Claim 13:
14. A putter-type golf club head comprising:
a body comprising:
a volume less than 50 cm3;
a strike face bounded by a strike face perimeter and comprising a geometric center, a loft plane, a strike face surface area ASF, a leading edge, a top edge, and an apex located at a center of the top edge;
wherein the strike face further defines a CG projection point where a projection of the center of gravity (CG) is normal to a loft plane onto the strike face;

a heel end, a toe end, a crown, a sole, and a rear end opposite the strike face;
an origin point located at a center of the leading edge;
wherein the strike face comprises a strike face width WSF measured across the strike face in a heel end-toe end direction;
wherein the strike face perimeter comprises a multi-sided shape having a high-heel corner, a low-heel corner, a high-toe corner, and a low-toe corner;
wherein the putter-type golf club head defines an apex angle α1 measured between a first reference line connecting the apex and the low-heel corner and a second reference line connecting the apex and the low-toe corner of the strike face;
wherein the apex angle α1 is between 80 degrees and 90 degrees:
wherein the putter-type golf club head further defines a center of gravity (CG) angle α2 measured between a first reference line connecting the CG projection point and the low-heel corner and a second reference line connecting the CG projection point and the low-toe corner;
wherein the center of gravity (CG) angle α2 is between 115 degrees and 130 degrees;

a first portion and a second portion, wherein the first portion comprises the strike face, and a transition region, and the second portion is positioned rearward from the first portion and comprises a remainder of the body;
wherein the transition region comprises a first transition wall and a second transition wall, and wherein the first and second transition walls extend from the strike face to connect the strike face to the second portion;

wherein the body further comprises a body width WB less than 2.30 inches, the body width WB measured between the heel end and the toe end in the heel end-toe end direction;
wherein the body further comprises a body depth DB less than 2.50 inches, the body depth DB measured between the strike face and the rear end in a strike face-rear end direction; and
wherein a ratio WSF/WB of the strike face width WSF to the body width WB is less than 0.75.
