There are two basic things that must be considered when a golfer is measured for new clubs. First, his strength and abilities must be assessed; then his measurements have to be taken. Together, they are all a club fitter needs to know to make sure that your new clubs not only fit you, but will go a long way toward lowering your golf score. Buy your clubs "off the rack" and you stand a good chance that they will not fit you because they are made for the "average" player.
Difficulty: Moderately Easy
Write down your height and the distance between the tips of your fingers and the floor to determine what length your clubs should be. Just because you are tall doesn't mean that you need longer clubs, because you may also have long arms. Someone who is short but has short arms, on the other hand, may need longer clubs. Many male golfers think it is macho to have clubs with longer shafts. Actually, those clubs do hit the ball a bit longer, but you will be sacrificing accuracy. Once again, it's wise to factor in the importance of distance versus accuracy when choosing the lengths of your shafts.
Decide between steel and graphite shafts. Steel-shafted clubs are generally less expensive, but graphite shafts are lighter. And because graphite shafts are lighter, they are up to 1 inch longer than steel shafts, depending on the club.
Figure out which club you would use to hit the ball 150 yards; then factor in a self-assessment of your game to determine how much flex you need from your shafts. The club you use will give the club fitter an idea about your clubhead speed and thus the flex of the shafts that you should have. For instance, if you use a long iron, a hybrid club or a wood to hit the ball 150 yards, you most likely will need a shaft with a lot of flex. But if you can hit an 8 or 9 iron 150 yards, you probably need a shaft that is stiffer.
Make sure that the clubs lie flat when you address the ball. An easy way to tell the lie of the clubs is to swing once on a board that is placed on the ground. You will be able to tell quickly if the toe or heel of the club is resting on the ground. If the toe is touching the ground and you are right-handed, most likely you will hit a lot of shots to the right for that reason. And you have a tendency to hit the ball to the left if the heel is touching the ground. A minor adjustment of your irons is all that is necessary to have the clubs lie flat.
