Most child development folks suggest keeping it under 2 hours on school nights, though the exact limit depends on what they're doing - homework on a screen hits different than scrolling. The bigger thing is making sure it doesn't cut into sleep, exercise, or homework time.

The hard part isn't the number - it's whether they're actually winding down before bed, because a 13-year-old glued to their phone at 10pm messes with sleep way more than two focused hours earlier in the day.

Fixating on a specific hour count misses the point entirely. What actually matters is whether the kid has decent sleep, can focus on schoolwork, and isn't neglecting everything else in their life. Some 13-year-olds can handle three hours of genuinely useful screen time without issues; others spiral after one hour of mindless content. The quality and timing matter way more than the raw number.

That said, there's a practical thing most people don't talk about: separating work screens from leisure screens. If your teen needs a laptop for homework, that's one conversation. If they're then switching to TikTok or gaming on the same device, your brain loses track of what counts. One useful move is having a physical cutoff point - like all devices out of the bedroom by 9pm, full stop - rather than trying to police minutes. It removes the constant negotiation and actually helps sleep quality, which spins off into better mood and school performance.

The real test is whether they're sleeping well, keeping up with homework, and still seeing friends in person. If those three things are solid, the screen time is probably fine. If school's slipping or they're wired at 11pm, you've got your answer regardless of what some guideline says.

the trick that actually works is treating it like fuel rather than a reward - let them use screens for something specific (homework, a hobby, connecting with friends) and then it's done, instead of leaving it open-ended as entertainment they can graze on all evening. in our house, we found that once the laptop closes after homework, phones go to a charging station in the kitchen around 8pm on school nights, and that simple structure eliminated the midnight scrolling problem way better than any lecture about "two hours" ever did.
