Ring Size Guide
The right size makes a ring comfortable for a lifetime. The easiest way to get it right is to visit the studio: we size you with professional ring sizers in about a minute, and we always confirm your size before we make your piece.
Sizing Tips
- Measure at the end of the day. Fingers are smaller in the morning and when cold, and a little larger when warm.
- Mind the knuckle. The ring has to slide over it. If your knuckle is larger than the base of your finger, size for the knuckle.
- Wide bands fit tighter. For bands 6 mm and wider, many people go up a quarter or half size. A comfort-fit band (rounded inside) feels a little roomier.
- Measure the finger you'll wear it on. Your dominant hand is usually slightly larger.
Measuring at Home
- Wrap a thin strip of paper or string snugly around the base of your finger.
- Mark where it overlaps, then lay it flat and measure the length in millimeters. That is your finger's circumference.
- Find the closest number in the chart. If you're between two sizes, choose the larger.
Already have a ring that fits? Measure the inside diameter of that ring, edge to edge, and use the diameter column.

Can it be resized later?
Most gold and platinum rings can be resized later. Eternity bands, with diamonds all the way around, and bands in alternative metals such as tungsten, titanium, cobalt, ceramic, zirconium, tantalum and stainless steel can't be resized, so we confirm your exact size before we make or order them.
