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.
Most golfers decide to go with something in the middle. In addition, you can buy sets of golf clubs. Basic golf clubs cost between $200 and $400 for a complete set with the golf bag included, on up to a price between $800 and $2,500, or even more for a set of premium golf clubs.
