This is related to their own genetic factors.

Even if your genetic factors are not good, you will not grow tall.

But you can increase your muscles by exercising.

I think the standard is not much fat, and muscles must be there.

1. Calculation method 1:

Body mass index = square kilogram of body weight/square meter (kilogram)/height (meter)

Formula writing: body mass index = weight/(height) 2

Normal weight: body mass index = 18-25 (China's physical fitness standard is 18-22 for women and 20-24 for men).

Overweight: body mass index = 25-30.

Mild obesity: body mass index >; 30

Moderate obesity: body mass index >; 35

Severe obesity: body mass index >; 40

2. Calculation method 2:

Standard weight = height (m) × height (m) × standard coefficient (female 20, male 22)

Standard weight plus or minus 10% is normal weight.

Standard weight plus or minus 10 ~ 20% overweight or underweight.

Obesity or underweight is defined as plus or minus 20% of standard weight.

3. Calculation method 3:

Standard weight (kg) = height (cm)-105

For example, a man with a height of 170cm should weigh170 (cm)-105 = 65 (kg). Those who exceed the standard weight 10% are overweight, and those who exceed 20% are obese; Under 0/0% of standard weight/kloc, those below 20% are thin.

Note: The above calculation method is only applicable to adults. Not suitable for children, old people or people who are too short.
