What are the three criteria for judging leg length, and what are the three criteria for judging leg

The three criteria for judging leg length are: wrist line over the crotch, knee over the shoulder, and starting from the hip line.

1. Wrist line over the crotch: The wrist line over the crotch is the easiest to measure, as long as you stand up straight and the arm naturally hangs down, see if your wrist line exceeds the crotch position, because the general leg length of the person has a longer arm, so the wrist line will exceed the crotch position. For example, Victoria's Secret Angel with very long legs.

Everyone, in the case that the hands are not close to the thighs, the wrist line is basically over the crotch, and the daily public wrist line is over the tiger's mouth, and the body proportion is good.

2. Hug your knees over your shoulders: sit on the ground with your knees bent, hold your legs with both hands, and try to get your body close to your thighs, if your knees exceed your shoulders at this time, it is a long leg, because there are many factors affecting this method, such as posture, hunchback, protruding belly, big breasts, and even the height of the shoes you wear will affect the measurement results, so sometimes there may be "moisture".

3. Start from the hip line: The model industry measures the leg length from the hip line, measuring the back of the neck bone (the most prominent part of the back of the neck when the chest is raised and the head is lowered), and the distance from the tail keel (a small bone in the middle of the buttocks that is relatively sharp) This is the length of the upper body, measuring the distance from the hip fold (the fold line between the back of the thigh and the buttocks when standing upright) to the ground (barefoot), this is the length of the lower body, and the length of the lower body is subtracted from the length of the upper body to get a value, which is the ratio of the upper and lower body.

Nowadays, people in society pay more and more attention to their external beauty, and they have more and more attention to their appearance, and many people think that people with long legs are very good-looking, so they want to know how to judge the length of their legs. In fact, leg length has its own criteria for judging, so let's introduce what the three criteria for judging leg length are.

The first criterion for judging leg length is to use a formula。If the difference between height and sitting height divided by sitting height multiplied by one hundred is greater, the longer the leg length;

The second criterion is that both knees are over the shouldersIf both knees can go over the shoulders, then it belongs to the leg length ranks;

The third criterion is the wrist line over the crotchIf the wrist line can be higher than the crotch, then it must be one of the ranks of leg lengths.

The three criteria for judging leg length are as follows:1. The ratio of the upper and lower bodies: with the navel as the boundary, the ratio of the upper and lower bodies should be 5:8, in line with the "** division"."Law.

2. Chest circumference: measured from the fullest part of the armpit along the top of the chest, which should be half of the height.

3. Waist circumference: Under normal circumstances, the thinnest part of the waist is measured and the waist circumference is 20 cm smaller than the chest circumference.

The three standard wrist lines to judge the length of the legs are over the crotch, the elbow line is over the waist, and the knees are over the shoulders.

There are three standard leg lengths: the wrist line over the crotch, the elbow line over the waist and the knee over the shoulder, under this standard, the big cousin is of course a veritable long leg.

The wrist line over the crotch means that in the case of the natural standing of the human body, the arm naturally droops, and the line that is flush at the wrist is more than the crotch, and the elbow line over the waist only needs to tilt the body slightly to make the illusion that the elbow line is over the waist to set off the leg length. Knee-hugging over the shoulder means holding your knees with your hands while sitting, and the height of the knees can be higher than the shoulders.

Measurement of leg length.

The measurement method of leg length does not allow you to measure from the heel to the navel, and the leg-to-body ratio is not judged by the ** ratio.

Modeling measures leg length generally from the hip line, measuring the distance from the nape of the neck (the most prominent part of the back of the neck when the chest is raised and the head is lowered) to the tail keel (a small bone in the middle of the buttocks), which is the length of the upper body.

Measure the distance from the hip crease (the fold between the back of the thigh and the buttocks when standing upright) to the ground (bare feet), this is the length of the lower body, and subtract the length of the upper body from the length of the lower body to get a value, which is the ratio of the upper and lower body.

The standard comparison table of leg length is as follows:

If the average person has long legs, it is very normal to account for 40% to 50% of the total height. More than 50% is a good body proportion, and the most coordinated body proportion is **proportion: 1, that is, the proportion of heels to the navel and above the navel is **ratio, but ordinary people can't reach it at all.

Therefore, the general leg length ratio is more than 50% of the total height, which is a very good leg length ratio. If this ratio is less than 40%, it is problematic to multi-prompt, and it may be that the proportion is not harmonious.

Leg length can be measured in the following ways:

1. When comparing the length of the lower limbs on both sides, this method can be adopted. First, find a longer bandage or thread, fix one end to the umbilicus or anterior superior iliac spine, and stretch the other end towards the medial malleolus of the ankle on this side, that is, the tip of the medial ankle joint. Once you have pressed here, measure the length between the two points.

After that, the two lower limbs are compared, and it can be determined whether there is any unequal length of the two lower limbs.

2. The method of measuring the absolute length of the lower limb can be adopted, and the patient is still required to find a longer bandage at this time, one point fixed at the greater trochanter, that is, the outermost and most prominent part of the hip joint, and the other point fixed at the tip of the medial malleolus. By pulling the bandage tight and measuring the length of the bandage, you can determine the absolute length of one leg of the lower limb.

There are ways to judge leg length: Sitting height measurement

PS: When measuring sitting height, the body must be straight, the thighs are parallel to the ground and at right angles to the calves, and to reflect the ratio of the upper and lower body (leg-to-body ratio), you can use the Marhalov torso leg length index as a standard.

Mahalanobis index = [(height - sitting height) sitting height] 100, the larger the index, the better the leg-to-body ratio.

People with real long legs, generally speaking, the perineal line is higher, and the arm is longer, often in the state of natural drooping of the arm, the wrist line can exceed the perineal line, and the wrist line like kaia is below the hip line, and there can be such an old and long distance, it is definitely a super long leg that can stand the test.

Sit with your knees bent, fold your legs with your hands, and try to keep your body as straight as possible close to the thighs.

How to tell if a person's legs are long-legged, and some people's body proportions are not exactly proportional to height, so what exactly is the standard for leg length?

01 In fact, long legs and short legs are calculated according to the proportion, among which the trunk leg length index is mainly used to reflect the proportional relationship between height and leg length, and its calculation formula is: (standing height - sitting height) sitting height * 100. The unit of height is calculated in cm, and it should be noted that sitting height refers to the distance from the top of your head to the plane you are sitting on when you sit upright.

If the index is above 100, it means that the person is super long legs, long legs, sub-long legs, middle legs, sub-short legs, short legs, if the index is less than 75, it is ultra-short legs.

02 In fact, the body proportion is not completely proportional to the height, but in general, taller women are more likely to have long legs, while short men are more likely to have short legs. According to survey statistics, among adults aged 22-25 in China, those who belong to the ultra-short leg type, the one who belongs to the short leg type, the one who belongs to the sub-short leg type, and the one who belongs to the middle leg type, that is to say, the leg length of most people belongs to the middle leg type, and the sub-long leg type accounts for the long leg type, and the one that belongs to the ultra-long leg type, that is to say, the leg length of very few people belongs to the super long leg type. It is worth noting that long legs and short legs are not calculated directly by looking at the absolute length, but according to the proportions of the body.
