What Age Should Kids Be on Social Media? A Parent's Guide

If your child is asking to join a social app "because everyone else has it," you're not alone! And you're right to pause before saying yes. So what age should kids be on social media? The short answer: most major platforms set the minimum at 13, but the research shows children are joining far earlier, which makes how they start matter just as much as when.

The data: kids across Europe are joining much younger than the rules allow

The official cut-off is 13. Across Europe, reality looks very different.

A 2025–26 EU Kids Online study of 29,169 children across 19 European countries found that social media use climbs steeply with age: around half of 9-year-olds already use it, and by age 13 almost all do. Crucially, most children who use social media opened their accounts before turning 13 including 79% of Snapchat users and 74% of TikTok users.

A separate EU survey on children's screen time and wellbeing, reported by the European Commission, found children spend on average 4.5 hours online on school days and over 6 hours at weekends and those who start before age 10 tend to rack up the most screen time of all.

In other words, by the time your child reaches 11 or 12, this is no longer a hypothetical conversation, it's one most European families are actively having.

Why the minimum age is 13?

The age limit isn't random. It comes from privacy law, not from a judgment that children magically become "ready" on their 13th birthday.

It's about data, not maturity

Under EU and UK data-protection law (the GDPR), 13 is broadly the age at which a child can agree to an online service handling their personal data on their own. Below that, a parent must consent. Many mainstream platforms simply set their minimum age at 13 so they don't have to build for younger children at all. But as the European research above shows, that line is crossed constantly, which is exactly why lawmakers across Europe are now debating whether the threshold should be raised further. So when an app says "13+," it's often a legal decision about data, not a sign the app is genuinely safe or suitable for a 13-year-old.

"13" doesn't mean "ready"

Plenty of 13-year-olds aren't ready for open, adult-facing platforms, and some younger children can handle a safe, age-appropriate app well. Readiness depends on the child and the platform, which is why the better question isn't only "how old?" but "is this the right kind of space for my child right now?"

What Age Should Kids Be on Social Media for Your Child? How to Tell If They're Ready

Age is a starting point, not the whole answer. Signs your child may be ready for a first, supervised step into social apps include:

• They can tell you what personal information should never be shared online (full name, school, address, location).

• They come to you when something feels wrong, instead of hiding it.

• They understand that not everyone online is who they say they are.

• They can handle disappointment and disagreement without it ruining their day.

• They follow other household rules (screen time, bedtime) reasonably well.

If most of these aren't true yet, that's not a "no" forever, it's a sign to keep building the skills first.

A smarter first step than mainstream social media

For children aged 7–13, jumping straight onto an adult platform built for billions of strangers is a big leap. A safer path is to start on a platform designed specifically for their age group, where safety is built in rather than bolted on.

That's exactly the gap Momio is built to fill. Kids play under a nickname and avatar rather than their real identity, chat is filtered, images and videos are reviewed before they go live, and reporting tools are easy to find and use. Safety isn't a marketing line, it's set out in Momio's CSAE Declaration, our zero-tolerance policy on child sexual abuse and exploitation, which details how content is moderated, how concerns are reported, and how parents grant or withdraw consent for a child's account. It gives children a place to play, create, and connect with the social experience they're craving. If safety is your first question (it should be), read our full guide: Is Momio a Safe Social Media for Kids?

Starting somewhere age-appropriate also lets your child practice the habits, kind communication, guarding personal info, telling an adult when something's off, that they'll need later on the bigger platforms.

How to set your child up for success

Whenever you decide the time is right, a few habits make all the difference:

1. Set it up together. Create the account side by side and walk through the privacy settings as a team.

2. Agree on the rules first. What's okay to share, who they can talk to, and when devices go away (decided before, not during, a conflict).

3. Keep the door open. Children are far more likely to come to you about a problem if they know you'll listen calmly rather than confiscate the device.

4. Check in, don't just monitor. Ask what they enjoy and who they talk to. Curiosity builds more trust than surveillance.

The bottom line

So, what age should kids be on social media? Thirteen is the legal floor for most mainstream platforms, but the right age for your child depends on their maturity and, crucially, the platform you choose. For 7–13 year-olds, a purpose-built, moderated space is a far safer first step than the open internet. Start there, build the skills, and you'll set your child up to handle the bigger platforms when the time comes.
