HOW TO MEASURE
Measure an Existing Ring
MOST ACCURATEPlace a ring that fits comfortably on a flat surface and measure the inner diameter in millimetres. Match your measurement to the sizes above.
Measure Your Finger
EASY & CONVENIENTWrap a thin strip of paper or string around your finger and mark where it overlaps. Measure the length in millimetres to determine your circumference, then match to your size.
