Sizing Chart

The best way to figure out your ring size is to visit your local jeweller to have your sizing done professionally and accurately.  If this is not feasible, use the ring sizing guide below to help you decide which size is best for you.  

This can be done in two ways:
  • Either measure in mm the INSIDE diameter of a current well fitting ring by placing a ruler across the centre of the ring at the widest part and measuring. Please see below:
  • Wrapping a string firmly but comfortably around your finger exactly one time, mark how much string you use and measuring the length of this string across a ruler to figure out the circumference. 
Next, compare the measurements of either the inside diameter or circumference to the chart below to figure out your ring size.
