Time is a weird thing. One minute you're watching a toddler in a ponytail say "You got it, dude," and the next, she’s a billionaire fashion mogul running a global empire from a hidden office in Manhattan. If you've been wondering how old is the olsen sisters, you aren't alone. It's one of those questions that hits with a sudden realization of how much time has actually passed since the 90s ended.
As of right now, in early 2026, Mary-Kate and Ashley Olsen are 39 years old.
They were born on June 13, 1986. That means they are creeping up on the big 4-0 faster than any of us who grew up with their VHS tapes are probably comfortable admitting. But they aren't the only ones in the family tree making waves anymore. Their younger sister, Elizabeth Olsen, who has arguably become the most visible member of the trio, is 36 years old. She was born on February 16, 1989.
It’s a strange phenomenon. We’ve known them for nearly forty years, yet they remain some of the most private, enigmatic figures in Hollywood—or, more accurately, the fashion world.
The Age Gap and the "Full House" Legacy
The math is simple but the impact is heavy. Mary-Kate and Ashley started their "job" when they were just nine months old. Most of us were still struggling with mashed peas, and they were already sharing the role of Michelle Tanner. By the time Full House wrapped in 1995, the twins were only nine.
Think about that for a second.

They had already completed eight seasons of a hit sitcom before they even hit double digits. Elizabeth, meanwhile, was just a little kid watching from the sidelines. For years, she was just "the other sister." While Mary-Kate and Ashley were building a literal empire under the Dualstar banner—think movies like It Takes Two and Passport to Paris—Elizabeth was off doing normal kid stuff, which is probably why she seems so much more grounded in interviews today.
Honestly, the way they've aged out of the spotlight is a masterclass in rebranding. You don't see them on TikTok. You don't see them at every award show party. They chose a path of "quiet luxury" before that was even a buzzword.
Why Everyone Still Asks How Old is the Olsen Sisters
People get confused because the twins basically "retired" from acting when they were 18. Their last major film together, New York Minute, came out in 2004. Because they vanished from our TV screens so abruptly, our collective memory of them is sort of frozen in that late-teen, boho-chic era.
But they haven't been idle. Far from it.
The Evolution of The Row
While we were busy asking how old is the olsen sisters, they were busy turning their brand, The Row, into a billion-dollar powerhouse. By 2026, The Row has become the gold standard for high-end fashion. We’re talking about $500 T-shirts and $4,000 coats that don't even have a visible logo.

- Mary-Kate serves as the Creative Director.
- Ashley is the CEO.
- They’ve won five CFDA awards (the Oscars of fashion).
They aren't just "celebrity designers" anymore. They are respected peers of people like Marc Jacobs and the late Karl Lagerfeld. In 2024, the brand even took on major investments from big players like the Wertheimer family (who own Chanel) and the L’Oréal heiress. It’s a serious business, and they’ve been doing it for twenty years now.
Elizabeth Olsen: The Marvel Powerhouse
Then there’s "Lizzie." At 36, she’s in the absolute prime of her career.
While her sisters were exiting the stage, she was just getting started. She didn't really break out until Martha Marcy May Marlene in 2011, and then, obviously, the Marvel Cinematic Universe happened.
In 2025 and 2026, her schedule has been packed. Between voicing variants of Wanda Maximoff in Marvel Zombies and starring in prestige dramas like His Three Daughters, she has successfully carved out a completely different legacy. She’s the sister you see on the red carpet. She’s the one doing the late-night talk show circuit.
It’s a fascinating family dynamic. You have the twins, who are 39 and obsessed with privacy and textiles, and the younger sister, 36, who is one of the most bankable movie stars on the planet.

What Most People Get Wrong About the Twins
There is this persistent myth that the twins are "reclusive" because they’re unhappy.
Kinda the opposite, actually.
They just don't want to be famous for being famous. Mary-Kate has spent a lot of her 30s as a competitive equestrian. She’s been spotted at the Longines Global Champions Tour, which is a world away from the paparazzi-heavy streets of Los Angeles.
Also, can we talk about the Margaux bag? In late 2024 and throughout 2025, that bag became the new Birkin. People were losing their minds over it. It proves that even though they are nearly 40, they still have their fingers on the pulse of what people want to wear. They aren't "former child stars" anymore. They are the bosses.
Looking Toward the Future
So, what’s next for the sisters as they approach the end of their 30s?
- The Big 4-0: June 13, 2026, will be a massive milestone for Mary-Kate and Ashley. Expect a very private, very expensive dinner somewhere in Europe that no one will see photos of.
- Global Expansion: The Row is currently opening more flagship stores, moving beyond just New York and Paris into more niche luxury markets.
- Elizabeth's New Projects: Keep an eye out for her upcoming vampire thriller Flesh of the Gods with Oscar Isaac. It’s expected to be a huge departure from her superhero work.
Honestly, the fascination with their age usually stems from a place of nostalgia. We want to know how old they are because it helps us track where we are in our own lives. If the Olsen twins are almost 40, then we’re definitely not kids anymore either.
If you’re looking to channel that classic Olsen energy, start by simplifying. The sisters have spent their 30s proving that "less is more." Whether it’s their skincare routines or their wardrobes, they favor quality over quantity. For a practical next step, look into the concept of a "capsule wardrobe"—investing in three or four high-quality pieces rather than twenty cheap ones. It’s the philosophy that turned two child stars into the most formidable duo in fashion history.
