Abstract: Methods of forming a golf club head having improved aerodynamic characteristics are disclosed herein. A preferred method is the largest tangent circle method, which utilizes a Cartesian coordinate system. The method results in identification and measurement of certain club head features, which can be adjusted to improve aerodynamic properties of the golf club head. One method of the present invention lowers the drag of the club head by specifying dimensional relationships of the driver head based on location of apex and nadir points, while another method lowers the drag of the club head by improving overall face design.
