New tight bounds are presented on the minimum length of planar straight line graphs connecting n given points in the plane and having convex faces. Specifically, we show that the convex Steiner partition of n points in the plane is at most O(log n/log log n) times longer than their Euclidean minimum spanning tree (EMST), and this bound is best possible. Without allowing Steiner points, the corresponding bound is known to be Θ(log n), attained for n points lying along a pseudo-triangle. We also show that the convex Steiner partition of n points along a pseudo-triangle is at most O(log log n) times longer than the EMST, and this bound is also best possible. Our methods are constructive and lead to polynomial-time algorithms for computing convex Steiner partitions within these bounds in both cases.
