Don’t measure when your body temperature is either too cold or too hot. A cold finger shrinks while a hot finger expands causing an inaccurate reading. Only measure when fingers are at room temperature.

Helpful Hints
Temperature is important
When two sizes seem to fit
If you hesitate between two sizes, always go with the larger one.
A wider band needs a bigger size
Extra wide band styles tend to run slightly small. If your ring has a narrower band than the one you wish to purchase, you may wish to order a ring a size larger than the size you normally wear.
Don’t use strings
When measuring your finger, always refrain from using a string; they tend to stretch, which can result in wrong size. ALWAYS use a paper strip about 1/2 inch width.
Big knuckles can affect your size
If your knuckle is a lot larger than the base of your finger and you’re using a paper strip, measure both the base of your finger and your knuckle and select a size in between the two.
