How long should your golf clubs be if you are taller or shorter than average?
Probably standard. Whatever that is. It used to mean a 43"
but now it might mean a 44.5" one.
There are a number of methods to determine whether you should use
overlength clubs. One is to measure the height of your fingertips.
27" would be standard, with the club length changed 1/4 to 1/2 the
difference. E.g. if your fingertip height is 28", add 1/4 to 1/2
inch. Another is to use the height of the top of your hand (at the
seam with the wrist),with 34" being standard, and the adjustment
1/4 of the difference from standard.
