A, paper tape measurement

1. Preparation tools: cut a piece of paper tape, pen, scissors and ruler. Wrap the paper tape around the thickest part of the finger to be measured twice, pay attention to the thickest part of the finger joint, and tighten the paper tape, with comfort as the main factor;

2. Then mark the same position of the paper tape with a pen;

3. Straighten the paper tape and mark the distance between the two marks with a ruler.

Note: Although this measurement method is relatively simple, the error is relatively large. It is suggested to take the middle value for multiple measurements to reduce the error. In addition, the measuring season will also affect the results. If the recommended number of rings in winter measurement is more than half of the measured size, then the best measurement season is generally in the evening of spring and autumn, when the temperature is suitable and it is more suitable for measurement.

Second, the tool measurement

1, there is a special tool for measuring finger size, called ring size bar, which is a series of rings with different sizes and size bars engraved with numbers. The measurement method is to select the most suitable ring among the rings, and then put the ring in the ring size column to read the size of the finger.

2. After measuring the finger size, you can find the corresponding ring number according to the ring size comparison table. If the measured finger size is 52mm, the ring number is13; If the measured value is 58mm, the number of rings is 19.

Note: Different versions of the ring size table have different ring numbers, such as American version, Japanese version, Italian version, Chinese mainland version and Hong Kong version. Therefore, when choosing a ring brand, you must know which version of the ring size table is used by this brand in order to choose the right ring.
