How 25/5 Pomodoro works
A 25/5 Pomodoro is 25 minutes of focused work followed by a 5-minute break. After four rounds you take a longer break of 15 minutes. It is the classic interval of the Pomodoro Technique: short enough that starting feels easy, long enough to make real progress on one task.
- Write down the one task for this round.
- Start the 25-minute focus block and work only on that task.
- If a distraction comes up, note it in a few words and carry on.
- When the chime sounds, take a 5-minute break away from the screen.
- Repeat. After the fourth round, take the 15-minute long break.
Prefer 30/5?
Pick 30/5 at the top of the page: 30 minutes of focus, then a 5 minute break, with a 15 minute break after 4.
A slightly longer Pomodoro for when 25 minutes ends just as you settle in. Half-hour blocks also line up with a calendar.
- People who find 25 minutes slightly too short
- Reading and note-taking
- Work planned in half-hour calendar slots
- A first step toward 50/10
Where it comes from
Francesco Cirillo created the Pomodoro Technique in the 1980s. In his words, he built it "with a tomato-shaped kitchen timer and a problem: I couldn't focus on my university studies" (Cirillo). The standard cycle is 25 minutes of work, a short break of about 5 minutes, and a long break after four rounds, usually given as 20 to 30 minutes (Wikipedia) or 15 to 30 (Zapier).
Cirillo stresses that the 25-minute timer is only one part of the method, which also covers daily planning, handling interruptions and estimating effort. Twenty-five minutes is a convention that works for many people, not a measured optimum.
What the evidence says
There is reasonable evidence that scheduled breaks help, but none that 25 minutes is the ideal length. In a 2023 study (Biwer et al., 2023), 87 university students studied for a day with either self-chosen breaks or fixed breaks (a 24/6 Pomodoro-style schedule or 12/3). Those who chose their own breaks studied in longer stretches and reported more fatigue and distraction and less concentration and motivation; the amount of work completed was similar (Biwer et al., 2023).
A 2025 scoping review of Pomodoro studies in education reported consistent benefits for focus and mental fatigue, while noting varied study designs, mostly short-term outcomes, and that fixed timing may interrupt tasks that need long, intensive focus (Ogut, 2025).

It is the length Francesco Cirillo used when he created the technique as a student in the 1980s. There is no evidence that 25 minutes is optimal. It is short enough to start without negotiating with yourself, which is its main strength.
Something different from the work: stand up, get water, look out of a window, stretch. Scrolling a feed rarely feels like a break and tends to run over.
Write one line about where you are and take the break anyway. The note makes it easy to pick up again. If this happens every round, try the 50/10 interval for that kind of work.
There is no right number. Start with what you can sustain, for example four rounds and one long break, and add rounds as it gets easier rather than forcing a target.
Yes. Switch this timer to its 30/5 option: 30 minutes of focus, 5-minute breaks and a 15-minute long break after four rounds. No study has compared 30/5 with 25/5; it is simply an easy step up if the chime keeps interrupting you just as you get going.
