Kelly showed that there exist planar posets of arbitrarily large dimension, and Streib and Trotter showed that the dimension of a poset with a planar cover graph is bounded in terms of its height. Here we continue the study of conditions that bound the dimension of posets with planar cover graphs. We show that ifis a poset with a planar comparability graph, then the dimension ofis at most four. We also show that ifhas an outerplanar cover graph, then the dimension ofis at most four. Finally, ifhas an outerplanar cover graph and the height ofis two, then the dimension ofis at most three. These three inequalities are all best possible.
