By Rowena Pedrena. A traditional golf set has 13 clubs: three woods, nine irons (including three wedges) and one putter. The USGA limits the number of clubs a player may carry in his or her bag to 14. A player may include an additional wedge or wood to a fill a gap in hitting distance.
Updated July 11, 2016. Fourteen clubs are the maximum allowed in one player's golf bag during a round played under the Rules of Golf. Any number below 14 is fine, but more than 14 is not. Also, those 14 clubs cannot be changed during the course of one round. You must finish with the 14 you started with.
