How to find your ring size
At home, start by measuring the inside diameter in millimetres of a round ring that fits the same finger comfortably. Confirm the product’s sizing system before selecting a size, and have the fit checked separately for a wide band.
Updated: 2026-10-30How do you measure at home?
Place the ring on a flat surface. Measure across its centre from one inner edge to the opposite inner edge, excluding the metal. This method needs a fully round ring. Record the millimetre measurement and share it with the product code.
How should the ring fit?
It should pass over the joint and sit comfortably where you wear it. For a wide band, ask for a fitting with a gauge of suitable width.
Which size number should I choose?
Our rings are offered in size numbers 8 to 28. If you are unsure, send us the inside diameter you measured (mm) with the product code before choosing a number, and we will confirm the right size with you.
