To know the size of your ring you can use either of the following two methods:

(1) Do you have a ring that already suits you? Let's measure its DiameterCool! Measure the inside diameter of your ring and convert the diameter obtained to the corresponding size from the table above. In case of being between two sizes, always choose the larger one.


(2) Don't have a ring on hand? Measure your ring size by circumference of your finger. You will need some string or thread, a ruler, and a pen. Surround the base of the finger with the string and measure the length of the resulting string. If the diameter falls between two ring sizes, always choose the larger one.

Use the table above to convert the circumference or diameter to the European size.
