  Let $\operatorname{pd}(I(G))$ and $\operatorname{reg}(I(G))$ respectively
denote the projective dimension and the regularity of the edge ideal $I(G)$ of
a graph $G$. For any positive integer $n$, we determine all pairs
$(\operatorname{pd}(I(G)),\, \operatorname{reg}(I(G)))$ as $G$ ranges over all
connected bipartite graphs on $n$ vertices.
