text: what is proper weight for male 6'3" tall?   it depends totally on your bone structure and your muscle mass  best to get your skinfolds done - you are healthy if you are below 17% bodyfat   a small boned  man might weigh around 170 lbs at this height, a big boned man maybe 250 lbs - both at the same bodyfat!  i am a bit taller than 6'3" and i weigh 260 lbs but i am quite big boned and have a lot of muscle - i am 8% bodyfat  bmi are a waste of time - they dont take into account either bone density or muscle mass so stick to bodyfat as your guide to a healthy weight
