Your swing speed directly affects how far you’ll carry the ball. The graph below plots the carry distances for golfers who have swing speeds of 65, 75, 85, 95 and 105 mph. So if your swing speed is 65 mph, you should never play a hole that requires more than 136 yards of carry off the tee.
Did you know?If you're among the great majority of players, the distance you hit your nine iron equals half the distance you hit your driver. So if you *really* want to know how long someone drives the ball, ask them how far they hit their 9 iron.
