What is WHR?
Waist to Hip Ratio Calculator — Waist Hip Ratio Free
The waist to hip ratio (WHR) is calculated by dividing your waist circumference by your hip circumference. It measures where your body stores fat — around the abdomen (higher risk) or the hips (lower risk). This free waist hip ratio calculator gives you your WHR, body shape classification and cardiovascular risk in seconds.
The WHO uses WHR as one of the primary measures of abdominal obesity — a stronger predictor of cardiovascular disease risk than BMI alone. The waist to height ratio calculator result (waist ÷ height) is also shown — a ratio above 0.5 indicates elevated metabolic risk regardless of BMI.
How to Measure for the Waist Hip Ratio Calculator
- Waist measurement: Measure at the navel level, or at the narrowest point of your torso. Stand relaxed — do not suck in or push out. Take the measurement at the end of a normal exhale.
- Hip measurement: Measure at the widest point of your hips and buttocks. This is typically 20–23 cm below the navel.
- Measure in the morning before eating for consistency. Use a soft tape measure.
- Divide waist by hip to get your waist hip ratio. This calculator does it instantly.
WHO Standards
Waist to Hip Ratio Women and Waist to Hip Ratio Men — WHO Thresholds
The WHO defines abdominal obesity using gender-specific WHR thresholds. A higher waist to hip ratio means more abdominal fat relative to hip fat — indicating higher cardiovascular risk.
| Category | Men (WHR) | Women (WHR) | Risk Level |
|---|---|---|---|
| Low Risk | Below 0.90 | Below 0.80 | Healthy — low cardiovascular risk |
| Moderate Risk | 0.90–0.99 | 0.80–0.85 | Moderate — monitor waist size |
| High Risk | 1.00 and above | 0.86 and above | High — elevated CVD & diabetes risk |
Body Shape Calculator — Apple vs Pear Body Shape
The body shape calculator classifies you as either apple-shaped (android) or pear-shaped (gynoid) based on your WHR. Apple vs pear body shape is more than aesthetic — it determines where your body stores fat and your associated health risk. Apple-shaped individuals carry more visceral fat around organs, directly elevating cardiovascular and metabolic risk. Pear-shaped individuals store fat subcutaneously around the hips — this fat type is metabolically less harmful.
India Context
Waist Measurement — Indian-Specific Abdominal Obesity Thresholds
Indians are genetically predisposed to abdominal obesity even at normal BMI. The Indian Council of Medical Research (ICMR) uses lower waist circumference thresholds than Western guidelines — 90cm for Indian men and 80cm for Indian women — to define abdominal obesity. This is also supported by WHO Expert Consultation research on Asian BMI cutoffs and further validated by studies on South Asian visceral fat risk (NIH/PubMed).
A healthy waist size for Indian men is below 90 cm — this is also the ideal waist size target. For Indian women, waist circumference women threshold is 80 cm. These are 10 cm lower than WHO Western thresholds because South Asians accumulate more visceral fat at smaller waist sizes, driving higher rates of Type 2 diabetes and cardiovascular disease at lower body fat levels than Caucasians.
The waist circumference calculator above uses these Indian-specific thresholds when evaluating your result. The hip to waist ratio (the inverse of WHR) is sometimes used in research — a higher hip-to-waist ratio is associated with lower cardiovascular risk. Think of the belly fat calculator function of this tool: your waist measurement, combined with your WHR, gives the clearest picture of abdominal fat accumulation and health risk.
- Abdominal obesity affects approximately 40% of urban Indian adults
- Indian men develop Type 2 diabetes at waist sizes that are considered normal in Western populations
- Reducing waist by 5–10 cm through diet and exercise reduces cardiovascular risk by 10–15%
- Resistance training + walking specifically targets visceral abdominal fat in Indians
Waist to Height Ratio
Waist to Height Ratio Calculator — A Better Fat Risk Predictor
How Waist to Height Ratio Compares to WHR
The waist to height ratio calculator divides your waist circumference by your height. Research suggests it may be a better predictor of metabolic risk than waist-to-hip ratio because it scales to body size — tall people naturally have larger waists without increased risk.
- Below 0.40: Underweight — waist very small relative to height
- 0.40–0.50: Healthy — optimal fat distribution
- 0.50–0.60: Overweight — increased metabolic risk
- Above 0.60: Obese — high cardiovascular and diabetes risk
The simple rule: "keep your waist to less than half your height." A 170 cm person should aim for a waist below 85 cm. This threshold is consistent across all ethnicities and body types, making it a useful complement to the waist hip ratio calculator.
