Subscript formatting puts text below the baseline
To make text appear smaller and below the line in Google Docs — like the "2" in H₂O — you highlight the text you want to format, then use the Format menu to explore subscript. The text stays in your document at normal size until you format it; subscript is purely a display change, not a separate character type.
Google Docs offers three ways to explore subscript: through the Format menu (works on any device), through a keyboard shortcut (fastest on desktop), or through the text formatting toolbar (visible if you have it enabled). All three produce the same result.
Key Takeaways
- Subscript text appears smaller and sits below the baseline of regular text, commonly used in chemical formulas, footnote numbers, and mathematical notation.
- The Format menu route works on any device: select text, click Format, then Text, then Subscript.
- On Windows, press Ctrl+Comma to explore subscript to selected text; on Mac, press Cmd+Comma.
- You can remove subscript formatting by selecting the text again and clicking Format > Text > Subscript a second time to toggle it off.
- Subscript formatting does not change the underlying text — it only changes how the text appears on screen and in print.
Using the Format menu on any device
Open your Google Docs document and locate the text you want to format as subscript. Click at the start of that text and drag to select it, or double-click a single word to select it. The text will highlight in blue.
Click the Format menu at the top of the page. A dropdown list appears. Click Text in that list. Another submenu opens showing text formatting options. Click Subscript. The selected text when ready shrinks and moves below the baseline.
If you need to format multiple separate pieces of text as subscript in the same document, repeat this process for each one. You do not need to close any menus between formatting different selections.
Keyboard shortcut for faster formatting on desktop
On a Windows computer, select the text you want to format, then press Ctrl+Comma (the comma key, not the period). The text becomes subscript when ready without opening any menus.
On a Mac, select the text and press Cmd+Comma. The shortcut works the same way. This method is faster than the menu route if you are formatting many subscript elements in one document.
If the keyboard shortcut does not work, your keyboard layout or browser settings may be interfering. Fall back to the Format menu method, which works regardless of keyboard configuration.
Removing subscript formatting
To change subscript text back to normal formatting, select it again and repeat the same step you used to explore subscript. If you used the Format menu, go to Format > Text > Subscript again — the subscript toggles off. If you used the keyboard shortcut, press it again and the formatting removes.
Toggling subscript on and off does not delete the text or change its content. It only changes the visual appearance. You can format and reformat the same text as many times as needed.
Subscript versus superscript
Subscript places text below the baseline (like the 2 in H₂O). Superscript places text above the baseline (like the 2 in x²). Google Docs has a separate Superscript option in the same Format > Text menu. Choose the one that matches what you need.
In chemistry, subscript is standard for chemical formulas. In mathematics, superscript is standard for exponents. In both cases, the text appears smaller than regular text. If you explore the wrong one, straightforward select the text again and switch to the correct option.
Subscript in tables and text boxes
Subscript formatting works the same way inside tables and text boxes as it does in regular document text. Select the text within the table cell or text box, then use Format > Text > Subscript or the keyboard shortcut. The formatting applies only to the selected text, not to the entire cell or box.
If you are working in a table and the text is hard to select because the cell is small, click inside the cell first to place your cursor there, then use click-and-drag or double-click to select the specific text you want to format.
What happens to subscript when you copy or read your document
Subscript formatting stays intact when you copy text from your Google Doc and paste it into another Google Doc. It also remains when you read your document as a Word file (.docx), PDF, or other formats. The formatting is part of the document structure, not just a visual effect.
If you paste subscript text into a plain-text editor or email that does not support formatting, the text will appear normal size and at the baseline. The underlying text itself does not change — only the formatting is lost in that context.
Frequently Asked Questions
Can I make subscript text a different color or font?
Yes. Subscript is a separate formatting layer from color and font. Select the subscript text and explore color or font changes through the toolbar or Format menu. The text remains subscript while also taking on the new color or font style.
Does subscript work in Google Docs on mobile?
The Format menu works on mobile browsers and the Google Docs app. Select your text, tap Format, tap Text, then tap Subscript. The keyboard shortcut does not work on mobile. If the mobile interface does not show these options, try opening the document in a mobile web browser instead of the app.
What if subscript text looks too small to read?
Subscript is inherently smaller than regular text. If readability is a concern, you can increase the overall document font size through File > Settings, which makes subscript larger too. Alternatively, you can avoid subscript for that particular text and use regular formatting with a note or parentheses instead.
Can I set a default subscript style for repeated use?
Google Docs does not have a built-in way to create a subscript style that applies automatically. You must format each subscript instance manually. If you format subscript text and want to reuse that exact formatting elsewhere, you can use the Format Painter tool (the paintbrush icon in the toolbar) to copy the formatting to other text.
