Know where your fat sits — not just how much
While BMI tells you about total weight relative to height, Waist-to-Hip Ratio tells you where your body stores fat. Central (abdominal) fat carries much higher metabolic and cardiovascular risk than fat stored around the hips and thighs. This tool gives you a WHO-referenced, instant, and honest read on your body fat distribution.
What Is Waist-to-Hip Ratio (WHR)?
Waist-to-Hip Ratio (WHR) is a simple measurement that divides your waist circumference by your hip circumference: WHR = Waist ÷ Hips. It is widely used by the World Health Organization (WHO) as a marker for abdominal obesity and associated health risks such as cardiovascular disease, type 2 diabetes, and metabolic syndrome.
Unlike BMI, WHR specifically captures central fat distribution — making it a powerful complement to BMI in understanding metabolic health risk.
How to Use This WHR Calculator
- Select your unit system: Metric (cm) or Imperial (inches).
- Select your biological sex: Required, as WHO thresholds differ between men and women.
- Enter your waist measurement: Measure at the narrowest point, just above the belly button while standing relaxed.
- Enter your hip measurement: Measure at the widest point around the buttocks, feet together.
- (Optional) Enter your age: Used to provide tailored context in recommendations.
- Read your results: WHR value, health risk level, body shape type, and personalized tips.
How WHR Is Calculated
The formula
WHR = Waist circumference ÷ Hip circumference
Both measurements must use the same unit (cm or inches — the ratio is unitless either way).
For example: Waist 82 cm ÷ Hips 96 cm = WHR of 0.85.
Risk classification (WHO)
Men: Low < 0.90 | Moderate 0.90–0.99 | High ≥ 1.00
Women: Low < 0.80 | Moderate 0.80–0.85 | High > 0.85
A higher WHR generally indicates more abdominal fat and greater health risk.
WHO WHR Risk Categories (Reference Table)
| Sex | Low Risk (WHR) | Moderate Risk (WHR) | High Risk (WHR) |
|---|---|---|---|
| Male | < 0.90 | 0.90 – 0.99 | ≥ 1.00 |
| Female | < 0.80 | 0.80 – 0.85 | > 0.85 |

Apple vs Pear Body Shape — What Does It Mean?
🍎 Apple Shape (High WHR)
People with an apple-shaped body tend to store fat around the abdomen and waist (central adiposity). This is associated with higher metabolic risk — including increased likelihood of cardiovascular disease, insulin resistance, and type 2 diabetes.
- WHR > 0.90 in men
- WHR > 0.85 in women
- Fat concentrated around the midsection
🍐 Pear Shape (Low WHR)
People with a pear-shaped body tend to store fat around the hips, thighs, and buttocks. This distribution is generally associated with lower metabolic risk compared to central (abdominal) fat storage.
- WHR < 0.90 in men
- WHR < 0.80 in women
- Fat concentrated in hips and lower body
It is important to understand that body shape is primarily determined by genetics and hormonal factors. While you cannot completely change your shape, you can reduce overall body fat through lifestyle changes, which will improve your WHR over time.
WHR vs BMI — Which Is Better?
Both WHR and BMI are screening tools, not diagnostic measures. They each offer different insights:
| Measure | What it captures | Best used for | Limitation |
|---|---|---|---|
| BMI | Total weight relative to height | Quick population-level screening | Doesn't distinguish fat distribution or muscle mass |
| WHR | Fat distribution (central vs peripheral) | Metabolic & cardiovascular risk | Doesn't reflect total body fat percentage |
Using both BMI and WHR together gives a more complete picture of health risk than either measure alone.
