Ring Sizing
How to know your ring size
You may be here for a couple of reasons, perhaps our cannon ring or our full moon ring are calling your name - or perhaps you are trying to find a non-complicated way to propose to a loved one and facing the daunting task of making sure it fits.
Have no fear! There are two ways to do this: measure an existing ring or start afresh.
Remember - our finger sizes change throughout the day depending on our salt, alcohol intake, as well as weather. It's best to measure hands when they are warm and at the end of the day to take a 'worst-case scenario approach'.
Option 1: Measure an existing ring
- Select an existing ring that fits the desired finger.
- Measure the internal diameter of the ring (in mm).
- Use the chart below to determine your ring size.
Option 2: Start fresh
- Wrap a strip of paper or string around your finger where you’d like your ring to be.
- Make sure that the paper or string is tight around your finger.
- Mark the length of the string/paper and measure the length in mm.
- Match the length measured with the corresponding size below.
