Waist to Hip Ratio Calculator
Find your waist-to-hip ratio.
A simple indicator of fat distribution and related health risk.
How the Math Works
The Waist to Hip Ratio (WHR) is calculated by dividing your waist circumference by your hip circumference. To use the formula, first measure your waist at its narrowest point (typically just above the navel) and your hips at their widest point (around the fullest part of your buttocks). The ratio is then determined by waist ÷ hip. For example, a waist of 30 inches and hips of 36 inches yields a WHR of 0.83. This dimensionless number helps assess body fat distribution and associated health risks.
Practical Applications
To apply this calculation, measure your waist and hip circumferences accurately using a soft tape measure. Stand upright with feet together and relax your abdomen for precise measurements. Input these values into the calculator to determine your WHR. A lower ratio (e.g., 0.7 for women, 0.9 for men) typically indicates a healthier fat distribution, while higher ratios may suggest increased health risks. Use the result to track changes over time or compare against clinical guidelines for personalized health insights.
Day-to-Day Use
This calculation is useful in daily life for monitoring health trends and making informed lifestyle choices. A high WHR may prompt adjustments in diet, exercise routines, or medical consultations to reduce risks of heart disease, diabetes, or hypertension. It’s also helpful for fitness goals, as users can track improvements in waist or hip size through targeted workouts. Additionally, WHR is often used in medical check-ups to assess cardiovascular risk, making it a simple yet powerful tool for proactive health management.
Worked example
32 / 40 = 0.80.
