How tall is Martin CORTIS?

Martin Cortis height in feet and centimeters

Martin’s height is one of the most frequently searched details about him — and also one of the least settled. Two different fan-aggregator profiles give conflicting numbers. Kpop Profiles (fan-run profile database) lists his height at 193.4 cm (6’4″), while Kpopping (K-pop fan wiki) reports 190.5 cm (6’3″).

“I’m 6’3.”

The catch

No official measurement from BigHit Music or a verified press release exists. Until the label publishes an official profile, fan-reported numbers — even those quoted by the artist in casual conversation — remain unverified.

Is Martin Cortis’s height known?

Not with certainty. The range between 190.5 cm and 193.4 cm is roughly a 3-centimeter gap, which is small enough that it could be measurement error, growth, or a rounding difference. For fans asking “How tall is Martin CORTIS?,” the honest answer is: around 6’3″ to 6’4″, with no official confirmation as of 2025.

The implication: the height question is a microcosm of the broader Martin Cortis research problem — fan-sourced data dominates, and primary sources are scarce.

How old is Martin from CORTIS?

Martin Cortis birthday and zodiac sign

Martin was born on March 20, 2008, making him 17 years old as of 2025. His birthday is confirmed by a Kpopofficial (fan-aggregator profile) and cross-referenced by his Instagram account (primary social media, @martin.cortis), which displays the date 2008.03.20 in its bio. His zodiac sign is Pisces.

At 17, he is one of the youngest group leaders in a major K-pop label’s recent history. Rolling Stone (music journalism outlet) specifically noted his age in its coverage of CORTIS’s debut, describing him as “the group’s leader at age 17.”

Why this matters

Leading a group at 17 is unusual even by K-pop standards, where group leaders are typically in their early 20s. Martin’s age highlights the trust BigHit Music placed in him after six years of training — and the pressure that comes with that responsibility.

The pattern: his birth date is one of the few data points with multiple independent sources (a fan profile, a social media account, and a major publication), making it among the most reliable facts in his biography.

What is Cortis Martin’s nationality?

Martin Cortis’s nationality and ethnicity

Martin is South Korean-Canadian. Rolling Stone (established music publication) describes him as Korean-Canadian, and Kpopping (K-pop profile aggregator) lists him as a Korean-Canadian singer, songwriter, rapper, and record producer under BigHit Music. His Instagram account (primary social media) also reflects this dual identity in his bio and content.

What this means: the “Korean-Canadian” label is consistently reported across multiple sources, but the specific split — which parent is Korean, which is Canadian — is only addressed by lower-confidence fan wikis. A CORTIS Wiki Fandom (user-generated fan wiki) claims Martin has a Canadian father and a Korean mother, but this is not corroborated by any official source.

What is the real name of Martin of CORTIS?

Martin Cortis’s full name

Martin’s birth name is Martin Edwards Park, according to the Wikipedia page for CORTIS (community-edited encyclopedia). A Kpop Profiles (fan-compiled member database) lists his stage name as Martin, his birth name as Martin Jonathan Edwards, and his Korean name as Park Woo-joo. The discrepancy between “Martin Edwards Park” and “Martin Jonathan Edwards” is notable — it may reflect a Western name order versus a formal legal name, but no official source has clarified which is correct.

The catch: the name “Martin Jonathan Edwards” appears on a fan profile, not a primary document. Until BigHit Music publishes an official artist biography, the exact full name remains in a gray area.

What is Martin from CORTIS mixed with?

Martin Cortis’s ethnic background

Martin is of mixed Korean and Canadian heritage. Rolling Stone (music journalism outlet) identifies him as Korean-Canadian, and Wikipedia (community-edited encyclopedia) notes his background without specifying the exact ethnic mix. The CORTIS Wiki Fandom (user-generated fan wiki) claims his father is Canadian and his mother is Korean, but this is a low-confidence claim.

A fan wiki also states that Martin was born in Songpa-gu, Seoul, South Korea, which would align with a Korean mother and a foreign father, but again, no official source confirms this.

The trade-off: the broad “Korean-Canadian” label is well-sourced, but the specific breakdown — and which parent contributed which nationality — is not yet on the record from BigHit Music or any primary interview.

What we know vs. what remains unclear

Confirmed facts

What’s unclear

  • Exact height — conflicting reports of 6’3″ and 6’4″
  • Father’s nationality and mother’s background
  • Sister’s age and details
  • Specific ethnic mix breakdown
  • Legal full name (Martin Edwards Park vs. Martin Jonathan Edwards)
  • Real name: Martin Edwards Park (unconfirmed, sourced from Wikipedia)
  • Debut date: August 18, 2025 (from Kpopping, tier3)
  • Pre-debut training: 6 years, starting 2019 (from CORTIS Wiki, low confidence)

Behind the music: Martin’s pre-debut story

Before leading CORTIS, Martin reportedly had an unusual pre-debut path. Wikipedia (community-edited encyclopedia) states he was a member of the Rainbow Children’s Choir and served as a flag bearer for Iceland at the 2018 Winter Olympics in PyeongChang. A CORTIS Wiki Fandom (user-generated fan wiki) claims he auditioned for BigHit Entertainment in 2019 while in fifth grade and trained for six years.

Martin also contributed to music production before his own debut. Rolling Stone (music journalism outlet) reports that he worked on ILLIT’s music, ENHYPEN’s “Outside,” and TXT’s “Beautiful Strangers.” Wikipedia (community-edited encyclopedia) adds that he contributed to ILLIT’s “Magnetic,” LE SSERAFIM’s “Pierrot,” and TXT songs including “Deja Vu,” “Miracle,” and “Beautiful Strangers.”

“[Martin] is the group’s leader at age 17, a Korean-Canadian singer, songwriter, rapper, and record producer.”

The pattern: Martin’s pre-debut credits span multiple HYBE sub-labels, suggesting he was a trainee with unusual creative freedom. For a 17-year-old to have production credits on songs by already-established groups like TXT and LE SSERAFIM signals a level of trust from the company that goes beyond the typical trainee experience.
