Ring Sizing
Find your size.
Place a ring you own on screen, or enter measurements you already have. We'll give you the right size in US, UK, EU, and Japan systems.
Calibrate
Match the gold shape to a real object.
Place it flat against your screen, then drag the slider until the gold shape matches its width exactly.
Measure a ring you already own.
- Take a ring she wears on the same finger.
- Lay it flat against the screen.
- Drag the slider until the gold circle sits exactly inside the ring.
- Read your size below.

Tip 1
Measure at the end of the day
Fingers swell slightly through the day. Measuring in the evening gives the most reliable resting size.
Tip 2
Warm, not cold
Cold fingers run a half size smaller. If your hands are cold, hold them under warm water for a minute first.
Tip 3
Wide bands run tight
Bands wider than 4mm need to go up a quarter or half size. Ask us if your ring is wider — we'll adjust.
