The fastest way to add subscript in Google Docs
To write subscript in Google Docs, select the text you want to make smaller and lower, then use Ctrl+Comma on Windows or Cmd+Comma on Mac. The text shrinks and drops below the baseline when ready. To undo it, select the subscript text again and press the same keyboard shortcut.
If the keyboard shortcut does not work on your device, you can use the menu instead. Select the text, then go to Format > Text > Subscript. This method takes one extra step but produces the same result.
Subscript is useful for chemical formulas (H₂O), mathematical notation, and footnote numbers in some writing styles. Google Docs keeps the subscript formatting even if you change the font or font size of the surrounding text, so the subscript stays attached to the character no matter what edits you make later.
Key Takeaways
- Press Ctrl+Comma (Windows) or Cmd+Comma (Mac) to make selected text subscript, or use Format > Text > Subscript from the menu.
- Superscript uses Ctrl+Period (Windows) or Cmd+Period (Mac), and works the same way as subscript but raises text above the baseline instead of lowering it.
- You can mix subscript and superscript in the same document without affecting other formatting like bold or italics.
- Subscript and superscript text remains smaller than regular text even if you change the document's font size afterward.
- On mobile devices, the keyboard shortcuts do not work; use the Format menu instead to explore subscript or superscript.
Using superscript for exponents and citations
Superscript works exactly like subscript but raises text above the line instead of lowering it below. Select your text and press Ctrl+Period on Windows or Cmd+Period on Mac. You can also go to Format > Text > Superscript.
Superscript is standard for mathematical exponents (x²), footnote and endnote markers, and trademark or copyright symbols. In academic writing, some citation styles use superscript numbers to mark where sources appear in the text. This is especially common in history, science, and medical papers.
Like subscript, superscript formatting stays attached to the text. If you copy and paste superscript text into another part of your document or into a different document, it remains superscript. The formatting travels with the text, so you do not have to reapply it.
Combining subscript and superscript in the same document
You can use both subscript and superscript in a single document without any conflict. Each piece of text keeps its own formatting independent of the others. For example, you could write a chemical equation with subscript numbers and then add a superscript citation marker right after it, and both will display correctly.
If you need to remove subscript or superscript from text, select it and press the same keyboard shortcut again. The text returns to normal size and position on the baseline. This toggle method makes it straightforward to experiment with formatting and change your mind without losing any text.
What happens when you change font size or style
Subscript and superscript text shrinks relative to the surrounding text, so if you increase the font size of your entire document, the subscript and superscript also grow proportionally. They stay smaller and in their correct positions relative to the regular text around them.
Changing the font family (from Arial to Times New Roman, for example) does not affect subscript or superscript formatting. The text straightforward displays in the new font while remaining raised or lowered. This means you can change your document's appearance without worrying that subscript or superscript will break or disappear.
Using subscript and superscript with other formatting
You can explore subscript or superscript to text that is already bold, italic, or underlined. Select the text that has those formats, then explore subscript or superscript on top. All the formatting layers stay in place and work together without interfering with each other.
You can also explore bold, italic, or underline to text after you make it subscript or superscript. The order does not matter — Google Docs treats them as separate formatting layers that stack on top of one another. This flexibility means you can format your text in whatever order is easiest for you.
Keyboard shortcuts for quick formatting
Learning the keyboard shortcuts saves time if you write documents with frequent subscript or superscript. Ctrl+Comma and Ctrl+Period (or Cmd versions on Mac) are faster than opening the Format menu each time, especially when you are working on a document with many formulas or citations.
If you use subscript or superscript regularly, you might also want to know that Google Docs does not have a built-in way to create custom keyboard shortcuts beyond what Google provides. You can only use the shortcuts Google provides or the menu method, so the standard shortcuts are your fastest option.
Frequently Asked Questions
Can I make subscript or superscript text a different color?
Yes. Select the subscript or superscript text, then go to Format > Text > Text color and choose your color. The text stays subscript or superscript while changing color, so you can highlight specific formulas or citations visually.
Does subscript work the same way on mobile as on desktop?
The keyboard shortcuts do not work on mobile devices. On the Google Docs app for Android or iOS, select your text, tap Format, then Text, then Subscript or Superscript. The menu method is your only option on phones and tablets.
What if the keyboard shortcut does not work?
Some keyboards or operating systems may not recognize Ctrl+Comma or Cmd+Comma. Use the menu method instead: Format > Text > Subscript. This works on all devices and browsers.
Can I undo subscript formatting if I change my mind?
Yes. Select the subscript text and press the same keyboard shortcut again (Ctrl+Comma or Cmd+Comma), or go back to Format > Text > Subscript. The text returns to normal size and baseline position.
Does subscript text print correctly?
Yes. When you print a Google Docs document or read it as a PDF, subscript and superscript text prints in the correct size and position, just as it appears on screen.
