# BMI Chart for Teenage Girl

## What is BMI?

It is not as simple as looking at an insurance height-weight chart to determine how much your teen should weigh. It entails taking into account the quantity of bone, muscle, and fat in his or her body. The amount of fat is the most important metric.

The body mass index is an excellent estimate of how much fat your kid has (BMI). Although it is not a precise metric, it provides a reasonably good estimate of how much of your teen’s body is made up of fat.

The following formulas are only for adults. The BMI of children and teenagers aged 2 to 19 years varies by age and gender. After calculating the BMI using one of the formulas below, an additional step is required. The BMI-for-age percentile is calculated by comparing your teen’s weight to the weights of other teens his or her age and gender.

In other words, by entering your child’s BMI into the CDC’s BMI-for-age development chart, you may establish if your child is underweight, normal, overweight, or obese. You may also quickly calculate it using the online calculator provided on the page.

## What is BMI and Why is it Important for teenagers?

Many of you undoubtedly already know what BMI is, but for those who don’t and want a thorough picture, let’s go over it briefly. Body Mass Index (BMI) is a measurement of a person’s weight in relation to their height. The most commonly used units are metric (meters for length/height and kilograms for weight). This is true even in imperial countries such as the United States.

Getting your BMI is as simple as dividing your weight by your height squared, as stated in the BMI formula:

BMI = weight/height²

As you can see, calculating your BMI isn’t rocket science, but for the lazy among us (believe us, you’re not alone), we’ve made it even easier with the BMI calculator for teens. The calculator is created exclusively for teens’ BMI and will provide you with additional information on how your BMI compares to this population group. If you want to calculate the BMI of someone who isn’t a teenager, we’ve created BMI calculators for all age groups.

## How to calculate Teenage Girl’s BMI using the English formula?

BMI(kg/m2) = mass(lb) / height2(in) × 703

For Example, a Girl who weighs 120 pounds and is 5 feet 1 inch tall has a BMI of 22.7.

Calculation= 120/(61)2 ×703= 22.7

## How to calculate Teenage Girl’s BMI using the metric formula?

A BMI between 25 to 29.9 is considered overweight. Anything over 30 is considered obese. Normal BMI is between 18.5 and 24.9. BMI cut-offs for people of South Asian descent are different. Below is the Chart:

BMI can be calculated using pounds and inches. BMI= Weight in Pounds x 703 (Height in Inches) x (Height in Inches)

•            Multiply your weight in pounds by 703.
•            Divide that answer by your height in inches.
•            Divide that answer by your height in inches again.

BMI can be calculated using kilograms and meters. BMI= Weight in Kilograms /(Height in Meters) x (Height in Meters)

•             Your weight in kilograms.
•             Divided by your height in meters.
•             Divide that answer by your height in meters again.

## Teens’ BMI prime and healthy BMI

BMI Prime is a new feature in the BMI calculator for teens that we haven’t highlighted before. This number, obtained from BMI, indicates how close your BMI is to the “healthy BMI for adults.” Adults with a healthy BMI should have a BMI of 25kg/m2. Although this is very useful for men and women, its validity for teens and children is doubtful at best, but we have decided to retain it here for comparison purposes and consistency.

To calculate your BMI prime, simply divide your actual BMI by 25, and you should get a value near to 1. The closer your BMI is near one, the healthier it is thought to be. However, because we’re dealing with smaller numbers, the difference between worryingly ill and ‘ideal’ is significantly smaller than with traditional BMI assessments.

We’ve already mentioned that the BMI prime is largely useless for most youngsters. This is due to the wide range of what constitutes a healthy BMI among different ages. A healthy BMI for teenagers is between 14 and 25, depending on age and gender. We’ll look at why this happens in the following section.

## The importance of a BMI chart for teenagers

BMI charts truly govern when it comes to defining what a healthy BMI for teens is. That is, BMI charts for teenagers are the medical approach to identify whether a youngster has a healthy body mass index or whether they are at risk. These charts (shown below) differ for boys and girls and provide a visual representation of the percentiles discussed in the preceding section.

Looking at the charts, you may easily determine what percentile you fall into and, as a result, how (un)healthy your BMI is. Many factors influence the body’s composition and proportions during this early stage of development, both of which affect the BMI value.

If numerous elements are overlooked in an adult’s BMI, it is considerably worse for teens and children. One solution is to split the permitted BMI values by age and gender and just compare a certain teenager to the rest of the teenagers his or her age. This is far from ideal, but when combined with WHO’s broad margins for healthy BMI for teens, it results in a rather robust diagnostic approach.
