How to measure the length of fingers?

1. Wrap the silk thread around your finger first, then cut it off and straighten it, measure the length of the silk thread with a ruler, and then compare it with the table (for example, the length of the silk thread on your finger is 53MM, so your finger size is12);

2. Directly measure the inner diameter of the ring with a suitable ring, and determine the size according to the following dimensions (note that it is the inner diameter, excluding the thickness of the ring) (for example, if the measured inner diameter is 17MM, then your hand size is13);

If it is convenient, you can go directly to the jewelry store to measure your hands directly.

Extended data:

The hand is a part of the front end of the arm of a human or other primate. It consists of five fingers and palms, and is mainly used to hold things. Both hands are symmetrical and mirror images of each other.

Most people have a left hand and a right hand, except for deformity or hyperplasia at birth. Each hand has five fingers, including the index finger, middle finger, ring finger, little finger (also called tail finger) and only two thumbs, but it is also possible to have a sixth finger at birth. There are nails at the tips of the five fingers, each with its own length, which is longer than the palm end. The center of the palm is called palm print, and there are palm prints in the palm. Palmprint will deepen with time, so the palm print of the elderly will always be deeper than that of the newborn. There are fingerprints on the palm and fingers, but not on the back of the hand.
