What is the standard height and weight for a one-year-old child?
Generally, the standard height range for a one-year-old boy is approximately 73.4-78.8 centimeters, and the standard weight range is 9.1-11.3 kilograms. For one-year-old girls, the standard height range is about 71.5-77.1 centimeters, and the weight range is 8.5-10.6 kilograms. A detailed analysis is as follows:
The standard height and weight for one-year-old boys and girls differ. Generally, the standard height range for a one-year-old boy is approximately 73.4-78.8 centimeters, with a weight range of 9.1-11.3 kilograms, while for girls the height range is approximately 71.5-77.1 centimeters, and the weight range is 8.5-10.6 kilograms. From a physiological development perspective, the first year after birth is an extremely rapid growth phase for infants, with rapid bone growth leading to significant increases in height. At one year old, infants also have high nutritional demands, and adequate nutrition is fundamental for weight gain. Insufficient nutrient intake may affect growth in both height and weight. Additionally, genetic factors also play an important role—children of taller and larger parents tend to be closer to the upper end of the height and weight ranges.
It is recommended to ensure adequate feeding and sufficient sun exposure in daily life to help promote the baby's growth in height.
