Instruments for measuring
A stick analogous to sizing
Ring size can be determined physically by a paper, plastic or a ring sizer made of metal (as a gauge) or simply by measuring the inner diameter of a ring that already fits.
Ring sticks are used to determine the inner diameter of rings. They are generally made out of delrin, plastic, wood. They can also contain several types of materials. For precise measurements, digital ringsticks may be used.
