Physiotherapists recommend the following method of determining the correct height for a walking stick.
The walking stick user should stand upright, in the type of shoes they usually wear, with their arms hanging naturally by their sides. Another person should turn the walking stick upside down, so that the handle is resting on the floor. Positioning the stick next to the user, make a small mark on the shaft of the stick level with the bump at the bottom of the wrist bone. Using a small saw, cut the stick at this point. This will mean that the user's arm will be slightly bent when they hold the stick.
