How to measure your ring size

  • With a ring: measure the inner diameter of a ring you already own and compare it to the chart.
  • With a measuring tape or a strip of paper: wrap it around the finger where you want to wear the ring. Mark the spot where the ends meet and measure the length — that is your finger circumference.

Compare your circumference to the chart above to find the right size. If you are between two sizes, we recommend choosing the larger one.

  • Tip: measure your finger in the evening, when fingers are slightly more swollen, for a more accurate fit.
