For our standard non-adjustable rings, use the chart below to find the closest UK size. If you already own a ring that fits comfortably, measure straight across the widest point of the inside of the ring to find its inside diameter. Alternatively, measure around the base of your finger to estimate the inside circumference.
Size: Inside Diameter / Inside Circumference
- H: 14.8 mm / 46.2 mm
- I: 5.2 mm / 47.4 mm
- J: 15.6 mm / 48.6 mm
- K: 16.0 mm / 49.8 mm
- L: 16.4 mm / 51.0 mm
- M: 16.8 mm / 52.2 mm
- N: 17.2 mm / 53.5 mm
- O: 17.6 mm / 54.7 mm
- P: 18.0 mm / 56.0 mm
- Q: 18.4 mm / 57.3 mm
Note: Ring fit can vary slightly depending on the width and design of the band. Wider bands may feel more snug than fine bands, so customers between sizes may prefer the larger size.
