Add Slide Numbers in PowerPoint: A Step-by-Step Guide

To add slide numbers in PowerPoint for Microsoft 365 on Windows, go to Insert > Header & Footer, check Slide number on the Slide tab, then choose Apply to All. PowerPoint adds an automatic number placeholder to your slides, so the numbers update with the slide order. You can also hide the number on the title slide, change where it appears, or adjust the starting number.

Slide numbers help people follow a presentation, refer back to a particular slide, and see how far along they are. Before you start, open the presentation you want to number. If its theme has a customized layout, allow a moment to check the placement and contrast after applying the numbers.

What You’ll Need

A PowerPoint presentation open in the desktop app. The steps below use PowerPoint for Microsoft 365 on Windows.
Permission to edit the presentation. If the file is read-only or protected, you may need to save an editable copy first.
For a polished result, a little time to check the title slide, slide layouts, and number visibility.

Step-by-Step

Open the Header and Footer controls. Select the Insert tab on the ribbon. In the Text group, choose Header & Footer. Depending on the ribbon width, the command may appear as Slide Number instead. You can also look for it under the Insert tab’s text-related commands. This opens the Header and Footer dialog, where slide numbering is controlled separately from notes and handouts.
Choose the Slide tab. In the dialog, select the Slide tab if it is not already active. The checkboxes on this tab control items shown on slides. The separate Notes and Handouts tab controls printed notes or handout pages; changing settings there does not add numbers to the slides in the presentation itself.
Turn on slide numbering. Check Slide number. The dialog shows the setting, but it may not display a sample number in the preview. PowerPoint uses a slide-number placeholder, which displays the appropriate number for each slide rather than fixed text you have to update manually.
Decide whether to number the title slide. If you want the opening slide to remain unnumbered, check Don’t show on title slide. This hides the number on the presentation’s title slide; it does not remove that slide from the sequence. For example, if the title slide is hidden from numbering, the next slide will normally display 2. Leave the option unchecked if every slide, including the title slide, should show its number.
Apply the setting to the presentation. Choose Apply to All to add numbers throughout the deck. Choose Apply if you only want to change the currently selected slide. For a normal presentation-wide setup, Apply to All is the practical choice. Close the dialog, then look at several slides, including the title slide and any slides with unusual layouts.
Check the result in Slide Show view. Start the show with F5 on Windows, or start from the current slide with Shift+F5. Confirm that the number is easy to see and does not overlap text, images, or other footer elements. Press Esc to return to editing. Numbers can look fine in the editor but be hard to read over a dark photo or colored background.
Adjust the number’s position or appearance if needed. In the normal editing view, go to View > Slide Master. Select the master or the specific layout used by the slide, then locate its slide-number placeholder. Drag or format that placeholder to change its position, font, size, or color. When finished, choose Close Master View. Changing the placeholder on a layout affects slides that use that layout; changing it on the top-level master can affect multiple layouts.
Set a different starting number if required. To make the first slide display a number other than 1, go to Design > Slide Size > Custom Slide Size. In the dialog, change Number slides from to the starting value you want, then confirm. Review the sequence afterward, especially if the title slide is hidden. This setting changes the displayed sequence; it does not add or delete slides.

On Mac: In PowerPoint for Microsoft 365, open Insert > Slide Number or Insert > Header & Footer, depending on the ribbon layout and app version. Use the Slide tab, select Slide number, choose whether to omit the title slide, and select Apply to All. The dialog labels and placement can vary slightly between Mac releases. The Slide Master controls are available from View > Slide Master. On PowerPoint for the web, look for the slide-number command on the Insert tab; if the control is unavailable in your version, open the deck in the desktop app to use the full Header and Footer options.

Common Mistakes

Choosing Apply instead of Apply to All. Apply changes the current slide, which can make it seem as if numbering did not work across the deck. Reopen the dialog and choose Apply to All when you want numbers on every applicable slide.
Checking the wrong tab. Numbering notes or handouts is different from numbering presentation slides. Make sure you are on the Slide tab before selecting Slide number.
Expecting the title slide to disappear from the count. Don’t show on title slide hides its number but does not renumber later slides. The next slide may still be labeled 2. If you want that slide to show 1, change the starting number or use a different numbering approach.
Typing numbers into text boxes. Manually entered numbers will not update when slides are moved, added, or deleted. Use the built-in Slide number setting so the displayed value follows the deck’s sequence.
Editing the wrong layout. A presentation can use several layouts, each with its own placeholders. If you move or format a number on one layout, slides based on another layout may not change.
Ignoring contrast and overlap. A number can blend into a background image or collide with a footer, chart, or caption. Check slides with different designs, not just the first slide that shows a number.

Tips

Keep placement consistent. A number in the same corner and at the same size on each layout looks intentional and is easier to find. Leave a margin from the slide edge so the number is not clipped when projected or printed.
Use a readable style. Choose a font size that remains legible from the back of a room. Use a color that contrasts with the slide background; on image-heavy slides, a subtle solid shape behind the number can help, if it fits the design.
Use the master for deck-wide formatting. Adjusting the number placeholder in Slide Master is usually more reliable than formatting numbers one slide at a time. Check layouts that intentionally use a different footer or background, since they may need separate adjustments.
Review sectioned presentations. PowerPoint numbers slides in sequence across the deck; it does not automatically restart numbering at each section. If a handout needs section-specific numbering, plan that separately and verify that manual labels will remain correct if the deck changes.
Check exported and printed copies. Slide numbers usually appear when you present or export slides, but print settings and layout can affect how content appears on paper. Preview the PDF or print layout before distributing it.

Troubleshooting

No numbers appear after you choose Apply to All. Reopen Insert > Header & Footer and check that Slide number is selected on the Slide tab. Confirm you chose Apply to All rather than Apply. Then inspect the slide in Slide Show view. If the setting is enabled but the number is still missing, the slide layout may not contain a visible slide-number placeholder.

To check the layout, open View > Slide Master and select the layout used by the affected slide. On the Slide Master tab, open Master Layout and check that Slide number is enabled. If the layout still lacks a placeholder, add or restore a slide-number placeholder using the Slide Master tools, then close Master View and check the slide again. A custom theme may have removed or hidden the placeholder, so you may need to repeat the check for more than one layout.

Only some slides show numbers. Those slides may use different layouts, or the number placeholder may have been removed or covered on particular layouts. In Slide Master view, inspect the layouts assigned to both a working slide and a missing slide. Also check whether a shape, image, or footer background is covering the number. If you have edited the master recently, verify that the affected slides still use the intended layout.

The number is in the wrong place or hard to read. Move and format the placeholder in Slide Master view rather than adding separate text boxes. If only one slide is affected, inspect its layout and any slide-level objects covering the placeholder. For a dark or busy background, choose a contrasting font color or adjust the layout so the number sits on a clear area.

The title slide has a number, or the sequence looks off. In the Header and Footer dialog, check Don’t show on title slide if you want to hide its number. Remember that hiding the title slide’s number does not change the subsequent slide numbers. To change the first displayed value, use Design > Slide Size > Custom Slide Size and edit Number slides from, then review the entire sequence.

Numbers differ after moving slides. Built-in slide numbers follow the slide’s current position in the deck, so a change in order can change displayed values. If a slide shows a fixed number that does not change, it may be typed text rather than a placeholder. Remove the manual text and enable the built-in number for that layout.

Frequently Asked Questions

Can I add numbers to only one slide?
Yes. Select that slide, open Insert > Header & Footer, check Slide number, and choose Apply rather than Apply to All. The slide’s layout must have a usable number placeholder.

Can I hide the number on the first slide but keep numbering the rest?
Yes. Select Don’t show on title slide in the Slide tab of the Header and Footer dialog, then choose Apply to All. The title slide remains part of the count, so the following slide generally displays 2.

Can I make the second slide display 1?
Yes. If the title slide is unnumbered, go to Design > Slide Size > Custom Slide Size and set Number slides from to 0. The next slide should then display 1. Check the full sequence, since the title slide itself is still slide 0 internally for this numbering setup.

Can I change the font, color, or position of slide numbers?
Yes. Open View > Slide Master, select the relevant master or layout, and edit the slide-number placeholder. Formatting can differ by layout, so review slides that use more than one layout before you finish.

Will the numbers update if I reorder slides?
Yes, when you use PowerPoint’s built-in slide-number placeholder. It displays the slide’s position in the deck, so moving, inserting, or deleting slides updates the sequence. Manually typed numbers do not update automatically.

Are slide numbers the same as page numbers in notes and handouts?
No. Slide numbers appear on presentation slides. Printed notes and handouts have separate header and footer settings, available on the Notes and Handouts tab of the Header and Footer dialog.
