A complete guide to the ages of Eleven, Will, Mike, Lucas, Dustin, and the rest of the Hawkins crew in the final season. With Stranger Things 5 dropping next week, fans are already reviewing every detail before watching the final chapter.
One thing people always ask before a new season is how old the characters are now that the actors have grown up so much. Because the show jumps through time and the Hawkins kids have dealt with more danger than most action heroes, it’s easy to forget where everyone stands age-wise.
Here’s a simple guide to how old each main character is in Stranger Things Season 5 and how their ages compare to the actors.
Eleven
- Character age in Season 5: 17
- Actor age: Millie Bobby Brown is 21.
The show keeps Eleven in the same high school timeline that started in Season 4, so she’s still a teen even though Brown is now an adult.
Mike Wheeler
- Character age in Season 5: 17
- Actor age: Finn Wolfhard is 22 (turning 23 on December 23, 2025).
Mike stays the same age as Eleven and the rest of the main group.
Will Byers
- Character age in Season 5: 17
- Actor age: Noah Schnapp is 21.
Will is the same age as Mike and Eleven, even though Schnapp is a bit older than his character.
Lucas Sinclair
- Character age in Season 5: 17
- Actor age: Caleb McLaughlin is 24.
Like the others, Lucas is still a high school senior.
Dustin Henderson
- Character age in Season 5: 17
- Actor age: Gaten Matarazzo is 23.
Dustin is the same age as the rest of the main group, even though Matarazzo has aged ahead of the character.
Max Mayfield
- Character age in Season 5: 17
- Actor age: Sadie Sink is 23.
Max is also 17, though her story after Season 4’s ending — where she was in a coma — makes her return more emotional.
Nancy Wheeler
- Character age in Season 5: 19
- Actor age: Natalia Dyer is 30.
Nancy is still a late teen, even though Dyer is ten years older.
Jonathan Byers
- Character age in Season 5: 20
- Actor age: Charlie Heaton is 31.
Jonathan has one of the biggest age gaps between actor and character but still fits the role of a young adult.
Steve Harrington
- Character age in Season 5: 20
- Actor age: Joe Keery is 33.
Steve stays in his early twenties, and fans often joke about how much older Keery is now.
Robin Buckley
- Character age in Season 5: 19
- Actor age: Maya Hawke is 27.
Robin is close in age to Nancy and Steve in the show, even though Hawke is older in real life.
Stranger Things has always mixed teenage drama with huge supernatural threats, so the age differences between the cast and their characters can be surprising.
Still, the character ages follow the show’s timeline, which stays in the mid-to-late ’80s. With the final season arriving on November 26, 2025, fans will finally see how these older teen heroes face their last fight against the Upside Down.
