Ok, according to the
http://www.easyheight.com/shin.htm page, if you scroll down you'll see all the info about the memebers; including their heights. It cleary states that King is 5'7 and Licong is 5'4, but it also states that Ryan is
JUST UNDER 5'6. So, this means that he could only be at 5'5.5(167cm) or 167.5cm's tall.
But yeah, it does look like Ryan is 5'5 tall, because there should only be a 2cm gap (168-170) between Him and King!
