How the WHR Calculator Works

1

Two measurements

Only waist and hip circumferences are needed. Use the same unit for both.

2

Simple division

Waist divided by hips. Unit cancels out, so cm and inches give the same WHR.

3

WHO category

Your WHR is matched to the WHO low/moderate/high category for your gender.

WHR Calculator FAQs

Is WHR better than BMI?
BMI uses height and weight; WHR uses fat distribution. Research suggests WHR can be a useful additional indicator, especially for central distribution.
Where exactly do I measure my waist?
At the narrowest point of your torso when relaxed — typically 1–2 inches above the navel.
Can WHR change with exercise?
Yes. Sustained cardio combined with strength work and dietary attention can reduce waist circumference and improve WHR over time.
Is this a medical diagnostic tool?
No. It is an informational tool based on published guidelines. For health concerns, consult a qualified professional.
Does WHR depend on the unit system?
No. The unit cancels in the division, so cm and inches give the same WHR.
What if my WHR is in the high range?
A high WHR may warrant a conversation with a doctor alongside other measures. It is not a diagnosis on its own.
