Ring Size Guide
Please be sure to use only our sizing guides to help you find the right fit for our rings. You may find the ring comparison guide as an attachment at the end of this article.
You may measure the circumference of your selected finger and use the table below to determine your size. You can wrap a string or cable around your finger to approximate its circumference.
How to Measure
- Wrap a soft tape, string, or paper around your finger
- Fit snugly, not tight
- Measure the length in millimeters (mm)
- Match it with the inner circumference below
