What this page is set to
This page opens with the timer already set to the values below. Nothing to configure — just press start.
One full cycle of 2 focus sessions runs 146 minutes, 104 of which is focus time. Fill an eight-hour day with this split and you spend roughly 5.7 hours focused across about 7 sessions.
You can change any of these numbers under timer settings. Changes are saved for this page only, so they never overwrite the settings on the home page or on another preset.
- 52-minute focus
- 17-minute short break
- 25-minute long break
- Long break after every 2 focus sessions
Where the numbers came from
The split entered circulation when the time-tracking company DeskTime published an analysis of its own users, reporting that the most productive segment averaged about 52 minutes of work followed by about 17 minutes away from the desk.
That is log analysis of one company's customers, not a controlled study, and the sample leans heavily toward desk-based knowledge work. There is nothing magic about 52 or 17 specifically. What is worth taking from it is the shape: a focus block a little under an hour, paired with a break long enough to actually leave the desk.
Why it still works in practice
Whatever the provenance, the combination is a sensible one. Fifty-two minutes sits close to the ceiling most people can hold at full density, and seventeen is enough to stand up, walk somewhere and come back reset. Treat it as the midpoint between 45/15 and 50/10.
- A cycle runs 69 minutes, so it will not align with a calendar. On a meeting-heavy day, 60/10 fits better.
- It suits remote work, where you control the shape of your own day.
- Seventeen minutes is about right for a short walk outdoors.
- Run it for two days, then adjust the numbers to whatever your own attention actually does.
How to find your own split
The genuinely useful lesson in 52/17 is the method, not the numbers: someone looked at what productive people actually did and derived a rhythm from it. You can do the same with your own data.
Work with this split for a week and note two things after every session. Roughly how many minutes in did your attention first wander? And when you sat back down after the break, did you get straight back into it? Rough minutes are fine — this is not a lab.
At the end of the week, the average of the first number is a realistic length for your focus block; add about five minutes and use that. If the second note often says re-entry was hard, your breaks are too short. If you were regularly bored by the end of the break, they are too long. Numbers you get this way will fit you far better than an average from somebody else's users.
- Measure similar kinds of work separately. Averaging writing and inbox triage gives you a number that fits neither.
- Flag days after a bad night's sleep and leave them out of the average.
- Put your numbers into this page's timer settings — they are saved for this page only.
Questions about the 52/17 timer
Is 52/17 scientifically proven?
No. It comes from averages in one time-tracking app's user logs, not a controlled experiment. Treat it as a useful pattern rather than a finding.
Do I have to hit exactly 52 minutes?
No. Fifty or fifty-five makes no meaningful difference. Change it in the timer settings.
Does it work for studying?
It can. But since the numbers came from office work, exam prep is better served by matching the length of the real paper.
