Ring Size Guide

Choose the method that works best for you. Both are equally accurate.

Method 1 — Measure a ring you already own
Place a ring that fits well on a flat surface. Measure the inside diameter in millimetres using a ruler. Match the result to the chart below. This is the fastest method if you own a ring that fits perfectly.

Method 2 — The string (or paper strip) method
Cut a thin strip of paper about 10cm long and 5mm wide. Wrap it around the base of the finger you plan to wear the ring on — go past the knuckle, not just the base. Mark where the strip overlaps. Measure the total length in millimetres. This is your circumference. Find it in the chart below.

• Between two sizes? Go up half a size — a ring that's slightly loose is more comfortable to wear daily than one that's too tight.
• Wide bands (6 mm or more) sit snugger on the finger than a thin band of the same size. Consider going up half a size for any band wider than 5 mm.
• Time of day matters. Fingers are slightly larger in the evening and in warm weather. Measure when your hands are at a comfortable temperature — not first thing in the morning.
• Our engraving is on the inside. Inner text, dates and initials are laser-engraved on the inner surface of the band — this does not affect the fit or comfort at all.
