For a set P ⊆ R2 with 2 ≤ n = |P | < ∞ we prove that mst(P ) bb(P ) ≤ 1 √2 √ n + 32 where mst(P ) is the minimum total length of a rectilinear spanning tree for P and bb(P ) is half the perimeter of the bounding box of P . Since the constant 1 √ 2 in the above bound is best-possible, this result settles a problem that was mentioned by Brenner and Vygen (Networks 38 (2001), 126-139).
