How to Type the Square Root Symbol on a Keyboard
Need to type the square root symbol yourself? Here are the shortcuts for every major platform.
On a Windows Keyboard
The most reliable method on a Windows PC is using an Alt code. This requires a keyboard with a numeric keypad.
- Hold down the Alt key and type 251 on the numeric keypad, then release Alt.
If you don't have a numpad, you can use the Windows Character Map utility to find and copy the symbol.
On a Mac Keyboard
Typing the square root symbol on macOS is very simple:
- Press Option + v.
On a Phone Keyboard (iPhone & Android)
Finding the square root symbol on a mobile device is easy once you know where to look.
- On iPhone: Switch to the number keyboard (123), then press and hold the zero key (0). A pop-up menu will appear with the √ symbol.
- On Android (Gboard): Switch to the symbol keyboard (?123), then go to the secondary symbol page (=\<). The √ symbol will be there.
About the Square Root Symbol (√)
The square root symbol √, also known as the radical sign, is a fundamental symbol in mathematics. It is used to indicate the square root of a number. For example, √9 = 3 because 3 × 3 = 9.
While this page provides the text symbol for copy-pasting, some users search for a "square root PNG". A PNG is an image file, which is not text. The text symbol √ is far more versatile because it can be used in any text field, scales perfectly with your font, and can be colored just like any other character. For documents, social media, and maths homework, the text symbol is the best choice.
