Step &; Nail 47; way

Wrap a wide piece of paper around the finger of the ring you are wearing.

There is a pen at the intersection, surrounded by a piece of paper.

After the paper strip is smoothed, the data obtained by grid measurement is the circumference of the ring to be purchased.

Check the number of rings according to the perimeter.

Matters needing attention

For your own accurate measurement, you can aim a wide strip of paper at the root of your finger at home, rub it for a whole circle at the root of your finger, and then mark the intersection surrounded by the wide strip of paper with a pen, measure the length of the strip of paper with a ruler, look for the corresponding ring number on the table, and adjust your number appropriately according to different seasons. Buy rings in winter. Because of the cold weather, your fingers are one and a half sizes thinner than those in summer. It is advisable to hold the ring and turn it around, and don't fall off easily. If you feel too loose after wearing the ring, you can wrap thin thread or silk thread around the inside of the ring several times. If it is too tight, you can apply soapy water to your fingers so that you can put it on or take it off smoothly.

Ring size measurement method:

? Wrap iron wire or cotton thread around the finger where you want to wear the ring. After ensuring the proper size of the circle, expand the circle into a straight line and measure its length to get the circumference of the required ring. Then compare it with the size chart above. There will be some errors in cotton thread measurement, and the iron wire measurement is basically accurate.

Tip:

When measuring, please do not measure directly along the finger root, but make a circle and adjust the size repeatedly to ensure that the finger can pass smoothly. Because knuckles are generally thicker than heels, the amount of light along the roots of fingers will be smaller.

How to simply measure the ring size

Measurement method 1

I already have the right ring to wear, but I don't know the exact number and size. Just take a suitable ring, measure the inner diameter of the ring, and determine the size according to the following dimensions (note that it is the inner diameter, excluding the outer ring of the ring). Attached drawings (the following method can be done with only one ruler, which is simple and accurate).

Measurement method 2

Find a thin thread (thin thread without elasticity) or a piece of paper and circle around the root of your finger to wear the ring.

Mark the overlapping parts of thin lines or strips with a pen.

Then measure its length with a ruler and compare it with the ring comparison table below to find the right size.

1. After putting on the ring filter, make sure it can smoothly slide over the knuckles.

2. If you want to get a more accurate size, you can measure it at night, because the finger size is the largest at this time, so it is recommended to take the average of many measurements.

3. Choose a rope that will not stretch or bend the measuring material.

4. Adjust your quantity according to different seasons. According to the principle of thermal expansion and cold contraction, buy a ring in winter. Because of the cold weather, you can take the ring and rotate it left and right, but it is not easy to fall off. It's one to half smaller than that in summer. It's better to feel a little tight after wearing it in summer.

If you feel too loose after wearing the ring, you can wrap a transparent fishing line on the inside of the ring to prevent it from falling off. If it is too tight, you can apply soapy water to your fingers so that you can put it on or take it off smoothly.
