If you’d prefer to measure for your own stick then this simple guide should give you a good idea of how to get the best result.
In the first instance put on your ordinary walking shoes and stand as naturally upright as possible. Allow your arms to fall to the side with a natural bend allowed at the elbow. Then, using a tape measure, get someone else to measure the distance from the wrist joint down to the ground. This should give you the ideal size for your stick.
Obviously some people require, or prefer, a shorter or longer stick but this should give you a starting point from which to decide upon your personal preferred length.
If it isn’t possible to measure for the stick then a simple calculation can be used to get a rough idea of size.
Convert a person’s height into inches (for example 5’6″ = 66 inches.) Then simply divide this number in half to get the size of stick, in this example 33 inches.
