There are a number of factors that go into determining the type and size of golf clubs you will need. Standard golf clubs that have 42-inch shafts will fit 80 percent of the golfers that walk into a sporting goods store. However, size is just one of the factors you should consider when purchasing clubs. A golfer's age, handicap and sex have to be considered as well.
Go to a golf specialty store and get a professional recommendation on the size and type of clubs you need. You will be asked to swing a club in a golf simulator, and your swing may be videotaped. You also need to tell the salesperson whether you are a long hitter, an accurate hitter and what your average score has been over the past three months.
Be measured by a golf professional. The key measurement will be your arm length compared to your height. If your arms are longer than average, you will need shorter clubs to have your best chance to score well on the golf course. If your arms are shorter, you will need longer clubs to have your best chance to generate power.
Buy stiff-shafted clubs if you are a long hitter, but struggle with accuracy. Stiff shafts tend to flex and bend less during the course of the swing, and they rely on the golfer to supply the power. However, by bending less, you are more likely to make square contact with the ball, and this should help you keep the ball in the fairway.
Purchase regular-shafted clubs if you have a tendency to keep the ball in the fairway, but you would like more accuracy. Regular shafts have more flexibility and will flex more during the course of the swing. That will create greater clubhead speed on impact, which will give you more distance.
Consider longer clubs than you have used previously if you are in your late 50s or older. As the years go by, you won't be able to generate the power you once did. Longer clubs will give you a bigger swing plane, and that will help you regain the distance you have lost.
Tips & Warnings
Make sure you get a chance to swing any clubs that you are preparing to purchase. Many golf pro shops and golf specialty stores will let you hit inside a golf simulator, and some may even let you take the clubs to the driving range, so you can make a full determination of whether you like them or not.
