text: is 155cm 2 short for a 16 yr old guy?   it is below average height for caucasians in western countries. is it too short? there's not a lot that can be done about it so no, i wouldn't worry about it. some people (who i think are possibly insane) have their legs broken and spend months with external fixators applying traction to leave them with weakend bone, long scars, lots of pain and an increase in height of a few inches. and in case anyone suggests it growth hormone is not indicated for short stature.   height may be indicative of other problems (rarely) - compare yourself to your parents' height to see if it is normal for you.
