Golf Club Gapping: Why Every Club in Your Bag Needs a Job
Golf Club Gapping: Why Every Club in Your Bag Needs a Job
By Just a Potamus Golf
Here's a question most golfers should be able to answer:
How far does each club in your bag actually carry?
Not how far you hit your 7-iron that one time.
Not the total distance you saw on the simulator after a perfect strike.
Not what the manufacturer's website says.
Your actual, repeatable carry distance.
For a lot of golfers, the answer gets pretty fuzzy.
They might know their driver goes "around 250."
Their 7-iron is their "160 club."
Their pitching wedge is somewhere around 120.
But ask for the actual carry distances throughout all 14 clubs and things start getting interesting.
That's where golf club gapping comes in.
A properly built golf bag isn't just a collection of clubs.
It's a collection of tools.
And every one of those tools should have a job.
What Is Golf Club Gapping?
Golf club gapping is the process of understanding the distance and performance separation between the clubs in your bag.
If your 7-iron carries 160 yards and your 8-iron carries 150, you have roughly a 10-yard carry gap.
Simple enough.
But proper gapping goes beyond subtracting one distance from another.
We also want to understand:
-
Carry distance
-
Total distance
-
Launch
-
Spin
-
Peak height
-
Landing angle
-
Strike consistency
-
How often you can actually produce that distance
Because two clubs can technically travel different distances while still performing almost the same job.
And that's a wasted spot in the bag.
Carry Distance Matters More Than Your Best Shot
This is one of the biggest mistakes golfers make when determining how far they hit their clubs.
They remember the longest one.
You flush a 7-iron 172 yards once.
Now it's your 170-yard club.
But what if your normal solid strike carries 160?
When there's a bunker at 165, that difference suddenly matters.
For most approach shots, we care much more about predictable carry than the longest total distance you've ever produced.
During golf performance and equipment analysis, we're looking for the distance you can reasonably expect from a good, repeatable golf swing.
Not the outlier.
Your bag should be built around reality.
You Don't Need Exactly 10 Yards Between Every Club
Golfers love clean numbers.
"I want exactly 10 yards between everything."
That sounds great.
But golf doesn't always work that neatly.
Your gaps might be:
11 yards.
Then 9.
Then 12.
That's not automatically a problem.
What matters is whether the gaps give you useful coverage for the golf shots you actually face.
A golfer with a 120-yard pitching wedge and a 108-yard gap wedge probably doesn't need to bend something just to make the spreadsheet prettier.
The distances already make sense.
We're looking for functional gaps.
Not mathematically perfect ones.
Loft Gapping and Distance Gapping Are Not the Same Thing
We talked about this in our previous article on loft and lie angles.
You can have perfectly spaced lofts and still have poor distance gaps.
Imagine an iron set with exactly four degrees of loft between every club.
On paper, it looks perfect.
But the golf ball doesn't read the specification sheet.
As clubs get longer and loft decreases, some golfers eventually reach a point where they can't generate enough speed, launch, or spin to maintain useful carry separation.
Maybe the 6-iron carries 155.
The 5-iron carries 160.
The 4-iron carries 162.
You technically have three different clubs.
But do you really have three different tools?
Not necessarily.
The Top of the Bag Is Where Gapping Often Breaks Down
Long irons are a common place for distance compression.
As loft decreases, the golfer needs enough speed and proper delivery to launch the ball effectively.
If that doesn't happen, adding a lower-lofted iron may produce very little additional carry.
That's when we start asking different questions.
Would a hybrid work better?
Would a higher-lofted fairway wood create more usable carry?
Do you even need that club?
Maybe your longest iron is a 6-iron.
There's absolutely nothing wrong with that if the clubs above it cover the distances you need.
The goal isn't carrying a 4-iron because a traditional iron set is supposed to have one.
The goal is building a bag that works.
The Bottom of the Bag Can Have the Opposite Problem
Wedges present a different challenge.
Instead of compressed gaps, we sometimes see enormous ones.
Modern iron lofts have changed significantly.
A golfer may have a pitching wedge that's considerably stronger than the pitching wedge they played years ago.
Then they add the same specialty wedges they've always used.
Now we might have something like:
Pitching wedge: 43°
Gap wedge: 52°
Sand wedge: 56°
That jump from 43 to 52 degrees can create a huge distance hole.
The golfer then spends every round trying to manufacture awkward partial shots in a distance range that could have been covered much more naturally.
This is why wedge gapping should start with the actual pitching wedge in your iron set.
Not with a predetermined belief that everyone needs a 52, 56 and 60.
Your Wedges Need Jobs Too
Distance isn't the only consideration at the bottom of the bag.
Maybe one wedge is primarily a full-swing club.
Another handles most of your pitches.
Another is your bunker and greenside club.
Your lofts, bounce, sole geometry and even custom wedge grinding can be selected around those jobs.
That's why two golfers with identical full-swing distances might still need different wedge configurations.
We're not just filling numbers.
We're filling situations.
Two Clubs Going the Same Distance Isn't Always a Problem
Here's where gapping gets more nuanced.
Suppose your 5-wood and hybrid both carry around 200 yards.
At first glance, one appears redundant.
But what if they produce completely different shots?
The 5-wood launches high and lands softly.
The hybrid flies lower and is easier to use from rough.
Now they may both have legitimate jobs.
Distance is extremely important, but it isn't the only reason a club earns a place in your bag.
Trajectory, spin, landing angle, versatility and consistency matter too.
The real question is:
When would I choose this club instead of the one next to it?
If you don't have a good answer, we may have found a redundant club.
Know the Difference Between Carry and Total Distance
This becomes particularly important at the top of the bag.
Let's say two clubs both finish around 220 yards.
They look identical if we only record total distance.
But one carries 210 and rolls 10.
The other carries 195 and rolls 25.
Those are very different golf shots.
If you need to carry a bunker at 200 yards, only one of those clubs does the job.
That's why a useful bag map shouldn't simply say:
5-Wood: 220
We want to know how the ball gets there.
Your Gaps Can Reveal Equipment Problems
Bag mapping can also expose problems that aren't obvious when hitting clubs individually.
Maybe your 7-iron and 8-iron are almost identical in carry distance.
Why?
It could be your swing.
But it could also be that the actual lofts are too close together.
Maybe one club has moved out of specification.
Maybe the shaft or build of one club is different.
Maybe one head simply isn't producing the launch conditions we need.
That's where performance mapping and physical club measurements can work together.
Instead of immediately replacing something, we find out why the gap exists.
Your Gaps Can Reveal Swing Problems Too
This is the other side of it.
Sometimes we measure the clubs and they're exactly where they should be.
The loft progression makes sense.
The lengths make sense.
Nothing is obviously wrong with the equipment.
But the golfer isn't creating consistent enough contact to produce predictable distance separation.
That's important information.
The answer may not be bending clubs.
It may be improving strike or delivery.
Once again, the question isn't:
"How do we fix this number?"
It's:
"Why is this number happening?"
That's the difference between simply collecting launch monitor data and actually interpreting it.
Your Entire Bag Doesn't Have to Follow the Same Gap
Another common misconception is that if you have 10-yard gaps with your irons, you should have 10-yard gaps everywhere.
That usually isn't necessary.
You might want tighter spacing in your scoring clubs because you're frequently hitting approach shots from those distances.
At the top of the bag, larger gaps may make more sense.
Maybe you have:
Driver: 250 carry
3-Wood: 225
7-Wood: 205
5-Iron: 185
There's nothing inherently wrong with those larger gaps if those clubs cover the shots you actually encounter.
You only get 14 clubs.
Use those 14 spots where they provide the most value.
Don't Build Your Bag Around Club Numbers
One of the simplest ways to think differently about your bag is to stop caring so much about the number stamped on the sole.
You don't need a 4-iron.
You don't need a 3-wood.
You don't need exactly four wedges.
You need clubs that cover the golf shots you face.
If a 7-wood does the job better than a 4-iron, use the 7-wood.
If a 5-wood works better than a 3-wood, use the 5-wood.
If three wedges cover everything you need, you may not need four.
The club number doesn't go on the scorecard.
Sometimes Your Current Bag Just Needs a Few Adjustments
Just like we discussed with loft and lie, poor gapping doesn't automatically mean you need new equipment.
Maybe your current set is already very close.
We might be able to:
-
Adjust a loft
-
Correct a club that's out of specification
-
Change the spacing of your wedges
-
Identify one redundant club
-
Fill one obvious distance hole
You don't necessarily need new shafts, new heads, new grips or an entirely new set.
Sometimes a few intelligent changes can make the equipment you already own much easier to use.
That's one reason we measure before recommending.
Blueprinting and Bag Mapping Answer Different Questions
This is where it's useful to separate two types of information.
A club blueprint tells us about the physical equipment.
We can document specifications such as loft, lie, length and other relevant club measurements.
That tells us:
What is actually in your bag?
Bag mapping tells us what happens when you hit those clubs.
We measure the performance and distances throughout the set.
That tells us:
What does your bag actually do?
Those are different questions.
And when we combine them, we get a much more complete picture.
Complete Bag Performance Connects the Equipment to the Results
This is why we offer three different levels of bag evaluation at Just a Potamus Golf.
Our Blueprint Specs Map measures and documents the physical specifications of your current clubs.
Our Bag Mapping focuses on the actual performance and distances of each club.
And our Complete Bag Performance combines both.
That allows us to compare what's physically built into the equipment with what the golf ball is actually doing.
If there's a strange distance gap, we can look for a reason.
If two clubs overlap, we can determine whether they're truly redundant or simply produce different useful trajectories.
If one club behaves differently from everything around it, we can investigate why.
The objective isn't creating a prettier spreadsheet.
It's creating a more useful golf bag.
The Best Bag Isn't Necessarily the Most Expensive Bag
You can have fourteen perfectly new clubs and still have a poorly constructed golf bag.
You can also have clubs from several different generations and manufacturers that work together extremely well.
Matching logos don't create good gapping.
Performance does.
That's why I don't care whether every club in your bag came from the same manufacturer.
I care whether each one does what we need it to do.
Every Club Should Answer One Question
Look at any club in your bag and ask:
Why is this club here?
Your driver has an obvious answer.
Your putter does too.
But what about everything between them?
Why do you have that 4-hybrid?
What does your 5-wood do that your 3-wood doesn't?
What distance is your gap wedge actually responsible for?
When do you choose your 58 instead of your 54?
If you can clearly answer those questions, you're probably building a useful bag.
If you can't, there's an opportunity to improve it.
Stop Guessing Your Distances
Knowing your distances doesn't make golf easy.
You still have to hit the shot.
But standing over a 147-yard approach without knowing whether your 8-iron carries 142 or 152 makes an already difficult game unnecessarily harder.
Good decisions require good information.
That's the purpose of bag mapping.
We're not trying to make every club go farther.
We're trying to make every club more predictable.
That's how we approach golf instruction, club fitting, bag mapping and precision club building at Just a Potamus Golf.
If you're in Valparaiso, Chesterton, Portage, Michigan City, Crown Point, LaPorte, Merrillville or anywhere throughout Northwest Indiana and you've never actually mapped your entire bag, you may be surprised by what you find.
Maybe everything is exactly where it should be.
Maybe two clubs are doing the same job.
Maybe you're missing an important distance.
Maybe one simple loft adjustment fixes the entire problem.
The point is knowing.
Measure the bag. Understand the gaps. Give every club a job.
