Use the chart below to find your ring size or The perfect fit starts with knowing your size. We use British & Australian ring sizing at UbyKate, and there are a few simple ways to find yours before placing your order.

Option One: Measure a ring you already own
Measure the inside diameter of a ring that fits the intended finger, in millimetres. Match your measurement to our ring size chart.

Option Two: Measure your finger
Wrap string or paper snugly around your finger, mark where the ends meet and measure the length in millimetres. This method is less precise, so we recommend confirming your size professionally.

Option Three: Order a complimentary ring sizing kit
For a more reliable at-home measurement, order your free UbyKate ring sizing kit.
