Criteria for an analytic function f defined in |z| < 1 to belong to B0, the class of Bloch functions satisfying , and criteria for a meromorphic function g defined in |z| < 1 to belong to N0, namely, to satisfy are obtained in terms of the area and the length of the images of hyperbolic disks and hyperbolic circles, respectively.
