1. A putter-type golf club head that, when oriented in a reference position, comprises:
a striking surface having a face center;
a top surface extending rearwardly from the striking surface and including an alignment element having a pair of parallel edges spaced apart from each other by a distance that is substantially the same length as a golf ball diameter, each of the parallel edges extending generally perpendicularly to the striking surface and being laterally offset from the face center;
a club head volume no greater than 60 cc;
a length L and a width W such that L*W is greater than 14 in2; and
a mass between 300 g and 400 g,
wherein the alignment element includes a guide line that (i) is parallel to the parallel edges of the alignment element, (ii) originates from an edge of the alignment element closest to the striking surface and extends therefrom less than a length of the parallel edges, (iii) laterally bisects the alignment element into two portions that are connected to each other, and (iv) comprises a groove, and
wherein a moment of inertia Izz of the golf club head is no less than 3,500 g*cm2.
