I'd wager that if you took a sample of fantasy world maps from DeviantArt or any other place that maybe one out of one hundred would fit an actual Earth-like size comparison. As for the sizes used in this, it's really simple: I got a sketch by the original client for the relative positions of the land masses, which includes Multania. Multania is ~900 miles from East to West. The rest is based on that distance. *shrugs* As for the none-existant distortion, I'll be frank and say that I couldn't care less about that. I have yet to come across a single client who actually wants something like that factored in, and not factoring it in allows for a far smoother creation process with easier perspectives and better means to portray most of the stuff a client might want.
