European ring sizes are used by many European countries, including France, Germany (they sometimes use a system based in ring diameter), Austria, Belgium, Denmark, Sweden and Norway. The sizes are based on the ISO standard, which uses the inner circumference of the ring for their sizes but these don't directly relate to US or UK sizes, which is why we created a free, easy-to-use tool to help you find what the equivalent sizes are.
To use the ring size conversion tool, simply:
- Select the size standard from the dropdown list (it defaults to European sizes on this page)
- Select the ring size
- Then the tool will show you the exact or closest matches in the other size standards and allows you to see the small differences in sizes between the closest matched sizes
