The quickest way to add a footnote in PowerPoint

PowerPoint does not have a built-in footnote feature the way Word does. Instead, you add notes by inserting a text box at the bottom of your slide, typing your note there, and making it smaller or lighter so it does not compete with your main content. This takes about 30 seconds per slide.

If you need something more formal — where notes appear automatically at the end of your presentation or link to specific text — you are working around PowerPoint's limitations rather than using its design. Most people who need that structure switch to Keynote (on Mac) or Google Slides, both of which handle notes more smoothly.

Key Takeaways

  • PowerPoint has no automatic footnote system, so you manually add a text box at the bottom of each slide where you want a note.
  • Format your note text smaller (8 to 10 point) and in a lighter color so readers know it is supplementary information, not the main message.
  • If you need notes to link to specific words or appear in a separate section, Google Slides or Keynote handle this more naturally than PowerPoint does.
  • The Notes pane (View menu, then Notes Page) lets you write speaker notes that do not appear on the slide itself — useful if you are presenting and need reminders.

Adding a text box footnote to your slide

Open the slide where you want the footnote. Go to the Insert menu and select Text Box. Click and drag to create a small box at the bottom of your slide, below your main content. Type your note text directly into the box.

Once the text is in place, select all of it (Ctrl+A on Windows, Command+A on Mac) and reduce the font size to 8 or 10 point — small enough that it reads as secondary information. You can also change the text color to gray or a lighter shade to signal that this is not the main message. Right-click the text box border and select Format Shape to add a thin border or adjust transparency if you want the note to blend into the background.

Repeat this process for each slide that needs a footnote. The text box stays where you place it, so if you move or resize your main content later, you may need to adjust the footnote position to keep it clear.

Using the Notes pane for speaker notes instead

If your footnotes are really reminders for yourself while presenting — not information your audience needs to see — use the Notes Page instead. Go to the View menu and select Notes Page. You will see your slide at the top and a large text area below where you can type as much as you want. These notes appear only on your screen during presentation mode, not on the projected slide.

This is cleaner than cluttering your slides with small text. Your audience sees only the content you designed, and you have space to write full sentences, reminders, or talking points. When you present, switch to Presenter View (available in PowerPoint on Windows and Mac) to see your notes while the audience sees only the slide.

Linking a footnote to specific text

PowerPoint does not automatically link a footnote to a word the way Word does. If you want a superscript number next to a word that connects to a note, you have to create it manually. Type your text normally, then select the word you want to mark. Go to Insert and choose Text Effects, then Superscript to raise a small number above the line.

Type the matching number in your footnote text box at the bottom. This creates the visual connection, but there is no automatic link — a reader has to scan down to find the matching number. For a presentation with many footnotes, this becomes tedious and distracting. If you need this kind of structure regularly, consider whether Google Slides or Keynote would serve you better.

When to use Google Slides or Keynote instead

Google Slides does not have automatic footnotes either, but it handles text boxes more fluidly and lets you organize notes in a separate document linked to your presentation. Keynote (Apple's presentation software) has a Notes feature built into the slide master, so you can add notes that format consistently across all slides without manually resizing text boxes each time.

If your presentation is heavy on citations, sources, or detailed explanations that do not belong on the slide itself, these tools reduce friction. You spend less time formatting and more time on content. PowerPoint is stronger when your slides are visual and your notes are minimal — a few clarifications, not a second layer of information.

Formatting your footnote so it does not distract

The goal of a footnote is to be there if someone needs it, but not to pull attention away from your main message. Use a sans-serif font (like Calibri or Arial) in 8 or 9 point — readable but clearly smaller than your body text. Place it in the bottom margin, not floating in the middle of the slide. Leave at least a quarter-inch of white space between your main content and the footnote so they feel like separate layers.

If your slide background is dark, use a light gray or white text for the footnote. If the background is light, use dark gray or black. Avoid using the same color as your main text — the size difference alone should signal that this is secondary. A thin horizontal line above the footnote (a shape you can insert) also helps separate it visually, similar to how footnotes appear in printed documents.

Frequently Asked Questions

Can I make a footnote appear on multiple slides automatically?

No. Each slide is independent in PowerPoint, so you have to add the text box and format it on every slide where you want it. If you have the same footnote on many slides, copy the text box from one slide, paste it on the next, and edit the text. This is faster than creating each one from scratch.

Will my footnotes print if I print the presentation as handouts?

Yes, any text box on your slide will print. If you want footnotes to appear only on screen and not in printed handouts, put them in the Notes pane instead. Notes do not print unless you specifically choose to print the Notes Page view.

What if I need to cite a source on my slide?

Add the citation as a small text box at the bottom, formatted in 8 to 10 point gray text. Include the author, year, and source title. If the citation is long, consider moving it to the Notes pane and just putting a superscript number on the slide, then matching it to the full citation in your notes.

Can I use hyperlinks in a footnote?

Yes. Select the text in your footnote text box, go to Insert, then Hyperlink, and paste the URL. The link will work in presentation mode, so viewers can click it if they want more information. Test it before presenting to make sure it opens the right page.
