The 52/17 rule: where it came from and whether to use it
Short answer: the 52/17 rule means working for 52 minutes, then resting for 17. It came from one company's app data in 2014, not from a controlled experiment. It suits deep, warm-up-heavy work better than 25/5 pomodoro does. It is also a schedule with more rest than pomodoro, not less.
What the 52/17 rule is
You work on one thing for 52 minutes with no email or chat, then step fully away for 17 minutes, then repeat. That's the whole rule. There's no long break after a set number of rounds, as pomodoro has. Every break is already long.
Where the numbers came from
In 2014 the time-tracking company DeskTime looked at the computer-use logs of its most productive users (the top 10% by its own productivity score). On average those people worked for about 52 minutes and then took a break of about 17. The story spread quickly because the numbers are oddly specific.
Three things are worth knowing before you treat it as science:
- It's observational. It shows what productive people happened to do. It doesn't show that switching to 52/17 will make you more productive.
- "Productive" was DeskTime's own measure, based on time spent in apps it labelled productive.
- The numbers moved. When DeskTime ran the analysis again in 2021, the top group averaged about 112 minutes of work and 26 minutes of rest.
What the two runs do agree on is the shape: long, uninterrupted blocks of work followed by real, sizable breaks. That shape is the useful part. The exact minutes matter less.
52/17 vs 25/5 pomodoro
| Pomodoro 25/5 | 52/17 | |
|---|---|---|
| Work block | 25 min | 52 min |
| Short break | 5 min | 17 min |
| Long break | 15–30 min after 4 rounds | none (every break is long) |
| Share of time working | about 80%* | about 75% |
| Rounds in a 4-hour block | about 8 | about 3½ |
| Good for | starting, admin, tasks you avoid, ADHD-friendly short sprints | writing, coding, design: work that needs 10–15 min just to warm up |
*Four 25-minute rounds, three 5-minute breaks and one 20-minute long break: 100 of 135 minutes.
The surprise in that table is that 52/17 has you resting slightly more than classic pomodoro. You just rest in fewer, bigger pieces.
Who 52/17 suits, and who it doesn't
Try it if
- your 25-minute timer keeps ringing just as you finally get into the work;
- your work has a long ramp-up (holding a big piece of code or an argument in your head);
- you can genuinely leave your desk for a long break.
Stick with 25/5 if
- starting is your real problem: 25 minutes is easier to say yes to than 52;
- you drift after 20–30 minutes (see pomodoro for ADHD);
- your day is full of small tasks that don't need a long block.
If neither fixed length fits, try a timer that follows your focus instead of setting it: the Flowtime technique lets you work until your focus fades, then gives you a break sized to match.
How to use the 17-minute break
Seventeen minutes is long enough to do something genuinely restful and short enough to come back from. Good uses: a walk, making tea, stretching, a short chat with someone, looking out the window. The one to avoid is the phone scroll. It's easy to start and hard to stop, and it doesn't rest the attention you just spent. More on that in how long a break should be.
Trying 52/17 in hokkori
- Open settings (the gear).
- Set focus to 52 and short break to 17.
- Set long break to 17 too, so every break is the same.
Run it for a week, then compare with your usual rhythm in the stats panel. Whichever one you actually finish more rounds with is the right one for you.
Questions people ask
Is the 52/17 rule better than the pomodoro technique?
Neither is better in general. 52/17 tends to suit long, deep tasks. 25/5 tends to suit getting started and short attention spans. The data behind 52/17 is observational, so it can't show that one beats the other.
Is the 52/17 rule scientifically proven?
No. It comes from DeskTime's analysis of its own users in 2014, and a 2021 rerun found different numbers (about 112/26). Research on breaks in general does support stepping away regularly. It doesn't single out 52 and 17.
Can I do 50/10 instead?
Yes. 50/10 is a popular round-number version. The main idea is a long work block followed by a break you actually take. Adjust the numbers until you finish the work block still able to think.
What about the newer 112/26 numbers?
Two hours of unbroken focus is a lot for most people. Treat it as a ceiling some people reach on good days, not as a target.
