Waist to Height Ratio Calculator

Calculate your waist-to-height ratio and health risk category.

WHtR = Waist Circumference / Height\n\nCategories:\n< 0.40: Underweight\n0.40-0.49: Healthy\n0.50-0.59: Overweight\n>= 0.60: Obese
Example:\nWaist: 32 inches\nHeight: 70 inches\n\nWHtR = 32 / 70 = 0.457\nCategory: Healthy\nRisk: Low\nTarget waist = 70 * 0.50 = 35 inches max

What is waist-to-height ratio?

WHtR is waist circumference divided by height. A simple screening tool for abdominal obesity and health risk.

What is a healthy ratio?

Below 0.50 is healthy for most adults. The guideline: "Keep your waist to less than half your height."

How do I measure my waist?

Measure at the narrowest point between ribs and hips, or at navel level. Measure in a relaxed state, not holding breath.

Is this better than BMI?

WHtR may better predict cardiovascular risk than BMI because it accounts for central obesity (abdominal fat).

Does age or gender matter?

The 0.50 threshold applies to most adults regardless of age or gender, making it a simple universal metric.
