What is BMI?

Body Mass Index (BMI) is a health assessment tool that uses your height and weight to determine if your weight falls within a healthy range. This scientifically-backed measurement helps identify potential weight-related health risks.

BMI Formula: BMI = weight (kg) / (height (m))²

Our BMI calculator follows World Health Organization (WHO) standards and provides instant, accurate results with personalized health recommendations.

BMI Categories

Under 18.5 Underweight
18.5 - 24.9 Normal
25.0 - 29.9 Overweight
30.0+ Obese

These WHO-standardized categories help identify health risks associated with weight. A healthy BMI range is typically 18.5-24.9 for most adults.
