As most of the wedding rings on our site are wide please ensure you use a wide ring gauge when getting your finger sized. If you are using a narrow ring gauge then compensate by going at least a 1/2 size bigger to accommodate the wider ring.
Ring sizes in the United States (US) are based on a numbering system from 1 to 15 with 1/2 sizes in between. One half size in the US system is roughly equivalent to one whole size in the British (UK) System which are measured by alphabetical letter A-Z. The sizes are also evenly spaced with 1/2 sizes in between. European sizes are based on the circumference measurement of the ring in millimetres. The more general European system of ring sizes use the inner circumference (in mm) minus 40.
A really good fit is very important because you'll be wearing your new ring for many years to come so please ensure you get your finger measured correctly.
