There is no single number that works for everyone, but experts do agree on clear guidelines by age. For children under two, screen time should be avoided outside of video calls. For children aged two to five, one hour per day is the recommended maximum. School-age children and teenagers can handle more, but the quality of what they are watching matters just as much as the quantity. For adults, the question is less about strict limits and more about awareness: most people significantly underestimate how much time they spend on their screens each day.

This guide breaks down what healthy screen time actually looks like across every age group, what the research says, and what practical steps you can take to find a better balance.

What the Guidelines Say by Age Group

Health organisations including the World Health Organisation and the American Academy of Pediatrics have published screen time recommendations that are widely referenced by paediatricians and family therapists. Here is what they say.

Under 2 years

Screens should be avoided as much as possible for children under two. The exception is video calling, which involves real human interaction and is considered developmentally appropriate. Some organisations, including the American Academy of Pediatrics, allow for high-quality content from 18 months onward, provided a caregiver watches alongside the child and engages with what is on screen. Passive screen exposure at this age, even in the background, has been linked to delays in language development.

Ages 2 to 5

One hour of high-quality content per day is the recommended ceiling. The emphasis on quality matters here. Educational programmes watched together with a parent or caregiver, with conversation around what is happening on screen, produce very different outcomes than a child watching unsupervised entertainment for the same duration.

Ages 6 to 12

There is no fixed hour limit for this group, but guidelines consistently recommend:

• Setting consistent daily boundaries rather than leaving it open-ended

• Ensuring screens do not replace physical activity, sleep, or face-to-face time

• Prioritising content that is interactive, educational, or creative over passive consumption

• Keeping screens out of bedrooms, especially after a set evening time

Teenagers (13 to 18)

Teenagers present the most complex picture. Their screen time is often tied to schoolwork, social connection, and increasingly to part-time work, which makes blanket limits harder to apply. Research does consistently show that social media use above two hours per day is correlated with poorer sleep quality and higher rates of anxiety, particularly in teenage girls. The conversation with teenagers is less about hard limits and more about helping them develop their own awareness of how different types of screen use make them feel.

Adults

The average adult in Belgium spends more than six hours per day looking at a screen, combining work, entertainment, and social media. Most of that feels invisible because it happens in short bursts throughout the day. For adults, the most useful question is not "how many hours" but "which hours." Screen use in the hour before sleep, for example, consistently disrupts sleep quality regardless of total daily use.

Why Screen Time Conversations Are Often Too Focused on the Number

The biggest limitation of the "X hours per day" framework is that it treats all screen time as equivalent. Forty-five minutes of a video call with grandparents is not the same as forty-five minutes of autoplay content. An hour of coding practice is not the same as an hour of scrolling. The guidelines are a useful starting point, but the more important habit to build is checking in with how screen time is being spent, not just how much of it there is.

Researchers increasingly use the term "screen quality" alongside "screen quantity" to make this distinction. Screens used for active engagement, creativity, learning, or real communication tend to produce neutral or positive outcomes. Screens used for passive consumption, particularly of algorithmically curated short-form content, are where the negative associations cluster.

Practical Ways to Set Better Limits

Getting from awareness to action is where most families and individuals get stuck. A few approaches that consistently show up in research as effective:

• Set a family screen schedule rather than negotiating every evening. Predictable boundaries are easier to maintain than case-by-case decisions.

• Use device-level tools to set app time limits. Both iOS and Android have built-in screen time management features that require no third-party apps.

• Create screen-free zones at home, starting with the bedroom and the dinner table. The physical separation matters more than most people expect.

• Model the behaviour you want. Children's screen habits are strongly correlated with their parents' screen habits. Rules that apply only to children rarely stick long-term.

• Talk about it rather than just enforcing it. Children and teenagers who understand why limits exist are significantly more likely to internalise them over time.

The Connectivity Layer Most People Overlook

Device settings and household rules are important, but they operate on the device itself. What sits underneath every smartphone and tablet is a mobile connection, and the plan providing that connection is a layer of control most families have not thought about.

Traditional telecom contracts in Belgium tend to lock families into rigid plans with little flexibility to adjust data allowances or respond quickly to changing needs. A child getting their first phone does not need the same plan as a working adult, and the plan design should reflect that.

Firsty is a global eSIM app built on a simple belief: connectivity is a right, not a privilege. That means offering a genuinely free entry point to mobile data, so a child's first connection does not have to come with a bill attached. For families thinking about how to manage their child's mobile use without locking into an expensive contract, it is worth exploring what Firsty already offers at firsty.app.

Summary

The habits that make the biggest difference are the ones built into your environment and your routine, not the ones that require willpower every day.

FAQ

1. What is a healthy amount of screen time per day?

   • It depends on age. Children under two should avoid screens except for video calls, with some organisations allowing high-quality content from 18 months with a caregiver present. Children aged two to five should have a maximum of one hour per day. For older children and adults, there is no universally agreed limit, but experts recommend prioritising screen quality over quantity and protecting sleep by avoiding screens in the hour before bed.

2. How much screen time is too much for a child?

   • Any screen time that regularly replaces sleep, physical activity, homework, or face-to-face interaction is too much, regardless of the total hours. For children aged two to five, more than one hour per day is the threshold most health organisations use. For school-age children, the quality and context of screen use matters as much as the amount.

3. What is the average screen time per day in Belgium?

   • Belgian adults average more than six hours of screen time per day across devices, with recent figures placing the daily average at around six and a half hours. This includes work screens, entertainment, and social media. Teenagers typically average between five and seven hours, with social media accounting for a significant portion of that total.

4. Is all screen time equally harmful?

   • No. Research consistently distinguishes between active and passive screen use. Video calls, educational content, creative tools, and interactive learning are associated with neutral or positive outcomes. Passive consumption of algorithmically curated short-form content, particularly social media feeds, is where negative associations with sleep, attention, and mental health are most consistently found.

5. What is the best way to reduce screen time for children?

   • The most effective approaches combine environmental design (screen-free zones, device charging outside the bedroom), predictable schedules rather than daily negotiations, device-level tools for setting app time limits, and modelling the behaviour you want to see. Children whose parents also limit their own screen use are significantly more likely to develop healthy habits themselves.

6. Does the mobile plan affect screen time management?

   • Device-level controls like iOS Screen Time or Android Digital Wellbeing are the primary tools most families use. However, the mobile plan providing the underlying connection is also a layer worth considering, particularly for flexibility, data control, and how easily a plan can be adjusted as a child's needs change. A genuinely free entry-level option, like what Firsty offers, removes the financial barrier entirely.
