Fitness & Health

Calculate your waist-to-hip ratio (WHR) and instantly see your WHO cardiovascular risk level (low, moderate, high, very high), body shape (apple/pear/hourglass), and personalised health recommendations. Supports metric (cm) and US (inches) units.

Measure at the narrowest point (navel level)

Measure at the widest point of the hips

How to Use the Waist-to-Hip Ratio Calculator

  1. Choose metric or US units — select centimetres or inches using the toggle at the top of the calculator.
  2. Select your gender — men and women have different WHO risk thresholds, so gender is required for an accurate assessment.
  3. Measure your waist — stand upright and measure horizontally around the narrowest part of your torso, usually at or just above the navel. Take the measurement at the end of a normal exhale.
  4. Measure your hips — measure at the widest point of your hips and buttocks, keeping the tape horizontal.
  5. Click Calculate WHR — instantly see your WHR value, WHO risk level, body shape classification, health risk summary, and personalised recommendation.

📏 Measurement tip

Use a flexible cloth measuring tape. Do not suck in your stomach. Both measurements should be taken on bare skin or a single layer of thin clothing for consistency.

How the Waist-to-Hip Ratio Is Calculated

The formula is straightforward: divide your waist circumference by your hip circumference. Both measurements must be in the same unit.

WHR = Waist circumference ÷ Hip circumference

Your result is then compared against World Health Organisation (WHO) thresholds by gender:

Risk LevelMen (WHR)Women (WHR)
Low Risk< 0.90< 0.80
Moderate Risk0.90 – 0.950.80 – 0.84
High Risk0.96 – 0.990.85 – 0.89
Very High Risk≥ 1.00≥ 0.90

Worked Examples

Example 1 — Male, Waist 86 cm, Hips 98 cm

  1. 1.WHR = 86 ÷ 98 = 0.878
  2. 2.For men, WHR < 0.90 = Low Risk ✅
  3. 3.Body shape: Pear / Triangle
  4. 4.Interpretation: Body fat is distributed around the hips and thighs. Low cardiovascular risk.

Example 2 — Female, Waist 34 in, Hips 40 in

  1. 1.WHR = 34 ÷ 40 = 0.850
  2. 2.For women, 0.85 – 0.89 = High Risk ⚠️
  3. 3.Body shape: Apple / Inverted Triangle
  4. 4.Interpretation: Central fat accumulation is present. Higher cardiovascular and metabolic risk.

Example 3 — Male, Waist 102 cm, Hips 99 cm

  1. 1.WHR = 102 ÷ 99 = 1.030
  2. 2.For men, WHR ≥ 1.00 = Very High Risk 🔴
  3. 3.Body shape: Apple / Inverted Triangle
  4. 4.Interpretation: Significant abdominal fat. Medical evaluation strongly recommended.

Body Shape Classifications

🍐

Apple (Inverted Triangle)

Fat accumulates around the abdomen. Associated with higher visceral fat, elevated cardiovascular risk, insulin resistance, and metabolic syndrome. Common in men with WHR ≥ 0.90, women ≥ 0.85.

⌛

Hourglass (Balanced)

Waist and hips are proportionally balanced. A transitional distribution typically associated with moderate WHR values. Moderate risk depending on absolute circumference measurements.

🍍

Pear (Triangle)

Fat is stored primarily around the hips, thighs, and buttocks. The hips are noticeably wider than the waist. Associated with lower cardiovascular risk. Common in women with WHR < 0.80.

Why Waist-to-Hip Ratio Matters

The waist-to-hip ratio is one of the most reliable anthropometric measures of central (abdominal) obesity — and a stronger predictor of cardiovascular disease than BMI alone. While BMI measures total body weight relative to height, WHR specifically quantifies where fat is stored. Visceral fat (fat stored around the internal organs in the abdominal cavity) is metabolically active and releases inflammatory markers, free fatty acids, and hormones that raise risks for:

  • Cardiovascular disease (CVD) and coronary heart disease
  • Type 2 diabetes and insulin resistance
  • Hypertension (high blood pressure)
  • Metabolic syndrome
  • Non-alcoholic fatty liver disease (NAFLD)
  • Certain cancers (colorectal, endometrial, breast post-menopause)
  • Obstructive sleep apnoea

The World Health Organisation recommends using WHR alongside waist circumference and BMI for a complete picture of obesity-related health risk. A 2020 meta-analysis of over 400,000 participants found that every 0.10-unit increase in WHR was associated with a 7% increase in all-cause mortality in both sexes.

Frequently Asked Questions

What is a healthy waist-to-hip ratio?+

According to WHO guidelines, a healthy WHR is below 0.90 for men and below 0.80 for women. Values in this range are associated with the lowest cardiovascular and metabolic disease risk. The ideal WHR is typically 0.80–0.85 for women and 0.85–0.89 for men.

Is WHR better than BMI for assessing health risk?+

WHR and BMI each measure different things. BMI measures overall adiposity relative to height but cannot distinguish between fat and muscle or identify where fat is stored. WHR specifically measures abdominal fat distribution, which is a stronger predictor of cardiovascular events, type 2 diabetes, and metabolic syndrome. Using both together provides the best assessment.

Where exactly do I measure my waist and hips?+

Waist: measure horizontally at the narrowest point of your torso, usually 1–2 cm above the navel. Do not suck in your stomach; take the reading at the end of a normal breath. Hips: measure at the widest point around your buttocks and hips, keeping the tape parallel to the floor.

Can I reduce my WHR?+

Yes. Reducing WHR primarily involves losing visceral (abdominal) fat. This responds well to: regular aerobic exercise (150–300 min/week moderate intensity, or 75–150 min vigorous), resistance training (which builds lean mass and raises resting metabolic rate), caloric deficit with reduced refined carbohydrate and saturated fat intake, improved sleep (7–9 hours), and stress management (cortisol drives abdominal fat storage).

Does WHR change with age?+

Yes. Waist circumference tends to increase with age, particularly after 40 in men and after menopause in women, partly due to declining sex hormones that shift fat distribution from the hips and thighs toward the abdomen. Regular physical activity significantly attenuates this age-related shift.

Are the WHR thresholds the same for all ethnicities?+

The WHO general thresholds (< 0.90 male, < 0.80 female) are widely used, but some research suggests that South Asian, East Asian, and Middle Eastern populations may have elevated metabolic risk at lower WHR values. If you are of Asian descent, discuss population-specific thresholds with your healthcare provider.
