BMI Calculator — Body Mass Index, Category & Healthy Range

Our BMI Calculator helps you quickly determine your Body Mass Index (BMI) using your height and weight. Understanding your BMI is a crucial first step in assessing your overall health and identifying potential risks, especially as global health guidelines for weight management continue to evolve in 2026. This tool provides your BMI category, a personalized healthy weight range, and an explanation of what these numbers mean for your well-being.

The Body Mass Index (BMI) is calculated using a straightforward formula: weight (in kilograms) divided by the square of height (in meters) (BMI = kg/m²). For those using imperial measurements, the formula is weight (in pounds) divided by the square of height (in inches), multiplied by 703 (BMI = (lbs / in²) * 703). This standardized metric provides a population-level assessment of weight relative to height, offering a quick indicator of potential health risks.

While BMI is a useful screening tool, it doesn't directly measure body fat or account for muscle mass, bone density, or body composition. Therefore, highly muscular individuals might have a high BMI without being overweight, and conversely, individuals with low muscle mass might have a 'healthy' BMI but an unhealthy body fat percentage. Always consult a healthcare professional for a comprehensive health assessment, as BMI is just one piece of the puzzle.
