BMI Calculator computes body mass index in metric (kg, cm) or imperial (lbs, ft/in) units. It displays the BMI value, category badge (Underweight, Normal, Overweight, Obese), your healthy weight range for your height, and a visual scale bar showing where your BMI falls.
BMI is a simple screening tool — it doesn't directly measure body fat or overall health, and doesn't account for muscle mass, age, sex, or ethnicity. Consult a healthcare professional for a proper assessment.
WHO standard ranges: below 18.5 = Underweight, 18.5–24.9 = Normal weight, 25–29.9 = Overweight, 30 and above = Obese.
It's the range of weights that would put you in the 'Normal weight' BMI category (18.5–24.9) at your current height.
BMI doesn't distinguish between muscle and fat mass. Muscular individuals can have a higher BMI while having low body fat, which is a known limitation of the metric.
Yes — enter height and weight in kg/cm or lbs/ft+in, and the calculator handles the conversion internally.
This calculator uses adult BMI categories. Children and teens require age- and sex-specific percentile charts, which this tool doesn't provide.
It displays your BMI value positioned along a color-coded bar spanning the Underweight, Normal, Overweight, and Obese ranges, giving a quick visual sense of where you fall.
