Measure
Measure your finger or a ring that already fits comfortably.
Find your ring size with our UK, US and EU conversion chart, plus simple guidance for measuring at home and choosing a comfortable fit.
Measure your finger or a ring that already fits comfortably.
Use the chart to compare UK, US and EU sizing.
Select the size that gives a secure but comfortable fit.
For the best result, measure more than once and avoid measuring when your hands are unusually cold or warm. A ring should feel secure without being difficult to remove.
If you already own a ring that fits the correct finger, compare its size or inside measurement with the chart.
Measure around the base of the finger without pulling the measuring material too tightly.
Finger size can change slightly through the day, so repeat the measurement before choosing your size.

Two rings with the same nominal size can feel slightly different depending on the width and profile of the band. Wider rings often feel more snug than slim bands.
If the ring is a surprise, use a ring the recipient already wears on the intended finger where possible. Finger sizes can differ between hands and between fingers.
The best choice can depend on the ring style and band width. If you are unsure, contact us before ordering so we can help you check the sizing information for the piece.
No. Resizing options depend on the metal, construction, setting and design. Rings with stones around the full band or intricate detailing can have limited resizing options.
Finger size can change slightly with temperature, activity and other everyday factors. Measuring more than once can give you a more useful indication of your usual fit.
A ring should feel secure but comfortable. It should not feel painfully tight, and it should be possible to remove it without excessive force.
