Find easily & quickly the size & size of your ring. See table for conversion & correspondence for ring sizes.
The table & photo below will help you convert & match the size of a ring to the size of the unit of measurement used in other countries.
For example, if your ring number in Greece is 44, then in Canada or America it will be 4. If your ring is 48 3/8, then in America it will be 4 3/4.
If you want to find your ring finger size yourself, see the guide“Measuring your ring finger“, or watch the video on the same page.
