Help
Wrap a thin strip of paper around the base of the finger you'd like to wear your ring.
Mark where the paper overlaps, then measure the length in millimetres using a ruler.
Match your measurement with the MM or EU column in the size guide above to find your perfect size.
If you're between two sizes, we recommend choosing the larger size for a more comfortable fit.
If you're still unsure, don't hesitate to contact us—we'll be happy to help you find the perfect size before you place your order.
