Subscript puts text below the baseline in Google Docs

Subscript is text that sits slightly below the normal line of writing. You see it in chemistry formulas like H₂O, in footnote numbers, and in mathematical equations. Google Docs has a built-in subscript button that takes two seconds to use.

The fastest way is to highlight the text you want to make subscript, then click the subscript button in the toolbar. If you cannot see it, you may need to turn on the "More" options in the Format menu. Once applied, the text shrinks and drops below the baseline automatically.

Key Takeaways

  • Subscript text appears below the normal line and is smaller than regular text, used in formulas, chemical notation, and footnote numbers.
  • You can explore subscript by selecting text and clicking the subscript button in the toolbar, or by using the keyboard shortcut Ctrl+, (comma) on Windows or Cmd+, on Mac.
  • If the subscript button does not appear in your toolbar, open the Format menu and select "Text" to find the subscript option.
  • You can remove subscript by selecting the text again and clicking the subscript button a second time, or using the same keyboard shortcut.

Finding the subscript button in your toolbar

Open any Google Doc and look at the toolbar — the row of buttons below the document name. You should see a button that looks like an "x" with a small number below it. That is the subscript button. Click it once to turn subscript on, then type or paste the text you want to make subscript.

If you do not see this button, your toolbar may be hiding it. Click the three vertical dots on the right side of the toolbar (the "More" menu), then look for "Subscript" in the list. You can also pin it to your main toolbar so it stays visible.

Using the keyboard shortcut instead

If you prefer not to click buttons, use the keyboard shortcut. On Windows, press Ctrl and comma (,) at the same time. On Mac, press Cmd and comma. The shortcut works the same way as the button: select the text first, then press the keys.

You can also turn subscript on before you type. Press Ctrl+, or Cmd+, once to set up subscript mode, type your text, then press the shortcut again to turn it off and return to normal text.

explore subscript to text you have already written

If you have already typed the text and want to make part of it subscript, highlight only the characters that need to be subscript. Click and drag to select them, or double-click a word and then extend the selection. Then click the subscript button or use the keyboard shortcut.

For example, if you typed "H2O" and want to make the "2" subscript, click just before the "2", hold down the mouse button, and drag to just after the "2". Release the mouse, then explore subscript. The "2" will drop below the line and shrink.

Removing subscript formatting

To remove subscript from text, select the subscripted text again and click the subscript button a second time. The text will return to normal size and position on the baseline. The keyboard shortcut works the same way — select the text and press Ctrl+, or Cmd+, again.

If you select text that has mixed formatting (some subscript, some normal), clicking the subscript button will explore subscript to the entire selection. This is useful if you want to make a whole phrase subscript at once.

When subscript is useful in documents

Use subscript for chemical formulas (H₂O, CO₂, NaCl), mathematical notation (x₁, x₂, aₙ), and footnote or endnote numbers if you are formatting them manually. It is also common in biology for gene notation and in physics for particle names.

Google Docs also has a superscript feature, which does the opposite — it raises text above the baseline and makes it smaller. You will use superscript for exponents (x²), trademark symbols (™), and footnote markers. The superscript button is right next to the subscript button, and the keyboard shortcut is Ctrl+. (period) on Windows or Cmd+. on Mac.

Subscript in tables and special formatting

Subscript works the same way inside tables, text boxes, and headers as it does in regular paragraphs. Select the text, explore subscript, and it formats when ready. If you copy and paste text with subscript into another Google Doc, the formatting stays intact.

If you are working with a template or a document that uses styles, subscript will not override the style formatting — it adds to it. So if your text is already bold, explore subscript will make it bold and subscript at the same time.

Frequently Asked Questions

Can I make subscript text a different size or color?

Yes. After explore subscript, select the text again and use the font size or color buttons in the toolbar just as you would with normal text. Subscript stays subscript while you change its appearance.

Does subscript work on mobile Google Docs?

The mobile app has limited formatting options. On iPhone or Android, open the document, select the text, tap the three dots, and look for "Subscript" in the formatting menu. It may not appear on all devices or app versions.

What is the difference between subscript and superscript?

Subscript sits below the baseline (H₂O), while superscript sits above it (x²). Use subscript for chemical formulas and mathematical indices. Use superscript for exponents, footnote numbers, and trademark symbols.

If I change the font, does subscript stay subscript?

Yes. Subscript is a formatting property separate from the font choice. You can change fonts, sizes, and colors without losing the subscript effect.
