The rookie idol, part of BigHit Music’s new boy group CORTIS, recently responded to a fan’s question on Weverse asking, “Martin, how tall are you?” His reply: “6’3” —accompanied by a dancing emoji.”
The simple yet revealing comment confirmed that Martin stands at 6 feet 3 inches (over 190 cm), making him one of the tallest idols in the industry.


Netizens React: “A Giant Baby”
Following his confirmation, netizens flooded forums with amused and awestruck reactions. Popular comments included:

- “ㅋㅋㅋㅋ ㄷㄷㄷ so tall…. I’m curious what the air is like up there. I’m 167 and my guy friend is 190, and even then when I look up my neck feels like it’ll snap”
- “ㅋㅋ literally a giant baby”
- “Is he the tallest among male idols?”
- “If they measured again, he might be even taller”
- “He really did look over 190 lol. The other members seem mid-170s, judging by the difference lol. For real, a giant baby”
- “So big… and he is only eighteen years old? He’ll grow even more”
Photos from CORTIS‘s recent performances and music video also resurfaced, with many fans noticing just how visibly taller Martin appears next to the other members—who are estimated to be in the mid-to-high 170s cm range.
Rising Star Born in 2008
Martin, born in 2008, is not only the tallest member but also the leader of CORTIS. He holds dual Korean and Canadian citizenship and has quickly gained attention for his visuals, charisma, and international background.

Despite debuting just on August 18, Martin’s presence has already become a defining feature of the group. His height, combined with his age, has sparked even more curiosity about his growth potential and future in the industry.

Martin’s 6’3” stature has led fans to speculate whether he might currently be the tallest active male K-pop idol, with comparisons drawn to longtime tall entertainers like Lee Kwang Soo. As CORTIS continues to promote their debut, Martin’s height—and “giant baby” nickname—are quickly becoming an iconic part of the group’s identity.
