BMI is a screening tool, not a diagnosis. It doesn't distinguish muscle from fat — athletes often test 'overweight' on BMI while being lean.

About this calc

Compute your BMI from weight and height. Works in metric (kg, cm) or imperial (lb, in). Also shows your healthy weight range.

FAQ

What is a healthy BMI?
The WHO classifies BMI 18.5–24.9 as normal. Under 18.5 is underweight; 25–29.9 is overweight; 30+ is obese.
Is BMI accurate for muscular people?
Not really. Muscle is denser than fat, so athletes and lifters often score 'overweight' despite being lean. Use BMI as a rough screening tool, not the only metric.
Does BMI differ for men and women?
The calculation is identical. Body composition differs, but BMI cutoffs apply the same way in adult men and women.
