Measure a ring that fits you (or your intended recipient): Place a ring that fits you over the circle, making sure the inside of the ring lines up with the outside of the circle. If you are between sizes, order the larger size.

 

 

Measure your finger and compare to the scale:

    Find a piece of non-stretchy string about 6" long, and 1/4" wide.
    Wrap it snugly around the base of your finger.
    Using a pen, mark the point on the string or paper where it overlaps, forming a complete circle.
    Compare the length of the string or paper to the lines on the paper below to determine your ring size. If you are between sizes, order the larger size.
