Waist-to-Hip Ratio Calculator
The waist-to-hip ratio (WHR) shows how fat is distributed on your body. A higher ratio means more fat around the middle, which carries more health risk. Enter your waist and hip measurements to get your WHR and risk level.
The World Health Organization (WHO) defines substantially increased health risk as a waist-to-hip ratio of 0.90 or above for men and 0.85 or above for women. Lower ratios indicate gynoid (pear) fat distribution, while higher ratios indicate android (apple) abdominal fat storage.

How to use Waist-to-Hip Ratio Calculator
- 1Select your biological sex.
- 2Enter your waist circumference at the narrowest point or midway between ribs and hips.
- 3Enter your hip circumference at the widest point around your buttocks.
- 4Check your WHR score, WHO abdominal obesity status, and body shape classification.
Apple vs Pear fat distribution
Android (apple) fat distribution concentrates adipose tissue around the abdomen and visceral organs. This fat is metabolically active and releases inflammatory fatty acids directly into the portal vein.
Gynoid (pear) fat distribution deposits adipose tissue subcutaneously around the hips and thighs, presenting significantly lower cardiometabolic risk.
Frequently Asked Questions
What is a good waist-to-hip ratio?
WHO considers 0.90 or above for men and 0.85 or above for women to indicate substantially increased risk.
What is the ideal waist-to-hip ratio for women?
Below 0.85 is the health target; many studies use 0.80 or less as low risk.
Can I lower my WHR?
Yes. Losing overall body fat through a caloric deficit usually reduces waist circumference first.
