Based on the measurement of China curve figure of ordinary women and the effect of body-building exercise on human body shape, the calculation method of female standard measurements is summarized: bust = height ×0.535, waist = height ×0.365 and hip = height ×0.565. According to statistics, the girth is less than 5cm, indicating thinness; More than 5cm, indicating that the conclusion is fat.

Due to professional needs, there is a certain gap between the measurement standards of professional female models and the normal standards.

According to the characteristics of China people, the standard of measurements is generally chest 84cm, waist 6 1cm and hip 90cm.

Under normal circumstances, the normal waist circumference of girls is less than 80 cm, and that of women is more than 80 cm. If the waist circumference exceeds the standard, it is suggested to control the weight through scientific and healthy methods in time to avoid serious obesity.

Usually, the waist circumference of human body is measured at the level of 105 to 1cm on the navel, but for obese people, it is necessary to choose the thickest waist circumference to measure. Clinically, by measuring the waist circumference of girls and boys, it can often help to judge whether there is obesity. It should be noted that although the normal waist circumference of girls is less than 80cm, the smaller the waist circumference, the better.

Under normal circumstances, girls' waist circumference should be less than 80cm, and the ratio of waist circumference to height should not be greater than 0.5. In daily life, if you need to measure waist circumference, you should keep your feet shoulder-width stable, put a tape measure between the bottom of your ribs and the top of your hips, and relax your body to measure. At the same time, it is suggested that girls measure their waistlines several times, and the results can be averaged to reduce the measurement error.

A4 waist circumference:

A4 waistline is 59-65cm, because a4 waistline refers to the thinnest position on a plane as wide as a4 paper, but the waistline depends not only on the width of the front, but also on the distance between the abdomen and the back, so even A4 waistline may be different, but most of them are concentrated within 59-65cm.

The contrast method of a4 waist is to compare a4 abdomen one by one. Waist line, like a4 width, is popular a few years ago and is a common method to describe a person's waist.

Because the waist of a4 is equal to the width, the width of a4 paper is 2 1 cm. According to the girth, it should be a waist circumference of 65.94 cm, which is very cost-effective 1.98 ruler, which is the size of one foot nine. But everyone's waistline is not completely round or oval, so it is a4, but different people's waistlines are not exactly the same.
