45/15 Pomodoro Timer

The 45/15 timer: 45 minutes of focused work, a 15-minute break, repeated for four rounds. It is a popular middle ground between the classic 25-minute Pomodoro and the longer 52/17 — long enough to settle into a chapter, a problem set, or a writing task, with a generous break to reset between rounds.

The 3-to-1 ratio of work to rest is an easy one to plan a study session around: four rounds fill an afternoon almost to the hour. Press start and the timer runs each focus block and break in turn, or open the editor to shorten the blocks, change the break, or add rounds.

Frequently Asked Questions

How long is the 45/15 session?
Four rounds of 45 minutes of focus with a 15-minute break between them, ending on the fourth focus block — three hours and forty-five minutes in total. Adjust the round count in the editor for a shorter or longer session.
Is 45/15 good for studying?
Yes — 45 minutes is long enough to get deep into a topic without the fatigue of a marathon session, and the 15-minute break is enough to rest properly before the next round. Use it as a study timer for revision, reading, or problem sets.
How is this different from 25/5?
Same rhythm, longer blocks. 25/5 suits tasks you want to start quickly or short bursts of focus; 45/15 suits work that takes longer to get into and benefits from fewer interruptions.
