There are two main methods to determine your ring size.

Method 1:

  • Use a ring that you own that fits you well, and measure the internal diameter.
  • Compare the internal diameter to the ring size guide below and choose the diameter which is closest to your size.

Method 2:

  • Wrap a strip of paper around your finger, like a ring.
  • Mark the spot where the two ends meet and measure the distance with a ruler. Compare this distance to the circumferences below and determine your size by the one that matches closest.
