Everyone’s patiently waiting for Stranger Things season 5 to be released on Netflix, but it looks like it’ll be a while before we get to see the final season. With an expected release sometime in 2024, we’ve been keeping ourselves busy in the meantime by researching everything we can about the amazing cast.

The main cast were all very young when the science fiction series premiered in 2016. Viewers have watched them pretty much grow up on-screen as the seasons have gone on. Of course, there were also many new cast additions to the show, and we watched them grow up as well. And with the cast aging, you can see the complete transformations in their physical appearances, especially the boys.

So, how old was the Stranger Things cast when the show first premiered? How old are they now in 2023? As always, we’ve got the answers.
