Tips when sizing:

  • Cold weather can shrink your fingers up to half a size, so make sure they’re warm.

  • Measure your ring finger size 3 to 4 times for the most accurate reading.
  • If the measurement falls between sizes, choose the larger size.

How to find ring size for someone else - how to measure using a ring

1.Use an existing ring that fits correctly on the finger that you want to measure.

2.Use the printable ring size chart and match the inside edge of the ring to the correct diameter shown. 

3.You can also separately measure the inside edge of the ring, in millimeters (mm) and use that size to determine the correct ring size based on our ring size chart.

  • Be sure to account for the width of bands or “stackable rings”
  • Engagement & Wedding Bands are worn on the left-hand ring finger.
  • Fashion Rings can be worn on any finger on either hand.
  • Engagement & Wedding or Fashion rings should fit comfortably and be snug enough to stay on but loose enough to fit over your knuckle.
