Finding golf clubs that are the correct size is not usually a difficult assignment. Male golfers who are between 5 feet 7 inches and 6 feet 4 inches can generally find clubs off the shelves that fit. Female golfers between 5 feet 2 inches and 5 feet 11 inches can also find clubs that are the right size. However, golfers have to determine what type of shafts they want (stiff or regular), what type of swing they have and what their handicap is before they make a purchase.
Have a golf pro or salesperson look at your swing before you buy clubs. You may have been playing with stiff-shafted clubs, but as the years have gone by, you may not generate as much clubhead speed as did when you were younger. Therefore, you may need graphite shafts so you can get the distance you once did.
Purchase longer clubs if you want to create a longer swing plane. Perhaps you don't like the whippy graphite shafts and you want to stick with stiff shafts. Longer clubs will help you create more distance, because you will have a longer, flatter swing plane. This is a difficult swing to master, but many senior golfers choose to go this route.
Hold the club as you would if you were getting ready to hit the ball. Bend your knees a few degrees and bend slightly at the waist. When you place the club in a hitting position, it should be in a straight line with the ball. If you have to move your arms and create an angle to get the clubhead behind the ball squarely, then you need a different club size.
Have measurements taken if standard-sized clubs feel uncomfortable. If you have longer arms than average, you may need shorter clubs. If you have shorter clubs than average, you may need longer clubs.
Try out the clubs before you spend any money on them. Most reputable pro shops or golf shops will let you hit with clubs you are considering for purchase inside a golf simulator or even let you take them to the range. They have to feel comfortable before you buy them.
