What gapping actually means

Gapping is the spacing of carry distances between the clubs you own. In an ideal set the gaps are even, so every yardage inside your range has one club that covers it comfortably. That is the whole idea. It is not glamorous and no manufacturer builds a campaign around it.

The trouble is that a set is rarely bought as a set. An iron head from one generation, a hybrid picked up because it looked good, two wedges chosen years apart, a gap wedge that was thrown in. Each decision was sensible on its own. Together they produce a ladder with a rung missing and two rungs welded on top of each other.

Club-fitting practice is consistent on this point: uneven loft gaps through a set produce overlapping carry distances at one end and uncovered yardages at the other. Both at once, usually.

Why the overlap hides so well

An overlap is silent. If your five and your four hybrid go the same distance, nothing bad happens. You hit one of them, the ball goes a sensible distance, and you never learn that the other was redundant. No shot is ever lost to an overlap directly.

What you lose is the club that could have been there instead. A bag holds fourteen. If two of them do the same job, you are playing with thirteen and a spare. Somewhere in your range there is a yardage with nothing on it, and that is where the cost shows up — in the shot you have to force, or ease off, or hood, or hit thin because you are trying to make a club be something it is not.

The gap announces itself. The overlap pays for it quietly.

The wedges are usually the worst of it

Most amateur bags are tidy through the long irons and chaotic at the bottom. A pitching wedge from a modern set can be considerably stronger in loft than the number suggests, and if the sand wedge was bought separately, the space between them can be enormous.

We have written elsewhere in this series about loft creep and why a seven-iron is not what it was twenty years ago. The same drift is what opens the wedge gap. The pitching wedge got stronger. The sand wedge did not. Nobody told the golfer.

The practical result is a thirty-yard hole in the part of the course where you play the most shots and where distance control matters most. That is an expensive place to be guessing.

How to find your own gaps

You do not need a fitting to start. You need carry numbers, and you need them to be carry rather than total, because roll varies with everything and carry does not.

Take a launch monitor session or a session on a range with reliable distance markers, and hit five to eight shots with each club from the pitching wedge upwards. Ignore the best one. Ignore the worst one. Write down the middle. That number is your club, not the one you hit at your very best on a warm evening.

Then write the numbers in a column and read the differences. You are looking for two things only: a pair that are within a few yards of each other, and a stretch where the difference is much larger than the rest. You will probably find both, and you will probably already have suspected where.

The marginal gain

Fixing gapping is not a swing change. Nothing about how you move needs to alter. You are simply making the fourteen clubs you are allowed to carry do fourteen different jobs instead of thirteen.

It is also one of the few improvements that works on a bad day. On a good day you can manufacture a shot with the wrong club. On a bad day you cannot, and that is exactly when the missing yardage arrives.

The whole thing costs an hour with a notebook. Not every marginal gain is that cheap.
