Can You Add an Inch to a Golf Club?

Thinking about adding an inch to your golf clubs? You absolutely can, and for many golfers, it's a small change that can lead to big improvements in comfort and ball striking. This isn't some back-shop secret reserved for the pros, it's a common and straightforward modification. This guide will walk you through exactly why you'd consider it, the pros and cons you need to weigh, and how you can do it yourself or find the right professional to help you out.

Why Would You Add an Inch to Your Golf Clubs?

The most common reason for lengthening a golf club is also the most obvious: you’re taller than the average person. Standard, off-the-rack golf clubs are typically built for a male golfer around 5’9” to 5’10”. If you're pushing 6'2" or taller, hunching over a standard-length iron can feel unnatural and force you into a poor setup posture. Adding length allows you to stand taller and more athletically, putting you in a much better position to make a powerful, repeatable swing.

But it's not just about height. It's about your body's specific proportions. The key static measurement for club fitting is the "wrist-to-floor" distance. Here’s how you can get a rough idea:

• Stand on a hard surface with your golf shoes on, keeping your posture upright but relaxed.
• Let your arms hang naturally at your sides.
• Have a friend measure the distance from the floor to the crease of your wrist (the one closer to your hand).

If that measurement is particularly long, you’re a prime candidate for longer clubs, regardless of your overall height. Lengthening your clubs can help normalize your setup, preventing you from reaching for the ball and promoting a more naturally rotational swing powered by your body, not just your arms.

The Pros and Cons of Lengthening Your Clubs

Before you run to the workshop, it's helpful to understand that changing club length isn’t a simple one-for-one swap. It affects other aspects of the club's performance. Here's what you need to know.

The Potential Benefits

• Better Posture and Comfort: This is the biggest win. Standing more upright reduces strain on your lower back and allows for a freer, more athletic turn away from the ball and through impact. You’ll feel more balanced and powerful in your stance.
• Increased Clubhead Speed: A longer lever creates a wider swing arc. A wider arc, all things being equal, can generate more clubhead speed. This can translate to more distance, especially with your driver and longer irons.
• More Consistent Center-Face Contact: For a taller player who is constantly hitting the ball thin or toward the toe, a longer shaft can be the simple fix that helps them find the sweet spot more consistently without having to drastically alter their swing. It brings the clubhead into their natural impact zone.

The Potential Drawbacks to Watch For

This is where things get a bit more technical, but it's important stuff. Simply adding an inch without considering these factors can create new problems.

• It Changes the Swing Weight: Swing weight is a measurement of how heavy the clubhead feels during the swing. It’s measured on a scale like C8, D2, D5, etc. Adding length makes the clubhead feel heavier. Just adding a half-inch can increase the swing weight by about 3 points (e.g., from D2 to D5). This can make the club feel sluggish or unwieldy, throwing off your timing and tempo.
• It Softens the Shaft Flex: Adding length to a shaft makes it play softer. An extension adds leverage, causing the shaft to bend more during the swing. Your "stiff" flex shaft might start to perform more like a "regular" flex. This can lead to a higher, less controlled ball flight and a feeling of instability at impact, especially for players with faster swing speeds.
• It Alters the Lie Angle: As you make a club longer, the lie angle becomes more upright at impact. Lie angle is the angle between the shaft and the ground when the club is soled correctly. A more upright lie angle will cause the toe of the club to be off the ground at impact, forcing the heel to dig in. For a right-handed golfer, this will cause the ball to pull to the left. This is usually the most significant and often-overlooked consequence of lengthening clubs.

The DIY Guide: How to Add an Inch to a Golf Club

Feeling handy? Lengthening a club is a very doable project. Just take your time and be precise. While this is a great skill to learn, remember that if you're not fully comfortable, a golf shop or a club builder can do this for a very reasonable price. This guide assumes you’re extending a steel-shafted iron, which is the most common scenario.

What You'll Need

• Shaft Extension: Make sure you get the right kind. They come in steel or graphite, and in different diameters to fit your specific shaft.
• Strong Epoxy: Don't use 5-minute hardware store epoxy. Get a high-strength, 24-hour cure epoxy. Golf-specific epoxies are formulated to handle the intense vibrations of impact.
• Tools for Grip Removal: A hook blade is fastest, but requires caution. A grip removal tool is safer.
• Heat Source: A heat gun is ideal. A propane torch can work, but you have to be extremely careful not to overheat and damage a graphite shaft.
• Vise and Rubber Shaft Clamp: You need this to hold the club securely without crushing the shaft when removing and installing the grip.
• New Grip, Grip Tape, and Grip Solvent: Since you'll be removing the old grip, you'll need a full set to finish the job.

Step 1: Remove the Old Grip

Secure the club in your vise using the rubber clamp. Using your hook blade, cut away from your body, slicing through the grip and the tape underneath. Peel it all off and discard it.

Step 2: Prepare the Shaft and Extension

Your goal is to create a strong bond for the epoxy. Scrape out any old grip tape residue from the inside of the shaft butt. Take some sandpaper or a small file and lightly scuff up the surface of the shaft extension plug and the inside of the club shaft. This roughs up the surfaces and helps the epoxy grab on tight. Wipe both surfaces with a bit of alcohol to make sure they are clean, dry, and free of dust.

Step 3: Mix and Apply Epoxy

Following the manufacturer's instructions, mix a small amount of your 24-hour epoxy. Apply a thin but complete coat to the part of the extension plug that will be inserted into the shaft. Then, apply a small amount just inside the opening of the shaft itself. A twisting motion as you apply helps ensure full coverage.

Step 4: Install the Extension and Clean Up

Push the extension firmly into the shaft with a slight twisting motion until it is fully seated. Some epoxy will likely squeeze out. Wipe this excess away immediately with a rag before it starts to set. Double-check that the extension is straight and flush.

Step 5: Let It Cure Correctly

This is where patience pays off. Stand the club upright (extension-side up) somewhere safe where it won't be disturbed. Let the epoxy cure for its full recommended time - usually 18-24 hours. Don’t get antsy and try to re-grip it early, as you could break the bond.

Step 6: Install the New Grip

Once the epoxy is fully cured, you can cut the shaft to its final desired length if the extension was too long. Then, it's just a standard re-gripping process. Apply your new grip tape, lubricate it with solvent, and smoothly slide on the new grip, making sure to align the logo or pattern correctly before the solvent evaporates.

The Pro Route: Working With a Club Fitter

While the DIY route is empowering, working with a professional club fitter or builder eliminates all the guesswork. They don't just add length, they fine-tune the club to your swing.

Here’s why it's often the better choice:

• Precise Lie Angle Adjustment: After lengthening, they will put your club on a lie angle machine and physically bend it to the correct angle for your swing, ensuring your shots fly straight.
• Swing Weight Management: They can add weight back to the grip end (counter-balancing) or use lighter clubheads to return the swing weight to a level that feels good to you.
• Dynamic Fitting: Instead of just a static wrist-to-floor measurement, they'll watch you hit balls with impact tape on the face and a launch monitor. They can see exactly how the length is affecting your strike location, launch, and spin, and make adjustments based on real data, not just theory.

A fitter turns a simple modification into a full optimization, confirming that the change is legitimately helping your game.

Final Thoughts

Adding an inch to a golf club is a perfectly valid way to customize equipment for a better fit, especially for taller players or those with unique body types. You need to be mindful of how that extension will impact the club's swing weight, flex, and lie angle, but a proper adjustment can lead to a more comfortable posture and a more powerful, consistent golf swing.
