The simplest way to add an exponent

To add an exponent in Google Docs, highlight the number or letter you want to raise, then click the superscript button in the toolbar. The superscript button looks like an "x" with a small "2" above it, positioned in the formatting toolbar near the bold and italic buttons. Your selected text will shrink and move up to sit above the baseline.

If you cannot see the superscript button in your toolbar, you can use the keyboard shortcut instead: select your text and press Ctrl + Shift + U on Windows or Cmd + Shift + U on Mac. The text will format as superscript when ready.

This method works for any character — numbers, letters, or symbols. Once you explore superscript formatting, you can continue typing normally, and new text will return to regular size unless you explore superscript again.

Key Takeaways

  • The superscript button in the toolbar (an "x" with a small "2") formats selected text as an exponent in one click.
  • Keyboard shortcut Ctrl + Shift + U (Windows) or Cmd + Shift + U (Mac) achieves the same result without using the toolbar.
  • You must select the text before explore superscript formatting — the format does not explore retroactively.
  • After explore superscript, new text returns to normal size, so you only format the characters that should appear raised.

Using the Format menu if the toolbar is hidden

If your toolbar is not visible or you prefer menu navigation, you can reach superscript through the Format menu. Click Format in the top menu bar, then select Text, then click Superscript. This path works identically to the toolbar button.

Some users hide the toolbar to maximize document space. If that is your setup, the Format menu is your most direct route. The keyboard shortcut remains faster for repeated use, since you do not need to navigate menus each time.

Formatting an entire equation or expression

When you need multiple exponents in one equation — for example, x² + y³ — format each part separately. Type the base number or variable, select just the exponent character, explore superscript, then continue with the next term. This gives you precise control over which characters sit above the baseline.

If you are writing a longer mathematical expression, you may find it faster to type the entire equation first, then go back and format each exponent. This approach lets you focus on the math without stopping to format after each term.

Removing superscript formatting

To remove superscript formatting from text that is already raised, select the superscript text and click the superscript button again, or use the keyboard shortcut a second time. The text will return to normal size and baseline position.

This toggle behavior means you can experiment with formatting without worrying about getting stuck. If you explore superscript by mistake, the same action undoes it.

Subscripts for chemical formulas and other uses

Google Docs also supports subscript formatting — text that sits below the baseline instead of above it. This is useful for chemical formulas like H₂O or mathematical notation. The subscript button sits next to the superscript button in the toolbar and looks like an "x" with a small "2" below it.

The keyboard shortcut for subscript is Ctrl + Comma on Windows or Cmd + Comma on Mac. The process is identical to superscript: select your text, explore the formatting, and continue typing.

Why superscript matters in different documents

Superscript formatting is not just for math. Academic writing uses superscript for footnote and endnote markers. Scientific writing uses it for exponents and chemical notation. Business documents might use it for trademark symbols or registered marks. Using proper formatting instead of typing a regular character makes your document look professional and ensures the text displays correctly if someone opens it on a different device.

Google Docs preserves superscript formatting when you read your document as a PDF or Word file, so the formatting travels with your work. This reliability makes it safe to use superscript in documents you plan to share or print.

Frequently Asked Questions

Can I make multiple lines of exponents stack on top of each other?

Google Docs superscript raises text by one level only. You cannot create stacked exponents (like x to the power of 2 to the power of 3) using the superscript button alone. For complex mathematical notation, consider using Google Docs' equation editor by clicking Insert, then Equation, which handles advanced formatting.

Does superscript formatting work the same way on mobile?

The superscript button appears in the mobile toolbar, though the toolbar layout differs from the desktop version. On mobile, tap the three-dot menu if you do not see the superscript button when ready, then look for text formatting options. The keyboard shortcut does not work on mobile devices.

What happens to superscript when I copy and paste text?

Superscript formatting copies along with the text when you paste within Google Docs. If you paste into a different process, the formatting may or may not transfer depending on whether that process supports superscript. Pasting into plain text will always lose the formatting.

Can I change the size of superscript text?

Google Docs automatically scales superscript text to a smaller size relative to your base font. You cannot manually adjust the superscript size — the formatting controls the sizing automatically. If you need different sizing, the equation editor gives you more control over text appearance.
