Use an inelastic string, wrap it around the root of the finger twice, mark it at the same position of the two loops of rope, straighten the rope, and the length between the two points is the circumference of the rope, then measure the size of the ring with the circumference of the ring against the ring ruler.

Pay attention to the measurement of ring size

1. When measuring the hand inch, please ensure that it can smoothly slide over the finger joints; If you feel too loose after wearing the ring, you can wrap a few circles of thin, red or silk thread around the inside of the ring. If it is too tight, you can apply moisturizing oil or soapy water on your fingers, so that you can put it on or take it off smoothly.

2, buy a ring in winter, because the weather is cold, the finger is one to a half sizes thinner than that in summer. If you want to get a more exact size, you can measure it at the end of the day, because the finger size is the largest at this time.

3. The dimension comparison table is for reference only. If you can't guarantee the accuracy of the measured figures, it is recommended to go to a jewelry store to measure your hands and avoid buying inappropriate rings.
