Waist to Hip Ratio Calculator
Calculate your waist-to-hip ratio (WHR) using WHO reference categories
Calculate with Waist to Hip Ratio Calculator
Measure at the narrowest point, usually at the navel
Measure at the widest point of the buttocks
Your Waist-to-Hip Ratio
Your waist-to-hip ratio indicates a healthy fat distribution pattern with lower risk of cardiovascular disease and metabolic conditions.
Your waist measurement is 15.0 cm smaller than your hip measurement, producing a WHR of 0.85. Repeat measurements on a separate day before using the trend for planning.
Risk Level (Male Scale)
WHO WHR Classification
| Health Risk | Men (WHR) | Women (WHR) |
|---|---|---|
| Low Risk | < 0.90 | < 0.80 |
| Moderate Risk | 0.90 - 0.99 | 0.80 - 0.85 |
| High Risk | ≥ 1.00 | > 0.85 |
Health Implications by Body Shape
- - Higher cardiovascular disease risk
- - Increased type 2 diabetes risk
- - Greater metabolic syndrome prevalence
- - Elevated inflammatory markers
- - Higher cortisol-related fat storage
- - Lower cardiovascular disease risk
- - Better insulin sensitivity
- - Reduced metabolic syndrome risk
- - More favorable lipid profiles
- - Subcutaneous fat is less metabolically active
How to Measure Correctly
Waist: Stand upright and breathe out normally. Wrap a measuring tape around your midsection at the narrowest point, typically at the level of your navel or just above the hip bones. The tape should be snug but not compressing the skin.
Hip: Stand with feet together. Measure at the widest point of your buttocks/hips, keeping the tape level and parallel to the floor.
Tips: Use a non-stretchable tape measure. Measure directly against skin or over thin clothing. Take measurements in the morning before eating for consistency. Repeat each measurement twice and use the average.
Assumptions
Use Waist to Hip Ratio Calculator for body-measurement context when you need transparent inputs, educational context, and a result you can review without treating it as medical advice.
Worked example
When To Use Waist to Hip Ratio Calculator
- Start with measurements, timing, activity, or intake inputs that match your real situation instead of rounded placeholder values.
- Review whether the estimate fits interpret ratio estimates alongside body size, trend, and broader health context before changing a routine or discussing it with a professional.
Sample Input And Output Checks
- Start with inputs collected consistently, especially measurements, dates, intensity, and unit choices.
- Review waist placement, hip measurement, posture, units, and repeat timing before trusting the output.
- Ratio tools are screening aids; symptoms, clinical risk factors, and professional guidance matter more than one result.

Waist-to-Hip Ratio Calculator: Understanding Body-Shape Distribution
The waist-to-hip ratio (WHR) is a simple anthropometric measurement used to describe body-shape distribution. Calculated by dividing waist circumference by hip circumference, WHR can help you compare whether more measurement sits around the abdomen or hips. This calculator applies common gender-specific threshold bands as an educational screening estimate. It does not diagnose cardiovascular, metabolic, or diabetes risk; use it alongside waist circumference, BMI, body composition, blood pressure, lab results, and clinician guidance when health risk matters.
Technical Details: WHR Formula, WHO Classification Thresholds, and Measurement Methodology
The waist-to-hip ratio formula is straightforward: WHR = Waist Circumference / Hip Circumference, where both measurements are taken in the same unit. For men, this page labels values below 0.90 as lower, 0.90-0.99 as moderate, and 1.00 or above as higher. For women, it labels values below 0.80 as lower, 0.80-0.85 as moderate, and above 0.85 as higher. Measurement technique is essential: measure the waist consistently, measure hips at the widest point, keep the tape level, and repeat the measurement before acting on a single result.
Clinical Use Cases: Cardiovascular Screening, Diabetes Risk, and Metabolic Syndrome Assessment
WHR is most useful as a repeatable measurement trend. Use it to compare monthly waist and hip changes, check whether a training or nutrition plan is changing body-shape distribution, and decide whether you need a more complete body-composition review. A single WHR value should not be treated as a diagnosis. If the result raises concern, compare it with waist size, blood pressure, labs, family history, and professional guidance.

WHR vs BMI, Body Fat Percentage, and DEXA: Choosing the Right Body Composition Metric
Understanding how WHR compares to other body composition metrics helps you select the most appropriate tools for your health monitoring goals. BMI (Body Mass Index) measures overall weight relative to height but cannot distinguish between muscle mass and fat mass, nor can it identify where fat is stored, leading to well-documented misclassification of muscular individuals as overweight and failure to identify metabolically unhealthy normal-weight individuals who carry excess visceral fat, a condition sometimes termed metabolically obese normal weight (MONW). Body fat percentage, estimated through methods such as skinfold calipers, bioelectrical impedance analysis, or the U.S. Navy circumference method available in our Body Fat Calculator, provides information about total adiposity but does not specifically indicate fat distribution patterns that drive cardiovascular and metabolic risk. Waist circumference measured alone, which WHO considers an independent risk factor when exceeding 102 cm (40 inches) for men or 88 cm (35 inches) for women, captures abdominal fat accumulation but does not account for body frame size the way WHR does by normalizing waist measurement against hip width. DEXA (dual-energy X-ray absorptiometry) scanning represents the clinical gold standard for body composition analysis, providing precise measurements of fat mass, lean mass, and bone mineral density with regional distribution data, but its cost of $75-200 per scan and requirement for specialized equipment limits its accessibility for routine monitoring.
For best measurement practices, take WHR measurements in the morning before eating, wear minimal clothing, use a non-stretchable tape measure, stand upright with feet together, breathe out normally before measuring the waist, and repeat each measurement twice using the average value for calculation. Key limitations of WHR include its inability to distinguish between subcutaneous and visceral abdominal fat without imaging, reduced accuracy in very lean or very obese individuals, and the fact that WHR can remain stable even as both waist and hip measurements increase proportionally during weight gain.
