How to determine your ring size (OPTION 1)

1. Cut a strip of paper. The paper should be no wider than 3/4" and at least 4" long.
2. Wrap the strip of paper around your finger.
3. Mark the point where the two ends meet. It should neither be too tight, nor slip off easily.
4. Measure the paper against a ruler to get the circumference of your finger. Measure from the beginning to the mark with a ruler or tape measure.
5. Look up your ring size using the chart below

Tips

1. Temperature is important: 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.
2. When two sizes seem to fit: If you hesitate between two sizes, always go with the larger one.
3. A wider band needs a bigger size: If you consider purchasing a wide band, move up a size from your measurement, for comfort’s sake.
4. 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" width.
5. Big knuckles can affect your size: If your knuckle is a lot larger than the base of your finger, and you're using the virtual ruler, measure both the base of your finger and your knuckle and select a size in between the two.
