There is no absolute standard for height and weight, but the average 6 year old boy is about 117cm tall and weighs about 20kg. Under normal circumstances, the height of a 6-year-old boy is about 117cm and his weight is about 20kg. However, because height and weight are affected by genetic factors and nutritional status, there is no absolute standard. Some may be slightly above the standard, some may be slightly below it, but most are normal if they meet the standard in all other aspects and are in good spirits. It should be noted that, if the boy’s height and weight are significantly different from children of the same age, it is recommended to go to the hospital in time to check, to clarify the cause, early detection, early treatment, so as to avoid delaying the condition.
