What Golfer Uses the Same Length Clubs?

The name you're most likely looking for is Bryson DeChambeau, the PGA Tour pro famously known as The Scientist. But he's not the only one, and the concept of using single-length, or one-length, irons goes beyond just one player. This article will break down exactly what single-length clubs are, who uses them, the significant advantages and potential drawbacks, and ultimately, help you decide if they might be a good fit for your own game.

The Player Who Popularized Single-Length Irons: Bryson DeChambeau

While a few smaller brands and golfers dabbled with the concept for decades, Bryson DeChambeau smashed the idea into the mainstream. His analytical and physics-based approach to golf is a perfect match for the single-length iron philosophy. DeChambeau believes that if he can reduce the number of variables in his golf swing, he can increase his consistency. By making every iron shaft the same length, he eliminates the need to change his posture, stance, and ball position from club to club.

He worked with his coach, Mike Schy, to develop a set where every iron - from his 4-iron down through his wedges - was built to the length of a standard 7-iron (around 37.5 inches). This allows him to make the exact same machine-like swing motion with his 5-iron as he does with his 9-iron. For Bryson, it's about making golf a more repeatable science, and single-length irons are a fundamental part of his experiment.

What Exactly Does "Same Length Clubs" Mean?

When we talk about single-length or one-length irons, we are referring to an iron set where every club has the same shaft length. In a traditional golf set, the clubs get progressively shorter as the loft increases. Your 4-iron is the longest, your 5-iron is a half-inch shorter, your 6-iron is another half-inch shorter, and so on, all the way down to your wedges.

A single-length setthrows that idea out the window. Here’s the setup:

• Consistent Length: Every iron, typically from the 4 or 5-iron through the pitching and gap wedge, has the exact same shaft length. This length is usually that of a standard 7 or 8-iron.
• Consistent Lie &, Weight: To make the system work, the lie angle (the angle between the shaft and the sole of the club) and the head weight of each iron are also consistent across the set.
• Varied Lofts: The only thing that changes significantly from club to club is the loft on the clubface. A 4-iron will have a very strong loft to make the ball go far, while a pitching wedge will have a high loft to make the ball go shorter and higher. This is how distance gapping between clubs is achieved.

The entire principle is built on creating one setup and one swing, allowing you to focus on execution rather than constantly adapting to different club lengths.

The On-Course Pros of Using Single-Length Irons

From a coaching perspective, the theory behind one-length irons is very appealing, especially for certain types of golfers. The benefits are all centered on one idea: simplicity.

1. Repeatability and Consistency

This is the number one reason to even consider single-length irons. With a traditional set, you have to subconsciously adjust your address position for every single iron. Your posture is slightly more bent over with a 9-iron than it is with a 5-iron. The ball position moves slightly forward in your stance as the clubs get longer. With one-length irons, these variables vanish. You learn one setup - one posture, one stance width, one ball position - and you apply it to every iron shot. This can make your swing incredibly repeatable, particularly under pressure.

2. More Effective Practice

When you go to the driving range with a single-length set, every swing you make with a 9-iron is actively reinforcing the same physical movements you need for your 6-iron. You're grooving one swing path, one address position, and one feel. It makes practice time highly efficient. You're not just practicing hitting a specific club, you are practicing your singular "iron swing."

3. Easier to Hit Long Irons

Let's be honest: for most amateur golfers, the traditional 4- and 5-irons are intimidating. Their long shafts can feel unwieldy and difficult to control. A single-length 4-iron, being built on a much shorter 7-iron shaft, feels far more manageable. Many players find they make more consistent, centered contact with the shorter shaft, which often leads to better and more reliable distance than they got with their old, traditional long irons.

The Potential Cons and Challenges of Switching

If single-length irons were definitively better for everyone, we'd all be using them. But there are very real challenges and trade-offs that stop this from being a one-size-fits-all solution.

1. The Jarring Adjustment Period

If you've played with traditional clubs for any length of time, switching to one-length feels weird. Really weird. Your pitching wedge will feel unusually long in your hands, and your 4-iron will feel shockingly short. Looking down at a wedge that appears as long as your mid-irons can be visually unsettling and requires a genuine commitment to overcome. You have to reprogram years of muscle memory and visual cues.

2. Gapping and Trajectory Issues

This is the biggest technical hurdle. While manufacturers have gotten much better at engineering these sets, some players still struggle to get consistent distance gaps between their clubs. For some, the long irons may not fly as high or as far as they’d like, and for others, the short irons might fly too far or on a lower-than-ideal trajectory. Dialing in your distances and making sure there isn't too much "bunching" in the short or long end of your bag is essential.

3. The Wedge Game Dilemma

For many golfers, myself included, the scoring game is about feel and versatility. A traditional-length wedge is a precision tool used for delicate chips, pitches, and bunker shots. Making those same nuanced shots with a longer 7-iron shaft can feel clumsy and restrictive. Many accomplished players feel they lose the touch and control needed around the greens with an extended shaft, which is why even some single-length proponents will carry traditional-length wedges.

A Coach's Advice: Should You Try Single-Length Irons?

As a coach, I don't believe in a "magic bullet" for golf equipment. The right clubs are the ones that give you the most confidence to hit your best shots. So, who is the ideal candidate for a one-length set?

This system might be a great fit for you if:

• You Are a Beginner: If you're just starting, you have no bad habits or previous muscle memory to unlearn. Starting with a simplified system where you only have to master one setup and one ball position for all your iron shots can dramatically speed up the learning curve.
• Your Primary Struggle Is Inconsistent Ball-Striking: If you find yourself constantly hitting shots thin or fat, and you feel lost trying to remember the right setup for each club, the simplicity of one-length could be a game-changer. It eliminates many common setup faults by design.
• You Are an Analytical Golfer Who Loves to Tinker: If you're like Bryson and enjoy the technical side of the game, and you're willing to commit to the process of getting properly fitted and dialing in your set, the potential consistency gains can be very rewarding.

You might want to stick with traditional-length irons if:

• You Already Have a Solid, Feel-Based Short Game: If your wedge game is a strength and you rely heavily on the feel and versatility of your scoring clubs, moving to longer wedges might do more harm than good to your scores.
• You Are a Low-Handicap Golfer Who Is Already Consistent: If you already strike your traditionally-lengthed irons well, the benefit of switching likely won't outweigh the significant adjustment period required to get comfortable.

Ultimately, the most important piece of advice is to get properly fitted. Don't just buy a set off the rack. A qualified club fitter can help you test single-length irons against your current set, analyze the launch monitor data, and determine if the system truly helps your game.

Final Thoughts

Bryson DeChambeau brought single-length irons into the spotlight, proving that a different approach to golf equipment can succeed at the highest level. The system’s core promise is simplifying the golf swing by using one setup for every iron, offering a massive potential boost in consistency, particularly for beginners or high-handicappers. However, these benefits come with the trade-offs of a challenging adjustment period and potential issues with feel and gapping in the scoring clubs.
