If you want to measure the size of your finger, you can measure it with a string or calculate it according to the existing ring. The simplest method is to measure the ring by hand, which is accurate and convenient.

Sometimes it is fashionable and cheap to buy rings online, but because I don't know the size of my fingers, I either buy a big one or a small one. The customer service asked me to try it at the counter, but the behavior of trying it without buying it would be looked down upon by the counter lady. I'm really embarrassed to go.

You don't need to go to the counter to stare. These methods can measure the size of fingers by themselves.

1, measure the string, find a string or thin strip, wrap it around the root of the finger, loose but not tight, and have a suitable circumference, then mark the intersection point, take off the string and measure the length with a ruler. Measure several times and calculate the average. This string must be inelastic.

2. Measure with the ring you wear, find the most comfortable ring you wear, draw a circle along the inner ring, then draw the quartering point of the circle, measure the diameter with a ruler, and find the appropriate number according to the ring hand-inch comparison table.

3. Measure with a hand-inch measuring ring, which is the most accurate and simple way to measure the finger size. Which ring is most comfortable to choose? Usually, the hand-inch measuring ring is made of metal and plastic, which can be bought on a treasure at a low price.
