Introduction To Iron Fitting

Properly-fit golf clubs can enable any golfer the opportunity to maximize his or her performance and optimize the quality of the equipment that they play. Custom options also ensure a great enjoyment of the game. However, most equipment brands do not design or manufacture golf clubs to a universal set of standards or measurement techniques.

It's important to consider the following key points when selecting a customized iron set:

  • Height
  • Age
  • Handedness
  • Physical Limitations
  • Weight
  • Gender
  • Current skill level (if applicable)
  • Shot Characteristics (from a Right-hander’s point of view)

golf club length

The primary indicators of proper club length are a combination of the player's height and ability. Height alone (or the length of one's arms) does not automatically determine the proper length of a golf club tall individuals do not necessarily need longer clubs and shorter individuals do not necessarily need shorter clubs.

The ability of a golfer to strike the ball consistently on the sweet spot is the most important factor when determining a club's ideal length.


  • Wearing street or golf shoes, stand upright with your arms relaxed at your side.
  • Make a fist with the right hand (left hand for left-handed golfers), measuring the distance from the end of your knuckles to the floor.
  • Cross reference your height and knuckles-to-floor measurement (at right) to determine your appropriate club length.
  • Most players' measurements should fall within the average range of measurement(noted in blue)
  • If possible, testing an iron in the appropriate specs is ideal for confirmation of these measurements.
    • A minimum of five shots should be hit to gauge ball striking and overall contact.
    • Inconsistent contact might be due to poor posture at address and impact.

If a player’s clubs are too long, he or she will tend to:

  • Choke down on the club
  • Stand too tall with little or no knee flex, leading to an inconsistent action through the ball.
  • Hold his/ her hands too high at address.
  • Favor moving his/ her weight into the heels at address, a common swing flaw.
  • Lift up through impact, promoting an inconsistent strike.
  • Hit an unusual number of “fat” shots with the irons.
  • Struggle with tempo and balance throughout the swing.

If a player’s clubs are too short, he or she will tend to:

  • Grip the club past the butt end of the club.
  • Bend too much from the waist at address.
  • Address the ball with the heel of the club, the portion of club closest to the shaft.
  • Fall into the ball through impact.
  • Hit thin or low shots with the irons.

Lie Angle

Lie angle is the position of the club in the address and impact position, and should be considered in conjunction with club length.

In general, each 1/2” change to the standard length of a golf club equates to a 1-degree change to the lie angle – if lengthened, the lie becomes more upright; if shortened, the lie becomes flatter.


  • As a general rule, lie angle is best determined on a lie board, using lie angle tape.
  • An alternative is to determine the lie angle by analyzing the club at address – the “address position fitting method”
    • Determine the center of the club by measuring the distance between the scoring lines on the clubface and dividing by two.
    • Put a light pencil mark along the bottom of the club at this central point. This determines where the iron should sit if the lie angle is correct.
    • Assume your address position.
    • While in the address position, have someone slide two pieces of paper under the club, from the heel and the toe, as far as they will move towards the center of the club.
    • The gap between these pieces of paper marks the point at which the club is touching the ground.
    • If too upright, the club will bottom out closer to the heel of the club.
    • If too flat, the club will bottom out closer to the toe.
    • If the lie is correct, the papers will indicate that the club is touching the ground at or near the pencil mark.
    • Repeat this test for all irons in your bag to ensure a reliable assessment of your lie angle.

Grip Size

The correct grip size enables a player to maintain proper contact with club and to execute shots with greater ease. The most important benefit of a properly-sized grip is the ability to consistently square the clubhead at impact.

The ability to consistently square the clubface is directly proportional to the action of the wrists throughout the swing. If the grip is too large, the wrists can't hinge properly throughout the swing. Too small, and the wrists become overactive and difficult to control.

Small or large hands are not necessarily the only factors to consider when determining grip size. The comfort of the player and his or her ability to maintain consistent connection with the club are vital.


  • Begin with a standard grip. Assume your normal grip with both hands on the club.
  • The fingertips of the top grip hand (the left hand for right-handed players and the right hand for left-handed players) should lightly tough the pad of the hand.
  • If the fingers begin to overlap the palm, a larger grip is required.
  • If the fingertips do not touch the pad of the hand, or a sizeable portion of the grip is visible between the fingertips and the pad of the hand, a smaller grip is required.
  • Players suffering from physical limitations such as arthritis, joint problems, and carpal tunnel often require larger grips.
  • Golf glove size should be used in conjunction with a basic grip test – it is not a reliable measure of required grip size on its own.
  • For players preferring a grip between standard and midsize, consider increasing the number of wraps of tape underneath a standard grip. Each additional wrap of tape will increase the grip size by 1/64". Two wraps will increase grip size by 1/32". Three additional wraps of tape closely mirrors the feel of a midsize grip.
