Waist-to-Height Ratio (WHtR) Calculator

The waist-to-height ratio (WHtR) calculator measures the ratio of your waist circumference to your height. It helps assess body fat distribution and the risk for certain diseases, guiding lifestyle changes to improve health.

What is Waist-to-Height Ratio?

The waist-to-height ratio is a measure of abdominal obesity (visceral fat). It identifies people at higher risk for heart and metabolic problems, regardless of age.

Waist-to-Height Ratio Formula:

WHtR is calculated using the formula:

Waist-to-Height Ratio = Waist Circumference / Height

Why Is Waist-to-Height Ratio Important?

WHtR is an important indicator of abdominal obesity. Research shows that a WHtR of 0.5 or higher is associated with increased risks of heart disease, metabolic syndrome, diabetes, and stroke. It is often a better predictor of health risk than BMI alone.

WHtR > 0.5 – Higher risk of diabetes, heart disease, stroke, and reduced life expectancy
WHtR < 0.5 – Considered healthy for both men and women globally

Example Calculation

Calculate WHtR for a man with a waist circumference of 92 cm and height of 182 cm:

Waist circumference = 92 cm
Height = 182 cm

WHtR = Waist / Height = 92 / 182 = 0.51
