A golf club set comprises at least three golf clubs having different loft angles changing progressively from the smallest loft angle of the lowest numbered golf club to the largest loft angle of the highest numbered golf club. Each of the golf clubs comprises a shaft and a head, the head provided with a hosel having a shaft inserting hole into which the shaft is inserted. In a standard state of each golf club in which the head is disposed on a horizontal plane so as to show its lie angle and loft angle, the clubs satisfys the following conditions<paragraph lvl="0"><in-line-formula>Ln<=L(n+1)</in-line-formula><paragraph lvl="0"><in-line-formula>L(n=1)<L(n=m)</in-line-formula><paragraph lvl="0"><in-line-formula>dn>=d(n+1)</in-line-formula><paragraph lvl="0"><in-line-formula>d(n=1)>d(n=m)</in-line-formula>wherein L is a hosel length, d is an inside diameter of a shaft inserting hole, suffix "n" to "L" and "d" means the order number of the club in the ascending order from the lowest numbered club (n=1) to the highest numbered club (n=m), and m is the number of the golf clubs, and the hosel length of each club is defined as a length measured from the upper end of the hosel to the horizontal plane along the central axis of the shaft.
