How do I determine my ring size?

 
METHOD 1 : with a meter

To measure your finger, you can use a tape measure. Measure the circumference of your finger in mm. This measurement corresponds to the size of the ring.      

1 - Take a meter
2 - Make it go around the phalanx of the finger in question.
3 - Mark off with a mark the exact point where the two ends meet.
4 - Measure the area between the marks.
5 - This is the size of your finger.
Example: Your ring size measuring 4.7 centimeters. (or 47 millimeters). The size of your finger is 47.
