Youth BMI Calculator
hat is Youth BMI?
Body Mass Index (BMI) is a widely used measure that relates weight to height. For adults, BMI categories are straightforward, but for children and teenagers, BMI is interpreted differently because their bodies are still growing and developing.
- Youth BMI takes into account age, gender, height, and weight to provide a more accurate understanding of health status.
- It’s not a diagnostic tool but a screening method to identify potential health risks.
By using a youth-specific BMI calculator, parents and caregivers can get a clearer picture of whether a child’s weight is appropriate for their age and height.

Example of BMI Calculation
Let’s walk through an example.
- Age: 12 years
- Height: 150 cm
- Weight: 45 kg
Step 1: Convert height into meters
150 cm = 1.5 meters
Step 2: Apply the BMI formula
BMI = weight ÷ (height × height)
BMI = 45 ÷ (1.5 × 1.5)
BMI = 45 ÷ 2.25 = 20.0
Step 3: Interpret the result
According to the calculator:
- BMI = 20.0
- Category = Overweight
This example shows how the calculator instantly categorizes the result to make it easy to understand.
