>>44359441Biologically speaking this might actually be the case, as it's plausible the Pokedex is accounting for "minimum" rather than maximum sizes.
Not defending OP here bc I just think the Pokedex is accounting for length/height depending on the shape of the species. Furret when stretched out is longer than Charizard's height, but Char's own length and wingspan would be different compared to its official "height."
GF should have clarified and separated these classifications in the Pokedex.
