According to the Chinese Reference Standards for the Growth and Development of Children Under 7 Years of Age, the standard height for a 2.5-year-old girl is 88.4 to 95.9 cm and her weight is 11.7 to 14.6 kg.
Children have certain differences in height and weight due to genetic and nutritional differences. During the period from 2 years of age to puberty, height and weight prediction methods can be used to roughly estimate whether a child is in the normal range.
1. Height prediction formula = age × 7 + 75cm, 2.5 years of age length of about 90cm, at 90% to 110% of this value are normal.
2. Weight prediction formula = age × 2 + 8kg, 2.5 years old weight is about 13kg, at 90% to 110% of this value is normal.
Parents should always pay attention to the height and weight of their children in the course of their growth, and should consult a doctor in time if there is any phenomenon such as developmental delay.
