Waist-to-Hip Ratio Calculator
Calculate your Waist-to-Hip Ratio (WHR) to discover your body shape and assess your metabolic health. Find out if your fat distribution puts you at risk for heart disease based on WHO guidelines.
Your Measurements
Required because men and women naturally store fat differently, leading to different WHO risk thresholds.
Measure at the narrowest point, just above the belly button.
Measure around the widest part of the buttocks.

What is the Waist-to-Hip Ratio Calculator?
The Waist-to-Hip Ratio (WHR) Calculator is a simple yet powerful health assessment tool used to evaluate body fat distribution and potential metabolic health risks. Unlike weight or BMI alone, WHR focuses on where fat is stored in the body, particularly around the abdomen, which is strongly linked to heart disease, type 2 diabetes, and cardiovascular risk.
The Waist-to-Hip Ratio (WHR) is a simple but powerful metric that compares the circumference of your waist to that of your hips. It is a direct indicator of abdominal obesity (visceral fat), which is metabolically active and highly dangerous compared to fat stored elsewhere on the body.
By entering your biological sex, waist circumference, and hip circumference, this calculator determines your WHR score, identifies your body shape (such as apple or pear), and provides a health risk classification (low, medium, or high risk) based on WHO guidelines.
World Health Organization (WHO) Cut-offs
The WHO defines abdominal obesity as:
- Men: A WHR above 0.90. (A ratio above 1.00 is considered High Risk).
- Women: A WHR above 0.85. (A ratio above 0.85 is considered High Risk, and > 0.80 is Moderate Risk).
The Danger of the "Apple" Shape
People with an "Apple" shape carry most of their excess weight around the belly. This type of fat (visceral fat) surrounds internal organs like the liver and pancreas, releasing inflammatory compounds and fatty acids directly into the bloodstream. This leads to insulin resistance, raising the risk of Type 2 Diabetes, hypertension, and cardiovascular events far more than having a "Pear" shape (fat stored in the hips/thighs).
How to Improve Your Ratio
You cannot spot-reduce fat, but you can lose visceral fat through overall weight loss. Visceral fat is usually the first to go when you enter a calorie deficit. A combination of high-intensity aerobic exercise, a diet low in added sugars (which heavily promote belly fat), and stress management (lowering cortisol) is the most effective strategy.
How it Works
The calculator measures the proportion between your waist and hip measurements to assess central obesity. Fat stored around the waist (visceral fat) is considered more harmful than fat stored around the hips and thighs.
- Step 1: Enter your biological sex (male or female).
- Step 2: Measure your waist circumference at the narrowest point.
- Step 3: Measure your hip circumference at the widest point.
The tool then compares your ratio against internationally recognized WHO risk thresholds to determine your health category and likely fat distribution pattern.
Formula (With Example)
Waist-to-Hip Ratio Formula:
WHR = Waist Circumference ÷ Hip Circumference
Example Calculation:
If a woman has a waist measurement of 75 cm and hip measurement of 95 cm:
WHR = 75 ÷ 95 = 0.79
According to WHO standards:
- Women: WHR above 0.85 may indicate higher health risk.
- Men: WHR above 0.90 may indicate higher health risk.
In this example, a WHR of 0.79 would generally fall into the low-risk category and may reflect a pear-shaped body type.

Frequently Asked Questions
Find clear answers to common questions about this converter, accuracy, usage, and real-world applications.
What does the Waist-to-Hip Ratio (WHR) actually indicate?
Waist-to-Hip Ratio (WHR) measures how body fat is distributed between your waist and hips. It helps identify whether you carry more fat around your abdomen (central obesity) or lower body. Higher abdominal fat is associated with increased risk of heart disease, metabolic syndrome, and type 2 diabetes.
How is WHR different from BMI?
BMI estimates body weight relative to height, but it does not show where fat is stored. WHR specifically evaluates fat distribution, especially around the waist. This makes WHR a more useful indicator of cardiovascular and metabolic risk in many cases.
What is considered a high-risk WHR value?
According to commonly used health guidelines, a WHR above 0.90 for men and 0.85 for women may indicate a higher risk of heart-related conditions. However, overall health, lifestyle, and medical history should also be considered when interpreting results.
How do I measure my waist and hips correctly?
Measure your waist circumference at the narrowest point of your torso, usually just above the belly button. Measure your hip circumference at the widest part of your hips and buttocks. Keep the measuring tape level and snug, but not tight, for accurate results.
What body shapes are identified by this calculator?
The calculator may classify results into general body shapes such as apple-shaped (more abdominal fat) or pear-shaped (more hip and thigh fat). Apple-shaped fat distribution is typically linked to higher metabolic health risks.
Can I lower my WHR score?
Yes. Reducing abdominal fat through regular exercise, strength training, balanced nutrition, and calorie control can help lower your waist measurement and improve your WHR. Consistent lifestyle changes are key to long-term improvements.
How often should I check my WHR?
Checking your WHR every 4–8 weeks during a weight management or fitness program is usually sufficient. Regular tracking helps monitor changes in fat distribution and assess improvements in metabolic health over time.
Why is Waist-to-Hip Ratio important?
WHR is a strong indicator of health because it measures where your fat is stored. Storing fat around the abdomen (visceral fat) is far more dangerous than storing fat around the hips and thighs (subcutaneous fat). High visceral fat wraps around your major organs and increases the risk of cardiovascular disease, diabetes, and stroke.
What is the difference between an Apple and a Pear body shape?
Apple Shape: More weight is carried around the waist and abdomen. This corresponds to a higher WHR and a higher risk of metabolic diseases.
Pear Shape: More weight is carried around the hips, thighs, and buttocks. This corresponds to a lower WHR and a lower risk of metabolic diseases.
Is WHR better than BMI?
Yes, in many ways. Body Mass Index (BMI) only looks at total weight vs height. It cannot tell the difference between muscle and fat, nor where the fat is located. WHR specifically targets abdominal obesity, making it a better predictor of heart attacks and mortality, especially in older adults.
How do I measure accurately?
Waist: Measure at the narrowest point of your torso, usually just above the belly button. Do not suck your stomach in. Breathe out naturally before reading the tape.
Hips: Measure around the widest part of your buttocks and hips. Ensure the tape is parallel to the floor.
