The Pomodoro Technique · Part 2
How Long Is a Pomodoro: 25/5, 15/3 or 50/10
The classic 25 minutes don't suit everyone or every task. Three proven pomodoro rhythms — 25/5, 15/3 and 50/10 — how to pick yours and when to change it.
A classic pomodoro is 25 minutes of work and a 5-minute break, with a 15-minute long break after four pomodoros. It’s a convenient number to start with, not a law: 15/3 suits the first days, and 50/10 suits tasks that take a while to get into.
If you keep breaking off at minute fifteen, or you’re only just getting into the task when the timer rings, change the rhythm instead of putting up with it.
What a rhythm is made of
A rhythm is four numbers:
- pomodoro — minutes of work;
- short break — rest between pomodoros;
- long break — rest after a cycle;
- pomodoros per cycle — how many pomodoros before the long break.
Tuning all four from scratch is tedious, so it’s easier to start from one of the ready-made options.
Three rhythms to start with
| Rhythm | Pomodoro | Break | Long break | Pomodoros per cycle |
|---|---|---|---|---|
| Gentle Start | 15 min | 3 min | 10 min | 4 |
| Classic | 25 min | 5 min | 15 min | 4 |
| Deep Focus | 50 min | 10 min | 20 min | 3 |
Classic is Cirillo’s own rhythm. It fits most work: writing, sorting things out, calculating, preparing. When in doubt, pick this one.
Gentle Start is for the first days and for hard stretches. Twenty-five undistracted minutes are unexpectedly hard for someone who has worked with chat open for years. Fifteen minutes are easier to get through, and a habit grows from pomodoros you finish, not from ones you abandon.
Deep Focus is for tasks that take a while to get into: programming, a difficult text, design. If warming up takes ten minutes, a 25-minute pomodoro leaves only fifteen for the work itself. The cycle is shorter here — three pomodoros: after nearly three hours of continuous work you need the long break sooner.
How to tell the rhythm isn’t yours
Look at interrupted pomodoros over the last week — a week, not one bad day.
- You often stop before the timer — more than a third of pomodoros don’t make it to the end. The pomodoro is too long: cut five minutes. A short pomodoro finished is worth more than a long one dropped halfway.
- A week on a short rhythm without a single interruption — time to add five minutes. Gentle Start is a step, not a place to stay.
- The timer keeps catching you in full flow and it annoys you every time — try Deep Focus. But be honest with yourself: are you just trying to skip the rest?
- You’re drained by evening even though pomodoros go smoothly — lengthen the breaks, not the pomodoros.
Change one number at a time and live with it for at least a few days: one day isn’t enough to judge a rhythm.
Breaks matter more than they seem
The most common mistake is “saving” a break: the timer rang, things are going well, I’ll keep going. Once, it costs nothing. All day long, and by evening you work noticeably slower — and you only notice it from the results. A short break is five minutes away from the screen. A long one is time to eat, step outside, talk to someone.
In the app
Pomodoro offers these three rhythms on first launch, and you can switch any time in Settings, where all four numbers can also be tuned one by one. The app keeps an eye on interrupted pomodoros: if many piled up over a week, it suggests a pomodoro five minutes shorter, and after a week without interruptions on Gentle Start — a longer one.
The next part is about what to do when a pomodoro does get interrupted: distractions and interruptions.
