IVE members' heights

IVE's heights: a tall group by any standard

IVE is a six-member South Korean girl group formed by Starship Entertainment, made up of Gaeul, An Yujin, Rei, Jang Wonyoung, Liz and Leeseo, according to Wikipedia. Four of the six have a sourced height in this site's data, and they are tall: Wonyoung and Yujin at 173 cm (5′8″), Liz at 171 cm (5′7½″) and Leeseo at 165 cm (5′5″). Those four average about 170.5 cm (5′7″), the highest of any girl group featured on this site.

If the Kprofiles figures for Rei and Gaeul are included, the six-member average is about 169.3 cm (5′6½″), still well above the norm for Korean women.

Where IVE heights come from

Like most K-pop agencies, Starship does not publish a measured height chart. The numbers on this page come from two layers of sourcing.

This site's figures are taken from Wikidata. For Leeseo, the Wikidata statement cites a specific YouTube broadcast as its reference; for Wonyoung, Yujin and Liz, the statements carry no reference at all, which is worth knowing when weighing them. Gaeul and Rei have no height statement on Wikidata, which is why they are missing from the site's chart.

The fan-run profile site Kprofiles fills the gaps and records where several figures came from. Its notes say that Rei confirmed she is 170 cm, Yujin confirmed 173 cm, Liz said she is around 171–172 cm and Leeseo confirmed 165 cm, each linked to a broadcast or post. Kprofiles is a fan compilation rather than an official source, but for these four members the figures come from the members' own statements, and they agree with the site's numbers wherever both exist.

The two 173 cm members: Wonyoung and Yujin

The tallest members of IVE are also its two most experienced. Wikipedia records that Jang Wonyoung and An Yujin, representing Starship, competed on the reality survival show Produce 48 in 2018, finishing first and fifth. That earned both places in the project girl group IZ*ONE, with which they promoted until it disbanded on April 29, 2021. Seven months later, on December 1, 2021, they debuted again as part of IVE.

At 173 cm, both stand about 11 cm above the 2022 average for Korean women aged 20 to 69. Yujin is the group's leader, according to Wikipedia's member list; Kprofiles lists her positions as leader, main vocalist and main dancer, a role it says was confirmed on the variety show Earth Arcade.

IZ*ONE produced members for two of the groups on this site. Kim Chaewon and Sakura Miyawaki, who also came out of Produce 48, are now in LE SSERAFIM, at 164 cm and 163 cm on this site. Wonyoung and Yujin are each about 9–10 cm taller than their former groupmates.

Liz and Rei: the 170 cm middle

Liz, born in 2004, joined Starship through an open audition in 2019, according to Wikipedia. This site lists her at 171 cm, and Kprofiles reports her own description of her height as "around 171–172 cm," so the site's figure is at the lower end of her statement. Kprofiles lists her as a main vocalist, a position it says is confirmed on her official Melon profile.

Rei, also born in 2004, is IVE's Japanese member. Wikipedia says she joined Starship in 2018 after passing the Loen Friends Global Audition in Japan, where her distinctive voice caught the judges' attention, and moved to Korea that May to train. Her height of 170 cm, which Kprofiles says she confirmed herself, is not yet in this site's data. It places her about 12 cm above the average Japanese woman born in 1996, who stands 158.3 cm in NCD-RisC data on our Japan average height page.

Leeseo and Gaeul: the youngest and the eldest

Leeseo, born in February 2007, is the group's youngest member. She was 14 when IVE debuted in December 2021. Wikipedia notes that she had earlier been an SM Entertainment Kids model. This site lists her at 165 cm (5′5″), which Kprofiles says she confirmed, and which is cited on Wikidata to a YouTube broadcast.

Gaeul, born in 2002, is the eldest. Wikipedia says she joined Starship in 2017 after being scouted at a dance competition in Incheon. Kprofiles lists her at 164 cm (5′4½″), which would make her the shortest member, 9 cm below Wonyoung and Yujin. She is not yet on this site's chart because no sourced height is recorded for her on Wikidata.

From Eleven to world tours: IVE's career in brief

IVE's rise was unusually fast. Wikipedia records that Starship announced the group on November 2, 2021, its first new girl group since WJSN in 2016, and revealed the members one by one from November 3 to 8. The debut single album Eleven followed on December 1, and exactly one week later IVE won their first music show, on Show Champion, the fastest win for a girl group since debut. "Eleven" went on to win 13 music show trophies.

The group's name is meant to evoke the English phrase "I have," expressing confidence in showing what the members already have, according to Wikipedia. Their second single album, Love Dive (2022), gave them their first number-one song on the Circle Digital Chart and won Song of the Year at the MAMA Awards, Melon Music Awards and Golden Disc Awards. IVE made their Japanese debut on October 19, 2022, and their English-language debut on January 19, 2024, according to Kprofiles, and Wikipedia notes performances at Lollapalooza in 2024 and at the Berlin and Paris editions in 2025.

IVE on international stages

Because IVE perform regularly in Japan, Europe and the United States, it is useful to compare the members with women in those audiences, using this site's NCD-RisC country data for women born in 1996.

Even among Dutch women, among the tallest in the world, Wonyoung and Yujin would stand above average. In the United States, the group's four listed members average 7 cm more than the typical American woman, based on the NCD-RisC figure of 163.5 cm for American women born in 1996.

How IVE compare with Korean women

The IVE members were born between 2002 and 2007, a generation that grew up after the largest height increase recorded anywhere in the world over the past century.

The NCD Risk Factor Collaboration's study, published in eLife in 2016, found that South Korean women gained about 20 cm in average height over the 20th century, the largest increase of any population of either sex, moving from the fifth-shortest women in the world to the top third. A separate Seoul National University study reported by The Korea Herald estimated the average Joseon-era Korean woman, from the 15th to 19th centuries, at 148.9 cm.

Against the NCD-RisC figure for women born in 1996, shown on our South Korea average height page, the listed IVE members average about 8 cm taller. Wonyoung and Yujin are almost 11 cm above it. Even Gaeul, at Kprofiles' 164 cm, is above the national average for her generation.

The Korea Herald's report on the government's 2023 youth measurements shows that girls are still getting slightly taller: female high school students averaged 161.7 cm in 2023, up from 159.8 cm a decade earlier. IVE's members belong to that cohort.

How to read idol height figures

The IVE numbers illustrate a few general rules for interpreting K-pop heights.

• Self-reported figures are usually whole centimeters. Rei's 170 cm, Yujin's 173 cm and Leeseo's 165 cm are all round numbers, and Liz gave a range rather than a single value. Differences of one centimeter between sources should not be read as real changes.
• Missing is not the same as unknown. Gaeul and Rei are absent from this site's chart only because no sourced height has been added to their Wikidata entries yet, not because their heights have never been mentioned. When a sourced figure is added, they will appear automatically.
• Unreferenced entries deserve more caution. On Wikidata, the heights for Wonyoung, Yujin and Liz have no reference attached, while Leeseo's points to a specific broadcast. The member statements recorded by Kprofiles help corroborate the unreferenced values.

If you want to check a particular comparison yourself, the height difference calculator gives the exact gap between any two heights in centimeters and feet.

IVE among the featured girl groups

Among the four K-pop groups with their own pages on this site, IVE has the tallest average and the widest spread among its listed members, 8 cm from Leeseo to Wonyoung and Yujin.

aespa is the only one of the three with all members listed. In feet and inches, IVE's tallest members at 173 cm are 5′8″; the 173 cm conversion page shows how that compares with women in the United States and worldwide.
