How Long Is a Pomodoro?
A pomodoro is 25 minutes of focused work, followed by a 5-minute break. After four of them you take a longer break of 15 to 30 minutes. One session plus its short break is 30 minutes, which makes the maths easy: two pomodoros to an hour.
The full cycle, not just the session
People ask how long a pomodoro is and then plan their afternoon as though four of them take one hour forty. The breaks are part of the clock.
Four sessions with their breaks run 1 hour 55 minutes end to end. Eight run 4 hours 5 minutes. That gap between the work time and the wall-clock time is where most pomodoro plans fall over.
The 25/5 pomodoro page has the block-by-block breakdown if you want to see where every minute goes.
Where 25 comes from
Francesco Cirillo picked it as a university student in the late 1980s, testing short study bursts against a tomato-shaped kitchen timer, which is also where the name came from (Wikipedia). He started at ten minutes and worked up. No experiment chose the number, and why 25 minutes goes through the reasoning and the research in full.
Cirillo’s rule is that a pomodoro is indivisible. Half a pomodoro does not exist, and a session broken by something urgent is either recorded and resumed or written off and started again.
Common lengths people actually use
25/5 is the original and still the best default for anything you are avoiding.
50/10 doubles it and suits work with a slow warm-up, like debugging or editing. Fewer switches per hour, and one decision to start instead of two. See 50/10.
52/17 came out of DeskTime’s analysis of its own users in 2014, where the most productive tenth averaged 52 minutes of work and 17 of break. The break is longer than people expect, and that is the interesting part.
90 minutes maps to a single deep block with no interruptions, usually two a day at most. See 90-minute focus sessions.
10 to 15 minutes is the right answer on days when the problem is starting rather than sustaining. Short, finished sessions beat long, abandoned ones.
All of them sit side by side on the pomodoro intervals page.
FAQ
How long is a typical pomodoro session?
Twenty-five minutes of work, then a five-minute break. Four sessions make a set, ending with a long break of 15 to 30 minutes. Counting the breaks, a set of four takes 1 hour 55 minutes of real time, which is the number to use when planning a day.
How long is the long break?
Fifteen to thirty minutes after every four sessions. Wikipedia’s summary of the method gives 20 to 30. Pick a length you will come back from, since the long break is the one most likely to turn into an afternoon.
Can a pomodoro be 30 minutes?
Yes, and plenty of people use 30/5 so that a session plus break lands on a neat half hour. Purists will tell you 25 is the definition. If a longer block matches how your work loads into your head, the label matters less than finishing the session.
How many pomodoros are in an hour?
Two, counting breaks: 25 plus 5, twice over. Three sessions in an hour means cutting the breaks, which is the pattern that leaves people wrung out by mid-afternoon. How many pomodoros per day covers the daily maths, including why eight sessions eat most of a working day.
Does the break count as part of the pomodoro?
Cirillo counts the pomodoro as the 25 minutes of work. The break belongs to the cycle rather than the session. For planning purposes, always add the breaks, because a five-session afternoon is nearly three hours of clock time.
Set the classic length and see how it fits your work. Start a 25/5 session with a long break after four, or open the plain 25-minute timer.
