How to Insert a Timer into Google Slides (Text Box Method)

Quick Summary: 3 Steps to Add a Timer

Step 1

Install Live Slides Timer

Add the free extension from the Chrome Web Store so tags can animate in presentation mode.

Step 2

Insert → Text box (or click an existing box)

Place the box where the audience should see the timer—corner, banner, or center.

Step 3

Type the timer tag and present

Enter {{5:00-}} (or another duration), style the font, then click Slideshow to start the live countdown.

The Short Answer

To insert a timer into Google Slides, install Live Slides Timer, add a text box, type a tag such as {{5:00-}}, then click Slideshow. During presentation the tag becomes a live countdown. You do not need Insert → Video or a YouTube search.

Step-by-Step: Text Box Insertion

Install Live Slides Timer from the Chrome Web Store (Chrome, Edge, Brave, Opera).
Open your deck in Google Slides.
Choose Insert → Text box (or reuse an existing box).
Type one of these tags:
- {{5:00-}} — 5-minute countdown
- {{1:00-}} — 1-minute countdown
- {{0:00+}} — stopwatch from zero
- {{now}} — live clock
Format size and color like any other text (48pt+ for classrooms; brand colors for decks).
Click Slideshow. The insert is live.

Where Should You Place the Timer on the Slide?

Upper right — stays visible without covering titles (default teaching layout).
Center of a dedicated “timer slide” — great for group work or breaks.
Footer strip — subtle pacing for keynotes without dominating the visual.

Insert Timer + Sound or Next Slide

After you know the basic insert, chain actions with pipes:

{{5:00-|@}} — insert countdown that rings a bell at zero
{{5:00-|]}} — insert countdown that advances to the next slide
{{5:00-|@|]}} — bell and auto-advance together

Need help building the string? Use the Tag Generator, then paste into the text box.

Why Not Insert → Video?

Inserting a YouTube countdown feels familiar but introduces ads, network dependence, and fixed lengths. Text-box tags stay lightweight, match your slide typography, and support exact durations like 3:42.

Frequently Asked Questions

Can I insert more than one timer on the same slide?

Yes. Each text box (or each tag inside a box) can hold its own countdown or clock. Keep layouts readable so the audience is not distracted by multiple clocks.

Does the timer stay if I share the deck with colleagues?

The tag text is saved in the slide. Viewers need Live Slides Timer installed on the presenting browser for the tag to animate during Slideshow. Without the extension, collaborators still see the raw tag text in edit mode.

How do I insert a timer that starts paused?

Append |$ to a countdown tag, for example {{5:00-|$}}. The timer waits in Slideshow until you press Y to start. Scheduled wall-clock starts use a longer |$MM#HH#*#*#* form documented in the syntax guide.
