In math, the square root of a number is a factor that, when multiplied by itself, results in the original number.

If you write about advanced mathematics, it can be helpful to know how to insert the square root symbol into a Word document. For additional math symbols, check out my articles on inserting the micro or approximately equal symbols into Word documents or take a look at our Microsoft Word courses.

Here are 6 ways you can insert a square root symbol in Microsoft Word.

## 1) Add the Square Root Symbol with the Symbol Dialog Box

You can easily insert the square root symbol using the Symbols dialog box. Click where you want the square root symbol to appear then do the following:

- Click the
**Symbol**button in the*Symbols*group on the*Insert*tab. - Select
**More Symbols**from the drop-down menu.*The Symbols dialog appears.* - Verify that the
*Symbols*tab is selected. Select**(normal text)**from the*Font*drop-down menu and**Mathematical Operators**from the*Subset*drop-down menu. - Select the
**Square Root**symbol (√), click the**Insert**button, then click**Close**.

## 2) Add the Square Root Symbol with Equation on the Insert Tab

Microsoft Word includes a feature that lets you enter complex mathematical formulas with ease. Here is how to add a square root symbol with the insert equation feature:

- Click the Equation button in the
*Symbols*group on the*Insert*tab (or press**Alt**+**=**).*An equation field is added to the document and the Equation tab appears on Word’s ribbon.* - Click the
**Square Root**symbol (or Radical Sign) from the Symbols gallery or type**\sqrt**then press the**space bar**in the equation field.

## 3) Add the Square Root Symbol Using an Alt Code Shortcut

You can insert the square root symbol by holding the **Alt** key while typing **251** on your numeric keypad.

Please note: the **Alt** + **251** shortcut only works if you have a full size keyboard with a numeric keypad. If you have a laptop with a compact keyboard, this shortcut likely won’t work for you.

## 4) Add a Keyboard Shortcut to Insert Square Root Symbol

You can create a custom keyboard shortcut to enter square roots with ease. This method involves a little set up but it’ll make typing the square root symbol so much easier!

Here’s what you do:

- Click the
**Symbol**button in the*Symbols*group on the*Insert*tab. - Select
**More Symbols**from the drop-down menu.

The Symbols dialog appears. - Verify that the
*Symbols*tab is selected. Select**(normal text)**from the*Font*drop-down menu and**Mathematical Operators**from the*Subset*drop-down menu. - Select the
**Square Root**symbol (√) then click the**Shortcut Key**button.*The Customise Keyboard dialog box appears.* - Press
**Ctrl**+**Alt**+**Q**(or another key combination) then click**Assign**. - Click
**Close**twice.

After completing this process, you press **Ctrl** + **Alt** + **Q** any time you want to type the square root symbol.

Ctrl + Alt + Q is a good keyboard shortcut to type square root because it’s not used for anything else.

## 5) Use AutoCorrect to Insert the Square Root Symbol

You can configure an AutoCorrect to substitute the square root symbol whenever a string of characters (like \sqrt) is typed.

Here is a quick way to add an entry for square root to AutoCorrect in Word.

- Click the
**Symbol**button in the*Symbols*group on the*Insert*tab. - Select
**More Symbols**from the drop-down menu.

The Symbols dialog box appears. - Verify that the
*Symbols*tab is selected. Select**(normal text)**from the*Font*drop-down menu and**Mathematical Operators**from the*Subset*drop-down menu. - Select the
**Square Root**symbol (√) then click the**AutoCorrect**button.*The AutoCorrect dialog box appears.* - Type
**\sqrt**in the Replace box then click**Add**then click**OK**. - Click
**Close**.

After completing this process, every time you type **\sqrt** then press the **space bar**, AutoCorrect will automatically replace the characters with the square root symbol.

## 6) Copy and Paste the Square Root Symbol

You can copy the square root symbol from another document or web page into your current Word document. If you don’t use the square root symbol often, this can be the easiest way to add it.

## Inserting the Square Root Symbol in Microsoft Word is Easy

Each of the techniques outlined in this article let you insert a square root symbol into a Microsoft Word document.

I think using an alt code shortcut to insert the square root symbol is the easiest option but it won’t work if you don’t have a numeric keypad. Use the shortcut that you find easiest to remember – and you’ll insert square root symbols like a pro!
