How this Waist-to-Hip Ratio (WHR) calculator works
Select sex (male or female) and units (metric cm or imperial inches), then enter waist circumference and hip circumference. We compute WHR (waist ÷ hip), classify your body shape as apple, pear, or balanced, and map your result to WHO health risk levels (Low, Moderate, High, Very High).
Your report includes the WHR value, body shape label, WHO threshold comparison, visual risk scale, cardiovascular and metabolic risk interpretation, health considerations, contributing factors, and personalized recommendations. Export a PDF or share results for clinical visits. Men with WHR above 0.90 and women above 0.85 exceed WHO high-risk thresholds for cardiovascular and metabolic disease.
WHR adds hip-proportion context that waist-only measures miss. For follow-up, try our Waist-to-Height Ratio (WHtR), Visceral Fat Risk, or Cardiovascular Risk calculators.
Waist-to-Hip Ratio (WHR) Health Risk Calculator – Apple vs Pear Body Shape
Every day, millions search "waist to hip ratio calculator", "WHR calculator", or "apple pear body shape health risk"—looking for a simple way to understand whether their body fat distribution raises cardiovascular or metabolic concern. Unlike BMI, which only compares weight to height, waist-to-hip ratio (WHR) tells you where fat is stored—around the abdomen (apple / android shape) or around the hips and thighs (pear / gynoid shape). Research consistently links higher WHR to greater cardiovascular disease, type 2 diabetes, and metabolic syndrome risk in many populations. Our free Waist-to-Hip Ratio (WHR) Health Risk Calculator computes your ratio in metric (cm) or imperial (inches), classifies your body shape, maps your result to WHO health risk levels (Low, Moderate, High, Very High), provides a risk interpretation for cardiovascular and metabolic health, personalized recommendations, and PDF export.
The World Health Organization (WHO) identifies substantially increased health risk when WHR exceeds 0.90 in men and 0.85 in women. Pair results with our Waist-to-Height Ratio (WHtR) Calculator, Visceral Fat Risk Calculator, and Cardiovascular Risk Calculator for a fuller metabolic and heart-health picture.
What Is Waist-to-Hip Ratio?
Waist-to-hip ratio is waist circumference divided by hip circumference using the same unit (cm/cm or in/in). The result is unitless and describes body fat distribution—not total body fat. Central obesity—excess fat around the waist and internal organs—is a major driver of insulin resistance, unhealthy cholesterol, fatty liver, and cardiovascular disease. WHR compares waist size to hip size to quantify this pattern.
People with apple-shaped bodies (high WHR) tend to carry more visceral (organ) fat; pear-shaped bodies (lower WHR) store more subcutaneous fat below the waist—generally associated with lower cardiometabolic risk at similar body weight. WHR has been used in epidemiology for decades and remains cited in WHO guidance alongside waist circumference and BMI for assessing obesity-related health risk in adults.
1What You Enter
Required inputs
- Sex: Male or Female (Pill toggle—for WHO thresholds and body-shape bands)
- Unit system: metric (cm) or imperial (inches)
- Waist circumference (cm or in)
- Hip circumference (cm or in)
Measurement technique
- Waist: narrowest point between lower rib and iliac crest, or consistently at the navel—standing, after normal exhale, tape snug, parallel to floor

2Formula & WHO Thresholds
Waist-to-hip ratio (WHR)
WHR = waist circumference ÷ hip circumference
Same unit for both (cm ÷ cm or in ÷ in). Example: waist 90 cm, hip 100 cm → WHR = 90 ÷ 100 = 0.90.
WHO high-risk thresholds
- Men: WHR > 0.90 — substantially increased cardiovascular and metabolic risk
- Women: WHR > 0.85 — substantially increased cardiovascular and metabolic risk
These cutoffs come from WHO expert consultation on obesity (2008) and are widely cited in clinical and public-health literature for adult screening.
Our graduated risk bands
| Level | Men | Women |
|---|---|---|
| Low | < 0.85 | < 0.75 |
| Moderate | 0.85 – 0.89 | 0.75 – 0.84 |
| High (WHO) | 0.90 – 0.94 | 0.85 – 0.89 |
| Very High | ≥ 0.95 | ≥ 0.90 |
Body shape classification
- Apple: WHR above WHO high-risk threshold — central (android) fat dominant
- Pear: WHR below pear cutoff — peripheral (gynoid) fat dominant (men < 0.85, women < 0.75)
- Balanced: intermediate distribution between apple and pear

Apple vs Pear Body Shape – Why It Matters
Fat distribution is not just cosmetic—it reflects different metabolic profiles. Visceral (intra-abdominal) fat is hormonally active, releasing free fatty acids and inflammatory cytokines that impair insulin signaling and raise cardiovascular risk. Subcutaneous hip and thigh fat may be comparatively less harmful in population studies, though total adiposity still matters.
| Shape | Fat pattern | Typical WHR | Health associations |
|---|---|---|---|
| 🍎 Apple | Central / abdominal (android) | Men > 0.90; Women > 0.85 | Higher rates of diabetes, hypertension, dyslipidemia, CVD in many cohorts |
| 🍐 Pear | Hips & thighs (gynoid) | Men < 0.85; Women < 0.75 | Generally lower cardiometabolic risk at similar BMI; still monitor overall health |
| ⚖️ Balanced | Intermediate | Between pear and apple cutoffs | Moderate risk—watch WHR trend over time; lifestyle can shift distribution |
Android vs Gynoid Fat Distribution
Clinicians and researchers use anatomical terms that map directly to apple and pear shapes:
Android (apple) distribution
- Fat accumulates around abdomen, chest, and upper body
- Higher proportion of visceral fat surrounding organs
- More common in men; rises in women after menopause
- Associated with insulin resistance, elevated triglycerides, low HDL
- Often responsive to waist-focused lifestyle change
Gynoid (pear) distribution
- Fat accumulates around hips, buttocks, and thighs
- Predominantly subcutaneous rather than visceral
- More common in premenopausal women
- Lower average cardiometabolic risk than android pattern at same BMI
- Still warrants attention if total weight or waist is elevated
Health Risks Associated with Elevated WHR
Higher WHR is associated with greater cardiometabolic burden in epidemiological studies. Individual risk still depends on genetics, fitness, diet, sleep, smoking, and laboratory results.
| Risk level | WHR pattern | Common associations |
|---|---|---|
| Low | Below moderate range | Lower average central-fat-related cardiovascular and diabetes risk |
| Moderate | Approaching WHO cutoff | Borderline pattern—lifestyle optimization often sufficient; watch waist trend |
| High | Above WHO threshold | Elevated metabolic syndrome, hypertension, prediabetes, and CVD risk in many groups |
| Very High | Well above WHO threshold | Strong screening signal for excess visceral fat; medical evaluation often advised |
WHR vs BMI vs WHtR – When to Use Each
| Measure | Formula | Best for | Limitation |
|---|---|---|---|
| BMI | Weight ÷ height² | Population weight screening | Misses fat distribution; muscle raises BMI |
| WHR | Waist ÷ hip | Apple vs pear shape; WHO sex-specific risk | Needs accurate hip measure; site consistency matters |
| WHtR | Waist ÷ height | Central adiposity; half-height rule | No hip context for pear vs apple classification |
Sample WHR Calculations
Example A – Woman (metric)
Waist 78 cm, hip 102 cm → WHR = 78 ÷ 102 = 0.76 (moderate risk, balanced/pear-leaning shape). Below WHO high-risk cutoff of 0.85.
Example B – Man (metric)
Waist 96 cm, hip 100 cm → WHR = 96 ÷ 100 = 0.96 (very high risk, apple shape). Exceeds WHO threshold of 0.90 — warrants metabolic screening discussion.
Example C – Man (imperial)
Waist 34 in, hip 40 in → WHR = 34 ÷ 40 = 0.85 (moderate risk, balanced shape). Approaching but not yet above WHO cutoff of 0.90.
Example D – Woman (pear shape)
Waist 70 cm, hip 105 cm → WHR = 70 ÷ 105 = 0.67 (low risk, pear shape). Classic gynoid distribution—still check BMI and waist cm for full picture.

Understanding Your WHR Category
Low risk
WHR well below WHO threshold. Pear or favorable balanced pattern. Maintain habits and periodic waist/hip checks.
Moderate
Approaching WHO cutoff. Watch waist trend; optimize nutrition and activity if WHR is rising.
High (WHO)
Above WHO threshold—apple shape likely. Lifestyle changes and metabolic screening often recommended.
Very high
Well above WHO cutoff. Strong central adiposity signal. Work with your healthcare team on comprehensive risk reduction.
Factors That Raise WHR
WHR rises when waist grows faster than hips—or when hips shrink disproportionately. Understanding drivers helps you target the right habits.
| Factor | Effect on WHR | Practical approaches |
|---|---|---|
| Calorie surplus & refined carbs | Preferential abdominal fat gain → higher WHR | Whole foods, fiber, limit sugary drinks |
| Sedentary lifestyle | Waist expands; hip muscle may not keep pace | Daily walking + resistance training (glutes/hips) |
| Poor sleep & chronic stress | Cortisol favors central fat storage | 7–9 h sleep; stress management; limit late-night eating |
| Age & menopause | Fat redistribution toward abdomen after 40–50 | Earlier screening; proactive waist-focused habits |
| Alcohol excess | Linked to central adiposity in many adults | Reduce intake; monitor waist trend |
| Genetics | Predisposition to android vs gynoid pattern | Cannot change genes—focus on modifiable lifestyle factors |
Strategies to Improve WHR (Overview)
If WHR is low or moderate
- Maintain activity, sleep, and protein intake
- Recheck WHR every 4–8 weeks—central fat can rise with age
- Still monitor blood pressure and glucose if family history is strong
- Pair with WHtR and BMI for complete screening
If WHR is high or very high (above WHO)
- Target sustainable waist reduction through calorie balance and activity
- 150+ min/week moderate activity plus resistance training 2–3×/week
- Limit ultra-processed foods and sugary drinks
- Consider 5–10% weight loss when clinically appropriate
- Discuss metabolic labs (glucose, lipids, BP) with your clinician
Lifestyle Recommendations by Focus Area
Nutrition
- Emphasize vegetables, legumes, whole grains, and lean protein
- Limit refined flour, sugary drinks, and deep-fried snacks
- Control portions—especially if waist is rising despite stable weight
- Alcohol moderation supports waist reduction in many adults
Activity
- 150+ minutes/week moderate aerobic activity (brisk walking counts)
- Resistance training 2–3×/week—builds glute/hip muscle and metabolic health
- Break up prolonged sitting every 30–60 minutes
- High-intensity intervals may reduce visceral fat when medically cleared
Screening
- WHR above WHO threshold: discuss fasting glucose, HbA1c, and lipids
- Check blood pressure at home or pharmacy
- Recalculate WHR every 4–8 weeks during lifestyle programs
- Use our Cardiovascular Risk Calculator for broader heart context
Sleep & stress
- 7–9 hours sleep supports appetite hormones and fat distribution
- Chronic stress elevates cortisol—linked to central fat gain
- Mindfulness, social support, and boundaries reduce stress eating
- Screen for sleep apnea if WHR is high with snoring or fatigue
Screening Tests to Consider If WHR Is High
WHR identifies distribution risk—it does not replace laboratory tests. Discuss these with your clinician when WHR exceeds WHO thresholds.
| Test | What it measures | Why it matters with high WHR |
|---|---|---|
| Fasting glucose / HbA1c | Blood sugar control | Central fat drives insulin resistance and prediabetes |
| Lipid panel | Total, LDL, HDL, triglycerides | Apple shape linked to atherogenic dyslipidemia in many cohorts |
| Blood pressure | Systolic / diastolic mmHg | Hypertension clusters with central obesity in metabolic syndrome |
| Liver enzymes | ALT, AST (and others) | Non-alcoholic fatty liver disease associates with high WHR |
WHR & Population Groups (Educational)
WHR cutoffs were largely validated in Europid and mixed adult cohorts. Some populations develop cardiometabolic disease at lower BMI and waist—distribution measures add context beyond weight alone.
- South Asian adults: Higher diabetes risk at lower BMI; central adiposity is common—WHR and waist cm screening are especially useful alongside IDRS tools like our Diabetes Risk Calculator.
- Postmenopausal women: Fat shifts from hips to abdomen—WHR may rise even with stable weight.
- Older adults: Sarcopenia can shrink hip girth while waist persists—WHR may overestimate risk if hip muscle is lost; clinical context helps.
- Athletes: Large gluteal muscles widen hips; lean cores may lower WHR despite high fitness—use body composition if unsure.
What If WHR Is 1.0 or Above?
A waist-to-hip ratio of 1.0 or higher means waist circumference is at least as large as hip circumference. If your ratio is 1.0 or above, re-checking your measurements is worthwhile—confirm waist and hip sites, use the same unit, and average two readings. However, this is not always a measurement error. In pronounced central obesity, overweight, obesity, metabolic syndrome, or elevated type 2 diabetes risk, waist can genuinely equal or exceed hip girth, and WHR ≥ 1.0 is a clinically meaningful apple-shaped pattern signaling high central adiposity.
When WHR May Mislead
- Wrong measurement site – Waist at navel vs narrowest point changes WHR; stay consistent.
- Hip measurement too low – Tape not at maximum buttock circumference inflates WHR artificially.
- Bloating – Meal timing, constipation, or cycle-related bloating temporarily enlarges waist.
- Pregnancy – Waist and hip grow for fetal development—do not apply adult WHR goals.
- Large hip muscles – Bodybuilders and sprinters may have wide hips from muscle, lowering WHR despite high fitness.
- Ascites or abdominal distension – Medical conditions, not adiposity.
Common WHR Measurement Mistakes
1. Sucking in your stomach
Artificially lowers waist and WHR. Measure after a normal exhale with relaxed abdomen.
2. Measuring hips over clothing
Bulky fabric skews hip reading. Use light clothing or measure over bare skin when possible.
3. Comparing to BMI alone
Normal BMI does not rule out high WHR. Check both when screening metabolic health at home.
4. Daily obsession with the tape
Waist and hip fluctuate day to day. Monthly or bi-monthly checks show real trends better than daily measurements.
5. Treating WHR as a diagnosis
WHR screens risk—it does not measure visceral fat volume. Imaging and labs confirm metabolic disease when needed.
The Science Behind WHR
Waist-to-hip ratio emerged from anthropometric epidemiology in the 1980s–1990s as researchers sought better predictors of cardiovascular outcomes than weight alone. Large cohort studies (including British Regional Heart Study and Nurses' Health Study follow-ups) showed WHR associated with myocardial infarction, stroke, and type 2 diabetes independent of BMI in many analyses. The WHO incorporated WHR into obesity risk assessment alongside waist circumference because distribution—not just total fat—matters for insulin resistance and atherogenic lipid profiles.
Modern imaging confirms that android fat patterns correlate with visceral adipose tissue volume on CT/MRI in population samples. WHR remains a practical home screening tool when imaging is unavailable. Clinical care still uses full metabolic syndrome criteria—waist plus blood pressure, glucose, triglycerides, and HDL—alongside tools like our Insulin Resistance (HOMA-IR) Calculator when fasting labs are available.
WHR & Waist Reference (Educational)
| Measure | Men | Women |
|---|---|---|
| WHR high risk (WHO) | > 0.90 | > 0.85 |
| Waist cm (metabolic, common) | < 94 healthy; ≥ 102 high | < 80 healthy; ≥ 88 high |
| WHtR goal (all adults) | Often < 0.5 (waist less than half height) | |
Limitations of WHR
- WHR does not measure visceral fat volume directly—imaging or clinical assessment is needed for diagnosis.
- Measurement technique matters—different waist sites produce different WHR values; stay consistent.
- Athletes with large hip musculature or very lean cores may get atypical ratios.
- Pregnancy, postpartum changes, and certain medical conditions alter waist and hip proportions.
- Adult WHR cutoffs are not validated for children and adolescents.
- WHR is a screening tool—it does not replace blood tests, imaging, or clinician judgment.
