>>12743403Size, when measuring an animal, is typically the dimension of the animal's size that is the largest. For a snake(see arbok, who is eleven and a half feet long, according to the pokédex), you lay it out and measure it from the tip of its nose to the tip of its tail. For a quadruped, the measurement is, typically, to the shoulder.
Insects are measured by body-length. Also, do you even foreshortening? It's sitting at an angle, with its back end further from perspective than its front end so of course it looks small.
