What it's good for

What 40 minutes is good for.

  • Class periods

    Many schools run 40 to 45 minute lessons. Put the countdown on the board so the class can pace the last activity.

  • Exam practice

    Time a section of a past paper under real conditions, without reaching for your phone to check the time.

  • Free video calls

    Zoom's free plan ends meetings at 40 minutes. A visible countdown means you wrap up before the call does it for you.

40 minute timer questions

How do I start a 40 minute timer?

Press Start, or the space bar. The 40 minutes count down in big digits and the time left shows in your browser tab, so you can switch to other work and still see it.

Why do some video calls stop at 40 minutes?

Zoom's free plan limits meetings with other people to 40 minutes, so a visible countdown helps you wrap up in time. Our comparison of free video calls lists the limits of Zoom, Google Meet, Teams and others.

Does the 40 minute timer make a sound?

Yes, a soft two-note chime at zero, made in your browser without any audio files. Turn it off with the bell button. It still chimes on time in a background tab, because the sound is scheduled when you press Start.

Can I show it full screen?

Yes. Press F or the full screen button and the digits fill the screen, big enough for a whole room. Escape takes you back.

Do I need to sign up or install anything?

No. The timer is free and runs in your browser on a laptop, tablet or phone. No account, no email, no download.
