If you’ve spent any time on K-pop Twitter or TikTok lately, you’ve definitely seen her. The sharp bob, the "Antifragile" core, and that specific brand of "don't mess with me" charisma. But for new fans—or even old ones trying to keep track of the timeline—the question how old is Chaewon usually pops up pretty quickly. It feels like she’s been around forever, right? From the Produce 48 days to IZ*ONE and now leading one of the biggest groups in the world, Kim Chaewon has had about three different career peaks, and she’s still remarkably young.
Honestly, it’s a bit of a mind-bender. She has the poise of a veteran because, well, she is one. But in terms of actual years on this planet, she’s right in that sweet spot where she’s mature enough to lead a powerhouse like LE SSERAFIM but young enough to keep pushing the boundaries of what a "K-pop idol" looks like.
The Short Answer: Kim Chaewon’s Age Right Now
Let’s get the numbers out of the way first. Kim Chaewon was born on August 1, 2000. Since we are currently in early 2026, that makes her 25 years old.
If you’re reading this before August 1st, she’s still 25. Once August hits, she’ll be turning 26. In the industry, 25 is often considered "older" for a girl group member, which is frankly ridiculous when you look at her energy on stage. She’s a Leo, which explains the natural leadership and why she basically owns every stage she walks onto.
She was born in Gangnam, Seoul, and if you’re into the details, she stands about 163 cm (roughly 5'4"). She’s not the tallest in the group, but her proportions and that signature short hair make her look a lot taller than she actually is.
Why People Get Confused About Her Age
The reason people constantly ask how old is Chaewon is because her vibe shifted so drastically between 2018 and now.
Back in the IZONE days, she was known as "Angel Chaewon." She had long hair, did the "cute" concept perfectly, and was often seen as one of the softer members of the group. She was just 18 when she debuted with IZONE. When that group disbanded in 2021, she was 20.
Then, she disappeared for a bit.
When she re-emerged with LE SSERAFIM in 2022, she was 21 (turning 22). The "Angel" was gone. In her place was a leader with a blunt cut and an "I don't care" attitude. That "re-debut" made her feel like a brand-new rookie to some, while others remembered her as a teen idol. That 7-year gap from her first TV appearance to her current status in 2026 creates a weird "time dilation" effect for fans.

Growing Up in the Spotlight: The Timeline
It’s easy to forget how much she’s actually done. Here’s the breakdown of the life of Kim Chaewon:
- The Produce 48 Era (2018): She was 17-18 years old. She was a trainee under Woollim Entertainment and finished in 10th place.
- The IZ*ONE Years (2018–2021): She spent her late teens (18 to 20) in one of the most successful project groups in history.
- The Transition (2021–2022): A period of silence where she moved from Woollim to Source Music (HYBE). She was 21.
- LE SSERAFIM Era (2022–Present): Debuting as the leader at age 21, she’s now 25 and has navigated world tours, Coachella, and massive chart-toppers like "CRAZY" and "HOT."
Actually, seeing her at the Golden Disc Awards in Taipei recently (this was just days ago in January 2026), it’s clear she’s hitting her prime. They performed "SPAGHETTI" and she looked every bit the seasoned pro. At 25, she has a level of control over her performance that most rookies simply can't touch.
Is 25 "Old" for K-pop?
There’s this weird stigma in the K-pop world about age. People act like if you aren't 14, you're "late" to the game. But Chaewon is proving that’s nonsense. Being 25 in 2026 puts her in a position of power. She’s the leader of a group that includes Eunchae (who is significantly younger) and Sakura (who is older).
She’s basically the glue.

K-pop is changing. We’re seeing idols stay active way into their 30s now. Chaewon is part of that "Zillennial" bridge. She grew up with the old-school training but has the digital-savvy and "fearless" mindset of the newer generation. Honestly, her age is her biggest asset right now because she has the stamina of a 20-year-old and the experience of a 10-year veteran.
What’s Next for Chaewon?
As we look at the rest of 2026, LE SSERAFIM is wrapping up their "Easy Crazy Hot" world tour. There are rumors of more solo work for her too. She’s already proven she can carry a song by herself, and her vocals have gotten way more stable and textured over the years.
If you’re a fan, the best thing you can do is keep an eye on their official schedules. They just finished the Dick Clark’s New Year’s Rockin’ Eve show in the U.S., becoming the only K-pop group to do so this year.
Next Steps for FEARNOTs:
- Check the Tour Dates: They have encore concerts coming up at the Jamsil Indoor Stadium in Seoul (Jan 31 – Feb 1).
- Stream "HOT": It’s the track that’s currently dominating the 2026 charts.
- Follow her Instagram: She’s extremely active at @_chaechae_1.
Whether you're curious about her age because of a bet or you're just trying to map out her career, just know that at 25, Kim Chaewon is just getting started. The "Fearless" era isn't a fluke; it's a blueprint.
