45 minute Pomodoro timer
The 45/15 Pomodoro timer alternates 45 minutes of work with 15-minute breaks, and adds a 30-minute break after every 4 rounds. The cycle repeats for as long as you keep going. Unlike the 4 x 45 session, this page has no end point. You decide when the last round is.
The numbers match a lot of real schedules. A lecture slot, a tutoring session, and a school period are all close to 45 minutes, so the block feels familiar rather than arbitrary. The 15-minute break is a proper pause: long enough to make a meal, take a walk around the block, or return a call without feeling rushed.
45/15 suits students revising for exams, and anyone who finds 10-minute breaks too short to come back rested. Do not use it if your breaks tend to stretch, because 15 minutes turns into 40 more easily than 5 does, and a 45-minute block is not worth much if you take an hour off after it. A tighter 40/10 keeps that in check.
Questions
is 45 15 a good pomodoro ratio
45/15 is a 3-to-1 ratio, more generous with rest than 25/5, which is 5-to-1. None of the research settles a best ratio. Pick 45/15 when 10-minute breaks leave you coming back still tired.
what is the difference between 45 15 and 4x45
Same block, same break. This page repeats until you stop, with a 30-minute break after every fourth round. The 4 x 45 session runs exactly 4 blocks and then ends, so there is nothing to decide at the finish.
can you study for 45 minutes straight
Most people who have sat through a class can. The trick is one task for the whole 45, not three. If you drift at 30 minutes, drop to 30/10 for a week and come back.
