How to fit kids for golf clubs:
Choose golf clubs for kids based on height and ability. Poor fitting, heavy golf sets can lead to swing problems that may be difficult to correct. Properly fitting clubs allow a child to swing freely and naturally.
Kid's golf clubs should have heads which are much larger and lighter and a composite shaft as opposed to a heavy steel shaft - this makes the junior golf club sets lighter and will provide more power for greater distance.
To accurately measure kids for golf clubs, have them wear a pair of tennis shoes and measure from the floor to the top of their head.
For the best fit, measure your child's "closed fist" knuckle-to-ground measurement. This is the standard on which most manufacturers base their sizing for junior golf sets.
