1, paper (string) measurement method

You need to prepare three things: an A4 piece of paper, a pen and a scale. First, cut the extended edge of A4 paper into long strips with a width less than 1cm, and then wrap the strips around your fingers twice. Remember to wrap the finger joints with the largest point of the paper, and the tightness is mainly comfortable. Mark the overlapping position with a pen. Finally, put the paper flat and measure the distance between two points with a scale, which is the finger circumference. If a string is used, it is the same as a paper note, but it should be noted that the string should be as elastic as possible.

2, professional tool measurement method

There is a ring ruler specially used for measuring hand inches. This tool has a series of rings of different sizes. Put the appropriate ring on the finger to be measured, then take it off and put it on the ring stick, and compare the values. This kind of ring-sized stick is more common in jewelry stores.

3, ring diameter measurement method

If you have worn a ring before, you can print the inner diameter on paper, measure it with a scale and compare it with the size table. It should be noted that the pen should be perpendicular to the paper, and try to choose a pen without edges and corners, otherwise it is easy to make mistakes. Another more convenient way is to buy a stick the size of a ring, put the previous ring on it and write down the scale.
