The short answer
For most screen work
- Every ~20 minutes: look at something far away for 20 seconds.
- Every ~30 minutes: a 30–60 second microbreak. Hands off, shoulders down, stand up.
- Every 50–60 minutes: 5–10 minutes away from the screen.
- Mid-day: a real lunch, not at the desk.
- After 2–3 hours of demanding work: a longer break of 15–30 minutes.
If you want those numbers laid out across your actual day, the break calculator does it in about ten seconds: enter your start and finish time, pick a rhythm, and it builds the schedule. The rest of this article is about choosing the right rhythm, and why the one you pick matters less than whether you follow it.
What the guidance actually says
There's no law of nature that says 52 minutes, or 25, or 90. What there is, is a consistent direction across occupational guidance and research:
- Frequent beats long. The UK Health and Safety Executive's guidance on display screen work says short, frequent breaks are better than longer, infrequent ones, and gives 5–10 minutes every hour as better than 20 minutes every two hours. It also says breaks should involve getting away from the workstation, not just switching to another screen.
- Short breaks help, modestly. A 2022 meta-analysis of micro-breaks (breaks of ten minutes or less) found they reliably increased energy and reduced fatigue. The effect on performance was smaller and clearest for less demanding tasks. Longer breaks helped more when the work was draining.
- Eyes need their own schedule. Eye-care bodies such as the American Academy of Ophthalmology recommend the 20-20-20 rule for screen users: every 20 minutes, look at something 20 feet away for 20 seconds. That's much more often than your back or your brain needs a break.
So the honest answer to "how often?" has layers. Your eyes want a pause every twenty minutes, your body every half hour or so, and your attention every hour or two. A good schedule covers all three without turning your day into a series of interruptions. More on the research side in the science of rest breaks.
Break schedules by type of work
| Type of work | Rhythm to start with | Why |
|---|---|---|
| General desk and admin work | 50 / 10 or 60 / 10 | Matches the hourly guidance and fits around meetings on the hour. |
| Deep work: writing, coding, design | 60–90 min work, 15–20 min break | Long enough to get into a problem; the break has to be longer to actually recover. |
| Fragmented or dreaded tasks | 25 / 5, long break every 4 (Pomodoro) | Short blocks lower the cost of starting and stop small tasks sprawling. |
| Studying and revision | 25–50 min study, 5–10 min break | Attention on reading and memorising drops faster than on hands-on work. |
| Calls and meetings all day | 5 min between every call, a walk every 2 hours | Back-to-back calls remove the natural gaps; put them back deliberately. |
| Very long days (10+ hours) | 50 / 10 plus two 20–30 min breaks | Fatigue builds across the day; the second half needs more recovery, not less. |
Two cautions. First, the popular 90-minute block is usually justified with "ultradian rhythms", and the evidence for a 90-minute work cycle is weaker than it sounds. See is 90 minutes evidence-based? Second, the famous "52 minutes on, 17 off" figure came from a productivity app's usage data, not a controlled experiment. Both are fine rhythms. Neither is magic.
For developers specifically, a sustainable coding rhythm goes deeper; for students, study breaks that actually work. If you want longer uninterrupted stretches, focus blocks covers how to structure them without skipping recovery.
How long each break should be
Frequency and length trade off against each other, and different breaks do different jobs:
- Eye break, 20 seconds. Look out of a window or across the room. You don't need to stop working, just lift your gaze.
- Microbreak, 30–60 seconds. Take your hands off the keyboard, roll your shoulders, stand up. It interrupts static posture before it becomes strain. See microbreaks at work.
- Screen break, 5–10 minutes. Leave the desk. Refill water, walk to another room, look at something that isn't a screen. Scrolling on your phone doesn't count.
- Long break, 15–30 minutes. After a long stretch of demanding work. Go outside if you can.
- Lunch, 30+ minutes. Away from the desk. The break most people skip, and the one the afternoon depends on.
The content of a break matters as much as its length. Two minutes staring out of a window does more for your eyes than ten minutes on your phone. What actually counts as a break has the full breakdown.
Signs you need a break sooner
A schedule is a floor, not a ceiling. Take a break early when you notice:
- You've read the same paragraph or line of code three times.
- Your eyes feel dry or gritty, or text starts to blur slightly.
- Your shoulders have crept up, or your wrists ache.
- You're making small mistakes you'd normally catch.
- You feel irritable about something trivial.
The catch is that concentration hides these signals. The deeper you are in a task, the later you notice them, which is exactly why a fixed schedule helps. It interrupts you before you would have interrupted yourself.
Making the schedule stick
Almost nobody fails at breaks because they picked 50 minutes instead of 60. They fail because at minute 50 they're in the middle of something, the reminder is easy to dismiss, and "just ten more minutes" becomes an hour. Three things help:
- Decide in advance. Choose the rhythm in the morning, when stopping is easy to agree to, not at 15:40 when it isn't.
- Get a warning. A few minutes' notice lets you finish a sentence or save your work, so the break doesn't feel like an ambush.
- Make skipping harder than stopping. A notification costs one click to dismiss. A full-screen break that you'd need a password to end changes the default. That's the difference between a reminder and an enforcer.
Not sure which of those is your problem? The burnout test scores your work habits in two minutes and suggests a work limit, a break length and how firm the break should be.
Pick a rhythm. Let something else hold you to it.
StopBurnout counts your active work time, warns you before the limit, then covers every monitor for the break. Set it to 50/10, 60/10 or your own numbers, and choose how firmly it holds the line.
Frequently asked questions
How often should you take a break when working at a computer?
A good default is 5 to 10 minutes away from the screen every 50 to 60 minutes, a 20-second look into the distance every 20 minutes or so, and a proper lunch away from the desk. The UK Health and Safety Executive advises that short, frequent breaks are better than longer, less frequent ones.
Is it bad to work for 3 hours without a break?
It is a common habit, but it is the pattern most guidance warns against. Three hours in one position with your eyes focused at one distance builds up eye strain and stiffness, and it leaves no point at which you notice fatigue before it affects your work. Break it up with at least one or two short breaks away from the screen.
How long should a break be?
For hourly screen breaks, 5 to 10 minutes is enough if you actually leave the screen. After long, demanding work, a longer break of 15 to 30 minutes helps more. Eye breaks can be as short as 20 seconds, and microbreaks for your hands and shoulders 30 to 60 seconds.
Is the 52/17 rule better than Pomodoro?
Neither is proven to be the best. The 52/17 figure came from an analysis of productivity-app data, not from a controlled study, and Pomodoro's 25 minutes is a convention rather than a finding. What the evidence supports is regular breaks of some kind. Choose the rhythm you will follow and adjust after a week.
What if my work doesn't allow breaks every hour?
Use changes of task as partial breaks: stand for calls, walk to talk to a colleague instead of messaging, and take the eye breaks that cost nothing. Then protect whichever longer breaks you can, especially one in the middle of the afternoon.
