Kim DaMi is 170cm which is considered tall in Korean standard. Have a look at some of her pictures below.
Since Park SeoJoon is 185cm and Kwon NaRa is 170cm, her height did not appear to be tall in "Itaewon Class".
Netizens commented: "I did not know she is 170cm tall", "She is tall", "What?!", "She is 170cm?", etc.
Did you notice she is 170cm?
