Custom Fitting Single Length Irons

All human beings share the same skeletal, muscle, tendon, and joint functions and from a mechanical standpoint are the same regardless of height or sex. Non-mechanical differences arise in custom fitting however, for instance: the height of a bicycle seat needs to be greater for a taller person than a shorter person even though the mechanical design of the bicycle remains the same. By the same token there is only one true fitting variable in the building of golf clubs and that is club length. Based upon your wrist-to-floor measurement we adjust your club length to correspond to the lie angle of our club-heads in order to ensure a proper fitting.

Wrist-to-Floor Measurement
Taking your Wrist-to-Floor Measurement:
  • The wrist-to-floor measurement should be taken while standing on a hard surface.
  • Wear jogging/gym shoes (not golf shoes).
  • Stand with your back against the wall at strict military attention. Place your shoulders and head against the wall, your feet together, and your arms rigid and straight down at your sides.
  • Hold a pencil in your right hand (right handed golfer). Back your arms against the wall and then take the pencil and make a mark where your left wrist joint hits the wall. Just the opposite for a left-handed golfer.
  • Measure from this mark to the floor.
  • Important: Do not round-up the measurement to the next higher inch increment. For instance, if your measurement is 34 and 7/8″, do not round up to 35″.

One Iron Golf Club Lengths

One Iron Golf Club Lengths - Wrist to Floor Measurements

Very Important:

Do not order based upon what you consider to be your favorite iron (ie: #7 iron), and do not use that corresponding wrist-to-floor measurement when placing your order. When ordering you need to specify your actual wrist-to-floor measurement to ensure a proper fitting. This chart reflects club length based upon our club-head lie angles. Consequently, our fitting process does not apply to any other brand.

For the taller golfer:  based upon your wrist-to-floor measurement you may be concerned that your irons would be a typical #3 or #4 iron club length; however, do not compare your measurement to your current #3 or #4 iron. The lie angles of your “long” irons are much flatter than ours which, at your size, requires you to bend over excessively and reach out for the ball at address. The club head lie angle of our irons is 63.5º which is far more upright and allows you, for the first time, to stand upright and much closer to the ball at address resulting in the ideal upright swing posture and swing plane. The taller golfer benefits the most from our fitting formula since they have never played golf clubs that have even come close to fitting them properly. The result being that they have had to develop a very inefficient posture and swing where they are bent over excessively and reaching way out for the ball with every iron in the bag.

How Does the Wrist-to-Floor Measurement Work?

It is based upon trigonometry. At the point of ball impact in the downswing, your wrist, the ground, and the club-head, form a right triangle. Assuming an ideal swing posture, there is a non-linear mathematical relationship between your wrist-to-floor measurement while standing at attention and your wrist-to-ground distance at ball impact.

The club-head lie angles are known for the irons and fairway woods as well as the length of one side of the right triangle based upon your mathematically factored wrist-to-ground distance at impact. This gives us the measurement of two angles and the length of one side. We then use trigonometry to solve for the hypotenuse or club length. This is somewhat oversimplified as we factor in shaft deflection and numerous other factors. The fitting formula that we developed produces the ideal golf club length for anyone regardless of height or arm length.

Our return policy is only valid once per customer. Any alterations to the original golf club voids this policy.

Why not?

These gizmos just make things a little easier. Nothing to think about.

The Only Choice for Single-Length Lefties

Overall a great experience buying clubs from 1 Iron. I had some questions about switching over the single length clubs and they were all promptly answered by the sales crew.

The driver has been a revelation for me, never before have I hit such consistently straight drives. I lost a bit of distance but I'll take that trade any day. The irons have been great as well; consistent gapping, and much more confidence with the 5 and 6 irons. I'm still getting used to chipping around the green with the longer wedges. The woods have been the biggest adjustment. They are steel shafted and feel quite heavy, almost more like a thick iron. I have hit some terrific shots, but not as consistently as the rest of the set yet. I may look into replacing the 5/7 woods with a 3/4 iron down the road.

When I purchased my set, the gap wedge was out of stock, and when it arrived a week after the rest of the clubs, it had a different grip. The folks at 1 Iron corrected this immediately by sending me the correct grip and offering to cover the cost of having it put on. Fortunately the pro shop at my course did it for free, but the customer service was excellent in this case.

1 Iron really is the only choice for lefties wanting to play single length clubs.

The Retired Guy

Your customer service is stellar. Nothing could be better. When I received the clubs they were packaged with care and respect. I saw no signs of a "rush job". You stated to me that when the iron covers came in you would send them to me. I did not have to call back asking if you remembered the covers. You informed me they would be back in stock in several weeks. Sure enough you advised me they arrived and were shipped out to my address. They arrived this afternoon and all irons are now covered. When I hit the golf ball as I should, the clubs function as described. I am extremely satisfied with the clubs and your customer service. Thank you once again!

Best Clubs I have ever owned

Because of having only one hand (left handed) I was skeptical if I would achieve the desired results. Just as advertised! I am more accurate. I hit my irons and fairway woods are longer. These are without exaggeration the best clubs I have ever known. Now I must try the driver and wedges.

I really like the clubs

I am not sure which combo I purchased but I ended up with 3, 5 & 7 fairway woods, 5-9, PW, & SW.

The fairway woods I really love. I feel they’re much easier to hit than my previous fairway woods. I can’t really compare distance as I was terribly inconsistent with my previous ones.

My irons I also like a lot, but mostly because it’s all the same set up. I really loved my Cleveland Launcher HB iron clubhead shape. I sure wish someone made a full set of hybrid one length irons, but until someone does, these are about the best you can get.

I’ve really enjoyed using the irons for the past few weeks and have no intention of switching back to conventional clubs. I’m still adjusting my set up to find just the best position for me, but I can already tell I’m more reliably able to get the shot right. As a beginner, I really appreciate the repeatability these clubs offer. Again, I can’t really comment on how long they play for me relative to my previous clubs because I’m just not very good and very new to golf. Still, I have not noticed any dramatic difference.

The craftsmanship is very solid. The woods are very attractive with a blueish metallic color. They’re a little smaller than my previous woods but it doesn’t seem to affect my ability to strike the ball.

The irons look fairly plain by modern standards, but they’re nice in their simplicity.

One thing I was pretty skeptical about was the “one shaft fits all” policy here at One Iron, but they feel great.

They’re great clubs. I enthusiastically endorse them.

Vern M. (Miami, US)
Thank you

In a day when customer service is all but gone, and over hyped products that don’t perform as touted I find one iron golf a breath of fresh air. Oh the clubs are awesome

David D. (Indian River, US)

Clubs are very nice looking. love the blue color when the light hits the woods. Nice surprise. Came very quickly well made. Can't wait for spring to try them out.
