Golf ScoutClub gapping calculator
Enter how far you hit each club to see the gap to the next one, and spot clubs that go the same distance or gaps with no club to fill them.
What good gapping looks like
Most club golfers carry 13 or 14 clubs, and the useful thing is a steady step between them, often 10 to 15 yards through the irons and wedges. A gap much smaller than that means two clubs doing one job; a much bigger one leaves shots you have no full swing for. The flags above are rules of thumb you can change.
Use the distances you hit on the course, not your best on the range, and the same measure for every club: total distance, or carry if that's what you know.
Golf Scout's Bag keeps how far you hit each club, and learns from the shots you mark. Get it on the App Store.
