How to Measure Ring Size

 

If you are measuring yourself, you can prepare a note or a rope, a pen, and a ruler. Rotate the rope or paper strip around the thickest position of the finger to measure, and tighten; then use the pen to make a mark on the same position of the two loops of the rope, take off the rope and straighten it, and measure the length between the two mark points with a ruler. This length is the circumference of the finger.

 

 

What should pay attention to when measuring the size of the ring?

1. Pay attention to the time of measuring the hand: the circumference of the finger will be different due to the influence of thermal expansion and contraction. It is best not to measure when it is too cold in the morning or evening, or when it is too hot at noon, the measured ring size may not be very accurate. In the winter, you can choose a slightly larger ring size; in the summer, you can choose a smaller ring size.

 

2. When measuring the size of the ring, measure the thickest part of the finger. Because when people wearing the ring, they will pass the knuckle. If the measurement is not the thickest part of the knuckle, the ring can not be worn.

 

3. Multiple measurements take the average: personal measurement will inevitably have errors, you can measure the ring size multiple times to ensure the accuracy of the data.

    The French method is based on the circumference of the inner ring of the birthstone ring. The calculation method is: the ring size = the inner circumference of the ring is - 40 (in millimeters); The American way takes the diameter of the inner ring (in millimeters).

     

    Therefore, the conversion of the American ring sizes is: Ring inner ring size (method) +40 = pi (3.1416) * the inner ring diameter of the custom name rings(US). For example, if you buy a ring with a size of 10.5, then the size of the US ring is (10.5+40)/3.1416≈16.
