Stranger Things kids growing up; Find out their real ages in 2025!

As Stranger Things approaches its highly anticipated final season, fans are taking a moment to reflect on how dramatically its young stars have grown since the series premiered in 2016. While the supernatural saga has only advanced a few years within the world of Hawkins, the actors behind the beloved characters have transitioned from early teens to full-fledged adults. Their real ages in 2025 may surprise longtime viewers who still think of them as the bike-riding kids from Season 1.

Millie Bobby Brown, who plays Eleven, is now 21 years old. She was just 12 when audiences first met her as the mysterious girl with extraordinary powers. While Eleven remains around sixteen in the story, Brown has evolved into one of Hollywood’s most influential young women—starring in films, producing major projects, and building a beauty empire. Her maturity and presence off screen contrast sharply with her still-teenage persona on the show.

Sadie Sink, who joined Stranger Things in Season 2, is 23 in 2025. Her character Max Mayfield continues to embody teen angst and courage, though Sink herself has blossomed into a critically acclaimed actress known for dramatic film roles. Her powerful performances make the age gap nearly invisible on screen.

Noah Schnapp, who was just 11 when filming began, is now 21. His character Will Byers, whose disappearance launched the series, remains a central figure and is still presented as a teenager. In reality, Schnapp has taken on new ventures, including business and advocacy work, while balancing the emotional demands of portraying Will in the show’s final chapter.

At 24 years old, Caleb McLaughlin is the eldest of the original “kids” cast. His character, Lucas Sinclair, is still portrayed as a mid-teen navigating friendship, love, and supernatural dangers. Off screen, McLaughlin has embraced a variety of acting roles and continues to explore music and fashion. His evolution from the athletic kid in Season 1 to a sophisticated young man is one of the most striking of the cast.

Gaten Matarazzo, now 23, remains one of the most beloved cast members thanks to his energy and charm as Dustin Henderson. Despite Dustin being about 16 in Season 5, Matarazzo’s real-life journey includes starring on Broadway, hosting television projects, and lending his voice to animated films. His youthful exuberance helps maintain the illusion of a much younger character—even as he steps confidently into adulthood.

Finn Wolfhard, the actor behind Mike Wheeler, is 22 and will turn 23 later in 2025. Though Mike is still written as a teen, Wolfhard’s career has expanded far beyond Hawkins. He's directed short films, released music with his band, and acted in several major movies. His height, deeper voice, and increasingly adult presence are reminders of just how long fans have been watching him grow.
