Here is a Ring Size Guide that shows the size and circumference of the ring in inches and mm.

When measuring finger size use a strip of paper ~1.4mm wide and wrap around desired finger, mark where it meets the edge. Then measure the length from the edge to the mark. This is the circumference of your finger, then compare it to this ring size chart.

**Remember when measuring your ring size, fingers swell in heat and shrink slightlyin cold so measure in neutral temperature and take into consideration the size of your knuckles.
