Between chasing down the Demogorgon, venturing through the Upside Down, and taking on the Mind Flayer… The kids of Stranger Things really are superstars these days.

And whilst the characters are all in their early and late teens, we know that actors are rarely ever matched to a role via their age.

So how old exactly are our fave actors…?

1. Eleven (Millie Bobby Brown) – Aged 12

When we first met Eleven back in Season 1, among many other things, we found out that she was born in 1971. This means that she was 12-years-old.

By the time Season 2 rolled around, Eleven had spent a year secluded with Hopper, so she was 13-years-old.
