Finding Your Ring Size

Measure the finger you are wanting to buy the ring for and compare to the scale below
• Find a piece of non-stretchy string or a strip of paper about 15cm long and 1cm wide
• Wrap it snugly around the base of your finger and mark where the ends meet
• Lay the string or paper against a ruler and measure the length in millimetres
• Compare the length of the string or paper to the list below to determine your ring size. If 
you are between sizes, order the larger size.
