You need a strip of paper or thread, a pen and a ruler.
- Wrap the strip snugly around the base of the finger you want to wear the ring on.
- Mark where the strip overlaps.
- Lay it flat and measure from the end to the mark in millimetres.
- Match the measurement to the circumference column in our Size Guide.
Tips for an accurate fit
- Measure at the end of the day, when fingers are slightly larger.
- If your knuckle is wider than the base of your finger, measure both and use the larger number.
- Between two sizes, choose the larger one.
Many of our rings are adjustable; the product page says so under Specifications.
