Assess your physical health metrics instantly with our interactive BMI calculator online. This free Body Mass Index test helps you check if you are within a healthy weight range relative to your height. Toggle between metric and imperial units to get a detailed WHO weight classification, risk analysis, and target suggestions.
BMI serves as a quick screening metric to evaluate whether a person falls into healthy parameters, identifying potential clinical risks early on.
Understand where your body weight lies on the international scale. Know if adjustments in diet or active hours would benefit your range.
We prioritize health data privacy. Heights and weights entered are computed directly inside your browser and never sent to our servers.
According to the World Health Organization (WHO), a BMI between 18.5 and 24.9 is considered normal or healthy. Values below 18.5 are underweight, while values above 25 are overweight.
BMI only computes height and weight ratio. It does not measure body fat percentage, bone density, or muscle mass. For example, professional athletes or bodybuilders often calculate as overweight due to muscle weight.
The formula in metric is: weight (kg) divided by height squared (m²). In imperial, the formula is: weight (lbs) divided by height squared (inches²) multiplied by 703.
