. According to modern aesthetics, the height of 163 should be lower than the normal biological weight, which will look better, but this is only a popular aesthetic among a few young people at present. The normal calculation method of biological weight is to take a girl's height minus 105 as her standard kilogram. Of course, it is normal for this kilogram to fluctuate by several kilograms. So if a girl is 163, the standard weight should be 163- 105 = 58kg. Then this normal weight standard, physical function will be better, physical quality will be better. Of course, the aesthetics of modern people tend to be thin in this figure, but in fact, from the perspective of healthy and long-term development, we should not pursue thinness excessively, and health is the best. Therefore, this figure is for your reference only. If some girls are thin, instead of pursuing them deliberately, then I suggest you strengthen nutrition and physical exercise to improve your physical fitness while keeping in shape.
