Ring size guide and conversion chart
If you want to know the size of your ring finger, we have made things simple. Here is your feel-safe guide to finding your ring size from the comfort of your home.
Take a piece of string or a strip of paper. Wrap it around the base of your finger (not too tight, not too loose).
Mark where the ends meet. Use a ruler to measure the length in centimeters (cm).
Check the table below and match your measurement with the “Circumference (cm)” to find your ring size.
