What Really Happens During a Professional Putter Fitting?

By Joel Pera | Just a Potamus Golf

Putting is one of the strangest parts of golf when it comes to equipment.

Golfers will spend hours getting fit for a driver.

They'll compare iron shafts, launch angles, spin rates, and carry distances.

Then they'll walk into a golf shop, roll six putters across a piece of artificial turf, pick the one that makes a few putts, and call it good.

Or even more commonly:

They buy the putter they like looking at.

There's nothing wrong with liking your putter. In fact, confidence and appearance absolutely matter.

But a putter is still a golf club.

Its length, loft, lie, head design, balance, weight, and grip all interact with the person using it.

And unlike a driver that you may hit 10 or 12 times during a round, your putter could easily be used 30 times or more.

So why wouldn't we fit it?

At Just a Potamus Golf, a professional putter fitting isn't about finding the putter that happens to make the most putts during a short session.

It's about understanding your stroke, your setup, how the putter interacts with both, and what gives you the best opportunity to start the ball where you intend with predictable speed.

A Putter Fitting Starts With the Golfer, Not the Putter Rack

Before changing anything, we need to understand what you currently do.

How do you set up?

Where are your eyes?

How do your hands interact with the grip?

How much do you naturally rotate the face?

What's happening at impact?

What does your current putter encourage you to do?

And just as importantly:

What are you trying to fix?

Maybe you consistently miss left.

Maybe you push short putts.

Maybe your speed control is inconsistent.

Maybe you don't aim where you think you're aiming.

Or maybe you don't have an obvious problem at all. You simply want to know whether the putter in your hands actually fits you.

The first step isn't grabbing another putter.

It's establishing a baseline.

This Is Where CAPTO Gen 3 Comes In

At Just a Potamus Golf, we use CAPTO Gen 3 for putter analysis and fitting.

Instead of relying only on what a stroke looks like to the eye or whether a few putts happen to fall, CAPTO allows us to measure what's actually happening throughout the stroke.

That gives us objective information we can combine with what we're seeing from the golfer.

We're not looking for one magic number.

We're building a picture of how you deliver the putter.

The technology gives us information.

The fitting is understanding what that information means for you.

Face Control Matters

One of the most important parts of putting is controlling the face.

You can make a stroke that looks beautiful and still struggle if the face isn't consistently delivered where you need it.

During a putter fitting, we want to understand what the face is doing throughout the stroke and, most importantly, through impact.

Is there a consistent pattern?

Are you delivering the face predictably?

Are you constantly fighting the putter to get it back where you want it?

This is where putter design and the golfer's natural movement begin to interact.

The goal isn't necessarily to create a perfectly square-looking stroke.

The goal is to help you deliver the putter consistently.

---

Your Stroke Doesn't Need to Look Like Everyone Else's

Putting instruction has gone through plenty of trends.

Straight back and straight through.

Arc the putter.

Lock the wrists.

Let the putter release.

The problem comes when we decide every golfer should move the putter exactly the same way.

People are built differently.

They set up differently.

They perceive lines differently.

They move differently.

A good putter fitting shouldn't force every golfer toward one predetermined stroke.

Instead, we want to understand your natural tendencies and determine whether the putter supports them or makes them harder to control.

Just like the rest of the golf bag:

We're fitting the golfer, not an idealized model.

---

Putter Length Is More Important Than Most Golfers Realize

Putter length doesn't simply determine whether the club reaches the ground.

It influences your entire setup.

Change the length and you can change:

• Posture

• Eye position

• Distance from the ball

• Arm hang

• Hand position

• How the putter moves

A putter that's too long may force you into a setup that doesn't feel natural.

A putter that's too short can do the same thing in the opposite direction.

This is why choosing length based only on your height isn't enough.

Two golfers who are both 5'10" may set up completely differently and need different putter lengths.

We care about how the putter fits your actual posture and stroke.

---

Lie Angle Matters in a Putter Too

Lie angle isn't only an iron-fitting specification.

If the putter's lie doesn't match your setup, the toe or heel may sit excessively off the ground.

Because a putter still has loft, lie angle can influence where the face is effectively oriented.

But just like we discussed with irons in our article on loft and lie, we don't want to adjust equipment simply because of what it looks like while you're standing still.

We want to see what happens when you actually putt.

Your setup and your equipment need to work together.

---

Putter Loft Isn't Just a Number on a Specification Sheet

Yes, putters have loft.

And that loft has a job.

The golf ball sits down slightly into the putting surface. We need to launch it properly so it can transition into a predictable roll.

But once again, static loft isn't the whole story.

The loft built into the putter and the loft you actually deliver can be different.

Your hand position, shaft orientation, setup, and stroke all influence the delivered loft at impact.

One golfer might add loft.

Another might significantly reduce it.

Giving both golfers the exact same putter because the manufacturer's stated loft is "standard" ignores how they're actually delivering it.

Head Design Is More Than Looks

Blade.

Mallet.

Wide-body blade.

High-MOI designs.

Different neck configurations.

Different balance concepts.

There are more putter designs available now than ever before.

And yes, appearance matters.

You need to be comfortable looking down at your putter.

But head design can also influence:

• Alignment

• Stability

• Face behavior

• Weight distribution

• How the putter feels throughout the stroke

A golfer may naturally aim one style better than another.

Another may gain more consistency from a different balance or head shape.

The answer isn't:

"Mallets are more forgiving, so everyone should use a mallet."

The answer is:

Which design actually helps this golfer perform?

---

What About Toe Hang, Face Balance, and Zero Torque?

This is where putter fitting has become particularly interesting.

For years, golfers were commonly told that a strong arc needed more toe hang and a straighter stroke needed a face-balanced putter.

That's a useful starting concept, but putting is more complicated than matching one stroke description to one balance category.

Today we also have traditional face-balanced designs, varying amounts of toe hang, different shaft-axis locations, and zero-torque concepts designed to influence how the face behaves during the stroke.

None of those designs is automatically right for everyone.

And none is automatically wrong.

The important question is what happens when you use it.

Does it improve face control?

Does it help your start line?

Does it work with your natural motion?

Do you feel like you're swinging the putter or fighting it?

That's why we test rather than choosing a putter based on a category.

---

Grip Size and Shape Can Change More Than Comfort

The putter grip is your connection to the club.

Changing its size or shape can change how your hands interact with the putter.

A larger grip may quiet certain hand action for one golfer.

Another golfer may lose feel with that same grip.

Different shapes can also influence how naturally your hands sit on the club and how you perceive the orientation of the putter face.

There isn't one perfect putter grip.

The correct grip is the one that helps you create a comfortable, repeatable setup and stroke.

Making Putts During a Fitting Can Be Misleading

This may sound strange, but whether every putt goes in isn't necessarily the most important part of a putter fitting.

Obviously, we want to make putts.

That's the entire point of putting.

But during a short indoor fitting, a ball can go into the hole for the wrong reasons.

You can pull a putt that you aimed right.

You can push one that you aimed left.

You can make one with poor speed because the hole happened to get in the way.

If we judge equipment solely by makes and misses, we can easily misunderstand what happened.

That's why measured data matters.

We're trying to identify something repeatable, not crown a winner because you happened to make three putts in a row with it.

---

Sometimes Your Current Putter Is Already the Right Putter

This is one of my favorite outcomes from any fitting.

You don't always need something new.

Maybe you already own a putter you love.

Maybe the head design works well with your stroke.

Maybe your face control is good.

Maybe the problem is simply that it's a little too long.

Or the lie needs adjustment.

Or the loft needs to change.

Or a different grip would put your hands in a better position.

A professional putter fitting doesn't have to end with buying a putter.

Sometimes it ends with making the putter you already own work better.

And sometimes we measure everything and determine that your current putter fits you extremely well.

That's valuable information too.

Now we can stop blaming the equipment and focus somewhere else.

---

Sometimes the Problem Isn't the Putter at All

This is where being both a fitter and an instructor becomes important.

What if the data tells us the putter is doing exactly what it should?

What if the equipment fits, but your setup changes from putt to putt?

What if your face control problem is coming from the stroke?

What if your speed control needs work?

Buying another putter doesn't solve those problems.

That's the same philosophy we've used throughout this entire series.

Don't automatically blame the golfer.

Don't automatically blame the equipment.

Figure out what's actually happening first.

Then decide what deserves to change.

A Putter Fitting Should Give You Answers

At the end of a professional putter fitting, I want you to understand more than which putter produced the best numbers.

You should understand:

• How you naturally set up

• How you move the putter

• How you control the face

• What your current putter is doing

• Which specifications matter most for you

• Whether your existing putter can be adjusted

• What characteristics to look for if a different putter makes sense

That's much more useful than:

"This one made the most putts."

Because now we're making an informed equipment decision.

The Putter Is Part of the Same System

This entire blog series has focused on one idea:

Your swing and your equipment don't exist independently.

That applies just as much on the putting green as it does with a driver or 7-iron.

Your setup influences the putter.

The putter influences your setup.

Your stroke influences how the club is delivered.

The club's specifications can influence how easily you repeat that stroke.

That's why our golf performance services look at the golfer and the equipment together.

At Just a Potamus Golf, our putter fitting uses CAPTO Gen 3 analysis alongside the same philosophy we use throughout our fitting and instruction:

Measure. Diagnose. Then decide what actually needs to change.

If you're in Valparaiso, Chesterton, Portage, Michigan City, Crown Point, LaPorte, Merrillville, or anywhere throughout Northwest Indiana and you've never had your putter professionally evaluated, it may be worth finding out whether the club you use more than anything else in your bag actually fits you.

You might need a different putter.

You might need an adjustment.

You might need to work on your stroke.

Or you might discover the putter already in your bag is exactly where it belongs.

The point of the fitting is finding out.
