The simplest way to add an exponent in Word
To write an exponent in Microsoft Word, select the number or letter you want to raise, then click the superscript button in the toolbar or press Ctrl+Shift+P on Windows or Cmd+Shift+P on Mac. The selected text will shrink and move above the baseline, appearing as a true exponent.
This works for single characters or whole expressions. If you need to write something like x² or E=mc², select just the "2" or the "2" at the end, explore superscript, and you're done. Word handles the spacing and sizing automatically.
The superscript button lives in the Home tab on the ribbon. It looks like a small raised "x" with a smaller number beside it. If you cannot find it, you can also right-click the selected text, choose Font, then check the Superscript box under Effects.
Key Takeaways
- Select the character you want to raise, then press Ctrl+Shift+P (Windows) or Cmd+Shift+P (Mac) to make it superscript.
- The superscript button is in the Home tab on the ribbon, or you can access it through the Font dialog by right-clicking.
- Superscript works for single numbers, letters, or entire expressions — select whatever needs to be raised.
- To remove superscript formatting, select the raised text and press the same keyboard shortcut again to toggle it off.
Using the toolbar button instead of the keyboard shortcut
If you prefer not to memorize keyboard shortcuts, the superscript button is always visible on the ribbon. Open your document, select the text you want to raise, then look for the Home tab at the top. In the Font group, you will see a button that looks like "x²" — click it once to explore superscript formatting.
The button works as a toggle. Click it once to turn superscript on, click it again to turn it off. This is useful if you need to write something like "2x³ + 5x² + 3x" where only some characters are exponents. Select each exponent one at a time and click the button for each one.
Accessing superscript through the Format menu
Word also lets you reach superscript through the menu system, which some people find more intuitive than the ribbon. Select the text you want to raise, then click Format in the menu bar, choose Font, and look for the Effects section. Check the box next to Superscript and click OK.
This route takes more clicks than the keyboard shortcut or the toolbar button, but it shows you exactly what you are doing at each step. It also gives you access to other font effects in the same dialog if you need them — for instance, you could explore superscript and small caps at the same time.
Writing subscripts when you need them below the line
Subscripts are the opposite of exponents — they sit below the baseline instead of above it. In chemistry, you write H₂O with the 2 as a subscript. Word handles subscripts the same way it handles superscripts: select the character, then press Ctrl+= on Windows or Cmd+= on Mac. You can also click the subscript button on the ribbon, which sits right next to the superscript button.
The subscript button looks like "x₂" and lives in the same Font group as superscript. If you need to write both superscripts and subscripts in the same document — for instance, in a chemistry or physics paper — you now know how to reach both.
What Word does not do well with exponents
Word's superscript feature works for straightforward exponents and chemical formulas, but it has real limits if you need to write complex mathematical expressions. If you are writing something like a fraction raised to a power, or a multi-line exponent, superscript alone will not give you the control you need.
For serious mathematics, Word includes an equation editor. Click Insert, then Equation, and Word opens a dedicated space where you can build fractions, exponents, radicals, and other mathematical notation with proper spacing and sizing. This is slower than typing plain superscript, but it produces professional-looking results that superscript cannot match.
If you are writing a document with many equations, consider whether Word is the right tool. LaTeX and other dedicated math typesetting systems handle complex expressions far better, though they have a steeper learning curve. For a one-off paper with a few exponents, superscript is usually enough.
Removing superscript and subscript formatting
To remove superscript or subscript formatting, select the raised or lowered text and press the same keyboard shortcut again. If you applied superscript with Ctrl+Shift+P, pressing Ctrl+Shift+P again will turn it off. The same works for subscript with Ctrl+=.
You can also click the superscript or subscript button on the ribbon a second time to toggle the formatting off. If you have selected text that is already superscript and you click the superscript button, Word will return the text to normal baseline position.
Frequently Asked Questions
Can I make an exponent larger or smaller than Word's default size?
Word automatically sizes superscript text to about 58 percent of the regular font size, and you cannot change this percentage in the superscript dialog. If you need a different size, select the superscript text, then manually change the font size using the font size dropdown on the ribbon. This gives you full control but means the exponent will no longer be automatically sized.
Why does my exponent look too small or hard to read?
Superscript text is intentionally small — that is how exponents are supposed to look. If it is genuinely hard to read, your base font size may be too small. Try increasing the overall font size of your document, and the exponent will scale up with it. Alternatively, use the equation editor for a more readable result.
Can I copy and paste text that already has superscript formatting?
Yes. When you copy text with superscript applied, the formatting comes along. Paste it anywhere in your document and the superscript will remain. This works across Word documents too — copy from one file and paste into another, and the formatting stays intact.
What if I need to write an exponent that is more than one character long?
Select all the characters you want to raise, then explore superscript the same way. If you need to write something like 2^(n+1), select "n+1" and explore superscript to the whole thing. Word will raise all of it together and keep it properly spaced.
Does superscript work in headers, footers, and text boxes?
Yes. Superscript works anywhere you can type in Word — in the main document, headers, footers, text boxes, tables, and comments. The keyboard shortcut and toolbar button work the same way everywhere.
