The quickest way to add a subscript in Google Docs

To write a subscript in Google Docs, highlight the text or number you want to make smaller and lower, then use the keyboard shortcut Ctrl + Comma (on Windows) or Cmd + Comma (on Mac). The selected text will immediately drop below the baseline and shrink. To undo it, select the text again and press the same shortcut.

If you prefer using the menu instead of a keyboard shortcut, you can go to Format in the top menu, then select Text, and click Subscript. This does the same thing but takes more clicks.

Subscripts are useful for chemical formulas (like H₂O), mathematical notation, and footnote references. The subscript stays attached to the text even if you edit around it, so you can keep working without it reverting to normal.

Key Takeaways

  • Use Ctrl + Comma (Windows) or Cmd + Comma (Mac) to instantly subscript highlighted text.
  • The Format menu offers the same subscript option if you do not remember the keyboard shortcut.
  • Superscript uses Ctrl + Period (Windows) or Cmd + Period (Mac) for exponents and citations.
  • You can mix subscripts and superscripts in the same document without affecting other formatting.

Using the Format menu when you prefer not to memorize shortcuts

Open your Google Docs document and highlight the character or word you want to subscript. Click Format in the menu bar at the top of the page. A dropdown will appear with several options.

Select Text from that dropdown. Another submenu will open showing Subscript and Superscript as options. Click Subscript. The highlighted text will immediately format as a subscript.

This method works identically to the keyboard shortcut but requires more steps. Many people use the menu the first few times, then switch to the keyboard shortcut once they remember it.

Superscript for exponents, citations, and footnotes

Superscript is the opposite of subscript — the text rises above the baseline instead of dropping below it. Use Ctrl + Period (Windows) or Cmd + Period (Mac) to apply superscript to highlighted text.

Superscript is common for mathematical exponents (like x²), trademark symbols (™), and footnote numbers. You can also access superscript through Format > Text > Superscript if you prefer the menu.

Like subscript, superscript formatting stays with the text when you edit your document, so you do not have to reapply it if you add or remove words nearby.

Removing subscript or superscript formatting

To remove subscript or superscript formatting, highlight the text that has the formatting applied. Press the same keyboard shortcut you used to apply it — Ctrl + Comma for subscript or Ctrl + Period for superscript on Windows (use Cmd instead of Ctrl on Mac). The text will return to normal size and position on the baseline.

Alternatively, go to Format > Text and click the subscript or superscript option again to toggle it off. Either method works equally well.

Combining subscripts and superscripts in the same document

You can use both subscript and superscript in the same document without any conflict. For example, you might write a chemical formula with a subscript (H₂O) in one sentence and an exponent with a superscript (2³) in the next. Each formatting applies only to the text you select, so they do not interfere with each other.

If you need both subscript and superscript on the same character or word — which is rare — you would need to apply one, then apply the other. Google Docs will layer them correctly, though the result can look crowded depending on the font size.

What happens when you copy and paste subscripted text

When you copy text with subscript or superscript formatting and paste it into another part of your document, the formatting comes along. The subscript or superscript stays applied to the text you pasted.

If you paste subscripted text into a different Google Docs document, the formatting also transfers. However, if you paste into a program outside Google Docs — like Microsoft Word or a plain text editor — the formatting may or may not survive depending on what program you are pasting into. Word usually preserves it; plain text editors will not.

Frequently Asked Questions

Can I make subscript or superscript text a different color?

Yes. Highlight the subscripted or superscripted text, then use the text color tool in the toolbar (the letter A with a colored line underneath). The color applies to the subscript or superscript just as it would to normal text. You can also change the color before applying the subscript or superscript formatting.

Does subscript work the same way on mobile Google Docs?

The keyboard shortcuts do not work on mobile devices. Instead, highlight the text, tap the three-dot menu, select Text, and then tap Subscript or Superscript. The process is slower than on desktop but produces the same result.

What if the keyboard shortcut is not working?

Check that you have the text highlighted before pressing the shortcut. If nothing happens, try using the Format menu instead — this confirms whether subscript is available in your document. Some older browsers or accessibility tools can interfere with keyboard shortcuts; switching browsers or using the menu is a reliable workaround.

Can I set a default subscript or superscript style for repeated use?

Google Docs does not have a built-in default subscript style, but you can create a custom paragraph style that includes subscript formatting. Go to Format > Paragraph styles > New style, apply subscript to the sample text, and save it. Then you can apply that style to any text in the future.
