Ring Size Conversion Chart |

This means that we guarantee that your ring will always fit! If after converting your size into the US/Canada size (our size) and you find you are either on a 1/4 or 3/4 size; select the nearest half or whole size below (eg. If you are an 8 1/4, select a size 8. If you are a 8 3/4, select a size 8.5).
