Abstract
A golf club set includes a plurality of golf clubs having different loft angles. The plurality of golf clubs have the same lie angle. Each loft angle difference between two golf clubs that are adjacent in a loft angle order is the same. Each club length difference between two golf clubs that are adjacent in the loft angle order is 0.125 inches (3.175 mm) (inclusive) to 0.375 inches (9.525 mm) (inclusive). A loft angle of a golf club having a minimum frequency is smaller than a loft angle of a golf club having a maximum frequency. A difference between the minimum frequency and the maximum frequency is not less than 40 cpm.
