What Size Am I?

1) Cut a strip of 4mm paper or a piece of non stretchy string.

2) Wrap the paper around your finger until it feels comfortable and mark where the two ends overlap.

3) Check that the paper or string slips over the knuckle.  

4) Measure the distance between the two marks and compare to the below table (Diameter = UK size)

5) If the ring is a wide ring then we would normally advise that you add between a half to a full size extra.
