Normal height and weight standard table for boys

There are three ways to compare the height and weight of boys:

A, it is generally believed that the standard weight of men is height (cm)-105= standard weight (kg).

B, the method of the World Health Organization to calculate the standard weight. Male: (height cm-80)*70%= standard weight. Standard weight plus or minus 10% is normal weight. Standard weight plus or minus 10%-20% indicates overweight or underweight. If the standard weight exceeds plus or minus 20%, it is obesity or underweight.

C, add standard weight calculation, standard weight = height (m)* height (m)*22, overweight calculation formula: overweight% = {(actual weight-ideal weight)/(ideal weight)} x 100%.
