Ring Size Guide
Not sure of your size? Use one of the methods below to find your perfect fit. If you're still unsure, contact us and we'll be happy to help.
Method 1 — Measure an Existing Ring
If you already own a ring that fits the correct finger, simply measure the inside diameter in millimetres and use the chart below to find your UK size.
Place the ring flat on a ruler.
Measure the inside diameter (from inner edge to inner edge) in mm.
Match your measurement to the table below.
Method 2 — Measure Your Finger
Cut a thin strip of paper or use a piece of string.
Wrap it snugly around the base of the finger you intend to wear the ring on.
Mark where the paper or string meets and measure the length in mm — this is your circumference.
Match to the table below.
💡 Tip: Fingers change size throughout the day — they're larger in the evening and when warm. We recommend measuring at the end of the day for the most accurate fit.
