The 52/17 Rule: Work 52 Minutes, Break 17 (Free Timer)

The 52/17 rule is a work rhythm: 52 minutes of focused work, then a 17-minute break away from the screen, repeated through the day. It came from productivity-tracking data rather than a lab experiment, and it suits people who find 25-minute rounds too short. You can run it with the free focus timer by setting the focus length to 52 minutes and the breaks to 17.

Where the 52 17 rule comes from

The numbers come from DeskTime, a company that makes time-tracking software. In 2014 it looked at how its most productive users (the top 10% by its own measure) split their day, and found that on average they worked for about 52 minutes and then took about 17 minutes off, often away from the computer entirely. The finding spread widely through business news and productivity blogs.

Two things are worth knowing before you treat it as a law:

• It's an observation, not a test. It describes what the most productive users happened to do; it doesn't prove that switching to 52/17 will make anyone else more productive.
• The numbers moved. As per DeskTime, a later rerun of the analysis on 2021 data found its most productive users averaging around 112 minutes of work and 26 minutes of break.

So the useful lesson isn't the exact 52 and 17. It's the pattern underneath: long, genuinely focused stretches, followed by real breaks that are long enough to recover.

Why a long break helps

Seventeen minutes is a lot longer than the 5-minute break of the Pomodoro Technique, and that's the point. A 17-minute break gives you time to:

• Walk, stretch or get outside, rather than just glance at your phone.
• Eat something or make tea properly.
• Talk to someone, which resets attention better than scrolling.

The DeskTime write-up stressed that its top users tended to step away from the computer during breaks. A break spent reading email isn't really a break.

52/17 vs Pomodoro

	52/17	Pomodoro
Focus block	52 minutes	25 minutes
Short break	17 minutes	5 minutes
Long break	Not part of the rule	15-30 minutes after 4 rounds
Rounds in a 4-hour morning	About 3-4	About 7-8
Share of time spent focusing	About 75%	About 70-77% over a full cycle, depending on the long break
Best for	Writing, coding, design, revision of long topics	Getting started, dull tasks, low energy days

The two are closer than they look. Both alternate focus with a break; 52/17 just uses fewer, longer cycles. If you've never used a timer for work, our guide to the Pomodoro Technique is the easier place to start. Once 25 minutes starts to feel like it cuts you off mid-thought, try 52/17.

How to set up the 52/17 rule in the focus timer

The free focus timer starts with the classic 25/5 rhythm, but every length is adjustable:

1. Open the focus timer and click Settings.
2. Set Focus (min) to 52.
3. Set Short break (min) to 17.
4. The timer always includes a long break, so set Long break (min) to 17 as well (or to 30 if you want a longer rest at lunch time). Pick how many sessions come before it in Long break after.
5. Leave Start the next phase by itself ticked if you want the break to begin automatically, or untick it to start each phase yourself.
6. Press Start.

A chime plays when each phase ends, and the time left shows in the browser tab title, so you can work in another tab and still see it. The squares under the clock fill in as you complete sessions. Use Skip to end a phase early and Pause if you're interrupted. Each length can be anything from 1 to 180 minutes, so you can also try the 112/26 rhythm from the later data.

If you'd rather log how long you actually stay focused before you pick a rhythm, run the free online stopwatch for a few work sessions and press Lap whenever your attention drifts.

Making it work in a real day

• Plan the blocks. Three or four 52-minute blocks fit a morning. Decide what each one is for before you start. Time blocking is a good way to lay out the day around them.
• Protect the 52 minutes. Notifications off, phone in another room, one task only.
• Use all 17 minutes. If you come back after 5, the rhythm turns into "52 and a bit". Move, drink water, look at something far away.
• Adjust honestly. If you fade at 35 minutes, shorten the focus block. If 52 minutes regularly ends mid-flow, try longer. The best rhythm is the one you'll keep.
• Students: 52 minutes is close to a typical lesson, which makes it a natural fit for revision. See our focus tips for studying for more.

Start a 52-minute block

Open the free focus timer, set 52 and 17 in Settings, and press Start. It runs in your browser with no sign-up, and nothing is sent anywhere. Keep the tab open and the chime will tell you when to stop.
