Ring size
Measure ring size:
If you do not have a flexible measuring tape to measure the circumference of your finger, use a piece of string, ribbon or a narrow strip of paper that you put around your finger. Make sure you do this fairly precisely. Then you measure the distance with a ruler. That distance is the circumference of your finger.
16 = finger circumference 50mm
17 = finger circumference 53mm
18 = finger circumference 56mm
19 = finger circumference 59mm
20 = finger circumference 62mm
21 = finger circumference 65mm
