Waist-to-Hip Ratio Calculator
Calculate your waist-to-hip ratio (WHR) to assess your risk for heart disease, type 2 diabetes, and other health conditions. Based on WHO guidelines.
Measure at the narrowest point above your belly button
Measure at the widest part of your hips/buttocks
How to Measure Correctly
Waist
- Stand upright and breathe out normally
- Find the midpoint between the lowest rib and the top of the hip bone
- Wrap a tape measure around this point, parallel to the floor
- Keep the tape snug but not compressing the skin
Hips
- Stand with feet together
- Find the widest part of your buttocks
- Wrap a tape measure around this point, parallel to the floor
- Make sure the tape is level all the way around
Frequently Asked Questions
What is waist-to-hip ratio (WHR)?
Waist-to-hip ratio is the ratio of your waist circumference to your hip circumference. It is calculated by dividing your waist measurement by your hip measurement. The WHO uses WHR as a measure of abdominal obesity and health risk.
How do I measure my waist and hips correctly?
Waist: Measure around the narrowest part of your torso, typically just above the belly button (at the midpoint between the lowest rib and the top of the hip bone). Hips: Measure around the widest part of your buttocks. Stand straight, breathe normally, and use a flexible tape measure snug but not tight.
What is a healthy waist-to-hip ratio?
According to the WHO, a healthy WHR is below 0.90 for men and below 0.80 for women. Ratios above these thresholds indicate abdominal obesity, which is associated with increased risk of cardiovascular disease, type 2 diabetes, and metabolic syndrome.
Why is WHR better than BMI in some cases?
WHR specifically measures fat distribution, particularly abdominal fat. BMI does not distinguish between fat and muscle or where fat is stored. Research shows that abdominal (visceral) fat is more dangerous than fat stored in the hips and thighs. People with a normal BMI can still have a high WHR and elevated health risks.
