Abstract: A method and apparatus for prescribing overall club length for iron-type golf clubs for an individual player wherein the method comprises measuring the erect height (PH) of a player to be fitted, providing the player with a fitting ball club (FBC) having a spherical ball with a hosel bore therein, one end of a golf club shaft in the hosel bore and a golf club grip on the other end of the 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 distance (WFM) vertically from the player's higher wrist to the floor, locating in the first two columns of the FIG. 4 table 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 37½ inches, thereby giving a prescribed overall club length for that player.
