Gapping explained
When we speak about gapping we are referring to the distance between each club in your bag. Bad gapping, as showcased with the red arrows above, leaves you with uneven or large distances between clubs, often of over 20 or 30 yards. In contrast, good gapping would see you have equal gaps between clubs that are no bigger than 15 yards.

Benefits of good gapping
The most obvious benefit of good gapping is not hitting two clubs similar distances, as illustrated by the hybrid and 5-wood above. If you find yourself between clubs on a shot, having equal gaps will also mean you are much closer with your next club, so you won’t have to manufacture shorter/longer swings or hit soft/hard shots.
