Ring Finger Sizing

Our ring sizes are consistent with the sizes you find at your local jewelry store. It is best to measure your finger in the evening. Do not measure your finger when your hands are cold. To determine your ring size please:

1. Wrap a piece of string or a strip of 1/4 inch wide paper around your finger. Make sure it will go over knuckle.
2. Mark the point where the two ends meet.
3. Measure the string or paper against a ruler.
4. Compare your measurement to the chart below.

Ring Size	Length In	Length mm
6	2-1/16	51.5
6.5	2-1/8	52.8
7	2-3/16	54
