The ring size refers to the finger diameter of the wearer, usually expressed in millimeters (mm). When choosing a ring, the correct size is very important. Too tight or too loose rings will affect the comfort and effect of wearing.

When measuring the ring size, you can measure the finger circumference of the wearer with measuring rings, strings, paper strips and other tools, and then compare the ring size table to determine the appropriate size. Different countries and regions may have slightly different ring size standards, so when buying a ring, you need to choose the size that suits you.

When choosing a ring, besides the size, the wearer's hand shape and preferences should also be considered to ensure that the selected ring is comfortable and suitable. If you are in doubt about the size of the ring, you can consult a professional jewelry store staff.
