The fastest way to add the pi symbol (π) in Word for Microsoft 365 on Windows is to type 03C0 and press Alt + X. Word turns the code into π. You can also press Alt + = to insert an equation, type \pi, and press Space. Or go to Insert > Symbol > More Symbols, choose the Greek and Coptic subset, and insert π. On a Mac, press Option + P.
Below are all the methods, including how to get a capital Π, create a shortcut, and type π outside Word.
Quick reference
| Method | Lowercase π | Uppercase Π |
|---|---|---|
| Unicode + Alt X (Word, Windows) | 03C0, then Alt + X | 03A0, then Alt + X |
| Equation (Alt + =) | \pi then Space | \Pi then Space |
| Alt code (number pad) | Alt + 227 | Not available in the basic set |
| Mac | Option + P | Option + Shift + P |
| Windows symbol panel | Windows + . > Ω > Greek | Same |
Method 1: Alt + X shortcut
- Click where you want π.
- Type 03C0.
- Press Alt + X.
If the character just before the code is a letter A–F or a number, Word may read it as part of the code. Type a space first, then remove it after.
Method 2: Insert Symbol
- Click Insert > Symbol > More Symbols.
- Set Font to (normal text) and Subset to Greek and Coptic.
- Click π and click Insert. Or type 03C0 in Character code.

After you use it once, π appears in the Insert > Symbol drop-down for one-click access.
Method 3: Equation editor
- Press Alt + = (or Insert > Equation).
- Type \pi and press Space.
This is best for math documents, since Word formats π in a math font along with the rest of your equation, like A = πr².
Method 4: Use Math AutoCorrect everywhere
- Go to File > Options > Proofing > AutoCorrect Options.
- Click the Math AutoCorrect tab.
- Check Use Math AutoCorrect rules outside of math regions, then click OK.
Now typing \pi followed by a space inserts π anywhere in your document.
Method 5: Create a keyboard shortcut
- Open Insert > Symbol > More Symbols and select π.
- Click Shortcut Key, press a combination like Alt + P, and click Assign.
Pi in other apps
- Any Windows app: Press Windows + ., open the Ω tab, and look in Greek symbols.
- Google Docs: Insert > Special characters, search “pi.”
- Excel: Use =PI() for the value 3.14159…, or insert the π character as text with Insert > Symbol.
- iPhone and Android: Gboard includes π on its second symbols page (tap ?123, then =\<). The standard iPhone keyboard doesn’t have π, so paste it once and save it as a Text Replacement in Settings > General > Keyboard.

Frequently asked questions
Why does my π look different from the rest of the text?
Equation mode uses the Cambria Math font. To match your text, use the Alt + X method instead of an equation.
Can I use the Symbol font trick?
In older versions, typing p and switching the font to Symbol shows π. This can break if the file is opened on another computer or converted, so Unicode methods are better.
How do I type π on a Mac in Word?
Press Option + P. It works in all Mac apps.
