BMI Percentile

After calculating your kid’s BMI, you have to compare the results with the Children’s BMI Charts that are also available online. These charts help determine how the child’s BMI results compare with that of others of the same age and gender. As the BMI measurements start from age 2 or older, the child’s height, weight, and body fat are continuously changing, and that is why a kid’s BMI cannot be defined by an ugly number. Still, instead, it is described by percentiles. It categorizes into four groups of Healthy weight, underweight, overweight and obese.
Healthy:Children with their percentile ranging from 5th to 85th are considered to be healthy.
Underweight:Children below the 5th percentile is underweight and need proper diet and care because this can lead to many health problems.
Overweight:Kids or teenagers who are overweight, mostly have 85th percentile to 95th percentile.
Obese:Children with 95th percentile or higher are obese and require healthy changes in their diet plan and proper exercise.
These percentile charts or Children’s BMI Charts are for Children from the ages of 2 to 20 years old. Many parents get the impression that if their kid has a high BMI, he/she is overweight or has more body fat, this is not necessarily true. As the kids grow their body continuously changes, some children with high BMI may have more muscle, but less body fat and some with less height and weight may have more body fat but less BMI. For a better understanding of a Child’s BMI, you should consult with a pediatrician who is doing the routine checkups of your child.

BMI Calculation Formula:
