WHtR Calculator (Waist-to-Height Ratio)

Waist-to-Height Ratio — waist circumference divided by height. It predicts cardiometabolic risk better than BMI alone.

Below 0.5 is considered optimal for most adults. The simple rule: "keep your waist less than half your height".

Measure at the narrowest point between your lower ribs and hip bone, or at navel level. Stand relaxed, breathe normally.

BMI uses weight and height; WHtR uses waist and height. WHtR better captures central obesity and visceral fat risk.

The formula is the same, but some studies suggest slightly different thresholds. Values above 0.5 are concerning for both.

Very high cardiovascular risk. Abdominal obesity at this level is associated with diabetes, hypertension and metabolic syndrome.

WHtR thresholds differ for children. This calculator is designed for adults.

Yes — some Asian populations have higher health risk at lower WHtR values. Consult country-specific guidelines.

Yes — regular aerobic exercise and a balanced diet help reduce waist circumference over time.

Yes — it normalises for height, making it comparable across individuals of different statures.
