Just wondering whether height, or class determines if you get a Small, Medium, or Large weapon/ mount.

Like Lalafell of course are all gonna get small mounts and weapons, and Midlanders, Miqos and Female Auri are gonna get medium-sized stuff, while Roes and Male Auri are gonna get the Large Mounts and weapons.

But I'm still unsure about Highlanders and Elezen, since their height can vary a bit, like can a small Highlander or Elezen get get the medium sized items while the tallest get the large versions, or is it all class-based and not height related at all?
