After creating the subscript, select the subscripted text. Then, click on the font size dropdown in the toolbar. You can choose from the available sizes or enter a custom size.

Changing the Font Family

You can also change the font family of the subscript. After selecting the subscripted text, click on the font family dropdown in the toolbar. Choose from the available fonts or search for a specific font.

Changing the font family can help you create unique effects, like using a different font for subscripts in a mathematical equation or a chemical formula.

Now that you know how to make a letter subscript in Google Docs, you can enhance your documents with this useful formatting tool. Happy subscripting!
