## Length fitting

There are two ways to fit for length – a static fitting and a dynamic fitting.

### Dynamic Length Fitting

A dynamic fit, one that is performed while the player swings the club, is more precise. The goal is to find the length that creates the best athletic set-up, the best motion, and that maximizes distance and accuracy. There are no calculation – just swing trials, observations and corrections.

### Static Length Fitting

Static fitting uses measuring techniques and some calculations. It’s a less precise, but it provides a player with basic comfort in stance and posture in quick and easy way. It is also the good starting point for further swing analysis and dynamic fit.

There are several approaches to static fitting. They are all based on differences in golfers’ body dimensions. All the measurements needed to perform are shown in the picture below.

### Static method no 1 – Producers charts

A number of producers publish charts that suggest the necessary correction of the club length depending on the golfer’s height and the distance from his (her) wrist to floor (WtF). Results of using this method are rather “conservative” in changing length. The most likely reason is that the length changes greater than 1 inch (2,5 cm) make significant differences in swingweight and MOI. Compensation of these changes would require the production of more different heads, which of course is more complicated for manufacturers. Nevertheless, the calculator below gives the typical values proposed in different manufacturers’ tables.

### Static method no 2 – Golfer’s height

This is another method proposed by producers. It simply takes the difference between the height of a particular golfer and a “standard golfer” *, and use a 1 inch change in club length for each 5 inches of height difference. This method is also rather “conservative” and can only be used for adult golfers with classically proportioned bodies.

### Static method no 3 – Fingertip height

Calculations in this method are based on the distance between the floor and the golfer’s fingertips when he (she) stands erect with arms hanging straight – see FtF at the picture. The change in length depends on the difference between the FtF of a particular measured golfer and a “standard golfer” *. Different authors say about different ratios of changes: from ¼ inch up to one inch for each full inch of FtF. In the calculator below we use ratio of ¾ which is in our opinion the most appropriate coefficient.

### Static method no 4 – Anthropometry

This method is based on average body proportions and bending angles that occur at positioning the golfer’s body when addressing the ball. The calculations are developed by us and it would be helpful to get any feedback from readers who would try to apply them.

*) “standard golfer”  is 178 cm (5’10”) tall for man and 165 cm (5’5”) for woman

Results of all 4 methods are shown in the calculator below. It displays the recommended corrections of length in relation to the factory “standard” length. There are 4 different approximations and users are free to use any of them at their own discretion and at their own risk.
