We want to ensure that you find the perfect fit for your ring. To make it easier for you, we've put together a comprehensive guide to ring sizing.
Option 1: Measure an Existing Ring
Measuring an existing ring can be a quick and easy way to find your ring size. Here are the steps to follow:
- Choose a ring that fits the finger on which you want to wear your new ring.
- Measure the inside diameter of the ring in millimetres (mm). You can do this by placing the ring on a ruler and measuring from one inner edge to the opposite inner edge.
- Make a note of the diameter measurement in mm.
- Use the chart below to find your corresponding size in US sizes.

Note: If the diameter measurement falls between two sizes, it's best to choose the larger size to ensure a comfortable fit.
Option 2: Measure the Finger
If you don't have an existing ring to measure, you can measure your finger instead. Follow these steps:
- Wrap a piece of string or a strip of paper around the base of your finger where the ring will sit.
- Mark the point where the string or paper overlaps.
- Measure the length of the string or paper in millimetres (mm).
- Use the chart below to find your corresponding size in mm and US size based on your finger circumference.
