I guess it becomes apparent how much Tolkien I've read, when I start talking about relative heights. . .
Well, we know that elcari are smaller than uesti, and flaids are bigger, and illi are bigger still, but are Almean uesti on average shorter, taller or the same size to the Terrestrial equivalent (I don't necessarily want exact measurements. . .)?
There is difference among ethnic groups, as well, aren't there? As I recall, southerners are taller than plain-dwellers, for example.
Almean and terrestrial humans are within each other's range of height variation. In practice, that means that things like nutrition are more important than the planetary difference. Verdurians on the whole would be shorter than Americans, because they're not as well fed.
They?d also be thinner than most Americans Please have the person who tries to invent fast food be a wizard, who then finds his spell makes him suddenly grow fatter and fatter until he finally explodes in public and be such an awful warning that it puts everyone off the idea
