Twenty-five minutes on and five off, or fifty-two on and seventeen off. The difference is less about the work and more about the breaks.
Pomodoro is better for starting; 52/17 is better for staying. If your trouble is getting going, 25 minutes is an easier promise. If you can already hold focus past the warm-up, 52 minutes wastes fewer of them — but only if you actually take the long 17-minute break.
| Pomodoro 25/5 | 52/17 | |
|---|---|---|
| Focus block | 25 min | 52 min |
| Break | 5 min (15 after four) | 17 min, every time |
| Focus per hour | ~50 min | ~45 min |
| Warm-ups per 3 hours | About 6 | About 3 |
| Origin | Designed (Francesco Cirillo) | Observed in time-tracking data |

Plenty of people use Pomodoro to get going in the morning and switch to 52/17 once they are in. Others use 25/5 for email and admin, and 52/17 for their one important task. The rhythms are tools, not identities.
It depends on the work. For deep tasks, 52/17 usually wins because it needs fewer warm-ups. For starting and shallow work, Pomodoro usually wins because it lowers the barrier to begin.
Because that is what the most productive people in the data did — they fully stepped away. The long break is what makes the next 52 minutes work, so it is the part worth keeping.
Yes, if it lets you set custom lengths. The 52/17 timer here is pre-set to exactly that rhythm.
