Waist-to-Height Ratio Calculator

Calculate your waist-to-height ratio (WHtR) for accurate health risk assessment. More precise than BMI for evaluating visceral fat and metabolic health.

Waist-to-Height Ratio Calculator

Enter your waist circumference and height to calculate your WHtR and assess health risks

Measurement Units

Waist Circumference

Measure at the narrowest point, usually just above the navel

Height

Your standing height without shoes

Key Features

More accurate than BMI for health risk assessment

Universal 0.5 threshold for all ages and genders

Better predictor of visceral fat and metabolic health

Simple calculation with instant results

Personalized health recommendations

Understanding WHtR

Formula: Waist circumference ÷ Height

Healthy Range: Keep ratio below 0.5 (waist < half height)

Risk Assessment: Higher ratios indicate increased health risks

Advantage: Better than BMI for central obesity detection

Tips & Strategies

Measurement Tips: Measure waist at narrowest point, breathe normally

Reduce Ratio: Focus on core exercises and cardiovascular training

Diet Strategy: Reduce processed foods and increase fiber intake

Track Progress: Monitor weekly, same time of day for consistency

Pro Tips for Accurate Measurements

📏

Proper waist measurement: Use a flexible measuring tape at the narrowest point, typically just above the hip bones.

🚨

Avoid compression: Keep the tape snug but not tight - you should be able to breathe normally.

⏰

Consistent timing: Measure at the same time of day, preferably in the morning before eating.

📊

Why WHtR matters: Better predictor of health risks than BMI, especially for abdominal obesity assessment.

🏥

Medical consultation: High ratios indicate increased risk - consider discussing results with healthcare providers.

Frequently Asked Questions

What is a healthy waist-to-height ratio?

A healthy waist-to-height ratio should be below 0.5, meaning your waist circumference should be less than half your height. This applies to all ages and genders and is associated with lower health risks compared to higher ratios.

How is WHtR better than BMI?

WHtR is a better predictor of health risks because it specifically measures central obesity and visceral fat distribution. Unlike BMI, it doesn't require complex age and gender adjustments, and studies show it's more accurate for predicting cardiovascular disease risk.

How do I measure my waist correctly?

Measure your waist at the narrowest point, typically just above the navel. Use a flexible measuring tape, breathe normally, and ensure the tape is snug but not tight. Stand straight and don't suck in your stomach for accurate results.

What does a WHtR above 0.6 mean?

A WHtR above 0.6 indicates obesity and significantly increased health risks including cardiovascular disease, type 2 diabetes, and metabolic syndrome. This level requires immediate lifestyle changes and medical consultation.

Can children use the WHtR calculator?

Yes, one advantage of WHtR is that the 0.5 threshold applies across all age groups and genders. Unlike BMI, which requires age-specific charts for children, WHtR provides consistent health risk assessment for everyone.

How often should I check my WHtR?

Monitor your WHtR monthly or weekly if you're actively working to improve it. Measure at the same time of day for consistency, preferably in the morning before eating. Track changes over time rather than daily fluctuations.
