TikTok vs Instagram vs Snapchat: what Pew’s new study actually found
Pew Research Centre published a large new study on 15 April 2026 based on 1,458 US teenagers aged 13 to 17, and it’s the clearest platform-by-platform comparison of teen social media use available right now. The headline figure is specific enough to bring to a conversation this week: 37% of teen TikTok users say the app hurts their sleep. Not “might affect” — teenagers saying it themselves.
Each platform has a different job in a teenager’s life
That’s the thing the Pew study makes clearer than most. These aren’t interchangeable apps that teenagers happen to use — they serve different purposes, which means the risks and the conversations are different too.
Snapchat is where teens post most frequently. It’s primarily a messaging and content-sharing platform — volume and social connections matter more than time spent. Instagram functions more like a digital portfolio, the place teenagers curate how they appear to the world. The relevant questions there are around self-presentation and comparison: what are they posting, who’s the audience, how much energy goes into managing that image. TikTok dominates for passive consumption — watching and scrolling for long stretches — which is exactly why sleep is the right thing to focus on.
The gap between what parents think and what teenagers say
44% of parents believe their teenager spends too much time on TikTok. Only 28% of teens agree. That 16-point gap isn’t evidence that parents are wrong. It’s evidence that conversations about screen time often start from different premises, which is why they tend to stall.
Parents in the study were broadly negative about all three platforms. Teenagers were more mixed — most described their experience as roughly equal in positive and negative effects, rather than harmful overall.
What to do with this
The sleep figure is the most actionable thing in the study. Check your child’s screen time data for TikTok specifically — most phones break this down by app. If TikTok is running past 10pm regularly, that maps directly to what 37% of teen users are reporting.
The perception gap is worth naming directly rather than working around. Showing your teenager the 44% vs 28% figure and asking what they think about it tends to open a more honest conversation than asserting they spend too much time on their phone.
And if your child is posting frequently on Snapchat, that’s a different kind of engagement than watching TikTok for two hours without interacting.
