Insert subscript or superscript text

Superscript and subscript refer to numbers that are positioned slightly higher or slightly lower than the text on the line. For example, a footnote or endnote number reference is an example of superscript (footnote¹), and a scientific formula might use subscript text (H₂O).

Make text subscript or superscript

1. Select the text that you want to format as subscript or superscript.

2. Do one of the following:

   • On the Home tab, in the Font group, click Subscript. Or press CTRL+=.

     

   • On the Home tab, in the Font group, click Superscript. Or press CTRL+SHIFT+=.

     

   Note: Keyboard shortcuts do not work if you are using Word Online.

3. To undo the formatting, click the Subscript or Superscript button again, or repeat the keyboard shortcut.
