Find your perfect fit.
Getting your ring size right before we begin saves time and ensures your commission arrives ready to wear. Here's how to measure with confidence.
Three ways to measure
Use an existing ring
Find a ring that fits the intended finger well. Lay it flat and measure the interior diameter in millimetres. Use the chart below to find your size.
Wrap with paper
Cut a thin strip of paper and wrap it snugly around the base of the finger you intend to wear the ring on. Mark where it overlaps. Measure the length in millimetres — that's your circumference.
Visit a local jeweller
Any jewellery store will measure your finger with a ring gauge at no charge. Ask for your size in US and EU standards, and let us know both.
Measure at the end of the day — fingers are slightly larger in the evening.
Warm fingers are larger than cold ones. Measure at room temperature.
For wide bands (over 6mm), go half a size up from your standard measurement.
If you're between sizes, we always recommend sizing up — rings can be resized down.
