20 minute timer

Twenty minutes for a short study block, a workout or a reset of the kitchen, with big digits you can read from across the room.

Ways to use a 20 minute timer

Twenty minutes is a good first focus block for anyone who finds 25 too long. It is also a common length for a home workout: put the timer in fullscreen on a laptop at the side of the room and you can see the time left from your mat. The digits stay readable at a distance in both light and dark themes.

For revision, twenty minutes fits one past-paper question with time to mark it. Parents use it for homework: twenty minutes of reading, then a break. Short blocks are much easier to start, and starting is often the hardest part.

For a gentler study rhythm, the study timer chains focus sessions and breaks for you. If you are timing a workout, turn sounds off and let your own music play in another app; the chime still sounds at the end.

Make the most of 20 minutes

Twenty minutes rewards a little preparation. Lay out what you need before pressing Start: the workout mat and water, the flashcards, the cleaning spray. For workouts, warm up before you start the timer so the twenty minutes are all effort. For study, write the question you want to answer at the top of the page; by the chime you should be able to answer it without notes. Parents can use the end time shown under the clock to agree when homework stops. If twenty minutes always feels too short, try two in a row with a five-minute gap, which is close to the classic Pomodoro rhythm.

How this timer works

Press Start or Space to begin and again to pause. R resets, F opens fullscreen, M mutes sounds and ? lists every shortcut. Change the minutes box to adjust the length. The line under the timer shows the clock time it will end. Sounds play only after you switch them on, and they fade out when time is up. Want breaks after this? Continue as a Pomodoro cycle.

Frequently asked questions

Is 20 minutes a good study session?

For many people, yes, especially when starting out or when tired. If you often want to keep going at the chime, try 25 or 30 minutes.

Can I use it for a workout?

Yes. Fullscreen shows large digits you can read from a distance. For interval rounds you will need a separate interval timer, as this one counts a single block.

Can I play my own music?

Yes. Leave our sounds off and play music in another app or tab. The timer and its chime work independently.

Does the screen stay on?

In fullscreen the timer asks the browser to keep the screen awake, where the browser supports it. Otherwise, check your device’s sleep setting.

How do I see what time 20 minutes from now is?

Look at the line under the timer. Before you start it shows what time it will be in 20 minutes; while running it shows the end time.
