## BMI Calculator for Children and Teens

Body mass index (BMI) is one way to estimate a person’s body fat that takes into consideration the person’s height. BMI is calculated using a person’s weight and height. In children and teens, BMI is used to find out if a child or teen is underweight, of a healthy weight, overweight, or obese. A child’s body fat changes with age. Also, girls and boys differ in their amount of body fat as they mature. This is why BMI for children, also known as BMI-for-age, includes gender and age.

This calculator gives an approximate BMI for children from ages 5 to 18. It will tell you if a child is underweight, at an ideal weight, at risk of being overweight, or is now overweight.

### What is BMI and does it matter for teens?

Many of you probably already know what BMI is, but for those who don’t and to have a complete picture, let’s talk briefly about its definition. BMI stands for Body Mass Index and it is a measurement of a persons weight in relation to their height. The most widely used units are those in metric (that is meters for length/height and kilograms for weight). This is true even in imperial countries like the USA.

Obtaining your BMI is very simple and can be done by simply diving your weight by your height squared, as shown in the BMI formula:

BMI = weight/height²

As you can see it is not rocket science to calculate your BMI, but for those lazy amongst us (trust us, you’re not alone) we have made this task even simpler with the BMI calculator for teens.
