Social media — X/Twitter, LinkedIn, Facebook

Why Copy-Paste Instead of Typing?

There is no dedicated √ key on any keyboard. The fastest method depends on your device:

Tip: If you need √ frequently, bookmark this page for one-click access. The Copy button works on desktop and mobile.

What Does the Square Root Symbol Look Like?

The square root symbol (√, also called the radical sign or radix) has a tick on the left and a horizontal bar extending to the right over the expression. In plain text — like this page — only the tick portion (√) is used. In typeset mathematics, the bar extends the full width of the expression underneath.

Frequently Asked Questions

Will this paste into social media fields?

Yes. Twitter/X, LinkedIn, Instagram captions, Facebook posts, and WhatsApp all support Unicode characters including √. Paste normally with Ctrl+V or Cmd+V.

Does the font affect whether √ displays correctly?

Rarely. Most modern fonts — Arial, Times New Roman, Calibri, Georgia, system UI fonts — include √. If a very niche decorative font omits it, the operating system falls back to a system font automatically.

Is √ the same as a checkmark?

No. The square root symbol (√ U+221A) and the checkmark (✓ U+2713) are different Unicode characters. They can look similar at small sizes but are distinct. For a checkmark, use ✓ or ✔.

How do I type √ on mobile?

Copy-paste is the easiest method on mobile — tap Copy √ above, then paste. On iPhone you can also long-press the keyboard and search “radical” in the special characters section. On Android, use the Gboard emoji keyboard symbol search.
