How to Type the Squared Symbol (²) on Your Keyboard (2024)

The square is one of the most common mathematical operations, but how do you write the squared symbol (²) on your computer or mobile phone? Like many mathematical symbols such as the infinity symbol, the squared symbol is noticeably absent from standard computer keyboards.

In algebra, “to square” is to multiply a number by itself. For example, the square of 5 is 25 because 5 multiplied by 5 equals 25.

5² = 25

Inversely, the square root is the value that, when multiplied by itself, gives the original number. For example, the square root of 16 is 4 because 4 multiplied by 4 equals 16.

√16 = 4

While the squared symbol is one of the most frequently used symbols in mathematics, you’ll be hard-pressed to find it on your Windows or Mac keyboard. That’s because superscript and subscript symbols, unfortunately, are not included in standard keyboard layouts.

To incorporate superscript symbols such as the square root, you’ll have to type it via keyboard shortcuts and software such as the Character Map in Windows. Microsoft Word and Google Docs also provide the option to directly insert the square root sign without the need for shortcuts.

In this article, we’ll teach you how to type the squared symbol (a.k.a. “small 2”) on your computer or smartphone, be it on a word processor like Microsoft Word or in your emails and online conversations. You will be amazed at how easy it is to type the symbol.

Copy and Paste the Squared Symbol

If you can’t be bothered to type the squared symbol manually, you can just copy it from this page. All you have to do is to click the box below and the squared sign will be instantly copied to your clipboard, ready for pasting into your document.

Paste your copied symbol into your document or application by right-clicking and selecting Paste. You can also tap Ctrl + V to paste it. If you’re on mobile, just long-press and select Paste.

Type the Squared Symbol on a Windows Keyboard

The easiest way to type the squared symbol is by holding the Alt key while typing 0178 on the number pad. Make sure that Num Lock is turned on for this keyboard shortcut to work. Typing the keyboard shortcut using conventional number keys (outside the numeric keypad) will not work – you must use the number pad on the right side of your keyboard.

So the keyboard shortcut for the squared symbol is Alt + 0178. The result is like this: ².

Here’s a step-by-step guide on how to type the squared symbol using a Windows keyboard:

1. Place the cursor or insertion point where you want the superscript ² to appear in your document or application.
2. Activate the numeric keypad or number pad by tapping the Num Lock key.
3. Press and hold the Alt key.
4. While pressing the Alt key, type the 0178 keys on the numeric keypad.
5. Check the correct symbol has been inserted into your document.

The beauty of this method is that it works for almost any application including Notepad, Google Chrome and Microsoft Word. As long as your keyboard has a numeric keypad or number pad, you can type the squared sign via the keyboard shortcut. But if your keyboard doesn’t have a numeric keypad, you can insert the squared symbol by copying the symbol from this page or by using the Character Map.

Insert the Squared Symbol in Microsoft Word

Most of us use Microsoft Word and other word processing software to draft our documents and correspondences. The good news is that these word processors have support for special characters like the superscript symbol (x²), so you don’t have to memorize any keyboard shortcuts for these symbols.

1. Open the Word document where you’d like to place the symbol.
2. Under the Home tab, click the superscript button (x²).

4. The superscript ² has been inserted in your document. To return to normal typing, just click the superscript button (x²) once more.

You can also type 2 first and then select or highlight it before clicking the superscript (x²) button.

Alternatively, you can use the keyboard shortcut Ctrl + Shift + + (hold the Ctrl and Shift keys and then press the + key) to get the same result as clicking x².

Take note that this keyboard shortcut only works in Microsoft Word. Using it on the Chrome browser will zoom the window instead, so be careful with this.
