Waist circumference

Hip circumference

Use this Waist-to-Height Ratio Calculator to compare waist circumference with height. The live calculator also calculates waist-to-hip ratio when hip circumference is entered.

Calculation Method

Waist-to-height ratio (WHtR) = waist circumference ÷ height

Half-height waist reference = height ÷ 2

If hip circumference is entered:

Waist-to-hip ratio (WHR) = waist circumference ÷ hip circumference

Use the same measurement unit for both values in each ratio.

Example

For a waist of 80 cm and height of 170 cm:

WHtR = 80 ÷ 170 ≈ 0.47

The half-height reference is:

170 ÷ 2 = 85 cm

A waist of 80 cm is therefore below half of the person’s height.

Understanding the Result

0.40–0.49: healthy central-adiposity range
0.50–0.59: increased central adiposity
0.60 or higher: high central adiposity

Important Note

WHtR is a screening measure, not a diagnosis or direct measurement of body fat. Standard interpretation may be unsuitable during pregnancy, for children under 5, and in some medical or growth-related circumstances.
