What Is the Waist-to-Hip Ratio Calculator

Waist-to-hip ratio (WHR) measures the proportion between waist and hip circumference to estimate central fat distribution risk. This tool calculates WHR and classifies risk by male and female reference thresholds.

How to Use

1. Select a reference gender range (female or male).
2. Enter waist and hip values in centimeters.
3. Click "Calculate" or edit values to update results.
4. Review the risk label, threshold table, gauge position, and guidance text.

Risk Threshold Rules

• Female: low risk < 0.79, moderate risk 0.79-0.84, high risk >= 0.84.
• Male: low risk < 0.89, moderate risk 0.89-0.99, high risk >= 0.99.
• Formula: WHR = waist / hip.

Interpretation Tips

• WHR reflects central fat distribution. Higher values usually indicate higher abdominal fat risk.
• Retest every 4-6 weeks at a similar time of day to compare trends.
• Review WHR together with body fat, blood pressure, and activity level.
• Regular exercise, better sleep, and balanced nutrition can improve WHR over time.
• If waist size keeps increasing or WHR stays high, consider consulting a doctor or dietitian.

Use Cases

• Track body-shape changes during fitness or fat-loss phases.
• Keep periodic records for home health management.
• Compare outcomes before and after diet or training adjustments.

Notes

• Recheck at similar times with consistent measurement methods.
• Measure waist at the narrowest abdominal point and hip at the fullest point.
• Results are for reference and do not replace medical diagnosis.
