Now Kendall is 30, these are the surprising age gaps between the Jenners and Kardashians
One sister was graduating college when Kenny was in diapers
Kendall Jenner turning the big 3-0 this November officially signals that she and Kylie are really no longer the “babies of the family” any more. It’s pretty much the end of an era.
She’s grown up in front of the cameras, gone from walking Chanel runways to running tequila empires, and somehow managed to stay the most low-key Kardashian-Jenner going.
But with her milestone birthday, it’s wild to look at just how spread out the family really is. From Kourtney’s mom-of-four energy to Kylie’s glam-girl chaos, here’s how their ages stack up, and which sibling she’s actually closest to.
Kourtney Kardashian – Born April 18, 1979

Kourtney is the OG of the group, the eldest sister and the one who had Poosh figured out before wellness became a thing. She’s 16 years older than Kendall, meaning she was graduating college when Kenny was still in diapers.
Their dynamic has always been the classic ‘responsible big sister meets cool younger sibling’ energy, though these days, Kourtney’s busy being a rockstar wife and mom while Kendall’s building her own empire.
Kim Kardashian – Born October 21, 1980

Kim might be the pop-culture powerhouse of the family, but she’s also 15 years older than Kendall. That’s practically a whole high-schooler apart!
When Kendall was watching cartoons, Kim was already organising closets for Paris Hilton and plotting her reality TV takeover.
Khloé Kardashian – Born June 27, 1984

Khloé’s the sister you’d want to grab a margarita with, fun, funny, and full of brutally honest one-liners.
She’s 11 years older than Kendall, so she’s kind of the perfect middle ground between the OGs and the Jenners.
Over the years, Kylie’s called Khloé her “second mom,” and we all saw her take on the caregiver role to her youngest sisters during the early Keeping Up With the Kardashians days.
Koko and Kenny’s energy together is a mix of big-sister advice and younger-sister eye-rolls, in the most loving way.
Rob Kardashian – Born March 17, 1987

Rob doesn’t pop up much these days, but he’s still the only Kardashian brother.
He’s eight years older than Kendall, which explains why he was the quiet protective type when the youngest sisters joined the show.
These days, Rob keeps things pretty private, but Kendall has mentioned he’s a softie with all the nieces and nephews.

Now the birthday girl herself! Kendall officially hitting 30 years old feels like a full-circle moment for fans who watched her grow up on E!.
She’s the middle-child-vibe personified, not as “mom mode” as her older sisters, not as chaotic as Kylie, but solidly in her confident adult era.
Between 818 Tequila, her modelling career, and her super-chill approach to fame, she’s the sibling who makes balance look cool.

Kylie is Kendall’s closest sister in both age and vibe, just two years younger, which makes them the duo we’ve seen clubbing, contouring, and likely bickering over borrowed clothes.
They’re practically twins in how close they are, though Kendall’s always been the more private one. It’s safe to say Kylie’s still the baby in Kendall’s eyes (even if she has two kids and a billion-dollar beauty brand).
Kris Jenner – Born November 5, 1955

We couldn’t leave out the momager who started it all.
Kris is 40 years older than Kendall, and still somehow keeps up with every brand launch, baby name, and boyfriend update in the family.
She’s said before that Kendall reminds her of herself “at that age,” which probably means the tequila-and-timetable combo runs in the genes.
