If you think you can tell an idol’s height just by watching them on stage, think again. These five stars have been shocking netizens—despite their powerful energy and lithe proportions, they’re all 160cm tall (5 feet and 3 inches) or less.

1. Irene (Red Velvet)

As Red Velvet’s Irene is known for her small figure and even smaller face.

She may look like she has a runway model’s proportions, but her official height is 160cm and her estimated real height is just 157cm (5 feet 2 inches).

2. Wendy (Red Velvet)

And Irene isn’t the only Red Velvet member whose height surprises people. Considering how incredible her singing is, you may think her size would reflect her vocal power.

However, her real height has been estimated at 155cm (5 feet 1 inch). That said, since her accident, Wendy revealed she’s grown 2cm taller.

3. Eunbi (IZ*ONE)

IZ*ONE’s maknae Wonyoung is the tallest member of the group, so perhaps it’s not all that surprising that oldest member Eunbi is one of the shortest.

Despite boasting a figure that appears tall, tiny leader Eunbi’s official height is 160cm. More surprisingly, fans have estimated that her real height could be just 158cm (5 feet 2 inches).

4. Dahyun (TWICE)

TWICE’s Dahyun has lithe, fairy-like proportions that match her pure and innocent beauty, but netizens are often surprised when they learn how tall she is.

At 159cm (5 feet 3 inches) tall, Dahyun is believed to be the shortest member of TWICE these days.

5. Soyeon (G)I-DLE

(G)I-DLE’s Soyeon radiates charisma and raps with so much force, you’d be forgiven for thinking she’s taller than she is.

The fiery leader is just 157cm (5 feet 2 inches) tall, making her the shortest member of the group by a 4cm margin.
