Average Screen Time for Gen Z: The Real Numbers
The average screen time for Gen Z teens in the US is roughly 8 to 9 hours a day of entertainment screen use, according to Common Sense Media's 2021 census of 13 to 18 year olds, and that doesn't even count schoolwork. Social media alone is closer to 5 hours a day for US teens in Gallup's 2023 survey. Numbers vary a lot between surveys, and below we explain why.

The number in one line
Most sourced surveys put US teens (the younger half of Gen Z) at about 8.5 hours of screen time a day for fun, with around 5 of those on social media.
That's for teens. Older Gen Z (roughly born 1997 to 2012, so in their early-to-late 20s now) is harder to pin down because fewer surveys separate them from other young adults.
What the surveys say (Gen Z screen time stats)
Here are the figures we're confident in, with where they come from.
| Source | Who | What it measured | Result |
|---|---|---|---|
| Common Sense Media census (2021) | US teens, 13-18 | Entertainment screen media per day (not school) | About 8 hours 39 minutes |
| Common Sense Media census (2021) | US tweens, 8-12 | Entertainment screen media per day | About 5 hours 33 minutes |
| Gallup (2023) | US teens, 13-19 | Time on social media per day | About 4.8 hours on average |
| Pew Research Center (2024) | US teens, 13-17 | How often they're online | Nearly half said "almost constantly" |
A few things stand out:
- "Almost constantly" is now normal. Pew found close to half of US teens describe themselves as online almost constantly. That's a vibe more than a number, but it's telling.
- Social media is the biggest chunk. Gallup's teens averaged nearly 5 hours a day across platforms, with YouTube and TikTok taking the most time.
- School screen time is extra. Common Sense's numbers exclude homework and class use, so real total screen time is higher on school days.
For the UK and Canada, national regulators and statistics agencies (like Ofcom in the UK and Statistics Canada) publish their own reports on young people and screens. Their methods differ from the US surveys, so the numbers aren't directly comparable, but the pattern is similar: teens spend hours a day online, and a lot of it is video and social apps.
What we won't do: quote viral stats like "Gen Z spends 11 hours a day on their phones" without a clear source. A lot of stat-roundup pages copy each other, and the original survey is sometimes impossible to find.
Why the numbers don't match
Search "average screen time for teens" and you'll see answers from 3 hours to 11. Here's why:
They measure different things
- All screens vs phones only. TV, gaming, laptops and phones add up fast.
- Entertainment only vs everything. School and work screen time can add hours.
- Social media only vs total. Gallup counted social media; Common Sense counted all entertainment media.
They ask different people
Ages vary: 13-17, 13-19, 16-24, 18-29. A 14-year-old and a 24-year-old office worker are both "Gen Z" but live very different screen lives.
They collect data differently
- Self-report: people guess, and they usually guess low.
- Tracked data: apps read actual phone use, but the people who install tracking apps might not be typical.
They're from different years
Screen time jumped during 2020 lockdowns. A 2019 number and a 2024 number aren't the same world.
Multitasking gets counted twice
Watching Netflix while scrolling TikTok? Some surveys count that as two hours for every hour. That's how you get totals that seem impossible.
Gen Z vs Gen Alpha screen time
Gen Alpha (born roughly 2010 onward) are the kids and younger teens growing up with tablets from toddlerhood.
- Average screen time for Gen Alpha tweens: Common Sense's 2021 census found 8 to 12 year olds averaged about 5.5 hours a day of entertainment screen media.
- The jump happens around the teen years. Screen time rises sharply when kids get their own phones and join social apps.
- Different favorites. Younger kids lean more on YouTube and games; teens add TikTok, Snapchat and Instagram.
So average screen time by age looks roughly like this: it climbs through the tween years, peaks in the teens and early twenties, and stays high for young adults who work on screens too.
Which apps eat the most time
From the teen surveys above, the heavy hitters are the same ones you'd guess:
- YouTube: used by the vast majority of US teens in Pew's surveys, and a top time-spender in Gallup's.
- TikTok: the other top time-spender in Gallup's survey, and used by roughly six in ten teens in Pew's data.
- Instagram: similar reach to TikTok among teens.
- Snapchat: big for messaging, streaks and staying in the loop.
- Games and streaming: Fortnite, Roblox, Netflix, Twitch and the rest fill in the gaps.
Fast, endless feeds are built to keep you watching, which is why "5 minutes" on TikTok is never 5 minutes. Want to see how often you actually reach for your phone? Our guide to what pickups mean on screen time shows you where to find that number.
Here's the catch with averages: they tell you about everyone, not you. And your Screen Time total alone doesn't say whether your use is fine or taking over your day. Brainrot Test asks 17 questions about what you actually do when you pick up your phone, gives you a score from 0 to 100 and shows how you compare with everyone else. It also has a screen-time calculator. Check my brainrot
Where you stand
Some honest context:
- Being "average" doesn't mean it's fine for you. If you're sleeping badly, missing deadlines or feeling foggy, that matters more than the class average.
- Being above average doesn't mean you're doomed. Tons of screen time can be group projects, messaging family abroad, or a creative hobby.
- What you do matters as much as how long. Two hours editing a video is different from two hours doomscrolling.
Quick check:
- Open Screen Time (iPhone) or Digital Wellbeing (Android) and note your daily average.
- Look at your top three apps.
- Ask: which of these would I miss, and which do I open on autopilot?

FAQ
What is the average screen time for Gen Z per day?
For US teens, the best-known figure is about 8 hours 39 minutes a day of entertainment screen media, from Common Sense Media's 2021 census. Social media alone was about 4.8 hours a day for US teens in Gallup's 2023 survey. Older Gen Z adults are less studied, and figures vary.
Is 8 hours of screen time bad?
Not automatically. It depends on what those hours include (school, work, messaging family, gaming, scrolling) and whether it's crowding out sleep, movement and focus. If your screen time is making it hard to do things you care about, that's the signal to cut back.
What is the average screen time for Gen Alpha?
Common Sense Media's 2021 census found US tweens aged 8 to 12 averaged about 5 hours 33 minutes a day of entertainment screen media. Screen time usually rises when kids get their own phones in their early teens.
Why do Gen Z screen time stats vary so much?
Surveys measure different things (all screens vs phones, social media vs everything), ask different age groups, and use self-reports or tracking apps. Some count multitasking twice. Always check who was asked and what was measured.
How can I tell if my screen time is normal?
Compare your Screen Time or Digital Wellbeing average with the survey numbers above, then look at how it feels: are you sleeping, getting work done and enjoying offline time? A quiz like Brainrot Test can also show how your habits compare with other people's.
