You divide the whole height by the height from the sole of your foot to your navel. If the score is close to 0.6 18, then the body proportion is called the golden section, which is the best proportion. Your ratio is a little high. Your lower limbs are too long. No wonder you are so thin. 103: 158=0.652

This is in line with the current fashion of long legs, but it is limited by height. If you have 175, your leg is 1 meter. 158 is 88.

But your figure is really not the golden section. Of course, the lower body looks better.

You have to add some weight, so it looks like a piece of paper.
