1. Wrap the silk thread around your finger first, then cut and straighten it, measure the length of the silk thread with a ruler, and then find the corresponding ring (Hua) number on the comparison table. Don't wrap the thread too tightly because your knuckles are slightly bigger than the ring. If your size is between two sizes, please choose a larger size. The number of rings worn by most girls is (China) 10- 15, among which 12 and 13 are more; The number of rings worn by most boys is (China) 17-22, of which 18-20 is more.

2. If you already have a suitable ring to wear, but don't know the specific quantity and size, directly measure the inner diameter of the ring with a suitable ring to determine the size (note that it is the inner diameter, not including the thickness of the ring).

3. Note: (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) When buying a ring in winter, because of the cold weather, the finger is one to one-half smaller 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 size comparison table is for reference only. If you can't guarantee the accuracy of the measured figures, I suggest you go to the jewelry store to measure your hands so as not to buy an inappropriate ring. (4) According to the principle of thermal expansion and contraction, it is best to choose the size close to the finger in summer, and it is not easy to fall in winter.
