RING SIZE GUIDE

HOW TO MEASURE YOUR RING SIZE:

METHOD 1: MEASURE AN EXISTING RING

  1. Take a ring that fits your finger well
  2. Measure the inside diameter in millimeters
  3. Match to the chart below

METHOD 2: MEASURE YOUR FINGER

  1. Wrap a strip of paper or string around your finger
  2. Mark where it overlaps
  3. Measure the length in millimeters
  4. Divide by 3.14 to get diameter
  5. Match to chart below
US Size Inside Diameter (mm) Inside Circumference (mm)
4 14.9 mm 46.8 mm
5 15.7 mm 49.3 mm
6 16.5 mm 51.9 mm
7 17.3 mm 54.4 mm
8 18.2 mm 57.0 mm
9 19.0 mm 59.5 mm
10 19.8 mm 62.1 mm
11 20.6 mm 64.6 mm
12 21.4 mm 67.2 mm

TIPS:

  • Measure at the end of the day (fingers swell throughout the day)
  • Wider bands may fit tighter.
  • When in doubt, size up - rings can be sized down easier than up
  • For made-to-order rings, sizing cannot be changed once production begins

STILL UNSURE? Visit a local jeweler for professional sizing (free at most jewelry stores)
