Claim:
Method for determining the length of the shaft of an individually adapted golf club, wherein the length ( 11 ) form the floor to the ankle, the length ( 12 ) from the ankle to the knee, the length ( 13 ) from the knee to the hip, the length ( 14 ) from the hip to the shoulder and the length ( 15 ) from the shoulder to the root of the middle finger of the right arm, which lengths are decisive for the height position of a golfers hands above the floor in the address position and during golf swing, are measured and the length (L) of a first shaft piece up to a second shaft piece or end piece (L 1 ) is calculated by the measured lengths and predetermined angles (A,B,C,D) between adjacent body parts corresponding to said lengths ( 11 - 15 ), as well as a predetermined angle (E) between the arms and the shaft or a predetermined lie angle (Î± 7 ) and wherein the respective lengths are measured while the golfer is standing upright, and the length measurement from the hip to the shoulder ( 14 ) is multiplied with a given correction factor to compensate for the curvature of the spine when the address position is taken.
