Sand Timer

Share to Google ClassroomPosts this timer, set to 3 minutes, to your class.

Share a timer: add ?t= and the number of seconds to the address, e.g. visualtimer.org/?t=420 for 7 minutes.

Like a real hourglass, the sand drains from the top to the bottom as time passes — but this one can be set to any length, from a few seconds to an hour, and it plays a chime when it’s done.

Sand timers are calm and easy to read, which makes them popular in classrooms, speech therapy and board games.

Ideas for using it

How to use the timer

  1. Tap a time (or type your own, like 7, 2:30 or 1h 15m) and press Start.
  2. Use Full screen on a supported browser to show the timer on a projector, smartboard or TV. Check the actual display before relying on it.
  3. When the time is up, the timer shows Time’s up! and attempts to play a chime if sound is on. Keep the device awake and test the audio first. Reset prepares another round.

Frequently asked questions

How long is a normal sand timer?

Physical sand timers usually come in 1, 3, 5 and 10 minutes. This one can be set to any time.

Will the timer keep running if I switch tabs?

The timer calculates the remaining time from an end time and can catch up after a delayed update. Browsers can throttle or suspend hidden pages, so an alarm may be delayed. Keep the timer visible and the device awake when timing matters; sleeping devices and closed tabs are not supported.
