The normal range of height for a three-year-old child is usually between 93-98cm for girls and 94-99cm for boys. Typically, a child’s height is related to factors such as genetics, diet, exercise and illness. Children of the same age and race may develop faster or slower in a similar environment, so there are individual differences in height. However, the normal height for a three-year-old girl is about 93-98cm and for a boy is about 94-99cm. Although the height of three-year-old children individual differences, but if the child’s height is significantly different from children of the same age, or for a period of time the child’s height does not show signs of growth, then you need to go to the hospital as soon as possible to find out the cause of the disease, to rule out the possibility of disease, and early intervention to ensure that the child’s height development will not be affected.
