How Old Is Kendall And Kylie Jenner

Ever wonder how old Kendall and Kylie Jenner actually are? You might be shocked to learn they’re not the same age, despite growing up together on TV. In fact, there’s a bigger age gap between them than you think.

The big numbers

Kendall Jenner was born on November 3, 1995. That makes her 29 years old as of 2025. Kylie Jenner, the baby of the family, was born on August 10, 1997, which makes her 27 years old.

So they’re just under two years apart — exactly 1 year, 9 months, and 7 days. That’s close enough to be best friends, but far enough that Kendall remembers life before Kylie was even a toddler.

The funny part

Here’s where it gets hilarious: Kylie is now older than Kendall was when Keeping Up with the Kardashians first aired. In 2007, Kendall was 11 and Kylie was a chubby-cheeked 10-year-old.

Back then, Kylie was the little sister who always tagged along. Now she’s a billionaire makeup mogul with her own daughter, Stormi. Time flies when you’re busy becoming famous.

The confusing math

Because they’re so close in age, people mix them up all the time. A common Google search is: “Which Jenner sister is older?”

Spoiler alert: It’s Kendall. Always has been, always will be.

But here’s a fun fact: Kylie is actually older now than Kendall was when Kylie turned 18. That’s a brain-twister, but it’s true. Kendall was 19 when Kylie became legal, and now Kylie is 27.

The heartwarming twist

Despite the jokes, their age difference is what made them so tight. Kendall protected Kylie from the chaos of fame when they were teens. Kylie once said Kendall was her “rock” during the early modelling days.

Now that they’re both adults, they’re practically twins. They shop together, vacation together, and even share the same friend group. Age is just a number when you’ve survived the same reality show drama.

The unexpected milestone

Kendall hit a weird milestone in 2024: she turned 29, which is older than Kris Jenner was when she had Kim. Kris was 28 when Kim was born. So Kendall is now at the age her mom became a mom for the third time.

Meanwhile, Kylie became a mom at 20 — younger than both Kendall and Kris. That’s a wild contrast. One sister is all about runway shows, the other is building a mini dynasty.

The takeaway

So how old are Kendall and Kylie? They’re 29 and 27, but they’ll always be the two sisters fighting over a hairbrush on our TV screens. The math is simple: Kendall is older, Kylie is younger, and both are forever a little bit confused about their ages.

Next time someone asks, just smile and say: “Kendall is the one who was born first. Kylie is the one who became a billionaire first.” That’s the easiest way to remember.
