There is no strict numerical definition of how tall a girl should be. The definition of “beauty” is not standardized and unique, so it is recommended not to be overly obsessed and pressured.
A girl’s height is related to many factors, such as genetic factors, acquired nutrition, physical exercise, age and so on. There is no strict numerical regulation on how tall a girl should be, and the heights of women of different ages are different. Most adult women’s height is centered between 155cm and 175cm, but this is not the most standard definition of height.
Moreover, the evaluation of height needs to be combined with other factors, such as weight and body mass index. Most people do not need to achieve a perfect value, as long as they look harmonious, well-proportioned and healthy.
It is advisable to consult a medical professional for details.
