How Much Screen Time Is Right by Age?
The American Academy of Pediatrics does not set one number for every child. The guidance shifts sharply with development: avoid solo screens before 18 months (live video chat is fine), keep it to about 30 minutes of high-quality, co-viewed content from 18 to 24 months, cap it near 1 hour a day from ages 2 to 5, and set consistent limits for school-age kids, with roughly 2 hours of recreational screen time a common ceiling for 6 to 12 year olds. Teens get a slightly higher 2.5-hour working guideline because so much homework and social life now lives on a screen. This calculator picks the right band for your child\'s age, then shows you exactly how far today landed over or under it.
How Content Type Changes the Limit
Not all screen minutes are equal. Co-viewed educational content builds vocabulary and problem-solving, while passive entertainment is the kind most strongly linked to sleep and attention trade-offs. We scale the base age limit by the content mix you choose.
Daily Limit = AgeBaseLimit x ContentFactor (educational 1.5, mixed 1.0, entertainment 0.7)So an 8-year-old has a 120-minute base. Flag the day as mostly educational and the ceiling rises to about 180 minutes; flag it as mostly games and streaming and it drops to roughly 84 minutes. The point is not to police every minute but to weight the easy wins toward content that actually teaches something.
Why the Recommendation Drops to Zero for Infants
Before about 18 months, babies learn language and cause-and-effect almost entirely from back-and-forth interaction with real people. Screens cannot supply that, and heavy early exposure is tied to slower language gains, which is why the recommended limit at this age is effectively nothing beyond a video call with grandparents.
