No, elves are generally shorter than most humans, in Forgotten Realms Lore at least (drows being the shortest).
About being stout, every Player character type is toned and lithe, so I see no reason for that comment (btw, all our current Player Character choices were inspired by and sculpted from the faces of real life models).
Honestly, I wish rpgs would present a bit more variety in body types. I really loved that about Obsidian's Tyranny, where you could choose height and body type (I do realize that Tyranny had a much more isometric cartoonish style where it was easier to implement such things).
