## BMI Calculator for Children

This is a free online calculator to calculate BMI of children/ adolescents aged 19 years or under. BMI-for-age is calculated in the same way as for adults, but the result is interpreted in terms of age- and sex-specific percentiles (Reference: WHO growth chart for boys/ girls). For adults, on the other hand, BMI values are independent of sex or age.

Height & weight values may be entered either in metric or imperial units.

If the child is less than 2 years, measure the length of the body lying down for height value.

The following table lists the nutritional status corresponding to the weight percentile of children using BMI-for-age calculation.

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 |

Obese | Equal to or greater than the 95th percentile |
