If the weight is within 10% of the standard weight, it is also regarded as normal weight. For example, a person's standard weight is 60kg by calculation, and if his actual weight is in the range of 54~66kg, it is considered as normal weight.
In international standards, if the body mass index is in the range of 18.5-24.9, it is considered normal. The reference value of Asia is 18.5-22.9, and that of China is 18.5-23.9, which is also the most suitable.
