How to Use This Calculator
You'll need a flexible tape measure and a few minutes. First, measure your waist at the narrowest point, usually just above your belly button. Stand up straight, breathe normally, and measure at the end of a gentle exhale. For hip measurement, wrap the tape around the widest part of your buttocks. Make sure the tape is level and snug but not compressing the skin. Let's use an example. A woman with a waist of 78 cm and hips of 102 cm would enter those values and select "Female." Her WHR is 78 divided by 102, which equals 0.76. The calculator shows this as low risk, pear-shaped body type. For a man with a waist of 94 cm and hips of 100 cm, his WHR would be 0.94, putting him in the high-risk apple-shaped category.

About Waist-to-Hip Ratio Calculator
The Waist-to-Hip Ratio (WHR) Calculator assesses your body fat distribution by comparing the circumference of your waist to your hips, providing insight into health risks associated with abdominal obesity. Research has shown that where you carry your body fat matters as much as how much you carry. People with apple-shaped bodies storing fat around their abdomen face higher risks of cardiovascular disease, type 2 diabetes, and metabolic syndrome compared to pear-shaped individuals who store fat around their hips and thighs. The World Health Organization defines elevated risk thresholds at 0.90 for men and 0.85 for women. The calculator determines your WHR value, identifies your body shape category, and provides your health risk classification based on these established guidelines. WHR is considered a better predictor of cardiovascular risk than BMI alone, as it directly captures central adiposity. This simple measurement requires only a flexible tape measure and can be tracked over time to monitor changes in body composition and health risk, making it a valuable tool for comprehensive health assessment.
When to Use This Calculator
WHR is particularly useful when you want to assess health risks that BMI might miss. Someone with a normal BMI of 22 could still have a high WHR if they carry most of their fat around the belly, which is sometimes called normal-weight obesity. This person would be at elevated risk for metabolic problems despite looking thin. Use this calculator during regular health check-ups, before and after starting a new fitness program, or if your doctor has mentioned concerns about abdominal fat. It's also helpful for tracking progress during weight loss, since belly fat is often the first to come off and the most dangerous to keep. Research shows that reducing your WHR by 0.05 to 0.10 can significantly lower your risk of heart disease and diabetes, even if your total weight doesn't change much.
How to Interpret Your Results
Your WHR result is a single decimal number. For the woman in our example with a WHR of 0.76, the calculator shows low risk, pear shape. In women, a WHR below 0.85 is considered low risk, while 0.85 and above indicates high risk. For the man with 0.94, high risk starts at 0.90. The body shape classification tells you whether you're apple-shaped (higher risk, fat stored around the abdomen) or pear-shaped (lower risk, fat stored around hips and thighs). Your WHR is also a better predictor of heart attack risk than BMI, according to a study of over 12,000 people published in the Lancet. If your WHR is in the high-risk category, don't panic. Lifestyle changes, particularly reducing processed foods and increasing physical activity, can significantly improve WHR. Aim to reduce your waist measurement by even 2 to 3 cm, which can meaningfully lower your ratio.
Tips for Better Results
Take your measurements at the same time of day, ideally in the morning before eating, for consistent tracking. Use a non-stretchy tape measure for the most accurate readings. If possible, have someone else measure you to get more consistent results. For women, hormonal fluctuations during the menstrual cycle can affect waist measurement by 1 to 2 cm due to bloating, so try to measure at the same point in your cycle. Remember that WHR is just one health indicator. Combine it with other measurements like blood pressure, blood sugar, and cholesterol for a complete picture. If your WHR is high, even modest weight loss of 5 to 10 percent of your body weight can significantly reduce abdominal fat and improve your ratio.
