Waist-to-Hip Ratio Calculator
Calculate your waist-to-hip ratio according to clinical guidelines. Understand your cardiovascular risk based on body fat distribution.
Understanding Waist-to-Hip Ratio
Waist-to-hip ratio is calculated by dividing waist circumference by hip circumference:
According to clinical guidelines, risk categories differ by gender:
- Women - Low Risk: WHR < 0.85
- Women - High Risk: WHR ≥ 0.85
- Men - Low Risk: WHR < 0.90
- Men - High Risk: WHR ≥ 0.90
Calculate Your WHR
Measurement Guide
Waist: Measure at the narrowest point between the bottom of the rib cage and the top of the hip bone.
Hip: Measure at the widest point of the buttocks while standing straight.

WHR Analysis & Recommendations
Your WHR of 0.74 indicates Low Risk for cardiovascular disease.
- Maintain your healthy body fat distribution pattern
- Continue regular physical activity to prevent central obesity
- Follow a balanced diet rich in fruits and vegetables
- Monitor your waist circumference regularly
Understanding Waist-to-Hip Ratio
Waist-to-hip ratio (WHR) is a measurement that compares waist circumference to hip circumference. It's an indicator of body fat distribution and central obesity, which is strongly associated with cardiovascular risk.
According to clinical guidelines, WHR risk categories are gender-specific:
- Women - Low Risk: WHR < 0.85
- Women - High Risk: WHR ≥ 0.85
- Men - Low Risk: WHR < 0.90
- Men - High Risk: WHR ≥ 0.90
WHR is calculated as: WHR = Waist Circumference ÷ Hip Circumference
- Central obesity (apple-shaped) is more dangerous than peripheral obesity (pear-shaped)
- WHR is a better predictor of cardiovascular risk than BMI alone
- Measurements should be taken with minimal clothing for accuracy
- Take measurements at the same time of day for consistency
- WHR doesn't account for muscle mass distribution
Test Your Knowledge
According to clinical guidelines, what is the low-risk WHR threshold for women?
Correct Answer: b) <0.85
For women, a WHR below 0.85 indicates low risk for cardiovascular disease according to clinical guidelines.
WHR thresholds differ by gender due to natural differences in fat distribution patterns between men and women.
If a woman's waist circumference is 68 cm and hip circumference is 90 cm, what is her WHR?
WHR = Waist ÷ Hip = 68 ÷ 90 = 0.756 ≈ 0.76
Her WHR is 0.76, which falls in the low-risk category (<0.85).
WHR is calculated by dividing waist circumference by hip circumference: WHR = Waist ÷ Hip
A man has a waist circumference of 95 cm and hip circumference of 100 cm. What is his WHR category?
WHR = 95 ÷ 100 = 0.95. Since 0.95 ≥ 0.90, this man is in the high-risk category for cardiovascular disease.
This indicates central obesity which increases cardiovascular risk significantly.
For men, a WHR of 0.95 indicates high risk of cardiovascular disease and metabolic syndrome.
Where should waist circumference be measured for accurate WHR calculation?
Correct Answer: b) At the narrowest point between ribs and hips
Waist circumference should be measured at the natural waist, the narrowest point between the bottom of the rib cage and the top of the hip bone.
Measure waist at the narrowest point (natural waist) and hips at the widest point of the buttocks for accurate WHR calculation.
Why is central obesity (high WHR) more dangerous than peripheral obesity?
Correct Answer: c) It's associated with visceral fat and metabolic risk
Central obesity deposits fat around vital organs (visceral fat), which releases inflammatory substances and hormones that increase cardiovascular and metabolic risk.
- Women - Low Risk: <0.85
- Women - High Risk: ≥0.85
- Men - Low Risk: <0.90
- Men - High Risk: ≥0.90
- Measure both waist and hip at the same time of day
- Take measurements after exhaling normally
- Use a flexible tape measure without compressing the skin
- Repeat measurements to ensure accuracy
- Measuring waist at the wrong location
- Measuring hips incorrectly
- Applying inconsistent tension to the tape measure
- Not considering the gender-specific thresholds
Medical Q&A
Q: How does WHR compare to BMI as a predictor of health risk?
A: WHR is often superior to BMI for predicting health risks:
WHR Advantages:
- Fat distribution: Measures central obesity, which is more metabolically harmful
- Visceral fat: Correlates with visceral adipose tissue around organs
- Cardiovascular risk: Better predictor of heart disease and stroke
- Metabolic syndrome: More accurate indicator of metabolic dysfunction
Limitations of BMI:
- No distribution info: Doesn't distinguish between fat and muscle
- Central obesity: Misses dangerous apple-shaped body patterns
- Muscle mass: Can misclassify muscular individuals as overweight
- Visceral fat: Doesn't correlate with internal organ fat
For comprehensive risk assessment, both measures should be used together.
Q: Can WHR be improved through lifestyle changes?
A: Yes, WHR can be significantly improved through targeted interventions:
Dietary Changes:
- Reduce refined carbs: Limits insulin spikes that promote abdominal fat storage
- Increase fiber: Helps reduce visceral fat accumulation
- Healthy fats: Omega-3s can help redistribute fat away from abdomen
- Control portions: Creates caloric deficit to reduce overall fat
Exercise Interventions:
- Aerobic exercise: Reduces visceral fat effectively
- Resistance training: Builds lean muscle and increases metabolism
- Core strengthening: Improves posture and appearance
- HIIT workouts: Particularly effective for abdominal fat loss
With consistent effort, WHR can improve within 6-12 weeks of lifestyle changes.
