How to Put a PowerPoint Slideshow on Loop

To make a PowerPoint presentation repeat, open it in the desktop app and choose Slide Show > Set Up Slide Show, then select Loop continuously until ‘Esc’ and click OK. Start the show to check the result. If you want it to run unattended, also give each slide a transition time; looping repeats the show, but does not by itself make slides advance automatically.

What You’ll Need

A PowerPoint presentation saved as a .pptx file, preferably with a backup copy if you are making substantial changes.
The PowerPoint desktop app for Windows or Mac. The steps below use Microsoft 365 on Windows; PowerPoint for Mac has a similar setup dialog, with minor differences in ribbon layout.
For an unattended display, a duration for each slide and a computer that can stay awake while the presentation runs.

Step-by-Step

Open the presentation in PowerPoint. Use the desktop app rather than relying on a browser preview if you need full control over show settings. Save the file before changing it, and consider using File > Save As to make a separate copy for the looping version. This keeps the original presentation available if you later need a version that does not repeat.
Decide whether the slides should advance by themselves. A loop setting sends the show back to slide one after its final slide, but it does not set a pace. If someone will advance slides manually, you can skip the timing setup and use the loop option alone. If the presentation is for a lobby screen, event display, or unattended kiosk, set slide timings so it can advance without a presenter.
Add timings if you want automatic playback. Select a slide in the thumbnail pane, then open the Transitions tab. In the Timing group, under Advance Slide, select After and enter how long that slide should remain visible. For example, enter 00:00:08 for eight seconds. Repeat for slides that need different durations. To give every slide the same duration, choose a representative slide, enter the time, and select Apply To All. Review the slides afterward if some need more reading time.
Choose whether mouse clicks should also advance slides. In the same Transitions area, the On Mouse Click option can remain selected if a presenter may need to move ahead manually. For unattended playback, clear it if accidental clicks are a concern, and make sure the After option is selected for every slide. The exact controls can be arranged slightly differently in Mac versions, but look for the slide-advance timing options on the Transitions tab.
Open the show setup dialog. On Windows, select Slide Show > Set Up Slide Show. In PowerPoint for Mac, use Slide Show > Set Up Show if that is the label in your version. The dialog controls how the presentation behaves when it is played; it does not start playback or make the file launch automatically when opened.
Turn on continuous looping. In the setup dialog, find Show options and select Loop continuously until ‘Esc’. This tells PowerPoint to return to the beginning when it reaches the end. Click OK to apply the setting. The Escape key is the normal way to stop a looping show, so make sure the person responsible for the display knows how to exit it.
Choose the show type that fits the display. For a presenter-led show, leave Presented by a speaker (full screen) selected. For an unattended display, you can select Browsed at a kiosk (full screen). Kiosk mode is designed for continuous, full-screen playback and restricts ordinary slide navigation, so use it only when the show has timings and does not depend on someone clicking through the slides. If you need to navigate interactively, keep the speaker option instead.
Save the presentation. Select File > Save after setting the loop and timings. The loop setting and slide timings are part of the presentation setup, so saving matters if you want those choices to be available the next time the file is opened. If you made a separate playback copy, confirm you are saving that copy rather than overwriting the source deck by mistake.
Test the whole show from the beginning. Open the Slide Show tab and select From Beginning. Watch at least one full pass, or use a short test copy if the real timings are long. Check that the first slide advances as expected, the final slide returns to the first, and media or animations do not disrupt the timing. Press Esc to leave the show.
Set up the computer for an unattended display, if needed. Connect the screen or projector, select the correct display arrangement, and adjust the computer’s power settings so it does not sleep or turn off the display during playback. Start the show only after the presentation is on the intended screen. PowerPoint’s loop option repeats the open slideshow; it does not prevent Windows or macOS from sleeping, and it does not automatically launch the file after a restart.

Mac note: PowerPoint for Mac uses the same basic approach: set timings on Transitions, open the show setup command from the Slide Show menu, and enable the continuous-loop option. Ribbon group names and dialog wording can vary slightly by release. If you cannot find the setting, make sure the file is open in the desktop app and check the Slide Show menu rather than assuming the browser version has the same controls.

Common Mistakes

Confusing a loop with automatic slide advance. Looping controls what happens after the last slide. Without timings, a show may wait for a click on each slide and never reach the end on its own. Add and test timings for hands-free playback.
Setting a timing on only one slide. A slide with no advance time may wait indefinitely during a self-running show. Use Apply To All for a uniform pace, or inspect every slide if the timings should differ.
Choosing kiosk mode for a presentation that needs a presenter. Kiosk mode limits ordinary navigation. If you want to move around freely during a talk, use the speaker show type and turn looping on without kiosk mode.
Forgetting to save or test the saved copy. It is easy to configure one copy and then play another. Save the intended file, close it if practical, reopen that same file, and run the show to confirm the behavior.
Assuming the slideshow will start by itself. The loop option repeats a show after you start it. It does not automatically open PowerPoint or begin playback when the computer starts.

Tips

Choose timings based on how people will view the screen. A photo or title slide may need only a few seconds, while a slide with instructions or detailed text needs longer. Stand at the viewing distance and check whether the content can be read before it advances.
Use a deliberate ending. When the show loops, the last slide leads directly back to the first. Make that transition feel intentional—for example, end with a short closing slide that visually connects to the opening slide.
Check videos and animations in slideshow mode. Embedded media may have its own playback settings, and a video can take longer than the slide’s advance time. Test the complete slide, not just its static appearance, before leaving the display unattended.
Keep a copy that is easy to stop. Escape exits the running show. If other people will operate the display, give them the file name and a brief instruction to press Esc when they need to end playback.
Test on the actual screen when possible. Text that is clear on a laptop may be difficult to read on a distant display. Check the aspect ratio, fonts, and audio on the equipment that will be used for the real presentation.

Troubleshooting

The show stops on the last slide instead of restarting. Reopen Slide Show > Set Up Slide Show on Windows, or the equivalent setup command on Mac. Confirm that Loop continuously until ‘Esc’ is checked, select OK, save the file, and start the show from the beginning. If you are playing a different copy, make the change in the file you actually use.
The slides do not advance on their own. Check the Transitions tab on each slide. The After checkbox must be selected and have a time entered. If you used Apply To All, verify that the timing was applied and not later removed on an individual slide. Also make sure the show is not waiting for a click because only manual advance is configured.
Slides advance too quickly or too slowly. Adjust the duration under Transitions > Timing > Advance Slide > After, then test again. If timings vary by slide, select each slide in the thumbnail pane and check its individual value; applying one time to all can overwrite intentionally longer timings.
The show starts in a window or on the wrong display. Review the show type in the setup dialog. Choose the full-screen speaker or kiosk option as appropriate, then check Windows display settings or macOS display arrangement and select the screen where the show should appear. The names and controls for display settings differ between operating systems.
PowerPoint or the computer interrupts playback. Check whether the computer is sleeping, the display is turning off, a notification is covering the screen, or a video is waiting to load. Adjust power settings for the duration of the event and test media with the same network and equipment you plan to use. If the presentation relies on online content, prepare a local or offline alternative where possible.
The loop setting is unavailable or behaves differently. Confirm that you are using the desktop version of PowerPoint and that you are in Slide Show setup rather than editing a transition. If you are using PowerPoint for the web, open the file in the desktop app for the full setup controls. Menu labels can differ by version, so look for the Set Up Show command under the Slide Show menu.

Frequently Asked Questions

Can I loop a PowerPoint without setting slide timings?
Yes. Enable Loop continuously until ‘Esc’ and start the show. You can advance slides manually, and the presentation will return to the beginning when you reach the end. Timings are needed only if you want slides to advance without clicks.

Will the slideshow loop automatically when I open the file?
No. The loop setting controls playback after you start the slide show; it does not launch PowerPoint or start the show when the file opens. For an unattended setup, start playback and separately configure the computer to stay awake.

How do I stop a PowerPoint slideshow that is looping?
Press Esc while the slideshow is active. This exits the show and returns you to the PowerPoint editing view. In kiosk mode, Escape is also the normal exit key.

Can I loop only part of a presentation?
PowerPoint’s continuous-loop setting repeats the show being played. To repeat only selected slides, create a custom show from the slides you want, then configure and play that custom show. Check the custom show from beginning to end to make sure its sequence and timings are correct.

Does the loop setting work on both Windows and Mac?
Yes, the desktop versions of PowerPoint for Windows and Mac provide a continuous-loop setting in their slideshow setup controls. The menu wording and placement can vary slightly, so use the Slide Show menu and look for Set Up Slide Show or Set Up Show.

Will the presentation keep looping if the computer goes to sleep?
No. PowerPoint cannot keep a sleeping computer displaying the show. Adjust the computer’s power settings so it remains awake, and check that the monitor or external display does not switch off during the planned playback period.
