Ring Size Guide: Find Your US Ring Size
Before choosing a ring, compare your measurements with the sizing information on its product page. Browse our Rings collection and check each design individually.
Measure a ring that fits
- Choose a ring that fits the same finger you plan to wear the new ring on.
- Measure straight across the inside opening in millimetres, excluding the metal band.
- Compare this inside diameter with the product’s measurements or size chart. Diameter and circumference are different measurements.
Check the sizing system
US, UK and European size labels are not interchangeable. Use the sizing system stated on the product page. If a conversion or measurement is missing, contact us before ordering rather than guessing.
Wide bands and adjustable designs
Band width and shape affect how a ring feels. Check any fit notes, and do not assume that every adjustable ring fits every finger. Review the listed adjustment range where provided.
Shopping for a gift
A well-fitting ring worn on the intended finger is a useful reference. If you do not know the recipient’s size, confirm it before selecting a fixed-size design.
