Subscript and superscript let you place text smaller and lower or higher than the baseline of regular text

Subscript shrinks text and moves it below the line — useful for chemical formulas like H₂O or footnote markers. Superscript shrinks text and raises it above the line — used for exponents like x², trademark symbols, or footnote numbers. Both are formatting options built into PowerPoint, and you apply them the same way you would bold or italicize.

PowerPoint handles subscript and superscript through the Format menu or a keyboard shortcut. The text stays in the same text box; you are only changing how it displays. Once you format text this way, it stays formatted even if you move or copy the slide.

Key Takeaways

  • Select the text you want to format, then use Format > Text > Subscript or Superscript, or use the keyboard shortcut Ctrl+= for subscript and Ctrl+Shift+= for superscript on Windows.
  • On Mac, use Cmd+= for subscript and Cmd+Shift+= for superscript.
  • You can format a single character, a word, or multiple words — select exactly what you need before applying the format.
  • Subscript and superscript text is smaller by default, but you can select it afterward and change the font size if you need it larger or smaller.
  • The formatting saves with your file and displays the same way on any device or version of PowerPoint.

How to apply subscript in PowerPoint

Click inside the text box where your text is. Use your mouse or keyboard to select only the characters you want to make subscript — for example, the "2" in H₂O. Do not select the whole word or formula, just the part that should go below the line.

On Windows, hold Ctrl and press the equals sign (=). On Mac, hold Cmd and press the equals sign. The selected text shrinks and moves below the baseline immediately. If you need to undo it, select the text again and press the same shortcut a second time.

Alternatively, go to the Format menu at the top, select Text, then click Subscript. This method works the same way but takes more steps. Both the keyboard shortcut and the menu route produce identical results.

How to apply superscript in PowerPoint

Click in your text box and select only the characters that should appear above the line — for instance, the "2" in x². Again, be precise: select just what needs to move up, not surrounding text.

On Windows, hold Ctrl+Shift and press the equals sign (=). On Mac, hold Cmd+Shift and press the equals sign. The text shrinks and rises above the baseline right away. Press the same shortcut again to remove the formatting.

You can also use Format > Text > Superscript from the menu. Both methods produce the same result, so choose whichever feels faster to you.

Changing the size of subscript and superscript text

By default, PowerPoint makes subscript and superscript text smaller than the surrounding text — usually about 58% of the original size. This is standard and usually looks right, but you can adjust it if needed.

Select the subscript or superscript text you want to resize. Use the font size dropdown in the toolbar (or Format > Character > Font Size) to make it larger or smaller. You can also select it and use Ctrl+] to increase size or Ctrl+[ to decrease size in small increments. This gives you fine control over how prominent the subscript or superscript appears on your slide.

Removing subscript or superscript formatting

Select the formatted text and press the same keyboard shortcut you used to apply it. For subscript on Windows, that is Ctrl+=; for superscript, Ctrl+Shift+=. Pressing it twice toggles the formatting off.

You can also select the text, go to Format > Text, and click the subscript or superscript option again to turn it off. The text returns to normal size and baseline position immediately.

When subscript and superscript are useful in presentations

Subscript works well for chemical formulas (H₂SO₄), mathematical notation (aₙ), and sometimes for footnote or reference numbers in smaller text. Superscript is standard for exponents (2³), trademark symbols (™), copyright marks (©), and footnote references.

In a slide with a lot of formulas or technical content, these formats make the slide easier to read and more professional-looking. They also help distinguish between different parts of an equation or label without cluttering the slide with extra text boxes. Using them correctly signals that your presentation was built with attention to detail.

Frequently Asked Questions

Can I use subscript and superscript in slide titles?

Yes. Click in the title text box, select the characters you want to format, and apply subscript or superscript the same way you would in a regular text box. The formatting works anywhere text appears in PowerPoint.

Will subscript and superscript show up the same way if I share the file?

Yes. The formatting is saved in the file itself, so anyone who opens the presentation will see subscript and superscript exactly as you formatted it, whether they open it on Windows, Mac, or online.

What if the keyboard shortcut does not work?

Make sure you have selected the text first — the shortcut only works on highlighted characters. If it still does not work, use the Format menu instead: Format > Text > Subscript or Superscript. You can also check your keyboard settings if you have remapped the equals key.

Can I make subscript or superscript text a different color?

Yes. Select the subscript or superscript text and use the font color tool in the toolbar, or go to Format > Character > Font Color. The color change applies only to the selected text, so you can have colored subscript while the rest of the text stays black.

Does subscript and superscript work in PowerPoint Online?

Yes, but the keyboard shortcuts may differ. In PowerPoint Online, use the Format menu: go to Format > Text > Subscript or Superscript. The menu route is more reliable in the web version than keyboard shortcuts, which can conflict with browser commands.
