How Old Is Eleven in Stranger Things Season 4? (Compared to the Other Seasons)

Ever since the release of the first season of Stranger Things in 2016, we have followed the story of children and teenagers that were fighting off demonic monsters and creatures in their town of Hawkins, Indiana. Helmed by the talented Millie Bobby Brown’s character known as Eleven, the series has become a global sensation. We have also seen Eleven and the other kids grow in front of our very eyes as we are now in the fourth season of the series. But how old is Eleven in Stranger Things season 4?

Eleven is currently 15 years old in Stranger Things season 4. Every season has a different time skip of one year, and the series began in 1983, with Eleven still 12 years old. As such, she was 13 in season 2, 14 in season 3, and is now 15 years old and in her freshman year in high school in season 4.

The best thing about Stranger Things is that we were able to see the actors and their characters grow up in front of our very eyes. In a sense, a lot of us grew up with them as well because we were able to follow how they grew and matured from the very first season. So, with that said, let’s look at how old Eleven is in Stranger Things season 4 and how old she was in the first three seasons.

How Old Is Eleven In Stranger Things Season 4?

Stranger Things is one of the series that made Netflix into what it is right now, as it is arguably the greatest Netflix original. It has been around since 2016 as it steadily sneaked into pop culture when people realized just how good this series is. And the series follows the story of children who are in the middle of something bigger than they are because they are seeking to stop a supernatural event from taking over their small town of Hawkins, Indiana.

As mentioned, Stranger Things follows the story of children as the main characters of the series. This cast of children is helmed by the talented Millie Bobby Brown, who plays the role of the superpowered young girl named Eleven, who has some sort of psychic and telekinetic abilities that allow her to push things with her mind. Eleven has since been the hero of the series as she explored her powers to stop the supernatural events of Stranger Things while learning how to be a normal girl after living in an experiment facility throughout her entire life.

We basically saw how all of the kids in Stranger Things grew up every season. Eleven and her friends experienced what it was like to be young kids that are now currently in the middle of their teenage years in a series that is just as much about a coming-of-age story about the main characters just as much as it is a fantasy-horror story.

As such, in season 4, Eleven and her friends are already in their freshman year in high school. Meanwhile, their older teenage friends are already in their young adult years, with Steve and Robin working in a VHS rental store and Nancy and Jonathan looking to go to college. Meanwhile, the main cast of kids is still starting out in their high school years as Eleven is now in California after she and Will’s family were asked to move out of Hawkins for their safety.

In season 4, it is clear that Eleven is now a young lady and is looking to try to live a normal life after she lost her powers at the end of season 3. Of course, her journey included a lot of growing pains that teenagers go through. So, how old is Eleven in season 4 of Stranger Things?

Right now, in season 4, Eleven is 15 years old, just like how Mike, Will, Dustin, Lucas, and Max are also 15 years old and in their freshman years in high school as well. However, the actress, Millie Bobbie Brown, is currently 18 years old after she started with the project at the age of 12.

We now see how grown-up Eleven is because she is now dealing with normal problems that teenagers normally experience in their lives. These problems include friendship, romance, and bullying, as she is now looking more like a normal girl.

How Old Was Eleven In The Other Seasons?

Throughout the entire four seasons of Stranger Things, we were able to see Eleven and the other kids grow up both in the figurative and the literal senses because the adventures they went through made them grow as individuals. Of course, they also grew older off-screen throughout the course of the four seasons. But how old was Eleven in the first three seasons?

Season 1

Released in 2016, Stranger Things season 1 was what introduced us to Millie Bobbie Brown’s Eleven, a young girl who escaped from an experimental facility and is in possession of powers that allow her to push things with her mind. The very same season also allowed us to meet all of the other kids as Mike, Dustin, and Lucas were trying to solve a mystery that led to the disappearance of their friend named Will, who they believe was taken to the Upside Down.

At this time, all of the Stranger Things kids were just 12 years old, and that means that Eleven herself was still just 12 as well. Meanwhile, Millie Bobbie Brown, born in 2004, was still only 12 years old when she first portrayed Eleven.

Season 2

Season 2 of Stranger Things takes place a year after the events of season 1, as we see how the characters have matured off-screen during that time skip. In that regard, in season 2, Eleven and the other kids are now in their early teenage years as they are now 13 years old during the events of season 2. It was also during season 2 that Max, another 13-year-old girl, was introduced as the sixth member of the group.

Considering that season 2 was released only a year after season 1, Eleven and Millie Bobbie Brown are just about the same age. 

Season 3


In season 3 of Stranger Things, the events happen a year after the conclusion of season 2. This time, the kids are now living lives that are seemingly quite normal because they are now able to enjoy some of the things that young teenagers are supposed to enjoy. They were able to go to the mall and hang out together, all while experiencing young romance.

This time, as Eleven is now in a budding young romance with Mike, she is 14 years old. At the release of season 3, which premiered in 2019, Millie Bobbie Brown was already 15 years old and was only a year older than her on-screen character. However, right now, she is three years older than Eleven, considering that there was a three-year gap between the release dates of seasons 3 and 4.
