The Two Ways to Add Subscript

Subscript is text that sits below the baseline — like the "2" in H₂O or the "n" in aₙ. Google Docs gives you two ways to create it: through the Format menu, or by using a keyboard shortcut. The Format menu works on any device. The keyboard shortcut is faster if you use subscript often.

Both methods do the same thing: they shrink the text and move it down slightly. The text stays in your document as regular text — you are not inserting a symbol or special character. This means you can edit it, search for it, and copy it like any other word.

Key Takeaways

  • Select the text you want to make subscript, then open the Format menu and choose Text, then Subscript.
  • On Windows, press Ctrl and the comma key at the same time to turn selected text into subscript.
  • On Mac, press Cmd and the comma key to create subscript with a keyboard shortcut.
  • You can undo subscript by selecting the text again and clicking Format > Text > Subscript a second time, or by using the keyboard shortcut again.

Using the Format Menu on Any Device

Open your Google Docs document and find the text you want to make subscript. Click at the start of that text and drag to select it — the text will highlight in blue. Make sure you have selected only the characters you want to shrink and lower.

Click the Format menu at the top of the page. A dropdown list will appear. Move your mouse down to the word "Text" and hover over it — a second menu will open to the right. Click "Subscript" in that second menu. The selected text will when ready become subscript.

If you need to undo this, select the same text again, go back to Format > Text > Subscript, and click Subscript a second time. The text will return to normal size and position.

Using the Keyboard Shortcut on Windows

Select the text you want to make subscript by clicking and dragging. Hold down the Ctrl key and press the comma key (,) at the same time. You should hold both keys for a moment, then release them together. The text will become subscript when ready.

This shortcut works in Google Docs on Windows computers, including laptops. If the shortcut does not work, your keyboard layout may be different — in that case, use the Format menu instead.

Using the Keyboard Shortcut on Mac

Select the text you want to make subscript. Hold down the Cmd key (the key with the Apple logo) and press the comma key (,) at the same time. Hold both keys for a moment, then release them. The text will become subscript.

On Mac, this is the standard shortcut for subscript in Google Docs. If you use subscript regularly in your writing, this shortcut will save you time compared to opening the Format menu each time.

When Subscript Does Not Appear to Work

If you select text and explore subscript but nothing seems to happen, check that you actually selected the text. The selection should show as a blue highlight. If the text is not highlighted, click and drag again to select it, then try the Format menu or keyboard shortcut again.

Another reason subscript might not be visible is if your document is zoomed in or out very far. Try zooming to 100% by clicking the zoom percentage in the top right corner and selecting "100%". The subscript will be there — it may just be hard to see at unusual zoom levels.

Subscript in Tables and Text Boxes

Subscript works the same way inside tables and text boxes as it does in regular document text. Select the text, use Format > Text > Subscript or your keyboard shortcut, and the text will become subscript. This is useful if you are building a table with chemical formulas or mathematical notation.

If you are copying text with subscript from another document or website into Google Docs, the subscript formatting may not come along. Paste the text as plain text first, then select the characters that should be subscript and explore the formatting in Google Docs.

Subscript Versus Superscript

Superscript is the opposite of subscript — it sits above the baseline instead of below. In Google Docs, superscript uses the same menu path: Format > Text > Superscript. On Windows, the keyboard shortcut is Ctrl and the period key (.). On Mac, it is Cmd and the period key.

Use subscript for chemical formulas (H₂O), footnote numbers in some styles, and mathematical notation where a variable has a subscript index. Use superscript for exponents (x²), footnote markers, and trademark symbols (™).

Frequently Asked Questions

Can I make subscript text a different color or font?

Yes. Select the subscript text and use the text color or font tools in the toolbar, just as you would with any other text. The subscript formatting stays in place while you change the appearance.

Does subscript work when I read my document as a PDF or Word file?

Yes. When you read a Google Docs document as a PDF or as a Microsoft Word file (.docx), subscript formatting is preserved. The subscript text will appear correctly in the downloaded file.

What if my keyboard does not have a comma key in the same place?

International keyboards may have different key layouts. If the keyboard shortcut does not work, use the Format menu instead — Format > Text > Subscript works on any keyboard layout.

Can I search for text that is subscript?

Yes. Use Ctrl+F (or Cmd+F on Mac) to open the search box and type the text you are looking for. Google Docs will find subscript text the same way it finds regular text — the subscript formatting does not hide it from search.
