How to Calculate Waist-to-Height Ratio (WHtR)
WHtR = waist circumference / height, both in the same unit. A waist of 80 cm and height of 170 cm gives 80 / 170 = 0.47. A commonly cited reference point is keeping WHtR below 0.5.

Frequently asked questions
What is a healthy WHtR?
A commonly cited reference is below 0.5, meaning waist circumference less than half of height. This is general information, not a diagnosis.
What is WHtR for 80 cm waist and 170 cm height?
0.47: 80 / 170 = 0.47, which is below the commonly cited 0.5 reference point.
How is WHtR different from BMI?
WHtR looks specifically at waist circumference relative to height, while BMI compares total weight to height squared without accounting for where weight is distributed.
