How to measure your ring size?

  • With a ring: Measure the inside diameter of a ring you already own and compare it with the table.
  • With a tape measure or a strip of paper: Wrap a tape measure or a strip of paper around your finger where you want to wear the ring. Mark the point where the ends meet and measure the length — this is your finger circumference.

Compare the circumference with the table above to find the right size.

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