Time is a weird thing when you’ve basically grown up alongside the world's most famous twins. It feels like just yesterday we were watching Michelle Tanner eat ice cream or the girls solving crimes before dinner in their trench coats. But here we are. It’s 2026.
Honestly, the question of how old mary kate and ashley are is one of those things that makes you feel instantly ancient.
The Big Milestone: 40 Is Just Around the Corner
Right now, both Mary-Kate and Ashley Olsen are 39 years old. They were born on June 13, 1986.

If you’re doing the math for this year, they’ll be hitting the big 4-0 this coming June. It’s wild to think about because, in our collective pop culture brain, they’re sort of frozen in time as those "cool older sisters" from the direct-to-video era. But in reality, they’ve spent more of their lives as high-fashion moguls than they ever did as child actors.
A Quick Breakdown of Their Timeline
- 1986: Born in Sherman Oaks, California (Ashley is technically two minutes older).
- 1987: They land the role of Michelle Tanner at just nine months old.
- 2004: They turn 18, take over their company Dualstar, and release their last film together, New York Minute.
- 2006: The Row is founded—changing the fashion world forever.
- 2026: They turn 40.
Why Their Age Still Fascinates Everyone
People aren't just googling their age because they forgot a birthday. It’s because the Olsens have pulled off the ultimate Hollywood vanishing act. Most child stars either burn out or stay in the spotlight until we’re sick of them. These two? They just... left.
They don't have Instagram. They don't do TikTok dances. They rarely even give interviews anymore.

Because they’ve been so private, every time a paparazzi photo surfaces of them in the Hamptons or at a fashion show in Paris, there’s this immediate "Wait, how old are they now?" reaction. We're looking for signs of the kids we knew in the faces of the women they’ve become.
Different Paths, Same Birthday
Even though they’re twins and business partners, their lives look pretty different these days.
Ashley is a mom now. Back in 2023, news broke that she and her husband, Louis Eisner, welcomed a son named Otto. She kept the entire pregnancy a secret—classic Ashley. By the time 2026 rolled around, she’d fully settled into this "quiet luxury" motherhood vibe that everyone is trying to copy.
Mary-Kate has been more in the news for her equestrian career. She’s a serious competitive rider. If you follow the horse world, you know she’s not just a "celebrity who rides"; she’s actually out there competing in the Longines Global Champions Tour and placing. After her very public divorce from Olivier Sarkozy a few years back, she seems to have found her peace in the stables and the design studio.
What Most People Get Wrong About Them
A lot of people think they’re "retired." That’s hilarious.
They might be retired from acting, but they work more than most people I know. They run The Row, which is basically the gold standard for luxury right now. They aren't just figureheads; they are the ones choosing the fabrics, obsessing over the fit of a $500 T-shirt, and deciding that, for the Summer 2026 collection, they were going to lean into a more maximalist, opulent look.
They’ve been in the "business" since they were in diapers. That’s 39 years of being professional. When you look at it that way, they have more career seniority than most CEOs in their 60s.
The "Quiet Luxury" Pioneers
If you’ve heard the term "quiet luxury" lately, you can thank the Olsens. They were doing the "no-logo, high-quality, hidden wealth" thing a decade before it became a hashtag. They basically taught a whole generation that you don't need to scream to be heard.
It’s sort of a metaphor for their lives. They don't need to be on a red carpet every night to be relevant. Their age—approaching 40—marks a new era where they are no longer the "young disruptors" in fashion; they are the establishment. They are the veterans.
Actionable Takeaways for Olsen Fans
If you’re looking to keep up with them in 2026, here’s the best way to do it without falling for tabloid clickbait:
- Watch the Runway, Not the Red Carpet: They rarely attend movie premieres, but they are always at their own shows in Paris or New York. Look at the "Summer 2026" collection reviews for the best glimpses of their current aesthetic.
- Follow the Equestrian Circuit: If you want to see Mary-Kate in her element, check out the official results for major showjumping events.
- Respect the Privacy: Part of their "brand" is the mystery. If you’re looking for a tell-all memoir, don't hold your breath. It's never coming.
The reality is that how old mary kate and ashley are doesn't matter as much as the fact that they’ve stayed true to themselves. They outran the child-star curse by becoming the most serious people in the room. Whether they're 39, 40, or 60, they’ll probably still be wearing oversized black coats and making us all wish we had their discipline.
