Subscript puts text below the line and makes it smaller

Subscript is text that sits slightly below the normal line of writing and appears in a smaller font. In Google Docs, you can add subscript to any text you've already typed, or type new text in subscript format. The most direct way is to use the keyboard shortcut Ctrl+, (comma) on Windows or Cmd+, (comma) on Mac, which toggles subscript on and off.

Subscript is useful for chemical formulas (like H₂O), mathematical notation, footnote references, and scientific writing. Once you turn subscript on, everything you type will be subscripted until you turn it off again by pressing the same shortcut. The formatting stays with the text if you copy it to another document or download the file.

Key Takeaways

  • Use Ctrl+, (comma) on Windows or Cmd+, (comma) on Mac to toggle subscript on and off.
  • You can apply subscript to text you've already written by selecting it first, then using the keyboard shortcut.
  • The Format menu offers a Subscript option under Text if you prefer not to use the keyboard shortcut.
  • Subscript formatting stays with the text when you copy and paste it to other Google Docs or compatible programs.
  • Superscript (raised text) uses a different shortcut: Ctrl+. or Cmd+. with a period instead of a comma.

Using the keyboard shortcut to add subscript

The fastest way to add subscript is the keyboard shortcut. On Windows, press Ctrl and the comma key at the same time. On Mac, press Cmd and the comma key. When subscript is active, the text you type will automatically appear smaller and below the baseline.

To turn subscript off, press the same shortcut again. You'll see the cursor return to normal size and position. This on-off toggle means you can move between regular text and subscript without leaving the keyboard. The shortcut works whether you're typing new text or have selected existing text.

Applying subscript to text you've already typed

If you've already written the text you want to subscript, select it first by clicking and dragging across the words or characters. Then press Ctrl+, (Windows) or Cmd+, (Mac). The selected text will immediately shift to subscript format.

You can select and subscript individual characters, whole words, or multiple words at once. If you change your mind, select the subscripted text again and press the same shortcut to remove the formatting. This works for any text in your document, whether it's in the middle of a sentence or on its own line.

Using the Format menu instead of the keyboard shortcut

If the keyboard shortcut doesn't work on your device or you prefer menu navigation, open the Format menu at the top of the document. Click Text, then select Subscript from the dropdown. This applies subscript to any text you've selected, or turns on subscript mode if nothing is selected.

The Format menu route takes a few more clicks than the keyboard shortcut, but it works the same way on all devices and browsers. You can also use this method to turn subscript off by clicking Format > Text > Subscript again. This is especially useful on mobile devices or keyboards where the comma key is hard to reach.

Subscript and superscript are different formatting

Superscript is the opposite of subscript — it raises text above the line instead of lowering it below. In Google Docs, superscript uses the shortcut Ctrl+. (period) on Windows or Cmd+. (period) on Mac. Superscript is common for exponents (like x²), trademark symbols, and footnote markers.

Don't confuse the two shortcuts: comma for subscript, period for superscript. Both are toggles that work the same way — select text or turn the mode on, type or paste, then turn it off when you're done. You can use both in the same document without any conflict.

What happens to subscript when you copy or share the document

Subscript formatting is preserved when you copy text from Google Docs and paste it into another Google Doc. If you paste into Microsoft Word or most other word processors, the subscript usually stays intact. However, if you paste into a plain text editor or email, the subscript formatting will be lost and the text will appear at normal size and position.

When you share a Google Doc with others, they see the subscript exactly as you formatted it. If they download the document as a PDF or Word file, subscript remains in both formats. The formatting is part of the document itself, not dependent on how it's viewed or shared. This means your chemical formulas and mathematical notation will look the same no matter how the document is opened.

Frequently Asked Questions

Can I make subscript text a different color or font?

Yes. Select the subscripted text and use the text color or font tools in the toolbar, just as you would with regular text. Subscript is a size and position change, not a separate text style, so all other formatting options work normally on subscripted text.

Does subscript work in Google Docs on mobile?

The keyboard shortcut may not work on mobile devices, but you can use the Format menu. Tap Format, then Text, then Subscript. Some mobile keyboards don't have easy access to the comma key, so the menu route is often simpler on phones and tablets.

What if the keyboard shortcut isn't working?

Try the Format menu instead. If neither works, your keyboard layout or browser extension may be interfering. Restart Google Docs or try a different browser. The Format menu method is the most reliable fallback if shortcuts fail.

Can I undo subscript formatting?

Yes. Select the subscripted text and press the subscript shortcut again (Ctrl+, or Cmd+,), or go to Format > Text > Subscript. The text will return to normal size and position. You can also use Ctrl+Z (Cmd+Z on Mac) to undo the last action.

Will subscript work if I'm using Google Docs offline?

Yes. Subscript formatting works the same way in offline mode as it does online. The keyboard shortcut and Format menu both function normally. When you reconnect to the internet, your changes sync automatically.
