Use the section routes to render the interactive ring size experience.
Convert ring sizes clearly
If you know the country where the size was originally given, choose it first. If you only know the size and not the country, leave the first field blank and enter the size anyway. We will show all likely matches, highlight the source system in green, the conversion country in blue, and the best matching row in yellow.
How to use measurements
Enter the inside diameter or inside circumference in millimetres and we will show the closest ring size conversion.
Measuring your size with a ruler, paper, or rope is not 100% accurate. Please ensure that you measure your ring size at a professional jeweller whenever possible.
