1. A driver-type golf club head comprising:
a volume greater than approximately 400 cc;
a face comprising:
a thickness;
a striking surface comprising an outer edge, where the outer edge defines a perimeter of the striking surface;
a back surface opposite the striking surface;
a perimeter region comprising a constant perimeter thickness, and extending inward from the outer edge of the striking surface toward a perimeter boundary, where the perimeter boundary defines the locations on the face where the thickness of the face deviates from the constant perimeter thickness;
a transition region comprising a varying transition thickness and extending inward from the perimeter boundary toward a transition boundary, where the transition boundary defines the locations on the face where the thickness of the face deviates from the varying transition thickness;
an intermediate region comprising a constant intermediate thickness and extending inward from the transition boundary toward an intermediate boundary, where the intermediate boundary defines the locations on the face where the thickness of the face deviates from the constant intermediate thickness;
an elliptical central region encompassing a geometric center of the face, the elliptical central region comprising a varying central thickness and extending inward from the intermediate boundary toward the geometric center of the elliptical central region;
wherein:
the constant intermediate thickness comprises a minimum thickness of the face;
the varying central thickness comprises a maximum thickness of the face;
the constant perimeter thickness is greater than the constant intermediate thickness and less than the varying central thickness;
a perimeter distance measured from the outer edge of the striking surface to the perimeter boundary is less than or equal to 0.25 inch.
