This site sucks. People who share the same height and weight can still look radically different depending on a variety of factors:
- how much of their weight is muscle as opposed to fat (a 5'10" 200 pound bodybuilder with 6% body fat is going to look really different than a 5'10" 200 pound office worker at 32% bodyfat).
- their posture
- whether they are ectomorphic, endomorphic, mesomorphic
- their bone structure (wide hips vs narrow hips / broad shoulder vs thin shoulders)
...etc.
Moreover, a lot of these people are wearing ill fitting clothes that don't give the viewer an accurate glimpse of what their body looks like. I mean, what the hell am I supposed to glean from looking at this guy:
Other than the fact he dresses like shit at the beach, I can't tell anything about his height and weight because he's all bundled up. Like I said, this site sucks. And BMI is antiquated.
