How much screen time is too much? An age-by-age guide
What pediatric and health guidance says about screen time for babies, toddlers, school-age children and teens, and how to turn it into limits that work.

"How much screen time is too much?" is the question most parents ask, and the honest answer depends on the child's age and what the screen is replacing. Health organizations give clearer numbers for very young children and shift to principles as children grow. This guide summarises the general direction of that guidance. It is not medical advice, and your pediatrician knows your child best.
The short version
| Age | General guidance | What matters most |
|---|---|---|
| Under 18 months | Avoid screens except video calls | Talking, play and touch with caregivers |
| 18 to 24 months | If used, choose high-quality content and watch together | Shared use, short sessions |
| 2 to 5 years | About one hour a day of high-quality programming is a common recommendation | Co-viewing, no screens at meals or before sleep |
| 6 to 12 years | Consistent limits that protect sleep, activity and homework | A written family plan, screen-free zones |
| 13 to 17 years | Fewer hard numbers, more shared agreements | Sleep, mood, focus, boundaries online |
The World Health Organization recommends no sedentary screen time for babies under one and no more than one hour a day for children aged two to four, with less being better. The American Academy of Pediatrics suggests avoiding screens for toddlers under 18 months except for video chatting and encourages parents of older children to build a family media plan.
Babies and toddlers
For the youngest children, the main concern is what screens replace. Face-to-face talk, floor play and sleep drive early development, and a screen cannot respond to a baby the way a person does. If you do use screens, choose slow, simple content and sit with your child to talk about what you see.
Preschoolers (2 to 5)
Quality and company matter. A short, well-made show watched together and discussed is a different experience from an hour of autoplay alone. Switch off autoplay, avoid screens during meals and for the hour before bed, and keep devices out of the bedroom.
School age (6 to 12)
At this stage children get homework on devices, play online with friends and want their own phone. A single daily number is less useful than a few firm anchors:
- Sleep comes first: no screens in bedrooms overnight
- Homework, movement and family time happen before leisure screens
- Weekends can be more flexible than school days, with a clear end
Many families land on a modest daily limit on school days and a longer limit on weekends, and revisit it every few months.
Teens (13 to 17)
Teenagers need autonomy, and rigid caps often backfire. Focus on the outcomes you actually care about: enough sleep, time offline, healthy mood, and safe behaviour online. Agree on rules together, explain your reasons, and let some boundaries loosen as trust grows.
Signs that screen time is crowding out something important
- Your child is regularly tired, irritable or sleeping less
- Interest in friends, sport or hobbies is dropping
- Homework slides or mornings become a struggle
- Your child gets very upset when a screen is taken away and cannot recover
If you see several of these over weeks, consider a calm conversation, a lower limit, and a word with your pediatrician or school.
Turning guidance into limits
Start with the biggest lever, which is sleep, and set a bedtime lock before any daily number. Then add a limit that fits your family's routine, make it visible to your child, and review it together. A tool like Tinyclock can enforce the agreement, but the agreement is the important part. See screen time routines that reduce arguments for a step-by-step approach.

Frequently asked questions
Is there one right number of hours for every child?
No. Guidance for older children focuses less on a fixed number and more on whether screens crowd out sleep, movement, homework, play and family time.
Does educational screen time count the same as entertainment?
Content and context matter. Time spent video chatting with grandparents or creating something is different from passively scrolling, though both can still add up.
