What is Ring Size?

Ring size is a measurement used to represent the circumference (or occasionally the diameter) of jewelry and smart rings.

Ring size charts represent the sizes of rings from A to Z where A is the smallest ring size while Z is the largest ring size. Each letter shows the diameter of the ring which could be in cm or mm.

Some Jewelers have printed ring size charts and international ring size conversion charts, when any buyer wants to order the rings through an online store. However Some online stores and retail shops offer a ring sizer which is used to measure the ring size accurately.
