- 7. A method for prescribing overall club length for iron-type golf clubs for an individual player, said method comprising:
measuring the erect height (PH) of a player to be fitted; providing the player with a fitting ball club (FBC) comprising:
a spherical ball having a hosel bore therein, a golf club shaft one end of which is in said hosel bore and connected to said spherical ball, and a golf club grip on the other end of said shaft; having the player hold the fitting ball club in address position as if about to hit a golf ball therewith; measuring the wrist-to-floor measurement (WFM) vertically from the player's higher wrist to the floor therebelow; locating data in the first two columns of the table of FIG. 4, said data corresponding to the PH and WFM measurements, respectively, for the player; deriving an incremental length LCC from the third, length control club column of FIG. 4, and adding that incremental LCC length to 37{fraction (1/2)} inches, thereby giving a prescribed overall club length for that player.
- 8. The method of claim 7 additionally comprising increasing the prescribed overall club length by one-half inch for increasing ball flight distance.
- 9. The method of claim 7 additionally comprising decreasing the prescribed overall club length by one-half inch for increasing ball flight accuracy.
