Six years old, standard height and weight.

The standard value of a 6-year-old boy's height is 120cm and his weight is 2 1kg.

The growth rate of children is not fixed. If the annual height growth of a 6-year-old boy is less than 5cm, we can refer to a simple height and weight formula to judge whether the child's body value is normal.

The simplest formula to know the standard of height and weight is weight = own height-100= weight (kg).
