Frequently Asked Questions
What is BMI?
Body Mass Index (BMI) is a measurement of a person's leanness or corpulence based on their height and weight, and is intended to quantify tissue mass. It is widely used as a general indicator of whether a person has a healthy body weight for their height.
Is BMI accurate for everyone?
BMI is a general tool and doesn't account for muscle mass, bone density, or overall body composition. Athletes and individuals with high muscle mass may have a high BMI despite having low body fat.
What are the BMI categories?
Underweight: < 18.5, Normal weight: 18.5–24.9, Overweight: 25–29.9, Obese: 30 or greater.
How to Use the BMI Calculator
To find your Body Mass Index, first select your preferred measurement system: 'Metric' for kg/cm or 'Imperial' for lbs/inches.

You'll receive a clear BMI value along with your clinically recognized weight category (Underweight, Normal, Overweight, or Obese) displayed in a high-contrast result card.
