Knowing the measurements of golf drivers allows you to choose a club that is the correct fit for your body. You will first have to measure yourself to determine the size you need. You can then measure the golf shafts to choose the one most suited to your height and arm length. Measuring golf clubs also allows you to verify that the clubs conform to United States Golfing Association's (USGA) maximum club length of 48 inches.
Measure the distance between your wrist and the ground, while you are standing straight up. The wrist would be measured where it joins the hand. You may need a friend to measure the distance for you. This measurement is the optimal length of a golf club.
Measure the distance from the end of the handle grip to where the head of the club first angles out. This will be the lower, back end of the striking area. This measurement is the USGA method of measurement.
Stand the golf club straight up against a wall. Measure the distance from the ground to the top end of the handle grip. This is the Long Drivers of America method for measurement.
