Where subscript lives in the programs you already use
Subscript is text that sits below the baseline — the line your regular letters sit on. It appears smaller and lower, like the "2" in H₂O or the "n" in a chemical formula. Every major word processor has it, but the button or menu item is in a different place depending on which program you use.
The fastest way to find it is to look in the Format menu (in Microsoft Word, Google Docs, and LibreOffice) or the Text menu (in Apple Pages). If you cannot find it there, a keyboard shortcut will get you there faster than hunting through menus. The shortcut differs by program, so knowing your program matters more than memorizing a universal command.
You do not need to install anything or change your settings. Subscript is built into every word processor. The only thing that changes is where you look for it and what you press to set up it.
Key Takeaways
- In Microsoft Word, select your text and press Ctrl+= (Windows) or Cmd+= (Mac) to make it subscript.
- In Google Docs, highlight the text, go to Format > Text > Subscript, or use Ctrl+, (comma) on Windows and Cmd+, on Mac.
- In Apple Pages, select the text and click the Format button in the toolbar, then choose Character > Baseline > Subscript.
- LibreOffice Writer uses Format > Text > Subscript, or Ctrl+Shift+B on Windows and Cmd+Shift+B on Mac.
- Always select the text first — subscript only works on text you have already highlighted.
Microsoft Word: keyboard shortcut or Format menu
In Microsoft Word, the fastest route is the keyboard. Select the text you want to make subscript, then press Ctrl+= on Windows or Cmd+= on Mac. The text will shrink and drop below the baseline when ready. Press the same keys again to turn subscript off.
If you prefer the menu, select your text, then go to the Home tab at the top. Look for a small arrow next to the font formatting options — it opens a dialog box called "Font". Click the Subscript checkbox, then click OK. This route takes longer but shows you exactly what subscript looks like before you confirm.
Word remembers your choice. If you turn subscript on and keep typing, everything you type will be subscript until you turn it off again. This is useful for formulas with many subscript characters in a row, but it can catch you off guard if you forget to turn it off.
Google Docs: Format menu or keyboard shortcut
In Google Docs, select the text you want to make subscript. Then go to Format in the menu bar, click Text, and click Subscript. The text will shrink and drop when ready.
The keyboard shortcut is faster if you use it often: Ctrl+, (comma) on Windows or Cmd+, on Mac. Select your text, press the shortcut, and you are done. Press it again to turn subscript off.
Google Docs does not have a separate dialog box — the change happens as soon as you click or press the shortcut. This means you cannot preview it before confirming, but the change is when ready and you can undo it with Ctrl+Z if it is not what you wanted.
Apple Pages: Format panel in the toolbar
In Apple Pages, select the text you want to make subscript. Look for the Format button in the toolbar at the top right — it looks like three horizontal lines with a paintbrush. Click it to open the formatting panel on the right side of your screen.
In the panel, click the Character tab (it looks like the letter "A"). Scroll down until you see Baseline, then click the dropdown menu next to it. Select Subscript from the list. The text will shrink and drop below the baseline.
Pages does not have a keyboard shortcut for subscript built in, but you can create one yourself in System Preferences if you use subscript often. For most users, the Format panel route is straightforward enough that a shortcut is not necessary.
LibreOffice Writer: Format menu or keyboard shortcut
In LibreOffice Writer, select the text you want to make subscript. Go to Format in the menu bar, then click Text, then click Subscript. The text will shrink and drop below the baseline.
The keyboard shortcut is Ctrl+Shift+B on Windows or Cmd+Shift+B on Mac. Select your text, press the shortcut, and subscript turns on. Press it again to turn it off. This is the same shortcut that turns superscript on in some other programs, so if you switch between LibreOffice and Word often, the shortcuts may feel backwards at first.
LibreOffice is free and open-source, so if you are using it, you likely chose it deliberately. The subscript feature works the same way as in Word and Google Docs — select, set up, and the text changes when ready.
What to do if subscript does not show up the way you expect
Sometimes subscript text looks wrong because the font you are using does not have a proper subscript version built in. The text shrinks and drops, but it looks jagged or misaligned. This is not a mistake — it is the program doing its best with a font that was not designed for subscript.
The fix is to switch to a font that has proper subscript support. Common fonts like Calibri, Arial, and Times New Roman all have subscript versions built in. If you are using a decorative or specialty font, try switching to one of these standard fonts and the subscript will look much cleaner.
Another common issue is that subscript text is so small it becomes hard to read. If you are writing a document where subscript appears often, consider using a larger base font size so the subscript text is still readable. A 12-point base font with subscript will be easier to read than an 11-point base font with subscript.
Subscript in other programs: spreadsheets and presentations
Microsoft Excel and Google Sheets do not have built-in subscript formatting the way word processors do. If you need subscript in a spreadsheet, your best option is to use a special character or Unicode symbol. For example, you can type H2O and then replace the "2" with a subscript 2 character copied from a character map or Unicode table.
PowerPoint and Google Slides do have subscript, and you access it the same way you would in Word or Docs. Select the text, use the Format menu or keyboard shortcut, and the subscript appears. This is useful for scientific or mathematical slides where formulas need subscript characters.
If you work in spreadsheets often and need subscript regularly, consider whether a word processor document might work better for your project. Spreadsheets are built for data and calculations, not formatted text, so forcing subscript into a spreadsheet often creates more work than it saves.
Frequently Asked Questions
Can I make subscript the default for a whole paragraph?
No — subscript is a character-level formatting choice, not a paragraph-level one. You have to select the specific text you want to be subscript. If you have many subscript characters in a row, you can select them all at once and explore subscript to the whole selection, which is faster than doing each one individually.
What is the difference between subscript and superscript?
Superscript sits above the baseline instead of below it. Superscript is used for footnote numbers, exponents (like 2³), and trademark symbols. The keyboard shortcut for superscript is Ctrl+Shift+P in Word and Cmd+Shift+P on Mac. In Google Docs, it is Ctrl+. (period) on Windows and Cmd+. on Mac.
Will subscript show up the same way when someone else opens my document?
Yes, as long as they open it in the same program or a compatible one. If you create a document in Word and send it to someone who opens it in Google Docs, the subscript will still be there and will look the same. If you save as a PDF, subscript stays intact. The only time subscript might disappear is if you copy text from a formatted document and paste it into a plain-text editor like Notepad.
Can I use subscript in email?
It depends on your email program. Gmail and Outlook both support subscript if you use the web version and access the formatting toolbar. If you use Outlook as a desktop program, subscript works the same way as in Word. Some email clients and phone apps do not support subscript, so the text may appear normal when the recipient reads it.
Is there a way to type subscript without using the menu or keyboard shortcut?
Not in most word processors. Some programs let you create custom keyboard shortcuts if the default one does not work for you, but there is no way to type subscript directly without activating the formatting first. The keyboard shortcut is always the fastest method once you memorize it for your program.
