How to Type Square Root Symbol in Word: 3 Easy Methods

To type square root symbol in Word, use the Equation Editor, the \sqrt equation shortcut, or the Unicode code 221A. If you use shortcuts often, the Microsoft Word Keyboard Shortcuts Cheat Sheet is worth keeping open.

In this guide, you’ll learn three reliable ways to add a square root symbol, format a proper radical, and fix the common problems that stop the symbol from appearing correctly.

What Is the Square Root Symbol in Word?

The square root symbol (√) is a mathematical radical used to show that a number or expression sits under a square root. In Microsoft Word, you can insert it as a plain symbol or as a full equation structure with a bar over the number.

It is commonly used in:

• Maths assignments and worksheets
• Scientific and engineering reports
• Statistics, finance, and research documents
• Formal documents that also need clean equation formatting — see the guide on how to write fractions in Word.

For quick typing, Unicode is enough. For professional maths layout, use Word’s Equation Editor.

How to Type Square Root Symbol in Word: Step-by-Step

There are three practical ways to type square root symbol in Word. Use the Equation Editor for proper maths formatting, \sqrt for speed, or Unicode when you only need the √ character.

Method 1: How to Type Square Root Symbol in Word Using the Equation Editor

Use this method when you want the most professional result. Word creates a proper radical with a placeholder box and a horizontal bar that adjusts to the number or expression underneath.

Step 1: Open the Equation Editor

1. Place your cursor where you want the square root symbol to appear.
2. Press Alt + =.

👉 Word opens a new equation field and shows the Equation tab on the ribbon.

Step 2: Insert the Square Root Template

1. Go to the Equation tab.
2. Click Radical.
3. Select the first option, Square Root.
4. Type your number inside the placeholder box.

Example:

√100

👉 You now have a clean square root equation. This is the best method for assignments, reports, and anything that needs proper mathematical formatting.

Method 2: How to Type Square Root Symbol in Word With the \sqrt Shortcut

This is the fastest equation method. No menus. No clicks. Just the equation shortcut.

Steps:

1. Press Alt + = to open an equation field.
2. Type \sqrt.
3. Press Spacebar.
4. Type the number inside the placeholder.

Example:

√25

👉 Word instantly converts \sqrt into a square root structure. This is the fastest method by far if you already work inside equations.

Method 3: How to Type Square Root Symbol in Word Using Unicode

Use Unicode when you only need the plain √ symbol, not a full equation. This works well for quick notes, simple examples, and short technical labels.

Steps:

1. Type 221A.
2. Press Alt + X.

Word converts the code into:

√

👉 Done. The Unicode method inserts the symbol only, so it is not ideal for longer equations — but it is perfect when you need a quick standalone square root character.

Which Method Should You Use?

All three methods work. The right one depends on whether you need speed, proper equation formatting, or a plain symbol.

Method	Best For	Speed	Result
Equation Editor	Professional maths documents	Medium	Full radical structure
\sqrt shortcut	Fast equation typing	Fastest	Full radical structure
Unicode 221A	Plain symbol only	Fast	Standalone √ character

If you write equations regularly, use Method 2. If you are formatting a formal maths document, use Method 1. If you only need the symbol, use Method 3.

Common Problems When Typing Square Root Symbol in Word

If you cannot type square root symbol in Word correctly, one of these four issues is usually the cause.

The \sqrt Command Does Not Convert

The \sqrt shortcut only works inside an equation field. Press Alt + = first, then type \sqrt and press Spacebar.

Alt + X Does Not Change 221A Into a Symbol

Make sure the cursor is directly after 221A before pressing Alt + X. If other text is selected, Word may convert the wrong characters.

The Square Root Bar Is Too Short

A plain √ symbol will not stretch over numbers. Use the Equation Editor or \sqrt shortcut if you need a proper radical bar over a longer expression.

The Symbol Looks Different in Another Font

Different fonts draw the √ character slightly differently. Use Word’s equation formatting for consistent output, especially before exporting or sharing a document — and for final document layout, see how to change line spacing in Word.

Pro Tips

• Use \sqrt inside the Equation Editor if you write maths often. It is the fastest repeatable method.
• Use Unicode only for the standalone √ symbol. It does not create a full equation structure.
• Keep equation formatting consistent across your document. Avoid mixing plain symbols and full radicals in the same worksheet.
• Build longer technical documents with headings and navigation — see the guide on how to create a table of contents in Word.

Conclusion

Typing square root symbol in Word is simple once you know which method fits the job. Use the Equation Editor for polished maths, \sqrt for speed, and Unicode for the plain √ character.

If you create maths worksheets, scientific reports, or technical documents often, learn the equation shortcut first. Then pair it with the Microsoft Word Keyboard Shortcuts Cheat Sheet so your formatting stays fast and consistent.
