Recommended Screen Time by Age: Limits, Guidelines and Reality

There are two different questions hiding inside "how much screen time is recommended for my age". For children, there is published guidance with actual numbers in it. For teenagers and adults, there is no official limit at all — the advice switches from hours to habits. This page covers both: the age-by-age table people are looking for, and the honest explanation of where the numbers stop and judgement starts.

Screen time limits for kids by age

The widely cited paediatric guidance — the American Academy of Pediatrics in the US and the World Health Organization internationally — covers the early years in detail and then deliberately goes vague. The table below summarises the commonly quoted version. It refers to recreational screen use, not schoolwork.

Notice the shape of it. The guidance is strict where the evidence is strongest — the first five years — and then hands the decision back to you. That is not a gap in the research so much as an admission that two hours of video calls with family and two hours of autoplay at midnight are not the same two hours.

Why the hourly limits stop after primary school

By the time a child is eleven or twelve, screens stop being one activity and become the container for most activities: homework, friendship, music, navigation, money. Counting the hours measures the container instead of what is in it. Every serious set of guidance from that age onward asks the same four questions instead of counting.

• Is sleep protected? Late-night use is the single most consistent harm across every age group studied.
• Is the day still moving? Physical activity is the thing screen time most often quietly replaces.
• Is it social or solitary? Messaging friends and doomscrolling strangers score very differently on wellbeing measures.
• Can it stop? Being able to put the device down on request matters more than the total on the report.

Appropriate screen time by age: what to actually enforce

Toddlers and preschoolers (2-5)

The hour limit is the easy part. The part that matters is co-viewing: sitting with them and talking about what is on the screen turns passive watching into language practice. One hour watched together beats thirty minutes watched alone in another room.

Primary school (6-12)

This is the age where a family rule works best, because it is the last age where you can genuinely enforce one. Two rules do most of the work: devices out of bedrooms overnight, and screens after the other things, not instead of them. Homework, outside, dinner, then whatever is left.

Teenagers (13-18)

Blanket limits tend to backfire here, partly because a teenager's social life genuinely lives in those apps and partly because they will route around any rule you set. What survives is negotiating the edges rather than the middle: a charging spot outside the bedroom, phones down at meals, and an agreement about what the last hour of the night looks like.

Adults

Nobody is going to hand you a number, so the useful reference point is other people your age. Typical self-reported leisure screen time runs from around six and a half hours a day in your twenties down to about three hours by your seventies. If you are far above your bracket and your evenings feel like they vanish, that is a more meaningful signal than any recommended limit could be.

Screen time rules for kids that actually hold

1. 1Pick times, not totals. "No screens after 8pm" is enforceable in a way that "two hours a day" never is, because nobody has to keep score.
2. 2Name screen-free zones. Bedrooms and the dinner table cover most of the harm with two sentences of rule.
3. 3Make the end predictable. Ending on an episode boundary or a natural stopping point avoids most of the fights that limits create.
4. 4Follow the same rules yourself. Children calibrate to what adults do with their phones, not to what the family policy says.
5. 5Revisit it every few months. A rule that fitted a nine-year-old will be ignored by an eleven-year-old.

These are general summaries of publicly available guidance, not medical advice, and they are not tailored to any individual child. If you are worried about a child's sleep, development or mood, a GP or paediatrician is the right place to take it.

The one number worth watching at every age

If you strip all of this back to a single rule, it is the hour before bed. It is the screen time most consistently linked to worse sleep, it affects toddlers and adults alike, and it is the only limit on this page that costs nothing to try. Everything else on the list is an optimisation. That one is the load-bearing wall.
