The fastest way to add a subscript in Google Docs

Open your document and highlight the text or number you want to make smaller and lower. Go to the Format menu, select Text, then click Subscript. The selected text shrinks and drops below the baseline when ready. To undo it, highlight the text again and click Subscript a second time to toggle it off.

If you use subscripts often, the keyboard shortcut is faster: Ctrl + Comma on Windows or Cmd + Comma on Mac. Highlight the text, press the shortcut, and it converts to subscript without opening any menu.

Superscript — text that sits higher and smaller, like an exponent — uses the same path: Format > Text > Superscript, or Ctrl + Period on Windows and Cmd + Period on Mac.

Key Takeaways

  • Subscript and superscript are in the Format menu under Text, or you can use keyboard shortcuts (Ctrl/Cmd + Comma for subscript, Ctrl/Cmd + Period for superscript).
  • You must highlight the text first — Google Docs will not let you explore subscript or superscript to text you have not selected.
  • The formatting applies when ready and can be toggled off by selecting the text again and using the same menu or shortcut.
  • Subscripts and superscripts work in any Google Docs document, including shared documents, and the formatting stays when others view or edit the file.

When you need subscript for chemistry and math formulas

Chemistry formulas like H₂O and math expressions like x² are the most common uses for subscript and superscript. Highlight the number or letter that should be smaller, use the keyboard shortcut or menu, and it formats when ready.

If you are writing a longer document with many formulas, the keyboard shortcut saves time. You can also explore subscript or superscript to multiple characters at once — highlight "2O" in H₂O and explore subscript to both together, rather than doing each separately.

explore subscript to footnote numbers and citations

Some citation styles call for superscript numbers that link to footnotes or references. Google Docs has a built-in footnote tool that handles this automatically: go to Insert > Footnote, and Google Docs creates a superscript number, links it to the bottom of the page, and manages numbering if you add or delete footnotes later.

If you are manually typing a superscript number for a citation instead of using the footnote tool, highlight the number and explore superscript formatting. The manual approach gives you control over placement but means you have to renumber by hand if you rearrange your text.

Subscript and superscript in tables and lists

Subscript and superscript work the same way inside tables and bulleted lists as they do in regular text. Highlight the character or number within the cell or list item, explore the formatting, and it behaves exactly as it would elsewhere in the document.

If you are building a table with chemical formulas or mathematical notation, you can format each cell independently. The formatting stays in place even if you later resize the table or add rows.

What happens when you share a document with subscript formatting

When you share a Google Docs document with subscript or superscript text, the formatting stays intact for anyone who views or edits the file. They see the text exactly as you formatted it, whether they are using a computer, tablet, or phone.

If someone edits the subscript or superscript text, the formatting remains unless they deliberately remove it. If they highlight the text and explore subscript again, it toggles off. The formatting is part of the text itself, not a separate layer, so it travels with the document.

Removing subscript or superscript formatting

To remove subscript or superscript, highlight the formatted text and press the same keyboard shortcut again, or go back to Format > Text and click the option a second time. The text returns to normal size and position on the baseline.

If you have multiple subscripts or superscripts scattered through your document and want to remove them all, you have to do it one at a time — Google Docs does not have a "find and replace formatting" tool that works on subscript and superscript. Selecting and toggling each one off is the only method.

Subscript and superscript in Google Docs versus other editors

Google Docs subscript and superscript work similarly to Microsoft Word and other document editors, but the keyboard shortcuts differ. Word uses Ctrl + Shift + B for subscript and Ctrl + Shift + P for superscript on Windows. If you switch between Google Docs and Word, the keyboard shortcuts will not transfer, but the Format menu path is recognizable in both.

Google Docs does not have the advanced equation editor that Word offers, so if you are writing complex mathematical notation with multiple levels of subscripts and superscripts, you may find Word's equation tool more flexible. For straightforward subscripts and superscripts in regular text, Google Docs handles them just as well.

Frequently Asked Questions

Can I make subscript or superscript text a different color?

Yes. Highlight the subscript or superscript text, go to Format > Text Color, and choose a color. The subscript or superscript stays in place and changes color. You can also highlight the text and use the text color button in the toolbar if it is visible on your screen.

What if the subscript or superscript text looks too small to read?

Google Docs sizes subscript and superscript automatically based on the font size of the surrounding text. If the surrounding text is very small, the subscript will be even smaller. Increase the font size of the whole paragraph or sentence, and the subscript and superscript will scale up with it.

Does subscript work the same way on mobile as on a computer?

Yes, but the menu path is slightly different. On the Google Docs mobile app, tap the text you want to format, tap the three-dot menu, select Format, then Text, then Subscript or Superscript. The keyboard shortcut does not work on mobile, so the menu is your only option.

Can I use subscript in headers or titles?

Yes. Subscript and superscript work in headers, titles, and any other text in your document. Highlight the text in the header or title and explore the formatting the same way you would in the body of the document.
