Don't know your ring size? No worries :)

Follow any of these easy instructions to find out.
.

OPTION 1

Place a ring that fits your finger well on top of a ruler, and measure the inside
diameter (widest part of the circle) in millimeters.
Then go to the chart below and find the closest equivalent in US size.
For example: If diameter is 17mm then size is 7.

OPTION 2

Use a strip of paper or a string and wrap it around the base of the intended finger. Then mark where the paper/string overlaps. Place it on top of a ruler and the length you measured in millimetres is the circumference of your finger.

Then go to the chart below and find the closest equivalent in US size.
For example: If circumference is 56mm then size is 8.
