Let K R d be a convex body, and assume that L is a randomly rotated and shifted integer lattice. Let K L be the convex hull of the (random) points K L . The mean width W ( K L ) of K L is investigated. The asymptotic order of the mean width difference W ( λ K ) W ( ( λ K ) L ) is maximized by the order obtained by polytopes and minimized by the order for smooth convex sets as λ .
