Usually a normal six-year-old girl’s height is between 109 and 126 cm, with a median height of about 117.5 cm. If the child’s height is 110 cm, it is usually normal. Due to individual differences in each girl’s genetics, physical condition, nutritional supplements, etc., her growth will be different at each stage.The height standard for a six-year-old girl is between 109-126cm, therefore, a six-year-old girl’s height of 110cm is normal. However, it should be noted that the growth of girls’ height is not equal and should be evaluated on the basis of the individual child’s own changes, and the so-called “normal value” should not be taken as a “standard” for evaluation. If there is any abnormality, it is advisable to consult a doctor.
