Waist to Hip Ratio Calculator

What is Waist-to-Hip Ratio (WHR)?

The Waist-to-Hip Ratio (WHR) is an established clinical and anthropometric measurement used to assess how fat is distributed across your body. It differentiates between abdominal/visceral adiposity (apple shape or android pattern) and lower-body peripheral adiposity (pear shape or gynoid pattern).

According to the World Health Organization (WHO), excess fat stored around the abdomen carries substantially higher risks for cardiovascular disease, type 2 diabetes, and hypertension than subcutaneous fat stored around the hips and thighs.

How to Calculate Waist-to-Hip Ratio

The calculation divides waist circumference by hip circumference measured in identical units:

$$\text{Waist-to-Hip Ratio (WHR)} = \frac{\text{Waist Circumference}}{\text{Hip Circumference}}$$

For example, a woman with a 72 cm waist and 96 cm hips has a WHR of $72 / 96 = 0.75$, representing a healthy pear/gynoid proportion with low metabolic risk.

WHO Health Risk Standards

Sex	Low Risk (Pear)	Moderate Risk	High Risk (Apple)
Women	< 0.80	0.80 - 0.85	> 0.85
Men	< 0.90	0.90 - 0.99	≥ 1.00

Measurement Guidelines

Waist: Measure at the narrowest point of the torso, typically midway between the lowest rib and top of the iliac crest (just above the navel).
Hips: Measure around the widest horizontal circumference of the buttocks.
Keep the measuring tape flat, parallel to the floor, and snug without compressing soft tissues.

Frequently Asked Questions

Why is WHR important alongside BMI?

BMI only indicates overall heaviness relative to height, but fat location matters greatly. Visceral fat in the abdomen releases inflammatory cytokines and free fatty acids directly into the portal circulation, making high WHR a potent independent predictor of heart disease even with normal BMI.

What causes an apple vs pear body shape?

Genetics, hormones (such as estrogen promoting gluteofemoral fat and cortisol/androgens promoting abdominal fat), age, and physical activity levels influence regional fat deposition patterns.

Can spot reduction decrease waist size specifically?

Spot reduction is a myth. Total body fat loss achieved through caloric deficit, progressive resistance training, and aerobic exercise will steadily decrease abdominal visceral fat and lower your WHR.
