User Mega_Septile I am aware of the size differences in the anime as well. I believe the people who make the decisions about Pokémon are trying to make Pokémon as realistic as they can for a show/game about "magic animals". They are trying to base it off the animals in our world. I believe Pokémon, like animals, probably come in all sorts of different sizes, and the pokedex entries on height and weight are just rough ideas of the general size of Pokemon. I would think Crobat's body would be no bigger than 1.5 feet, but because of the Pokedex I know they run around 5 feet, so their may be Crobat's as small as 3 feet or as big as 6 feet, but the Pokedex just gives a point of reference, and is not the end all to Pokémon sizes, it probably isn't even an average size of the Pokémon. That is just my thoughts on the matter, just an opinion. :)
