a head depth plane extends through the strikeface centerpoint, parallel to the head horizontal axis and perpendicular to the loft plane;
a CG height axis extends through the head center of gravity and intersects the head depth plane perpendicularly at a first intersection point;
a head CG height of the head center of gravity is measured, along the CG height axis, between the head center of gravity and the first intersection point;
a head CG depth of the head center of gravity is measured, parallel to the ground plane and orthogonal to the front plane, between;
a second intersection point located at an intersection between the front plane and the ground plane; and
a third intersection point located at an intersection between the head vertical axis and the ground plane;
the head CG depth is approximately 25 mm to approximately 102 mm;
the face height is approximately 33 mm to approximately 71 mm, measured parallel to the loft plane;
a weight center elevation axis extends between the weight center and the ground plane, being orthogonal to the ground plane when the golf club head is at the address position;
a head CG elevation is measured, along the head vertical axis, between the head center of gravity and the ground plane;
a weight center elevation is measured, along the weight center elevation axis, between the headcenter of gravity and the ground plane; and
a weight center depth of the weight center is measured, parallel to the ground plane, between;
the second intersection point at the intersection between the front plane and the ground plane; and
a fourth intersection point at an intersection between the weight center elevation axis and the ground plane; and
a depth ratio, defined by the weight center depth over the head CG depth, is less than 2.54;
and an elevation ratio, defined by the weight center elevation over the head CG elevation, is greater than 0.44.
