IU, who is frequently regarded as one of Korea’s most adored performers, has never hesitated to challenge popular perceptions. She did something that few celebrities dare to do on a memorable 2012 episode of the talk show Strong Heart: she stepped on a scale in real time to reveal her actual height and weight. In a society that frequently puts idols under tremendous pressure to meet idealized physical standards, it was an unvarnished moment. Her height of 161.7 centimeters and weight of 44.9 kilograms were remarkably in line with the public estimates that fans had conjectured about for years.
This gesture was a statement rather than a publicity gimmick. IU provided evidence rather than assurances during a period when internet rumors circulated that she appeared “elementary school-sized” or “starved.” She clarified that even when her weight was constant, her bone structure gave the appearance of being extremely thin. By doing this, she addressed criticism of herself as well as the entertainment industry’s general propensity to evaluate performers solely based on their body image.

In the last ten years, IU’s name has come to represent resiliency and creativity. Her development has been especially indicative of her inner maturity, from the tender ballads that characterized her early career to genre-bending chart-toppers like Palette and Eight. The same development can be seen in the way she has handled discussions about femininity, body image, and health.
Although people have long been drawn to her slim figure, IU has always responded to questions with a welcome level of openness. She has been candid about her past battles with bulimia, which has helped to humanize the K-pop image that is so frequently pristine. She gave many young fans the opportunity to feel seen—and perhaps more importantly, not alone—by admitting that her journey hasn’t always been perfect.
Comparing K-pop idols is a common practice among fans. Additionally, IU’s peers’ heights and weights—such as Sulli, Lee Jong Suk, or Bae Suzy—are mentioned in the same sentence as her own. Even though these discussions frequently center on numbers, IU’s case offers a more insightful lesson. She is defined by how she owns her stats, not by them. Although she is 161.7 cm tall, her character, artistic ability, and unflinching poise in the spotlight are more impressive.
Because her revelation occurred at a time when body-shaming was much less contested, it had a particularly powerful effect. IU quietly changed the discourse by willingly disclosing private information on a national broadcast, demonstrating that vulnerability can be incredibly empowering in addition to demonstrating that honesty and celebrity can coexist.
The charming, young “Nation’s Little Sister” has given way to a self-assured, multifaceted artist in recent years. Her personal development and her attempt to regain control over her story are reflected in that change, which goes beyond a simple rebranding. She seems to be reiterating a subtle but obvious message with every performance and public appearance: success and beauty are not universal.
The high expectations Korean entertainment, and especially idol culture, places on its stars are often criticized. But things are starting to change—slowly, steadily, and remarkably, thanks to people like IU. Such courageous disclosures have contributed to the industry’s growing awareness of mental health issues and more diverse body representation. IU made it possible for others to talk openly about their weight without feeling ashamed or afraid by doing so herself.
Fans have also seen a more realistic and open side of her through her relationship with another well-known celebrity, actor Lee Jong Suk. Both are very well-liked and frequently watched by the public. However, they have maintained a relationship based on respect for one another rather than on showbiz extravaganza. The dynamic of their relationship quietly highlights IU’s well-rounded approach to celebrity, which puts authenticity above appearances.
IU has prioritized wellness over appearance in recent advertising campaigns. She has shown time and time again that being a public figure can coexist with being a force for good, whether through her skincare endorsements or charitable endeavors. For example, she influenced the brands she collaborated with to donate thousands of items to the cause during her 13th debut anniversary, in addition to donating over $700,000 USD to underprivileged communities.
IU has been incredibly transparent about her identity and values throughout her journey. Such clarity is especially helpful in a media environment that is frequently rife with false information and inflated stories. She usually speaks with purpose; she never aims for sensationalism and always seeks to connect.
