How much should an 8 year old boy and girl weigh?
When talking about the weight of an 8 year old child, you will often see a child’s weight chart at the doctor’s office, you need to know that the graph does not always show a healthy weight for an 8 year old child.
When a child is 8 years old, it is very difficult to determine what the average weight is, because nowadays genes also play a role in determining how much the average weight is. If parents are included in having a short body, then naturally their children are like that too and there are many other factors that play an important role in the weight of an 8 year old child.
The Average weight for eight-year-olds
The average weight of an 8-year-old girl is 58 pounds and that of a boy is 56 pounds. The actual weight of your children is not the only way to determine the correct weight of a child. But we need to calculate the body mass index. The way to calculate body mass index is to divide the child’s weight (in pounds) by the child’s height (in cm). Then the number you get must be divided by the height. The number you get is then multiplied by 703 to get the BMI. So, the final number you get is the percentage you get on a typical growth chart.
The Average Percentage for 8-year-olds
What is the average percentage for an 8 year old child. Of course, these percentages will not give a direct answer to the average weight of 8-year-old boys and girls. However, this percentage figure will give you an estimate of what an 8-year-old would consider a healthy weight.
According to BMI, children aged 8 years with a range between the 5th and 84th percentiles will have a weight that is appropriate for their age. If based on BMI, the child’s weight is below the 5th percentile, then this indicates that the child is underweight. Conversely, if the BMI indicates that the child is above the 85th to 94th percentile, then this indicates that the child is overweight or obese.
Screening for 8-year-olds
If the child is outside the estimated normal weight or is considered a healthy weight, then we cannot spontaneously say that the child is underweight (unhealthy) or overweight (unhealthy). Well, you need to remember that a child’s BMI is only a number that is used as a tool to assist in screening potential problems that are sometimes faced by children based on their weight. You can test additional tests to check their health, such as measuring their waist circumference, skin thickness, physical activity, and daily diet.
If you are concerned about your child’s current weight or have concerns about their growth, we recommend that you consult a pediatrician. You can guide the graph below as a starting point for determining the weight of a child aged 8 years and as a guide for your child’s height up to the age of 12 years.
