Measure with a piece of string

Never cut string while it is wrapped around your finger.

  1. Use a non-stretch piece of string or thread.

  2. Cut a comfortable length before bringing it near your finger.

  3. Wrap it snugly around the base of the finger you will wear the ring on.

  4. Mark the point where the string overlaps.

  5. Remove the string from your finger and lay it flat.

Converted centimetre and inch values come from the same approximate millimetre source. They are for display only and add no precision or extra sizes.

Good fit, or pause and recheck

Measure the exact finger and hand that will wear Rune 1, at a normal room temperature. Fingers change slightly through the day, so repeat the measurement to confirm.

Good fit

  • Snug and secure on the finger, without squeezing.
  • Passes over the knuckle without painful forcing.
  • Sits securely without cutting off circulation, and causes no numbness or discoloration.

Pause and recheck

  • You have to force it painfully over the knuckle.
  • It feels tight or constricting, or causes numbness or discoloration.
  • Two readings disagree, or you fall between sizes.

When in doubt, confirm with the forthcoming Pulsyn sizing kit or a professional jeweller.
