Please Follow The Finger Circumference Measuring Method
Tools Needed: a strip of paper or thin string, a pen, and a ruler
Wrap the strip around the widest part of the finger you plan to wear the ring on.
Mark the point where the strip meets itself while wrapping around the finger's widest part.
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.)
