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.

Return Policy

Fully try-out our golf clubs at your home course and at your convenience for a full month.

To our knowledge we are the only golf club manufacturer in the entire industry who offers a full money-back return policy on golf clubs after they have been played which should tell you volumes about our commitment to our customers.

A return authorization must be obtained before we can accept a return of merchandise. Contact us for this authorization on-line through the Contact page of this website. Shipping/handling charges are not refundable. All contents listed on the original Packing Slip must be included for a full refund. Return shipping charges are the responsibility of the customer. Our return policy is only valid once per customer. Any alterations to the original golf club voids this policy.

Also, be sure to make clear that you (the shipper) are responsible for all shipping charges and any brokerage/storage/handling/duties and taxes incurred. We will not accept any return package where a payment is due - the shipment will be returned to you at your cost. Any charges incurred by us will be deducted from your refund.

Limited Warranty

We warrant our golf clubs to be free of defects in material and workmanship for a period of one year following the original ship date. We will, without charge to the original purchaser, repair or replace the club if it proves to be defective during normal use within this period (normal use does not include misuse or abuse and the associated damages ie: dents on the top, side, rear, or sole of a wood club-head). This does not cover grip or cosmetic wear and tear due to normal usage. Any alterations to the original golf club voids this warranty.

After some practice I am staying in play much more. Does take some getting used to, but worth it.

Original 1 Iron golf irons

Just received my irons and following the recommendation of go to the range several times before playing a round of golf. I must say they feel great when hitting the ball (even range balls) Club feel is very important to me and these are superb. I look forward to playing golf on the course with them.

Used/Demo 1 Irons

Dicks S.G.g.g. (New York, US)

At first I was skeptical, wondering if loft alone was enough, but my loss of yardage in my long irons is negligible. The wedges fly super high and land really soft. And the mid to short irons are wicked. Can’t wait for the driver lol!

I'm a believer

I lost just about all my ability to hit a decent iron shot. I got so desperate I tried a set of hybrids. I hit the ball a little better but I honestly don't believe the clubs fit me all that well. I read most of the info posted on this site and it made a lot of sense even though I was skeptical of the on-line fitting (that's what happened with the hybrids). I ordered the 5-pw used demo set figuring there wasn't much to lose. I followed the plan and went to the driving range the first two days; something I hardly ever do. I got comfortable swinging around my spine and worked hard at hitting the small ball first. The 9 iron felt really great and contact was nearly always center of face and the ball went straight. Not much distance as was warned. Took the clubs to the course and worked on keeping my swing the same with every club. It works. The ball goes where it's aimed and if the swing is good then impact feels great with just a small divot. Distance is not quite what I would like but I'm blaming that on just getting older and sometimes afraid to swing as fast as I can. So far I love the clubs and the results. Each time out gets a little better.
