25 minute Pomodoro timer
The 25/5 pattern is the one Cirillo described: 25 minutes on a single task, a 5-minute break when the timer rings, and a longer break after 4 pomodoros. This page sets that long break at 15 minutes, the low end of the range many guides give, about 15 to 30 minutes. Wikipedia (retrieved 2026-09-20) puts it at 20 to 30.
25 minutes is short enough that starting feels cheap and long enough to get a page written, a set of flashcards through, or one bug fixed. The break is a real pause, not a scroll through your phone: stand up, get water, look out a window. The original method treats a pomodoro as indivisible, so if something interrupts you, note it and come back to it after the block ends.
This interval suits people trying the technique for the first time, and anyone whose work splits into small pieces. It is a poor fit for work that needs a long warm-up, such as reading dense material or holding a large problem in your head, because the break arrives before you have settled in. For that, try 50/10 or 45/15.
Questions
is 25 minutes the right pomodoro length
It is the default, not a rule. Cirillo set the timer for about 25 minutes, but the point is a fixed block you do not negotiate with. If 25 feels short, try 30/10 or 50/10 and keep the break honest.
what do you do during a 5 minute pomodoro break
Leave the task and, ideally, the chair. Water, a stretch, a window. 5 minutes is not long enough to start anything else, and that is the point. Avoid your inbox, because one email turns 5 minutes into 20.
does the 25 5 pomodoro technique actually work
The evidence is mixed. Ogut (2025) reviewed 32 studies and 88% reported better focus or lower fatigue, mostly self-reported. Smits et al. (2025) compared 25/5 with self-chosen breaks in 94 students and found no productivity difference, with motivation dropping faster in the timed groups.
