A method for selecting a golf ball suitable for a golfer, comprising the steps of (i) obtaining head speed and backspin when a golfer hits a golf ball with a golf club; (ii) obtaining from the golfer ball-type selection data for determining which among a plurality of ball types is suitable for the golfer; and (iii) selecting a golf ball of a type (e.g., a distance-type ball or a control-type ball) suitable for the golfer on the basis of the head speed and backspin obtained in step (i) and the ball-type selection data obtained in step (ii), in such a manner that the selected golf ball produces backspin close to optimal backspin corresponding to the above-described head speed.
