How do you add subscript or superscript in Google Docs?

Two ways: Use Format → Text → Subscript/Superscript (Ctrl + , / Ctrl + . on Windows), or paste Unicode CO₂ and x² from our generator.

Built-in formatting stays in the Doc until export. Unicode is plain text, it survives copy into Gmail, Slides, or WhatsApp.

Method 1: Format Menu (Best for Beginners)

  1. Open your document in Google Docs.
  2. Select the text you want to change (for example the number 2 in H2O).
  3. Click Format in the top menu.
  4. Choose Text, then Subscript or Superscript.

This changes only the selected characters. It works well for short formulas in one document.

Method 2: Keyboard Shortcuts

SuperscriptCtrl + . (period)⌘ + . (period)

Select the text first, then use the shortcut. These are the fastest way for subscript in Google Docs when you edit often.

Method 3: Paste Unicode (CO₂, H₂O, x²)

Sometimes you want characters that stay subscript or superscript when you copy to email, chat, or another app. Use our subscript and superscript generator:

  1. Type plain text like CO2 or x2 on the generator.
  2. Pick Subscript or Superscript; for chemistry use Formula mode and Numbers Only: On.
  3. Click Copy, then paste into Google Docs.

This matches how many people search for how to write CO₂ in Google Docs, you can paste the finished symbols directly.
