Enter your waist and hip measurements to instantly see your Waist to Hip Ratio (WHR) and a simple health risk category based on widely used WHO-style ranges.
Enter your measurements above to see your WHR and get a simple interpretation based on commonly used global thresholds.
This Waist to Hip Ratio (WHR) Calculator is simple to use and works globally with both centimeters and inches. Your data is calculated directly in your browser and is not stored on our servers.
Select male or female. The interpretation thresholds are slightly different for each group in most guidelines.
Measure your waist at roughly the narrowest point between ribs and hips, and your hips at their widest point. Use the same unit (cm or in) for both.
Click Calculate WHR to see your ratio and a basic category (low, moderate, or high risk) based on standard reference ranges.
Waist to Hip Ratio is a simple calculation that compares the size of your waist to the size of your hips. It is often used as an indicator of how fat is distributed around your body. Research suggests that people who carry more fat around the waist ("apple" shape) may have higher risk of certain health conditions than those who carry more around the hips ("pear" shape), even at similar body weights.
Our calculator uses commonly referenced World Health Organization-style cutoffs for adults:
These thresholds are general guidelines only. Different countries, medical organizations, and researchers may use slightly different boundaries, and WHR is just one small piece of the overall health picture.
No. Because WHR is a ratio (waist divided by hip), the units cancel out as long as you measure both in the same unit. You can use centimeters or inches according to your preference.
No. This calculator cannot diagnose or rule out any condition. It simply visualizes one widely discussed measurement. Always consult a qualified healthcare professional for medical questions.
