The simplest way to add a footnote in PowerPoint

PowerPoint does not have a built-in footnote feature the way Word does. Instead, you add a footnote by creating a text box at the bottom of your slide, typing a small superscript number in your main text, and then typing the matching number and your note in that text box. This takes about 30 seconds per slide and works reliably across all versions of PowerPoint.

The reason PowerPoint lacks automatic footnotes is that slides are meant to be visual and minimal — footnotes belong in handouts or speaker notes, not on the slide itself. But if you need one on the slide, the manual approach is faster than hunting through menus.

Key Takeaways

  • PowerPoint has no automatic footnote function, so you create one by adding a superscript number in your text and a matching note in a text box at the slide bottom.
  • You can format the footnote text smaller and in a different color to distinguish it from your main content.
  • If you are presenting from notes rather than the slide itself, use the Notes pane instead of cluttering your slide with small text.
  • Speaker notes are invisible to your audience and are the better place for citations and detailed explanations.

Adding a superscript number to your text

Click on the text box that contains the word or phrase you want to footnote. Position your cursor right after that word — before any punctuation. Then type the number you want to use (usually 1, 2, 3, and so on in order).

With that number still selected, go to the Home tab at the top. In the Font group, click the superscript button — it looks like a small raised "x²". The number will shrink and move up. If you cannot find the button, right-click the number, choose Font, check the Superscript box, and click OK.

Creating the footnote text box at the bottom

Click in an empty area of the slide below your main text. Go to the Insert tab and click Text Box. Draw a rectangle across the bottom of the slide where you want your footnotes to sit. Type the same superscript number, then a space, then your note.

To make that superscript number in the footnote text box, use the same method: select the number, go to Home, and click the superscript button. Keep the note brief — one or two lines at most. If your note is longer, you are probably trying to fit too much into a slide.

Formatting your footnote to look intentional

Select all the text in your footnote text box. Reduce the font size to 10 or 12 points — smaller than your main text but still readable from the back of a room. You can also change the color to gray or a muted shade to signal that it is secondary information.

Do not make it so small that people squint. The point of a footnote is to provide information, not to hide it. If the text has to be unreadable to fit, move it to your speaker notes instead.

Using speaker notes for citations and explanations

If your footnote is a citation, a source, or a detailed explanation that the audience does not need to see, put it in your speaker notes instead. Click the Notes button at the bottom of the screen (or go to View and choose Notes Page). Type your note there. During your presentation, you will see the note on your screen but your audience will not.

This is the better choice for most situations. Your slides stay clean and focused, and you have all the detail you need when you are speaking. Footnotes on the slide itself should be rare — reserved for things the audience genuinely needs to read while looking at the slide.

Repeating the process for multiple footnotes

If you have two or three footnotes on one slide, use the same superscript numbers (1, 2, 3) in your main text, then list all three notes in the text box at the bottom. Separate each note with a line break or a small horizontal line if you want them visually distinct.

If you find yourself adding more than three footnotes to a single slide, stop and reconsider the slide. You are probably trying to say too much. Break it into two slides, or move the extra information to your speaker notes.

Copying footnotes across similar slides

If you have multiple slides with the same footnote — for example, a copyright notice or a data source that applies to several charts — create the footnote text box once, then copy it. Right-click the text box, choose Copy, then go to the next slide and paste it. Adjust the position if needed. This is faster than recreating it each time.

Make sure the superscript numbers still match between your main text and the footnote. If you copy a slide and then edit the main text, update the footnote numbers to stay in sync.

Frequently Asked Questions

Can I use automatic footnotes like in Word?

No. PowerPoint does not have Word's automatic footnote feature. You must manually create superscript numbers and text boxes. This is by design — slides are meant to be visual, not text-heavy.

Should footnotes appear on the slide or in speaker notes?

Speaker notes are the better choice for most footnotes. Put a note on the slide only if your audience needs to read it while looking at the slide. For citations, sources, and explanations, use speaker notes instead.

What if my footnote is too long to fit at the bottom?

Move it to speaker notes. If the text has to be tiny or wrap awkwardly to fit on the slide, it does not belong there. Your audience should never struggle to read a footnote.

Can I use letters instead of numbers for footnotes?

Yes. Use superscript letters (a, b, c) the same way you use numbers. Just be consistent — if you start with letters, use letters throughout the slide.

How do I make sure footnote numbers match between slides?

Number each slide's footnotes separately, starting with 1 on each slide. This is clearer than trying to number continuously across multiple slides. Your audience will not notice or care that slide 2 also has a footnote 1.
