Based on CDC growth charts, this calculator calculates body mass index (BMI) and the matching BMI-for-age percentile for children and teenagers aged 2 to 19 years. The findings of this calculator may differ somewhat from BMI-for-age percentiles obtained by other tools due to probable rounding mistakes in age, weight, and height.
How is Teen BMI calculated?
A BMI percentile calculator can be used to estimate your weight and height.
- Measure your height and weight.
- BMI can be calculated by using the BMI Calculator for Children and Teenagers. Standard formulas are used to compute the BMI number.
What is a BMI percentile and how is it interpreted?
When determining a child’s or teen’s BMI, a percentile can be estimated using the graph or calculator provided below. When comparing a child’s BMI to that of other US children who took part in national surveys from 1963-65 to 1988-944, these percentiles are used. As a child grows, his or her weight and height fluctuate, as well as the relationship between the two. The BMI of a child should therefore be compared to the BMI of other children of the same gender and age group.
BMI Chart For Teen
Among the most regularly used growth charts in the United States, BMI-for-age percentile growth charts are the most widely utilized. Weight-for-age BMI categories and percentiles are provided in the following table based on expert committee recommendations.
|Weight Status Category||Percentile Range|
|Underweight||Less than the 5th percentile|
|Healthy Weight||5th percentile to less than the 85th percentile|
|Overweight||85th to less than the 95th percentile|
|Obesity||Equal to or greater than the 95th percentile|
Understanding your BMI
Being underweight may indicate that you aren’t eating enough or that you are sick. A doctor can help you if you are underweight.

If you’re overweight, the most effective strategy to reduce weight is to do both diet and exercise. You can use the BMI calculator to get an idea of how many calories you should be eating in order to reach a healthy weight.
For obese people, the best strategy to lose weight is to combine diet and exercise with medication, if necessary. Get help and advice from a doctor.
Do adults and children understand BMI in the same way?
Because BMI is determined using the same formula for children and teenagers, the results are interpreted in different ways. BMI levels for children and teens are stated compared to other children of the same sex and age because of variations in weight and height as well as their relationship to body fatness. The CDC growth charts, which are based on national survey data collected from 1963-65 to 1988-944, were used to produce these percentiles.
Having a BMI above the 95th percentile for children and teenagers of the same age and sex is considered obese. If a 10-year-old boy of average height (56 inches) and weight (102 pounds) had a BMI of 22.9 kg/m2, that would be his BMI. This would place the boy in the 95th percentile for BMI, and he would be considered to have obesity. To put it another way, the child’s BMI is higher than the average BMI of 95% of 10-year-old males in the reference population. In the case of adults, BMI is used as a weight status indicator that is independent of gender or age.
