Please Follow The Finger Circumference Measuring Method

Tools Needed: a strip of paper or thin string, a pen, and a ruler

setp1

Wrap the strip around the widest part of the finger you plan to wear the ring on.

setp2

Mark the point where the strip meets itself while wrapping around the finger's widest part.

setp3

Remove the strip, lay it flat, and measure the length between the marks with a ruler – this is your finger circumference.

(Body weight is for reference only – please rely on your actual measurement.)
