One of the books I got from Amazon was the Bleach Souls Official Character Book. As with most anime/manga character books, the height/weight ratios are
utterly fucking ridiculous. A few examples:
Matsumoto Rangiku - 5'6", 126 lbs
Ayasegawa Yumichika - 5'5", 123 lbs
Kuchiki Rukia - 4'7", 73 lbs
And the worst* offender of all ...
Zaraki Kenpachi - 6'6",
198 lbs.
(ETA: Before giving me 34523543 examples of people this tall and skinny [my dad's stepmother's side of my family is all over 6' tall. I am aware of how skinny a tall person can be], plz to be looking at the picture first and then decide if it's possible for someone to be drawn that big and be less than 200 pounds. I'm not saying that people can't be that height/weight, I'm saying Kenpachi can't be that height/weight. Also, the above people are all, essentially, elite athletes, so their weights should skew high. Although I bet Yumichika lied abut his.)--
* I don't consider Matsumoto to be an especially bad example, simply because knowing the Gotei 13's bizarre R&D department, it's entirely possible they're special implants filled with helium.
