BMI calculator

Your body mass index using WHO thresholds, with your healthy weight range. A useful marker — not a diagnosis.

BMI depends only on height and weight. It ignores age, sex and muscle mass — hence its limits.

BMI is a population marker, not a diagnosis. Muscle and fat aren't distinguished — combine it with waist circumference and professional advice.

BMI: a useful but rough marker

Body mass index places your weight relative to your height on a population scale defined by the WHO. It's a good starting point, but it doesn't tell the whole story — here's why.

1

It doesn't tell muscle from fat. A muscular person can show an "overweight" BMI without excess fat, while a "normal" BMI can hide high body fat. Waist circumference completes the picture.

2

It doesn't fit everyone. Standard thresholds don't apply as-is to children (growth charts are used), pregnant people, elite athletes or older adults.

3

What matters is the trend. A single number says little; following your weight and habits over time says a lot. That's exactly Volumeal's honest approach: a range and a trend, not a fake verdict.
