According to the Wario World instruction manual, Wario weighs 308 pounds (140 kilograms), although he declares it's just his clothes ("I like to layer!"). He has broad, muscular arms, a large belly, and his excess fat overlaps the openings of his overalls; it is shown his arms and legs are pure muscle meaning the rest of his fat must be stored elsewhere.
His skin ranges from a fair to tan complexion. The tone is similar to that of the other men'. His nose is pink, large, slightly pointed down, and he has large nostrils. Wario's mouth is square, as is his head, with blocky teeth and a fixed grin. He also has a round, thick, cleft chin. He has round black-eyes shaped by his cheeks and arched brows. They are outlined with a light blue, baggy, ring similar to Waluigi's. He has very constricted pupils and his iris is of a very dark shade.
Wario is actually not as short as he appears. He appears much wider than others and he's noticeably taller than Mario. In fact, Wario is as tall as Luigi regardless of his stout appearance, but he is still shorter than others such as Peach and Waluigi. His athletic abilities tend to make him a powerhouse character, as is expected with his body type.
Wario has light brown hair, the same color as Waluigi's. His hairstyle is the same as Waluigi's as well, having small flips at the back, swooped up bangs, and styled sideburns. He also has a black, zigzag shaped mustache which is a unique trait.
