Ring Size
If you don’t know your ring size, you’ll be glad to know that there are easy ways to accurately measure your ring size.
The string method:
1. Use a non-stretchy string or a strip of paper.2. Wrap it around the base of your finger, snugly but not too tight.
3. Mark the point where the string or paper strip overlaps to create a full circle.
4. Put the string or paper strip in a straight line.
5. Measure the distance between the two marks in mm. (milliliters)
6. This is your ring size on the “Metric – mm” scale.
The inner diameter method:
1. Use a ruler or a caliper to measure the inside diameter of a ring that has the size you want.
2. Be as precise as possible and try to measure to a 10th of a millimeter.
3. Multiply the diameter by 3.14. Example: 17.8 mm x 3.14 = 56 mm
4. Your Metric-mm ring size is 56
