Determining your ring size can be tricky without the proper tools. Use our Ring Size Conversion chart below to find your ring size in different countries.

The easiest way to determine a ring size is to measure a well-fitting ring that they already have. Take a ruler or tape measure and measure the inside diameter of the ring. So measure from left to right the inside of the ring and do not measure the edge. The number of millimeters is the ring size.

The most accurate way to determine the ring size is to visit a local jeweler and have them measure the ring finger.
