There are three ways to find out the correct ring size for you: you can pop into the shop to have your size measured, you can measure a ring you already own using the chart below as reference,
or you can order an Inplico Ring Sizing Kit.

Measuring a Ring You Own

If you already have a ring that you wear on the finger you are hoping to get a new ring for, 
you can measure that ring to get the size for the new ring. Take a ruler 
with millimetres on it and measure the internal diameter of the ring.
Use the chart below as reference to work out the correct size for you.
