You want a number. Something specific you can hold up at 5pm, when the tablet has been on since school and you honestly cannot tell whether today was fine or not.
The numbers exist and they are in a table further down this page, so you can stop reading after it if that is all you came for. They come from the American Academy of Pediatrics, and they are firmer for toddlers than for anyone else.
Then the harder part. The AAP itself walked away from a single blanket hour count, and for children over five there is no official number at all. That was not a softening. It was an admission that "hours" turned out to be a poor way to predict whether a child is doing okay.
Nothing here is going to tell you that yesterday was a disaster. Most families land somewhere reasonable once they know which question to ask.
Short answer
● Under 18 months: no screen media other than video chat with a real person.
● 18 to 24 months: only alongside you, never handed over solo.
● Ages 2 to 5: about 1 hour of non-educational screen use on weekdays, up to 3 hours on weekend days.
● Ages 6 and up: no official hour figure. The AAP asks for consistent limits that protect sleep, physical activity, schoolwork and time with people.
● Use the displacement test instead of a stopwatch: what is the screen pushing out of the day?
● Who is in the room changes the calculation more than the clock does.

How much screen time for kids by age: the chart

Age |
What the guidance says |
Why |
What actually matters at this age |
|
Under 18 months |
Avoid screen media other than video chat |
Babies learn language and social cues from faces that respond to them. A screen cannot answer back |
Your own phone use, honestly. Background TV and a parent scrolling both cut into the back-and-forth talk that does the work here |
|
18 to 24 months |
If you introduce screens, watch together. No solo viewing |
Toddlers struggle to transfer what they see on a screen into real life unless an adult narrates the bridge |
Whether you are watching with them, not what they are watching |
|
2 to 5 years |
About 1 hour on weekdays, up to 3 on weekend days, of non-educational use |
Preschool days are short and the day fills up fast. Sleep and movement lose first |
The Physical Activity Guidelines want preschoolers active throughout the day, not in one block. Naps and bedtime are the tripwire |
|
6 to 10 years |
No hour figure. Consistent limits that protect sleep, activity, school and meals |
Screens now carry homework, school and friendships. A single number cannot cover all three |
60 minutes of moderate-to-vigorous activity a day, and 9 to 12 hours of sleep. Content and co-play matter more than duration |
|
11 to 13 years |
Same, plus explicit rules about where devices sleep |
Social media arrives here for many kids and it runs on a different reward schedule than TV did |
Where the phone charges overnight. Bedrooms are where the hours quietly triple |
|
14 to 18 years |
Same, negotiated rather than imposed |
Countdown timers at a sixteen-year-old cost more than they buy |
Sleep of 8 to 10 hours, per the American Academy of Sleep Medicine, and whether anything else in their week has survived |
Two footnotes on the 2 to 5 band, because they change the arithmetic a lot. The hour refers to non-educational use, so a video call with a grandparent is not in that budget. And it is an average across a week rather than a daily allowance you either hit or blow.

Why the AAP stopped giving a single number
The old rule was easy to remember: nothing under two, two hours a day after that. It was written when a screen meant a television in the living room, and it stopped describing reality somewhere around the time homework moved onto a laptop.
Three things broke it.
A screen stopped being one thing. Two hours of video chat with cousins, two hours of an algorithmic feed and two hours of building something in a game are the same number and nothing like the same experience. A limit that treats them identically gives a parent no useful information.
School moved onto the device. Once a district issues Chromebooks, a two-hour cap is arithmetic that cannot work.
Hours turned out to be a weak predictor. What separates good outcomes from bad ones is what the screen displaced and whether an adult was involved. Duration correlates with those things, so it looks important, but it is mostly standing in for them.
So the AAP replaced the cap with a Family Media Plan: household rules set per child and per situation, covering when devices are off, where they sleep, and what has to happen first.
That is genuinely less satisfying. A number is something you can enforce at the doorway on a Tuesday, and "make a plan" is not. Which is why the rest of this page is a plan you can actually run.
A better test than counting hours
Ask what the screen is displacing. Five things, in order of how much they matter, and every one of them is observable without an app.
Sleep. The American Academy of Sleep Medicine puts 6 to 12 year olds at 9 to 12 hours and teenagers at 8 to 10. Work backwards from wake-up time. If your ten-year-old is up at 6:45, lights out at 8:30 is not strict, it is the low end. Worth knowing: arousal and a bedtime pushed later do more damage than blue light does, which is the full mechanics of screen time and kids' sleep in one sentence.
Physical activity. The WHO and the US Physical Activity Guidelines both ask for 60 minutes a day of moderate-to-vigorous activity for ages 6 to 17, with muscle- and bone-strengthening on three of those days. The CDC has reported only about one in four US children hits it. If the 60 minutes are happening, screen hours are a much smaller worry. If nothing in the day raises a heart rate, that is the deficit to attack, and indoor activities that burn kids' energy will move the needle faster than shaving thirty minutes off YouTube.
Schoolwork. Not grades. Whether homework gets started without a two-hour standoff.
Face-to-face time. Any unstructured time today with another human, sibling, neighbor or friend, where nobody was on a device.
Meals. One meal a day at a table with no screens on it, including yours.
If all five are intact, the hour count is close to irrelevant. If one is being eaten, you have found your target, and it is a much smaller and more winnable fight than "less screen time."
Not every screen hour weighs the same
Rough ladder, best at the top:
1. Video chat with a person who answers back. Barely counts as screen time at any age.
2. Creating something: drawing, building, editing, coding.
3. Playing or watching alongside an adult, with talking.
4. Whole-body active play that gets the child off the sofa.
5. A solo game with rounds, levels and an ending.
6. Chosen episodic video. Finite, and it stops.
7. Algorithmic infinite feeds. No ending exists by design, which is why "one more video" behaves so badly.
The distance between the top and the bottom of that ladder is larger than the distance between one hour and three. We went through where the line actually falls in active vs passive screen time.
One caveat to state plainly: an active screen is still a screen. Moving your body while looking at a TV is better than sitting still while looking at a TV, and it is not the same as going outside.

Why co-viewing changes the calculation
The AAP singles out co-viewing and co-playing as the biggest single factor separating screen time that helps from screen time that does not. Adult in the room, talking, asking, connecting what is on screen to something real.
You do not have to do all of it, which is the part that gets lost. Realistically:
● Five minutes at the start of a show, then leave.
● One question afterwards. "What was the sneaky bit?" beats "did you enjoy it."
● For a school-age child, one round of their game a week. Let them beat you, which they will.
● For a teenager, ask what they are watching and then actually watch four minutes of it.
A solo hour and a shared hour are the same number on a screen-time report and different events in a child's week.
How to count when school runs on a Chromebook
Stop counting one number. Use three buckets and only police the third.
Required. School, homework, assigned reading apps, video calls with relatives. This is not discretionary and it does not belong in a limit.
Chosen and active. Creating, building, movement games, playing something with another person in the room.
Chosen and passive. Feeds, autoplay, background video watched alone. This is the bucket almost every screen-time worry is actually about, and it is usually far smaller than the scary total.
Three moves that work with a school-issued device: ask the teacher what is genuinely required, because it is often less than the child claims. Keep the device on a table rather than a bed. Build in a movement break every 45 minutes, since a static six-hour school day is an activity problem before it is a screen problem.
Run a one-week audit instead of a stopwatch
For seven days, write one line a day. Not hours. Just: did they sleep enough, did they move for an hour, did they eat with someone, and what got skipped.
By day five the pattern is obvious, and it is almost never "too many hours" in general. It is usually one specific hour, in one specific place, most often after dinner or in a bedroom.
