For young children the World Health Organization recommends no screen time under the age of 2, and no more than one hour a day for ages 2 to 4, with less being better. For older children and teens there is no single magic number: the American Academy of Pediatrics (AAP) recommends consistent limits that fit your family rather than a fixed figure. These numbers are about leisure time, not schoolwork.
But a number is only half the story. Just as important is what your child does on the screen, when, and whether there is enough time left to move, sleep and be together. In this article you'll find the guidelines by age, plus how to make them workable at home without a daily argument.
The guidelines by age in one table
The table below summarizes the WHO and AAP guidance. See it as a handle, not a strict standard your child has to hit exactly every day.
| Age | Leisure screen time | Source |
|---|---|---|
| Under 1 | Not recommended | WHO |
| 1–2 years | Not recommended for 1-year-olds; max 1 hour at age 2 | WHO |
| 3–4 years | No more than 1 hour, less is better | WHO |
| 6+ years (primary and secondary) | Consistent limits that fit your family | AAP |
Important: these limits are about leisure screen time. Work for school or a task (on Smartschool, a laptop, a presentation, research) does not count here.
Why movement comes before screen time
The healthiest way to look at screen time is to start from the other end: not "how much screen is allowed," but "is there enough room for the rest?" The WHO stresses "replacing prolonged restrained or sedentary screen time with more active play," while making sure children get "enough good-quality sleep."
Long sitting is not bad in itself, but it becomes a problem when it happens too often and too long. So break up long stretches of sitting with a short active break, and for under-5s, children should not be restrained (in a pram or high chair) for more than an hour at a time. When your child does sit, a screen-free activity now and then helps: reading, drawing or a puzzle.
Quality counts as much as the clock
Two hours watching a nature documentary together and talking about it is something very different from two hours scrolling clips alone. The clock doesn't say everything. It's worth looking at three things at once: the time, the content and the company.
The AAP advises parents to "choose quality content": use only apps and shows that "teach, inspire creativity and encourage social connection," and avoid content with lots of ads or violent or age-inappropriate material. A few simple rules help: "one screen at a time," and turn off autoplay and notifications, which are "designed to keep kids engaged longer." That way watching becomes a choice instead of an endless stream.
Screen-free moments and zones
You don't have to capture everything in minutes. Often it's easier to keep fixed moments and places screen-free. The AAP names three "screen-free zones" that make a difference:
- At the dinner table. No screens during meals, so there's room to talk.
- During homework. One task at a time, with no distraction from notifications.
- Before bed. Keeping screens out of the bedroom protects sleep.
That last point is crucial. A screen right before bedtime makes falling asleep harder, which matters because good sleep underpins learning and mood. Keep devices out of the bedroom at night.
Set the example yourself
Children don't only look at their own screen; they look at yours too. The AAP points out that parents are "an important role model in practicing healthy digital habits," and advises making a plan "for every member of your family, including yourself." Putting your phone away at the table says more than ten reminders to "put that away."
That doesn't mean you have to be perfect. It does mean the rules apply to the whole family, parents included. A family that builds in screen-free moments together has far fewer one-off arguments.
How do you notice it's becoming too much?
Not every child reacts the same way to the same amount of screen time. Instead of only watching the clock, also watch for signals in daily life. They often say more than the exact number of minutes.
Pay attention if screen time structurally comes at the cost of other things:
- your child clearly moves less or no longer likes going outside;
- falling asleep is harder, or they sleep less;
- homework and chores are left undone;
- stopping watching or playing almost always ends in conflict;
- plans with friends and hobbies fade into the background.
If you recognize a few of these signals, it's no reason to panic, but it is a good moment to review the agreements together. Often it's enough to adjust the balance between screen time, movement and sleep a little.
From guideline to a rule that works
The biggest pitfall is having to police the limit every single day. "Five more minutes" becomes ten, ten becomes a fight. What really helps is making clear agreements once and keeping them the same on every device: computer, phone and tablet.
Three principles make the difference:
- Consistent. The same rule every day and on every device. The rule becomes predictable and your child doesn't have to negotiate each time.
- Beforehand, not after. A warning that time is almost up works better than suddenly taking the screen away. Your child can wind down calmly.
- Earned, not given. Tie game time to other habits, such as homework or reading first. Screen time then becomes a reward instead of a right.
How to set this out concretely for your family, you'll read in making family screen-time rules. And if stopping gaming always ends in a fight, read when your child won't stop gaming.
Frequently asked questions
How much screen time is healthy per day?
The WHO recommends no screen time for children under 2 (screen time is not recommended), and no more than 1 hour a day for ages 2 to 4, with less being better. For older children there is no single magic number: the AAP recommends consistent limits that fit your family, set in a media plan.
Does homework on a screen count as screen time?
The guidelines are about leisure screen time. Schoolwork on a laptop or on Smartschool does not count toward it. It still helps to build in short breaks and to interrupt long stretches of sitting during schoolwork too.
Is one hour over the guideline immediately harmful?
No. A limit is a guideline, not an alarm. What matters more than one day is the pattern across the week: enough movement, enough sleep and screen-free moments. A bit longer at the weekend is fine if the balance is right.
What matters more: how long or what my child watches?
Both. Beyond time, what your child does and with whom makes a real difference. The AAP advises choosing quality content and watching together where you can; that weighs as much as the clock.
How Atlas helps
The hardest part of screen time isn't knowing the limit, but applying it consistently day after day, on every device and without a fight. Atlas lets you set your own rules once, after which they work on computer, phone and tablet at the same time. Your child sees how much game time is left, and when it runs out the timed apps close by themselves while school and allowed apps keep working. You can also tie game time to the "learning first" rule, and every Sunday you get a summary of learning and screen time. That turns screen time into a clear agreement instead of a daily discussion.
