The Ring Sizer Tool is only available for mobile use, so please make sure you're on a smartphone.

1. Once you open this page on mobile, you will get access to the Ring Sizer Tool. The slider enables you to adjust the size of a circle displayed on your device.

2. Place your ring on your screen, Position it flat and so that the inside of the ring's band aligns with the outer edge of the black circle displayed on your screen. This will ensure an accurate measurement.

3. Use the slider to adjust the size of the circle until it matches the inside diameter of your ring as closely as possible. You can do this by sliding your finger left or right on the slider.


4. As you adjust the circle size, you will notice that a UK ring size and its corresponding millimeter measurement are displayed below the circle. Continue adjusting until you find the UK size that matches your ring, and note the millimeter measurement displayed as if in between sizes, we recommend sizing up.
