Assess your health risks using the Waist-to-Hip Ratio (WHR) based on WHO guidelines. Simply enter your waist and hip circumference and gender to determine your health risk category and body shape classification.
See how WHR is calculated for different body types and what the results mean.
Measurements: Waist = 72 cm, Hip = 102 cm, Gender = Female
Calculation: WHR = 72 ÷ 102 = 0.71
Interpretation: For women, a WHR below 0.80 indicates low health risk. A ratio of 0.71 suggests a pear-shaped body (narrower waist, wider hips), which is associated with a lower risk of cardiovascular issues compared to abdominal fat distribution.
Measurements: Waist = 94 cm, Hip = 100 cm, Gender = Male
Calculation: WHR = 94 ÷ 100 = 0.94
Interpretation: For men, a WHR between 0.90 and 0.99 indicates moderate health risk. This value of 0.94 falls into the moderate risk zone, suggesting some abdominal fat accumulation. Body shape is balanced between apple and pear distribution. Lifestyle modifications such as diet and exercise may be beneficial.
Measurements: Waist = 110 cm, Hip = 98 cm, Gender = Male
Calculation: WHR = 110 ÷ 98 = 1.12
Interpretation: For men, a WHR of 1.0 or above indicates high health risk. A ratio of 1.12 suggests an apple-shaped body (wider waist, narrower hips), which is associated with increased visceral fat and higher risk of cardiovascular disease, type 2 diabetes, and metabolic syndrome. Medical consultation is recommended.
Waist-to-Hip Ratio (WHR) is calculated using a simple division:
Where:
Measurements must be in the same unit (both in cm or both in inches) for the ratio to be valid.
The World Health Organization (WHO) defines health risk categories based on WHR values, with different thresholds for men and women:
| Health Risk | Men | Women | Body Shape |
|---|---|---|---|
| 🟢 Low Risk | < 0.90 | < 0.80 | Pear Shape |
| 🟡 Moderate Risk | 0.90 - 0.99 | 0.80 - 0.89 | Balanced |
| 🔴 High Risk | ≥ 1.00 | ≥ 0.90 | Apple Shape |

Waist-to-Hip Ratio (WHR) is a simple yet powerful anthropometric measurement used to assess body fat distribution and associated health risks. It is calculated by dividing your waist circumference by your hip circumference. Unlike BMI (Body Mass Index), which only considers total body weight relative to height, WHR provides valuable insight into how fat is distributed throughout your body — specifically whether fat accumulates around your abdomen (central obesity) or around your hips and thighs.
The WHR is considered a reliable predictor of health risks because abdominal fat (visceral fat) is metabolically more active and dangerous than subcutaneous fat found in the hips and thighs. Visceral fat surrounds internal organs and is strongly linked to inflammation, insulin resistance, and cardiovascular disease. Research has shown that WHR may be a better predictor of heart attack risk than BMI alone, with some studies suggesting it can identify cardiovascular risk in individuals who would otherwise be classified as "normal weight" by BMI standards.
The World Health Organization (WHO) recommends maintaining a WHR below 0.85 for women and below 0.90 for men to minimize health risks. Values above these thresholds indicate central obesity and increased risk for metabolic and cardiovascular conditions. The WHR is also used to classify body shapes: "apple-shaped" (higher WHR, more abdominal fat) and "pear-shaped" (lower WHR, fat stored in hips and thighs), with apple-shaped individuals facing greater health risks.
A high WHR (≥0.90 for men, ≥0.85 for women) is associated with significantly increased risk of cardiovascular disease (CVD), including heart attack, stroke, and hypertension. Abdominal obesity promotes inflammation, increases blood pressure, and negatively affects cholesterol profiles by raising LDL ("bad") cholesterol and triglycerides while lowering HDL ("good") cholesterol. A landmark study published in the European Heart Journal found that WHR was a stronger predictor of CVD than BMI, particularly in older adults.
Central obesity, as measured by WHR, is a key component of metabolic syndrome — a cluster of conditions including high blood sugar, high blood pressure, abnormal cholesterol levels, and excess abdominal fat. Individuals with high WHR are at substantially greater risk for developing type 2 diabetes. Visceral fat cells release inflammatory cytokines and free fatty acids that interfere with insulin signaling, leading to insulin resistance. Studies indicate that WHR can predict diabetes risk even in individuals with a normal BMI.
Multiple large-scale epidemiological studies have demonstrated that high WHR is associated with increased all-cause mortality. A study of over 200,000 participants in the UK Biobank found that WHR was more strongly associated with mortality risk than BMI, particularly for cardiovascular-related deaths. The relationship follows a J-shaped curve — very low WHR values (below ~0.70 for women and ~0.80 for men) may also carry slightly elevated risks, though the evidence is less consistent.
Your WHR determines your body shape classification, which provides additional context about your fat distribution pattern:
