The standard height of a 3-year-old boy is 92-100cm and the standard weight is 14-15kg.
The formula for calculating the standard height of a 3-year-old child is age (years) x 7 + 75, which gives a result of 96cm. height growth will be affected by endocrine levels, genetic factors, and is also related to long-term nutrition and illness.
The formula for calculating the standard weight of a 3-year-old child is age (years) x 2 + 8, which gives a result of 14 kg. Weight is more affected by short-term nutrition and illness, and, therefore, fluctuates more.
If you consider that your child’s height and weight are significantly lower than the standardized values, there may be developmental delay, and you should bring your child to the hospital in time to confirm the diagnosis before treatment.
