What Pro Golfers Use One Length Irons?

You’ve seen him on TV, the one pro who stands out not just for his powerful, unique swing but for his seemingly identical set of irons. This naturally leads to the big question: what pro golfers use one-length irons? The short answer is Bryson DeChambeau, almost exclusively. This article will not only confirm which pros use these unconventional clubs but also explain the thinking behind them, why more tour players haven't followed suit, and - most importantly - help you figure out if they might be a good fit for your own game.

The Exclusive Club: Pro Golfers and One-Length Irons

When you boil it down, the list of professional golfers on major tours using one-length irons is incredibly short. The conversation begins and, for the most part, ends with one name: Bryson DeChambeau.

Bryson isn't just a user, he's the chief evangelist and co-developer of the modern one-length concept alongside Cobra Golf. His entire approach to golf is rooted in science and simplification. He treats the golf swing not as an art form but as a physics problem to be solved. For him, using irons that are all the same length (specifically, the length of a standard 7-iron) eliminates countless variables that trip up most golfers.

You might occasionally hear of a player on a developmental or smaller tour giving them a try, but none have committed to them with the conviction or achieved the level of success that Bryson has. He remains the sole, high-profile example on the PGA Tour. This is significant. It tells us that while the concept is compelling, it hasn’t sparked a revolution among the world's best players. To understand why, we need to look closer at what makes them so different.

Why Did Bryson Switch? The Logic Behind Simplicity

To understand why Bryson uses one-length irons, you have to understand his philosophy. He famously bases his swing on an old, highly technical book called "The Golfing Machine," which promotes a single-plane swing. The idea is to move the body and club on one consistent angle throughout the motion.

Traditional irons throw a wrench in that idea. Think about it:

• Your 4-iron is long. You stand further from the ball, your posture is more upright, and your swing path is naturally flatter or more rounded.
• Your pitching wedge is short. You stand closer, you're more bent over, and your swing path is much more upright or steeper.

That means for every iron in your bag, you need a slightly different setup, a slightly different ball position, and a slightly different swing plane. For Bryson, that complexity was an unnecessary variable. He and Cobra worked to create a set where every iron - from the 4-iron down to the wedges - is the same length, has the same lie angle, and is the same total weight.

The Goal: One Swing to Rule Them All

The benefits, at least in theory, are profound. With one-length irons, you establish:

• One Setup: Your stance width, distance from the ball, and posture are the same for every single iron shot.
-

No more moving the ball- to back- or mid-stance. You find the one spot that works and stick with it. -

You are grooving the exact same motor pattern, the same feeling, on every iron swing. Your 5-iron swing is your 9-iron swing.

By streamlining everything, Bryson can focus entirely on executing one perfect, repeatable motion. It turns a game of constant adaptation into one of pure repetition.

If It's So Simple, Why Don't More Pros Use Them?

This is the an important question. If one-length irons offer radical simplification, why hasn't every pro followed Bryson’s lead? There are a few core reasons that matter far more to a tour pro than an amateur.

1. Lifelong Feel and Training

Tour professionals have been playing with variable-length irons since they were young children. Their sense of feel, distance control, and creativity is built on the foundation of a short shaft for short shots and a long shaft for long shots. Their minds and bodies are finely tuned to produce different shots with different tools.

• The Problem with Long Irons: Handing a pro a 4-iron that is the length of a 7-iron can feel strange. Although modern head designs help get the ball airborne, many pros feel they lose the power and piercing trajectory that comes a longer shaft. Psychologically, it feels like they’re giving up distance.
• The Problem with Short Irons: This is arguably the bigger hurdle. A player's "scoring clubs" (_8-iron, 9-iron, wedges_) are all about touch and finesse. Making those clubs longer - all the way to a 7-iron length - can feel incredibly clumsy. Imagine trying to hit a delicate, 40-yard pitch-and-run shot with a club that feels awkwardly long. It robs them of the precise control they’ve spent a lifetime developing. Hitting high, soft flop shots or low, spinning checkers becomes a completely different skill.

2. The Risk of a Complete Overhaul

For an elite player whose livelihood depends on consistently performing, changing their entire iron set is a monumental risk. It's not just swapping out one club, it's relearning an entire facet of their game. They would require thousands of hours of practice to recalibrate their distance control, shot-shaping abilities, and short an iron gapping. Most aren't willing to risk a bad season or two for a concept that has yet to be widely proven at the highest level beyond one very unique player in the field.

3. Specific Trajectory and Gapping Needs

Pros are obsessive about hitting certain "windows" and yardages. They want to be able to flight a 5-iron low under the wind or hit a 9-iron that flies very high and lands soft. While one-length sets are engineered with varying head weights and CG placements to create consistent distance gaps, some pros feel they lose a degree of workability. They’ve perfected the art of manipulating ball flight with specific clubs, and forcing every iron into the same swing framework might limit their shot-making toolbox.

The Real Question: Could One-Length Irons Be Good for *You*?

Here’s where the conversation gets interesting. The very reasons most pros avoid one-length irons are the same reasons they could be fantastic for many amateur golfers.

While a pro is focused on refining an already-elite skill set, most amateurs are still battling the fundamental challenge of consistency. That’s where the power of simplification truly shines.

The Amateur’s Advantage

1. Incredible Simplicity in Setup

Forget the endless mental checklist before every shot. Is the ball forward enough for this 5-iron? Am I standing too close for this 9-iron? With one setup for every iron, you remove layers of potential confusion and doubt. You just take your stance and swing, allowing you to develop a consistent rhythm and routine.

2. Better, More Efficient Practice

When you head to the driving range, every swing you make with an iron is reinforcing the exact same fundamental movement. You're not practicing seven or eight slightly different moves, you're ingraining one. This can dramatically speed up improvement because you concentrate your efforts on a singular feeling and motion. For new golfers, it presents a much faster way to learn the basics of a consistent iron strike.

3. Potentially A Greater Consistent Strike

The number one killer of good shots for amateurs is an inconsistent strike - toe shots, thin shots, heavy shots. A huge cause of this is an inconsistent setup and swing plane from club to club. By forcing you into the same great posture and ball position every time, one-length irons give you a much better chance of repeatedly finding the center of the clubface.

Who Are One-Length a Good Fit For?

• Beginners: Learning the game with one-length irons is a fantastic idea. You can build a solid, repeatable swing from the ground up without the added confusion of variable-length clubs.
• High-Handicappers: If inconsistency is your biggest enemy, these clubs are designed to combat it head-on. By simplifying the process, you have fewer swing thoughts and can focus more on the target.
• The Analytical Player: If you're someone who likes things to be logical, repeatable, and system-based (sound a lot like Bryson?), the one-length concept will likely appeal to your brain.

And Who Should Maybe Steer Clear?

• The "Feel" Player: If you’re a long time player with solid golf skills and rely heavily on your feel and touch around the greens and already trust the feel of your variable-length iron set, the switch could be jarring and unproductive. Messing with the length of your well-loved, scoring clubs and delicate wedges can be a risky move.
• The Happy Wedge Player: If your short iron and wedge game is currently the best part of your skill set, lengthening those scoring clubs is probably not a step in the right directly. Improving something else should should take priority first!

Final Thoughts

So, the long and short of it is that Bryson DeChambeau is the primary pro championing one-length irons, using them to craft a simple, repeatable swing. While most of his peers stick to traditional clubs due to a lifetime of developed feel and muscle memory, the power of a standardized method remains a huge draw for amateur players who want more consistency and fewer things to worry about over the ball.
