Ring Size
Ring size is a measure used to define the circumference (or sometimes, the diameter) of rings that are made of jewels and rings that are smart.
Tools for measuring
A stick that is an analog for sizing rings
Ring size can be determined through a paper, plastic, or metal ring sizer (as gauge) or by measuring the inner diameter of the ring that already fits.
Ring sticks can be used to measure the inner diameter of rings. They are typically made from delrin, plastic or wood, but may also comprise several materials. Digital ring sticks are used for extremely accurate measurements.
Measuring systems
