Ring Size Chart
Our rings use US sizing. Not sure which is yours? Measure in under a minute with either method below.
Option 1 — The String Test
- Wrap a 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 mm.
- Match that number to the Circumference column below.
Option 2 — Use a Ring You Own
- Take a ring that already fits the right finger.
- Measure the inside diameter across in mm.
- Match it to the Inside Ø column. Between two sizes? Choose the larger.

Tip: measure at the end of the day when fingers are warmest, and aim for a snug fit that slides over your knuckle. Wide/comfort-fit bands can feel tighter — size up half a size.
