BMI (Body Mass Index) Calculator
Understanding your Body Mass Index (BMI) is a great first step in assessing your overall health. BMI is a measure that uses your height and weight to work out if your weight is healthy. Our 3D BMI Calculator makes finding your number simple, fast, and visually intuitive.
Whether you use kilograms or pounds, our tool provides an instant calculation and a helpful visual gauge that shows where you fall on the health spectrum, from underweight to obese.
How to Calculate Your BMI
- Select Your Units: Choose between “Metric” (centimeters and kilograms) or “Imperial” (feet, inches, and pounds) units using the tabs at the top.
- Enter Your Details:
- For Metric: Enter your height in centimeters (cm) and your weight in kilograms (kg).
- For Imperial: Enter your height in feet (ft) and inches (in), and your weight in pounds (lbs).
- View Your Results Instantly: As you enter your details, your BMI score will be calculated and displayed in the central dial. The category (e.g., “Normal Weight”) and the visual gauge will also update in real-time.

Frequently Asked Questions (FAQ)
BMI is a good starting point for most adults, but it doesn’t tell the whole story. It doesn’t distinguish between fat and muscle mass (for example, athletes may have a high BMI due to muscle). For a complete picture of your health, it’s best to speak with a doctor.
This calculator is designed for adults. BMI in children and teens is calculated differently and compared against age- and sex-specific percentile charts.
