Regarding rings French sizes correspond to the inner circumference of the ring in millimeters.
An ideal size is one that allows the ring to pass the knuckle with light to moderate resistance.
If you are between two sizes, choose the more fitted one.
To determine a size precisely, there are two solutions:
1. Go to a jewelry store to have your size determined by a professional
2. Order a ring sizer to determine your measurements at home. Order our ring sizer by clicking here
We do not recommend any other tricks, such as wrapping a string around your finger, which is not precise.
