RIIZE member Wonbin's short stature became a hot topic on online communities.

On December 18, a post with the title 'RIIZE Wonbin's height becomes a controversy causing a buzz' was created on a popular online community, Nate Pann. The post included various short clips and photos showing RIIZE members performing.

The post's creator pointed out the distinct height difference between the members and Wonbin while explaining, "I think height is important in male idols. He doesn't look cool whatever he does. He's definitely not 175cm (5'9"). Maybe he's 170cm (5'7") at best."

This online community post gained attention from Korean netizens as they joined the discussion on whether height is important for male idols or not.

They commented, "I think body proportion is the bigger issue, not height," "I think he's losing his viral popularity now," "He's short, his body proportion isn't that good, his face is ordinary. Why is he the center?" "I think face is more important than height in guys!" "He's so good-looking and popular so people are making posts like this," "I think he's cute and it's good to see him putting in so much effort," "Sungchan is almost 190cm so it's not fair to compare him to Sungchan's height," "He's definitely 168-170cm," "Aren't the female idols wearing heels?" "I think he's good-looking, so it's fine," and "I think Wonbin would be around 172-173cm. He just looks short compared to Sungchan who is over 185cm."
