How to determine your ring size
If you plan to buy a ring for yourself or someone else, knowing the right size is essential. You can calculate the circumference of your finger yourself by wrapping a rope around your finger and measure the number of millimetres with a measuring tape. The length of the ribbon is the circumference of your finger. Check the table to see which ring size best fits your circumference.
