Screen Time by Age: What the Evidence Says
NHS and WHO guidance translated into practical daily limits — with tips for every stage from toddler to teenager.
Why screen time guidance matters
Screen time is one of the most common concerns raised by parents, and for good reason. The research on excessive or poorly managed screen use is consistent: too much, too early, with the wrong content, at the wrong time of day can affect sleep, attention, language development, and physical activity. At the same time, screens are not inherently harmful — context, content quality, and co-viewing all matter as much as raw hours. The NHS and the World Health Organisation (WHO) have both published guidance that gives families a clear starting point, though both emphasise that quality of screen use matters at least as much as quantity.
Recommended screen time by age group
| Age group | NHS/WHO guidance | Practical notes |
|---|---|---|
| Under 2 years | Avoid screens entirely, except video calls with family | Babies learn through real-world interaction. Screens displace the face-to-face contact essential for early language and bonding. |
| 2–4 years | Maximum 1 hour per day of high-quality content | Watch together where possible. Choose educational programmes (CBeebies, BBC iPlayer). Avoid fast-paced, advert-heavy content. |
| 5–7 years | 1–2 hours with regular breaks; screens off 1 hour before bed | The 20-20-20 rule helps: every 20 minutes, look 20 feet away for 20 seconds. Devices out of bedrooms at night. |
| 8–10 years | Up to 2 hours of recreational screen time | Educational use (homework, coding, reading) can sit outside this limit. Focus on ensuring physical activity and social time are not displaced. |
| 11–13 years | Negotiate limits together; aim for no more than 3 hours recreational use | Involve your child in setting rules — they are more likely to follow limits they helped create. Track social media time separately from passive viewing. |
| 14 years and over | Self-regulation with clear boundaries; protect sleep and mealtimes | Rather than strict hour limits, focus on sleep protection (phones charging outside bedrooms), mealtime rules, and open conversations about balanced use. |

The evidence behind the guidelines
The WHO guidelines for under-5s are grounded in research linking sedentary screen time with delayed language development and reduced physical activity. The RCPCH reviewed the evidence for older children in 2019 and took a deliberately nuanced position: rather than setting hard limits for teenagers, they advised focusing on whether screen use was negatively affecting sleep, physical activity, face-to-face interaction, or mental health. This reflects the reality that not all screen time is equivalent — a child video-calling a grandparent, creating digital art, or following an online tutorial is engaged in something qualitatively different from passively scrolling short-form video. The research on social media and mental health, particularly for girls aged 11–15, does show associations between heavy use and poorer wellbeing, but establishing causation remains complex.
Practical tips for managing screen time at home
The following approaches work across age groups and are consistently recommended by child development specialists:
- •Create screen-free zones and times. Mealtimes and bedrooms are the most important. Children who keep devices out of their bedrooms sleep significantly better.
- •Use built-in tools. Apple Screen Time, Google Family Link, and Android Digital Wellbeing all allow you to set daily limits per app category. These tools are free and built into most devices.
- •Model the behaviour you want. Children whose parents frequently use devices at the dinner table or during family time are more likely to do the same. This is one of the most powerful levers parents have.
- •Talk about content, not just time. Knowing what your child is watching and who they are interacting with matters more than the raw number of hours. Regular, non-judgmental check-ins are more effective than policing.
- •Protect sleep above everything else. Sleep deprivation from late-night device use has measurable effects on attention, mood, and academic performance. The NHS recommends screens off at least one hour before bedtime for all children.
When limits are difficult to enforce
Many parents find that setting limits in theory is easier than enforcing them in practice, particularly with teenagers. Conflict over screen time is common and normal. A few approaches that tend to work better than outright bans or constant battles: negotiate rules together and write them down as a family agreement; tie earned screen time to completion of other activities rather than imposing arbitrary cuts; use a gradual reduction approach rather than sudden removal; and focus conversation on how the device makes them feel rather than framing it as a behaviour problem. If screen use has become a significant source of conflict or you are concerned about dependency, your GP or school SENCO can be a useful first contact point.
