How about this. It is the highest volume to aluminum ratio for a cylinder given a set volume and minimum wall stiffness. If you make the can shorter and fatter, you take the bend out of the wall and make the can more flimsy, requiring a thicker can to maintain stiffness. The answer is likely just good size for the hand, but thought I'd throw another angle out.
