Wonyoung Height: How Tall Is the IVE Star? Height, Weight and Sister
Amid the crowded K-pop performance stage, Wonyoung Jang is an easy one to recognize. Part of the reason is that she is exceptionally tall. How tall is Wonyoung, exactly?
It has been widely reported that Wonyoung’s height is 173 centimeters, or about five feet eight inches. However, there’s some nuance behind that number worth understanding, as of September 2, 2026.
Featured Snippet Answer
Wonyoung’s commonly listed height is 173 cm, or about 5 feet 8 inches. She is considered one of the tallest members of IVE, close in height to fellow member An Yujin, though exact database figures vary slightly.
Who Is Jang Wonyoung?
Before IVE, there was Produce 48. Jang Wonyoung competed on the Mnet program in 2018 and ranked first, becoming part of the group IZ*ONE. She was just a teen, but fame came quickly.
Wonyoung’s Profile and Rise to Fame
IZ*ONE’s activities concluded in 2021. But then the next chapter began. On December 1, 2021, Wonyoung returned to Starship Entertainment and debuted under the name IVE with the single album Eleven.
Wonyoung Height: How Tall Is Wonyoung?
It is commonly stated that Wonyoung’s height is 173 cm. In inches, 173 cm translates to roughly 68.1 inches, which comes out to five feet eight inches.
Wonyoung Height in Feet and Centimeters
The math checks out: a Wonyoung height of 173 cm equates to 1.73 meters and roughly 5 feet 8.1 inches. Most English-language biographies simply round this to 5 feet 8 inches. Claims that she looks “taller” generally come from photos rather than precise measurements.
Wonyoung Height and Weight
This is where things get less clear. Entertainment databases typically list her weight at around 47 kg, or 104 lb, but Starship Entertainment does not consistently confirm an up-to-date official figure. People change, so this number should be treated as unconfirmed rather than fact.
How Wonyoung’s Height Compares With Other IVE Members
Place Wonyoung beside the other IVE members and she clearly stands among the tallest. Published profiles often put her close to An Yujin, though exact measurements vary from one database to another. Is she the sole tallest member? Not always — the safest description is joint-tallest, or simply one of IVE’s tallest members.
Wonyoung’s Career With IVE
IVE did not arrive quietly. Eleven made an immediate impact, followed by widely recognized releases such as Love Dive, After LIKE and I AM. Wonyoung’s camera awareness and elegant performance style suited the group’s confident image. Outside of music, fashion shoots, campaigns and hosting work have kept her firmly in view.
How Jang Wonyoung Became an IVE Member
Her place in IVE was not an overnight jump. Produce 48 offered her national exposure, while IZ*ONE gave her stage experience. When Starship launched its new six-member group, she was ready to debut — a new beginning, not just another comeback.
Wonyoung’s Sister and Family Background
Offstage, her family is far less prominent. Wonyoung’s elder sister, Jang Da-ah, is an actress, while her parents stay out of the spotlight for the most part. Information about the extended family is hard to come by, and that boundary deserves respect.
Who Is Wonyoung’s Sister?
Jang Da-ah chose a different lane. Represented by King Kong by Starship, she made her acting debut in the 2024 series Pyramid Game. Her role as Baek Ha-rin was controlled, cold and memorable. The family connection drew early attention, but Da-ah is steadily building an identity of her own.
Why Wonyoung’s Height Attracts So Much Attention
A single stage photo can make the Wonyoung height debate flare up again. Yet height is only part of the picture. Long proportions, fitted styling, heeled footwear and confident posture can all make her appear taller, and group formations add another trick, since members may stand at different depths on stage.
The fascination makes sense. Fans often use profile details as a quick introduction to an artist. But one measurement says nothing about talent, health or success — it’s a detail, not the whole story.
