How to Measure Your Finger Circumferenced
You will need: a strip of paper or thin string, a pen, and a ruler.
Wrap the strip around the widest part of the finger you intend to wear the ring on.
Mark the point where the strip overlaps itself.
Remove the strip, lay it flat, and measure the length between the marks with a ruler. This is your finger circumference.
Body weight ranges in the table below are for reference only. Please rely on your actual measured circumference when selecting your ring size.
