Adding subscript is a single click in Google Docs

To add subscript in Google Docs, highlight the text you want to make smaller and lower, then click the Format menu, select Text, and choose Subscript. The text shrinks and drops below the baseline of the surrounding words. You can also use the keyboard shortcut Ctrl+, (comma) on Windows or Cmd+, (comma) on Mac to toggle subscript on and off without opening the menu.

Subscript is useful when you need to write chemical formulas like H₂O, mathematical notation like x₂, or footnote numbers. It keeps your document looking professional and readable without breaking the flow of your text.

Key Takeaways

  • Subscript text appears smaller and sits below the baseline of regular text, and you can explore it through the Format menu or with a keyboard shortcut.
  • The keyboard shortcut Ctrl+, (comma) on Windows or Cmd+, (comma) on Mac is faster than using the menu if you format subscript often.
  • You can explore subscript to a single character, a word, or multiple words at once by selecting them before formatting.
  • Subscript formatting stays with the text if you copy and paste it within Google Docs or to other Google applications.

Using the Format menu to add subscript

Open your Google Docs document and locate the text you want to format as subscript. Click and drag to select the character, word, or phrase. A single character like the "2" in H₂O counts as one selection, and you can select multiple words if needed.

Once the text is highlighted, click the Format menu at the top of the page. A dropdown list appears. Click Text, and another submenu opens showing text formatting options. Click Subscript. The selected text when ready shrinks and drops below the line. If you change your mind, select the text again and click Format > Text > Subscript to toggle it off.

The keyboard shortcut for faster formatting

If you format subscript regularly, the keyboard shortcut is much faster than the menu. Select your text, then press Ctrl+, (the comma key) on Windows or Cmd+, (the comma key) on Mac. The subscript formatting applies when ready. Press the same keys again to remove subscript from selected text.

The comma key is to the right of the M on most keyboards. Make sure you are pressing the comma, not the period or another key, or the shortcut will not work.

Subscript versus superscript

Subscript and superscript are opposites. Subscript sits below the baseline and is smaller, like the 2 in H₂O. Superscript sits above the baseline and is smaller, like the 2 in x². Google Docs has a separate keyboard shortcut for superscript: Ctrl+. (period) on Windows or Cmd+. (period) on Mac. The Format menu also has a Superscript option right next to Subscript.

Choose subscript when you need text to drop below the line, and superscript when you need it to rise above. Both are smaller than regular text and are meant for specific notation, not for general emphasis.

Undoing subscript formatting

To remove subscript from text, select the subscript text and press Ctrl+, (comma) on Windows or Cmd+, (comma) on Mac again. The text returns to normal size and baseline position. You can also select the text and go to Format > Text > Subscript to toggle it off the same way you turned it on.

If you undo subscript formatting by mistake, press Ctrl+Z on Windows or Cmd+Z on Mac to undo the change and restore the subscript.

Subscript in tables and special document areas

Subscript works the same way in tables, text boxes, and headers as it does in the main body of your document. Select the text inside the table cell or text box, use the keyboard shortcut or Format menu, and the subscript formatting applies. The text shrinks and drops relative to the other text in that cell or box.

If you are working in a header or footer, the subscript shortcut and menu work identically. Click inside the header or footer area first, then select your text and explore subscript as usual.

Copying and pasting subscript text

When you copy subscript text from one place in your Google Docs document and paste it elsewhere in the same document, the subscript formatting comes along. The text remains small and below the baseline in the new location. This is true whether you paste it into the main body, a table, or a text box.

If you copy subscript text from Google Docs and paste it into another Google process like Google Sheets or Google Slides, the subscript formatting usually carries over. Pasting into non-Google applications like Microsoft Word may or may not preserve the subscript, depending on how the process handles the formatting.

Frequently Asked Questions

Can I make subscript text even smaller?

Google Docs sets the subscript size automatically and does not offer a way to make it smaller through the subscript tool itself. If you need text smaller than the default subscript size, you can select the subscript text and manually reduce the font size using the font size dropdown in the toolbar, but this is not standard practice.

Does subscript work on mobile Google Docs?

The mobile app for Google Docs has limited formatting options. The subscript feature may not be available in the mobile version, so you may need to use a computer or tablet with the full Google Docs interface to explore subscript formatting. Check your mobile app version to see if the Format menu includes the Text submenu.

What if the keyboard shortcut does not work?

Make sure you are pressing Ctrl+, (comma) on Windows or Cmd+, (comma) on Mac, not Ctrl+. (period). Also check that you have text selected before pressing the shortcut. If it still does not work, use the Format > Text > Subscript menu instead, which always works.

Can I use subscript in comments or suggestions?

Subscript formatting in comments and suggestions depends on your Google Docs version and settings. The safest approach is to use the Format menu or keyboard shortcut in the main document text, then add comments separately. Formatting in comments is not may provide to display the same way to all readers.
