Simple and accurate health risk assessment
"Keep your waist circumference to less than half your height." This simple guideline (WHtR < 0.5) is an easy way to assess healthy weight.
Enter your measurements to calculate WHtR
May indicate insufficient body fat
Optimal range for most people
Increased health risk
Significantly increased health risk
Only requires two measurements: waist and height. Easy to remember the 0.5 rule.
More accurate than BMI for predicting cardiovascular risk and metabolic syndrome.
Same 0.5 cutoff works for men, women, and different ethnic groups.
Targets abdominal obesity, which is most harmful to health.
Effective for children, adults, and elderly populations.
Strong predictor of diabetes, heart disease, and mortality risk.
Lower risk of heart disease, stroke, and hypertension
Improved insulin sensitivity and blood sugar control
Significantly reduced risk of type 2 diabetes
Associated with longer life expectancy
Easier movement and reduced joint stress
More energy, better sleep, improved mood
Waist-to-height ratio (WHtR) is your waist circumference divided by your height, both measured in the same units. It's a simple indicator of abdominal obesity and health risk.
Research shows that keeping your waist circumference below half your height (WHtR < 0.5) is associated with significantly lower risk of cardiovascular disease, diabetes, and early mortality across populations.
WHtR focuses on abdominal fat distribution, while BMI only considers total weight. WHtR is often more accurate for predicting health risks because abdominal fat is most harmful. You can have normal BMI but unhealthy WHtR.
Yes, WHtR is effective across ages, genders, and ethnic groups. The 0.5 threshold applies universally, making it simpler than BMI which has different cutoffs for different populations.
Measure at the narrowest part of your torso, typically just above the belly button. Stand relaxed, breathe normally, and measure after exhaling. Keep the tape parallel to the floor.
Yes! Reduce waist circumference through cardiovascular exercise, strength training, healthy diet, stress management, and adequate sleep. Even small reductions significantly improve health.
Measure every 1-3 months when actively working on body composition. More frequent measurements may not show significant changes. Focus on long-term trends rather than day-to-day fluctuations.
WHtR is simpler and equally predictive of health risks. It only requires height (which doesn't change) and waist measurement, while waist-to-hip ratio requires measuring both waist and hips.
