Find Your Ring Size

Measuring your ring size at home is easy — all you need is a ring that fits and a ruler.

How to measure your size at home:
  1. Take a ring that fits the finger where you'll wear your new piece.
  2. Place the ring flat over a ruler that includes millimeter markings.
  3. Measure the inner diameter — from one inside edge across to the other in millimeters.
  4. Match your measurement with the size chart below to find your EU size.

Tips for accurate sizing:

  • Measure at the end of the day — when fingers are slightly larger.
  • Avoid measuring when your hands are cold.
  • If you're between two sizes, choose the larger one.
  • Thicker bands sit tighter — size up in those cases.
