The Pomodoro Technique: Rules, Origins and How to Use It

The Pomodoro technique is a time-management method: work on one task for 25 minutes, take a short break of 3 to 5 minutes, and after every four rounds take a longer break of 15 to 30 minutes. Each 25-minute block is called a pomodoro, Italian for tomato.

The method was created by Francesco Cirillo, and it is simple enough to start with nothing more than a kitchen timer. This guide covers where it came from, the original rules, what a full set looks like on the clock, common variations, and how to run it with our free Pomodoro timer, which cycles through the focus blocks and breaks for you.

Where the Pomodoro technique comes from

In his own description of the method, Cirillo writes that the idea came to him in the late 1980s, during his first years at university, when he was struggling to concentrate. He set himself a small challenge, to study properly for just 10 minutes, and used a kitchen timer shaped like a tomato to keep himself honest. That timer gave the method its name.

His paper presents the technique as he defined it in 1992, and he later taught it to individuals and teams. The official Pomodoro Technique site describes it as a complete productivity system, not just a timer, with daily planning, interruption management and effort estimation built in. “Pomodoro” is a registered trademark associated with Cirillo’s method.

The basic rules

1. Choose a task and write it down. Cirillo’s version starts the day with a “To Do Today” list.
2. Set the timer for 25 minutes and work only on that task until it rings.
3. Mark the pomodoro as done. In the original method you put an X next to the task for each completed block.
4. Take a short break of 3 to 5 minutes. Step away from the work completely.
5. After every four pomodoros, take a longer break of 15 to 30 minutes.

Two rules make the method stricter than “work in 25-minute chunks”. First, a pomodoro is indivisible: there’s no half or quarter pomodoro. Second, if a pomodoro is definitively interrupted, it doesn’t count, and you start a fresh one. If you finish the task early, Cirillo suggests using the remaining minutes to review or improve what you’ve done rather than stopping the clock.

What a full set looks like

Here is one set of four pomodoros started at 9:00 a.m., with 5-minute short breaks and a 15-minute long break:

That’s 100 minutes of focused work in 2 hours 10 minutes. A working day with three sets gives 12 pomodoros, or 5 hours of focused time. If you log your time for a client or a timesheet, six pomodoros are 150 minutes, which is 2.5 hours; our minutes to decimal hours chart helps with the odd amounts.

Handling interruptions

Cirillo splits interruptions into two kinds.

• Internal interruptions are your own urges to check email, look something up or start a different task. Write the thought down on your list and go straight back to the pomodoro. You’ll deal with it in a later block.
• External interruptions come from other people. His strategy is to inform the person that you’re busy, negotiate a time to get back to them (often “in 25 minutes”), and call them back as agreed.

If something truly can’t wait, stop, and treat that pomodoro as void. Keeping a tally of interruptions on your list shows you, over a few days, where your focus actually goes.

Common variations

Many people keep the rhythm but change the numbers. None of these is part of the original method, but they follow the same idea of fixed focus blocks and planned rest:

• 50/10: 50 minutes of focus and a 10-minute break, so each cycle takes an hour. Useful for work that takes a while to get into.
• Shorter blocks: 15 or 20 minutes when a task is hard to start, or for younger students.
• Fewer rounds per set: two or three pomodoros before a long break, to fit around meetings.
• Single blocks: one pomodoro to get started on a task you’ve been avoiding, with no plan to do a full set.

If you change the lengths, keep them the same for a few days so you can compare how much you get done.

How to run it with our timer

The Pomodoro timer starts with the classic settings: 25-minute focus blocks, 5-minute short breaks, a 15-minute long break and four rounds per set. You can change each one: focus from 1 to 120 minutes, short and long breaks from 1 to 60 minutes, and 1 to 8 rounds per set.

• The screen shows the current phase and round, such as “Focus 1 of 4”.
• A chime marks each change: a bell when focus starts and a softer chime when a break starts.
• The next phase starts automatically, or you can turn that off and press Start yourself.
• After the last round, the long break ends the set and your chosen sound plays.

Prefer separate timers? Use the 25 minute timer for each pomodoro and the 5 minute timer for breaks, or the online timer for any other length.

Frequently asked questions

How long is a pomodoro?

25 minutes of work. In Cirillo’s description, each one is followed by a 3 to 5 minute break, which is why a pomodoro is sometimes counted as a 30-minute unit including the break.

How long is the long break in the Pomodoro technique?

15 to 30 minutes, taken after every four pomodoros. Our timer uses 15 minutes by default, and you can change it.

Who invented the Pomodoro technique?

Francesco Cirillo. He started using the method as a university student in the late 1980s, timing himself with a tomato-shaped kitchen timer.

What do you do if a pomodoro is interrupted?

If the interruption can be postponed, note it and carry on. If you have to stop, that pomodoro doesn’t count: deal with the interruption and start a new 25-minute block.

Can I change the 25-minute length?

Yes. Many people use longer blocks, such as 50 minutes, or shorter ones. The original method uses 25 minutes, but our Pomodoro timer lets you set any focus length from 1 to 120 minutes.
