Method 1: Type the Beta Symbol on Windows Using Alt Code

On Windows, you can type the lowercase beta symbol using an Alt code.

The common Alt code for lowercase beta is:

Alt + 225

This can work in many Windows apps, including Microsoft Word, Excel, PowerPoint, Notepad, and some text boxes.

Steps to type β on Windows

Click where you want to insert the beta symbol.
Turn on Num Lock.
Hold down the Alt key.
While holding Alt, type 225 using the numeric keypad.
Release the Alt key.

You should get: β

Important note about Alt codes

Alt codes usually require the numeric keypad on the right side of the keyboard.

The number row above the letters may not work.

So this should work:

Alt + 225 using the numeric keypad

But this may not work:

Alt + 225 using the top number row

What if my laptop has no numeric keypad?

If your laptop does not have a numeric keypad, use one of these methods instead:

Copy and paste β
Use Microsoft Word’s Unicode shortcut: 03B2, then Alt + X
Use Insert Symbol in Word, Excel, or PowerPoint
Use Windows Character Map
Use Google Docs Special characters

Method 2: Type the Beta Symbol in Microsoft Word

Microsoft Word gives you several reliable ways to insert the beta symbol.

The best methods are:

Use the Unicode shortcut: 03B2, then Alt + X
Use Insert > Symbol
Use the Equation tool
Use the Windows Alt code
Copy and paste the symbol

Option A: Use the Word Unicode Shortcut

This is one of the best ways to type the beta symbol in Microsoft Word on Windows.

The Unicode for lowercase beta is:

03B2

Steps

Open Microsoft Word.
Click where you want the beta symbol.
Type 03B2.
Press Alt + X.

Word will convert 03B2 into: β

For uppercase beta

The Unicode for uppercase beta is:

0392

To type uppercase beta in Word:

Type 0392.
Press Alt + X.

You should get: Β

Remember, uppercase beta may look like a normal capital B, but it is a different Unicode character.

Option B: Use Insert Symbol in Word

You can also insert beta from Word’s Symbol menu.

Steps

Open Microsoft Word.
Click where you want the beta symbol.
Go to the Insert tab.
Click Symbol.
Click More Symbols if needed.
In the font box, choose normal text or a common font.
In the subset box, choose Greek and Coptic.
Find and select β.
Click Insert.
Click Close.

This method is good if you do not want to remember any code.

Tip: After you insert beta once, Word may show it under recently used symbols, making it easier to insert again later.

Option C: Use the Equation Tool in Word

If you are writing a formula, the Equation tool may be the best option.

Steps

Open Microsoft Word.
Go to the Insert tab.
Click Equation.
Type \beta inside the equation box.
Press Space.

Word should convert it into:

This method is especially useful when beta is part of a mathematical equation.

Example

Type this inside a Word equation:

\beta

Then press Space.

You get:

Option D: Use Alt + 225 in Word

You can also use the Windows Alt code inside Word.

&beta; = 0.75

Result:

β = 0.75

Uppercase beta

Β

Example:

&Beta;

Decimal HTML code

Method 16: Type Beta in LaTeX

If you are writing in LaTeX, use:

\beta

This gives:

For uppercase beta, LaTeX usually uses the normal capital letter B, because uppercase beta looks like the Latin capital B in many fonts.

Lowercase Beta β vs Uppercase Beta Β

There are two beta characters:

Symbol	Name	Unicode
β	Greek small letter beta	U+03B2
Β	Greek capital letter beta	U+0392

The lowercase beta β is the one most people are looking for.

The uppercase beta Β looks like the English capital letter B in many fonts.

That means these two may look the same:

B and Β

But they are not the same character.

B is the Latin capital letter B.
Β is the Greek capital letter beta.

For most normal documents, if you need uppercase beta and appearance is all that matters, a normal capital B may look the same. But in technical, scientific, coding, or Unicode-sensitive work, use the real Greek uppercase beta Β.

Common Uses of the Beta Symbol

The beta symbol is used in many fields.

In mathematics

Beta can be used as a variable in equations and formulas.

Example:

β = 2x + 5

In statistics

Beta is often used for coefficients in regression models.

Example:

β₁ = 0.45

In finance

Beta can measure how much an investment moves compared to the market.

In software

Beta can mean a test version of software before the final release.

Troubleshooting: Beta Symbol Not Working

If you cannot type the beta symbol, here are the common problems and fixes.

Problem 1: Alt + 225 is not working

This usually happens because the numeric keypad is not being used.

Fix

Use the numeric keypad on the right side of the keyboard, and make sure Num Lock is turned on.

If your laptop does not have a numeric keypad, use:

Copy and paste β
Word Unicode shortcut: 03B2, then Alt + X
Insert Symbol
Character Map
Google Docs Special characters

Problem 2: I typed 03B2 but it did not change into β

The 03B2 + Alt + X method works mainly in Microsoft Word on Windows.

It may not work in every app.

Fix

Use it inside Microsoft Word, or use copy and paste in other apps.

Problem 3: Uppercase beta looks like B

This is normal.

The uppercase beta symbol Β often looks like the English capital letter B.

They are different Unicode characters, but many fonts display them almost the same way.

Problem 4: Beta appears as a box or strange character

This usually means the font or app does not support the character properly.

Fix

Try changing the font to a common font such as:

Arial
Calibri
Times New Roman
Cambria
Helvetica
Verdana

Problem 5: I need beta in an equation, not normal text

If you are writing a formula in Word or PowerPoint, use the Equation tool.

Inside the equation box, type:

\beta

Then press Space.

This gives a better math-style beta symbol.
