Google Slides has a built-in timer you can show your audience or keep private

Google Slides does not have a timer feature built into the presentation itself, but you can add one in two ways: use the Speaker Notes timer that only you see during a presentation, or embed a web-based countdown timer as a visible slide element that your audience watches. The Speaker Notes timer is the faster route if you just need to track your own pacing. The embedded timer works if you want to show your audience how much time remains for a question, activity, or segment.

Both methods work on any device where you can open Google Slides — desktop, tablet, or phone — though the embedded timer approach gives you more control over appearance and visibility.

Key Takeaways

  • The Speaker Notes timer appears only on your screen during a presentation and tracks elapsed time automatically once you start presenting.
  • To show a visible countdown timer to your audience, you embed a web timer as an iframe or use a Google Slides add-on designed for this purpose.
  • The easiest embedded timer option is the "Countdown Timer" or "Timer" add-on from the Google Workspace Marketplace, which you install once and reuse across presentations.
  • A countdown timer works best when you set it before the presentation starts, because adjusting it mid-presentation requires pausing to edit the slide.
  • If you need a timer that syncs across multiple devices or integrates with other tools, a separate browser tab running a web timer is often simpler than embedding.

Using the Speaker Notes timer to track your own pacing

When you present a Google Slides deck in Presenter View, a timer appears automatically in the bottom left corner of your screen. This timer shows how long you have been presenting and is visible only to you, not to your audience. To access it, open your presentation, click the Present button (or press Ctrl+Alt+F on Windows, Cmd+Shift+F on Mac), and the timer starts counting from zero the moment the presentation begins.

You can reset this timer at any point during the presentation by clicking on the timer itself. This is useful if you want to restart the clock for a new section or activity. The timer keeps running whether you are on a slide with speaker notes or not, so it works as a general pacing tool for your entire presentation.

The Speaker Notes timer does not require any setup or add-ons. It is always there once you enter Presenter View. The trade-off is that only you see it — your audience has no way to know how much time has passed or remains.

Embedding a visible countdown timer on a slide

If you want your audience to see a countdown timer, you need to add it as a slide element. The most straightforward method is to use a Google Slides add-on. Open your presentation, click Extensions in the menu bar, then select Add-ons and search for "Timer" or "Countdown Timer." Several free options appear — Countdown Timer and Timer for Slides are both reliable choices. Install the one you prefer, and it will appear in your Extensions menu from that point forward.

Once installed, click Extensions > the timer add-on name > Insert Timer. A dialog box opens where you set the duration in minutes and seconds. After you confirm, the timer appears on your current slide as a visual element — usually a large, straightforward-to-read display. You can resize and reposition it like any other object on the slide.

When you present the slide, the timer counts down automatically and is visible to everyone in the room. Some add-ons let you pause or reset the timer during the presentation; others require you to stop presenting, edit the slide, and resume. Check the add-on's description to see which controls it offers before you install.

Embedding a web-based timer without an add-on

If you prefer not to install an add-on, you can embed a countdown timer from a public web service. Open your presentation, click Insert in the menu, then select Embed. Paste the embed code from a timer website such as Online-Stopwatch.com, Timer-Tab.com, or Timeanddate.com. Not all timer sites provide embed codes, so check their settings or help section first.

The embedded timer appears on your slide and counts down when you present. The advantage of this method is that you control the exact look and duration of the timer. The disadvantage is that you have to find a timer site that offers embed codes, and some sites change their code format or remove the feature without notice.

A simpler alternative is to open a timer in a separate browser tab while you present. This keeps your Google Slides presentation clean and lets you use any timer website you like. You can switch between the timer tab and your presentation using Alt+Tab (Windows) or Cmd+Tab (Mac), or use a second monitor if you have one.

Choosing between a speaker timer and a visible timer

Use the Speaker Notes timer if you are the only person who needs to know the time — for example, if you are giving a talk and want to stay on schedule without your audience noticing you are watching the clock. This timer requires no setup and is always available.

Use a visible countdown timer if your audience needs to see how much time remains — for a group activity, a Q&A session, a quiz, or a timed exercise. A visible timer creates accountability and helps people pace themselves. It also removes the need for you to announce "five minutes left" or "time is up" because the timer does that work for you.

If you use a visible timer, set it up and test it before the presentation starts. Adjust the duration on a practice run so you know exactly how long the countdown takes. If you need to change the duration during the presentation, pause, edit the slide, and resume — this interrupts the flow, so it is worth getting the timing right beforehand.

Troubleshooting common timer problems

If an add-on timer does not appear on your slide after you insert it, refresh the page and try again. Some add-ons take a few seconds to load. If the timer still does not show, check that you have granted the add-on permission to access your presentation — Google will prompt you the first time you use it.

If a visible timer does not count down during your presentation, make sure you are in Presenter View or full-screen presentation mode, not just viewing the slide in edit mode. Timers often do not animate in the editor; they only work when you present. If the timer is embedded from a website and still does not work, the website may have changed its embed code or blocked embedding — try a different timer site.

If you are presenting on a projector or shared screen and the timer is hard to see, make the timer larger by dragging its corners, or choose an add-on with a bold, high-contrast design. Test the visibility in the actual room or on the actual screen before your presentation starts.

Frequently Asked Questions

Can I set a timer that counts up instead of down?

Yes. Most timer add-ons and web timers let you choose between countdown and stopwatch (count-up) mode in their settings. If the add-on you installed does not offer this option, try a different one from the Google Workspace Marketplace, or use a web timer like Online-Stopwatch.com, which has both modes built in.

Will the timer keep running if I switch to a different slide?

If the timer is embedded on a specific slide, it stops when you move to the next slide. If you need a timer that runs across multiple slides, use the Speaker Notes timer (which runs for your entire presentation) or open a timer in a separate browser tab and switch back to it as needed.

Can I use a timer on a phone or tablet?

Yes, but it is less practical. The Speaker Notes timer works on any device in Presenter View. Embedded timers and add-ons also work, but on a small screen it is harder to see and adjust. If you are presenting from a phone or tablet, a separate timer app on another device is often easier than embedding one in the slides.

What if my add-on timer does not sync across devices?

Add-on timers are tied to the slide itself, not to a shared clock, so if you present from one device and someone else views the presentation on another device at the same time, their timer may not match yours. For synchronized timing across devices, use a web-based timer in a separate tab that everyone can see on a shared screen or projector.
