Stray Kids Members: A Practical Age Reference
The most common question I see when people get into Stray Kids is the age ordering among the eight members. It matters because the group's dynamics, unit assignments, and even how fans talk about seniority all hinge on who is oldest and who is youngest. Below is the straightforward breakdown. I am going to give you birthdates and note that you should calculate ages yourself depending on when you are reading this, since the numbers shift every year. Bang Chan — born October 3, 1997. He is the oldest member and serves as the group's leader. In Korean age reckoning he would be four to five years ahead of the youngest member depending on the calendar year. For international fan contexts, his Western age is what most non-Korean sources use. Lee Know — born January 25, 1998. He is the second oldest. Fans sometimes call him the "dance main" because his performance background shows in every routine. His birthday falls in the early part of the year, which keeps him ahead of nearly everyone else except Chan.
Changbin — born August 11, 1999. Third in seniority. He handles a lot of the group's rap composition work. If you are looking at when he turned 25 or 26, check the calendar: his birthday is in late summer, so for most of any given year he has not yet reached that milestone. Felix — born September 15, 2000. Australian member. Sometimes people get confused about whether he is older or younger than Hyunjin because their birthdays are close, but Felix is definitively younger by a few days compared to Hyunjin's March birthdate. His deep voice is something new fans comment on constantly. Hyunjin — born March 20, 2000. He is actually older than Felix, Changbin, Seungmin, Han, and I.N. This is a detail that trips up some casual fans who assume alphabetical or lineup order matches age order. Hyunjin is the visual and a main dancer.
Seungmin — born September 22, 2000. Close in age to Felix, just one week younger. He is the main vocalist. The September birthday cluster in this group is real: three members born in September across different years. Han — born September 14, 2001. One of the two youngest. His birthday is exactly one day before Felix's, which means in any given September the birthday celebrations for Han and Felix happen back to back. Han is a main rapper and also involved heavily in production. I.N — born February 8, 2002. The youngest member and the only one born in the 2000s decade among the current lineup. He joined as a trainee after winning a casting contest. Being the youngest affects how the older members interact with him, and it shows in variety content where he is often the one being teased or protected.
Get the Full Details
Here is the full ranking from oldest to youngest by Western age: Bang Chan (1997), Lee Know (1998), Changbin (1999), Hyunjin (2000, March), Felix (2000, September), Seungmin (2000, September), Han (2001), I.N (2002). One thing that comes up repeatedly and causes genuine confusion: Korean age versus international age. In Korea, you are one at birth and gain a year on New Year's Day, not on your birthday. That means a Korean source might list Bang Chan as two years older than his Western birthday suggests. When I was compiling member info for a fan project a while back, I ran into a situation where two different databases listed the same member with ages that differed by three years. The fix was simple but annoying: I stopped using any sourced "current age" field entirely and switched to listing only birthdates. Birthdates do not change. Ages do. This cut my revision workload from something like eight hours down to maybe forty-five minutes because I never had to update numbers again. Another practical issue people miss: the group has nine original members, but Han was the last to join before debut, and later Chenle and another member left. The current active lineup is eight. Some older merchandise or early content references nine, and if you are tracking member ages across the group's entire timeline, you need to account for who was present at which point. The ages above apply to the current eight-member configuration only.
For the latest official information, the best source is JYP Entertainment's website or the group's verified social media channels. Fan wikis are useful but they can lag behind, especially when members have birthdays in the current month. If you need precise ages for a specific date, calculate from the birthdate yourself rather than trusting a static number you found online. I have seen too many articles copy-paste ages from a post written six months earlier, which means the numbers are already wrong by the time you read them. There is no downloadable file or single definitive spreadsheet that stays current. What exists are individual member profiles on the official Stray Kids site, and those list birthdates, not ages. I recommend bookmarking the official page instead of hunting for a compiled list that will go stale. The birthdate approach is the only method that does not require constant updates.
