Introduction
Your waist to hip ratio (WHR) is a simple body measurement that compares the size of your waist to the size of your hips. It helps you understand where your body stores fat. People who carry more fat around their waist have a higher risk for heart disease, diabetes, and other health problems. To find your ratio, you divide your waist measurement by your hip measurement. A healthy waist to hip ratio is usually 0.85 or lower for women and 0.90 or lower for men. Use this Waist to Hip Ratio Calculator to quickly find your number and see where you stand.
How to use our Waist to Hip Ratio Calculator
Enter your waist and hip measurements below to find out your waist to hip ratio. This number helps you understand how your body stores fat and whether you may be at risk for certain health problems.
Waist Circumference: Measure around the narrowest part of your waist, just above your belly button. Use a soft tape measure and keep it snug but not tight. Enter the number in inches or centimeters.
Hip Circumference: Measure around the widest part of your hips and buttocks. Stand with your feet together and wrap the tape measure around the fullest point. Enter the number in inches or centimeters.
What Is Waist to Hip Ratio?
Your waist to hip ratio (WHR) is a quick way to check how your body stores fat. You find it by dividing your waist measurement by your hip measurement. For example, if your waist is 80 cm and your hips are 100 cm, your WHR is 0.80. This single number tells doctors a lot about your health because where your body keeps fat matters just as much as how much fat you carry.
Why Waist to Hip Ratio Matters
Fat that builds up around your belly (sometimes called an "apple" body shape) is more dangerous than fat stored around your hips and thighs (a "pear" body shape). Belly fat wraps around vital organs like your liver, pancreas, and intestines. This type of fat, called visceral fat, releases chemicals that can raise blood pressure, increase blood sugar, and cause inflammation. Over time, these changes raise your risk for serious health problems, including:
- Heart disease and stroke
- Type 2 diabetes
- High cholesterol
- Certain types of cancer
That is why WHR is often considered a better predictor of health risk than body weight or even BMI alone. BMI cannot tell the difference between someone who carries fat around their waist versus their hips, but WHR can. Athletes and fitness enthusiasts may also want to check their Fat-Free Mass Index (FFMI) for a more detailed look at body composition beyond simple fat distribution.
How to Measure Your Waist and Hips Correctly
To get an accurate WHR, you need two measurements taken with a flexible measuring tape:
- Waist: Stand up straight and breathe out gently. Wrap the tape around your midsection at the narrowest point, which is usually just above your belly button and below your rib cage. Keep the tape snug but not tight.
- Hips: Wrap the tape around the widest part of your buttocks. Look in a mirror or ask someone to help make sure the tape is level all the way around.
Measure directly against your skin or over very thin clothing. Do not measure over thick layers like a sweater or jacket, as this will give you a false reading.
WHO Health Risk Categories
The World Health Organization (WHO) uses different cutoff numbers for men and women because male and female bodies naturally store fat in different places. Here is how the risk levels break down:
| Risk Level | Women | Men |
|---|---|---|
| Low risk | 0.80 or below | 0.90 or below |
| Moderate risk | 0.81 – 0.85 | 0.91 – 0.99 |
| High risk | 0.86 or above | 1.00 or above |
A WHR above 0.85 for women or 0.90 for men is the point at which the WHO says health risks start to increase significantly.
What to Do If Your WHR Is High
A high waist to hip ratio does not mean you are unhealthy right now, but it is a warning sign worth paying attention to. The good news is that belly fat responds well to lifestyle changes. Here are steps that can help lower your WHR over time:
- Move more: Aim for at least 150 minutes of moderate activity per week, such as brisk walking, cycling, or swimming. Strength training also helps reduce visceral fat. If you are a runner, a Running Pace Calculator can help you structure your cardio sessions, while swimmers can use our Swimming Pace Calculator to track workout intensity.
- Eat whole foods: Focus on vegetables, fruits, lean protein, and whole grains. Cut back on sugary drinks, processed snacks, and foods high in saturated fat.
- Get enough sleep: Poor sleep is linked to increased belly fat. Most adults need 7 to 9 hours per night.
- Manage stress: High stress raises cortisol levels, which encourages your body to store fat around the waist.
If you are following a strength training program and want to gauge your workout effort, an RPE Calculator can help you manage training intensity to stay consistent without overtraining.
Limitations of WHR
While WHR is a useful screening tool, it is not perfect. It does not account for your age, muscle mass, or overall body composition. A very muscular person could have a different WHR reading than expected. For those interested in understanding how muscle mass affects their physique, an FFMI Calculator provides a more detailed body composition assessment. WHR also works best as one piece of a bigger picture. For a complete understanding of your health, combine your WHR results with other measures like BMI, waist circumference alone, blood pressure, and blood sugar levels. You can also use tools like a Percentage Calculator to track changes in your measurements over time. Always talk to a doctor or healthcare professional if you are concerned about your results.
