What is a healthy waist-to-hip ratio?

According to the World Health Organization, a healthy WHR is below 0.90 for men and below 0.85 for women. Ratios above these thresholds indicate increased risk for cardiovascular disease, type 2 diabetes, and metabolic syndrome. A ratio of 0.80 or lower for women and 0.85 or lower for men is considered low risk.

How do I measure my waist-to-hip ratio?

Stand upright and use a flexible, non-stretch measuring tape. Measure your waist at the narrowest point (usually just above the belly button), then measure your hips at the widest point (the broadest part of the buttocks). Keep the tape level and parallel to the floor. Divide waist by hip measurement: WHR = waist ÷ hips.

What causes a high waist-to-hip ratio?

A high WHR is caused by excess abdominal (visceral) fat. Contributing factors include poor diet (high sugar, processed foods), sedentary lifestyle, chronic stress (elevated cortisol), inadequate sleep, alcohol consumption, genetics, hormonal changes (menopause, low testosterone), and certain medications. Visceral fat wraps around internal organs and is metabolically active, releasing inflammatory compounds.

What is the difference between apple and pear body shapes?

Apple-shaped bodies carry more fat around the waist and abdomen, resulting in a higher WHR and greater health risk. Pear-shaped bodies carry more fat around the hips and thighs, resulting in a lower WHR. Research consistently shows that apple-shaped fat distribution is associated with higher rates of heart disease, diabetes, and metabolic syndrome compared to pear-shaped distribution.

How can I lower my waist-to-hip ratio?

Reduce abdominal fat through: 1) a calorie deficit with whole foods, lean protein, and fiber, 2) regular exercise combining cardio and strength training, 3) reducing stress and improving sleep (cortisol drives belly fat storage), 4) limiting alcohol and processed sugar, 5) staying hydrated. Consistency over weeks and months is key — spot reduction is a myth.

Where should I measure my waist for WHR?

The WHO recommends measuring at the midpoint between the lower margin of the last palpable rib and the top of the iliac crest (hip bone). A simpler guideline used by many health organizations is to measure at the narrowest part of the torso, usually just above the belly button. Stand straight, exhale normally, and keep the tape level.

Does waist-to-hip ratio change with age?

Yes. WHR typically increases with age due to hormonal changes, loss of muscle mass, and redistribution of fat to the abdominal area. In women, menopause causes a shift from pear-shaped to apple-shaped fat distribution. In men, testosterone decline leads to more central fat storage. Regular exercise and a healthy diet can slow this age-related shift.

What waist-to-hip ratio indicates obesity?

The WHO defines abdominal obesity as WHR ≥ 0.90 for men and ≥ 0.85 for women. This is associated with substantially increased risk of metabolic complications. However, even ratios slightly below these cutoffs (0.85–0.90 for men, 0.80–0.85 for women) may indicate moderate risk, especially when combined with elevated waist circumference.

Can I have a normal BMI but a high waist-to-hip ratio?

Yes. This is sometimes called 'normal weight central obesity' or 'skinny fat.' A person can have a healthy BMI but carry disproportionate fat around the waist. Research from the Mayo Clinic found that normal-weight individuals with central obesity had higher mortality risk than those who were overweight by BMI but had normal fat distribution. This is why WHR is a valuable complement to BMI.

Waist-to-Hip Ratio Calculator

Measure your waist-to-hip ratio to assess abdominal fat distribution and health risk. Uses WHO and clinical guidelines.

A healthy waist-to-hip ratio (WHR) is below 0.90 for men and below 0.85 for women, according to the World Health Organization. WHR measures where your body stores fat — abdominal fat (apple shape) carries higher health risks than hip/thigh fat (pear shape). Enter your waist and hip measurements below to calculate your ratio and risk level.

Based on World Health Organization (WHO) guidelines and clinical research. Formula: WHR = waist circumference ÷ hip circumference.

Calculate Your Waist-to-Hip Ratio

Gender

Unit

Waist Circumference (narrowest point, above belly button)

Hip Circumference (widest part of buttocks)

Quick Answer: Waist-to-Hip Ratio at a Glance

•Formula: WHR = Waist circumference ÷ Hip circumference.
•Low risk (men): WHR below 0.90 (WHO guideline).
•Low risk (women): WHR below 0.85 (WHO guideline).
•Apple vs. Pear: Abdominal fat (apple shape) carries higher cardiovascular and metabolic risk.
•Better than BMI? WHR shows where fat is stored, not just total weight. Use both metrics together.

What is waist-to-hip ratio?

Waist-to-hip ratio (WHR) is a simple measurement that compares the circumference of your waist to your hips. It is calculated by dividing your waist measurement by your hip measurement. WHR is used by the World Health Organization, clinicians, and researchers as an indicator of abdominal obesity and a predictor of health risks including cardiovascular disease, type 2 diabetes, hypertension, and metabolic syndrome. Unlike BMI, which only considers total weight relative to height, WHR reveals how fat is distributed across your body — a factor that strongly influences health outcomes.

Waist-to-hip ratio chart (WHO thresholds)

The table below shows WHO-defined health risk categories based on WHR for men and women. These thresholds are widely used in clinical practice worldwide.

Waist-to-Hip Ratio Health Risk Categories (WHO)
Health Risk	Men (WHR)	Women (WHR)	Associated Risk
Low	< 0.90	< 0.80	Normal fat distribution, lowest health risk
Moderate	0.90 – 0.99	0.80 – 0.84	Increased risk of metabolic complications
High	≥ 1.00	≥ 0.85	Substantially increased risk of heart disease, diabetes

WHR vs. BMI vs. waist circumference: which is best?

No single body measurement tells the full story. Each metric captures different aspects of body composition and health risk. The table below compares the three most commonly used clinical assessments.

Body Measurement Comparison
Metric	Measures	Strengths	Limitations
WHR	Fat distribution (waist vs. hips)	Best predictor of cardiovascular risk; accounts for body shape	Requires two measurements; slightly less intuitive
BMI	Weight relative to height	Simple, widely used, good for population screening	Doesn't distinguish fat from muscle; ignores fat location
Waist circumference	Abdominal fat volume	Single measurement; strong metabolic risk predictor	Doesn't account for hip/frame size; varies by ethnicity

For the most complete picture, clinicians recommend using all three metrics together. A person with normal BMI but high WHR ("normal weight central obesity" or "skinny fat") may have higher mortality risk than someone who is overweight by BMI but has a healthy fat distribution (Mayo Clinic, 2014).

How to measure your waist and hips correctly

Accurate measurement is essential for meaningful results. Follow these clinical guidelines:

Waist Measurement

Stand upright, feet shoulder-width apart
Find the narrowest point of your torso (usually above belly button)
Wrap tape level and parallel to the floor
Keep tape snug, not tight
Exhale normally and read the measurement

Hip Measurement

Stand upright with feet together
Find the widest part of your buttocks
Wrap tape level and parallel to the floor
Keep tape snug, not tight
Record the measurement in the same units

Apple vs. pear body shape

Body fat distribution falls broadly into two patterns, each with different health implications:

Feature	Apple Shape (Android)	Pear Shape (Gynoid)
Fat location	Abdomen, waist, upper body	Hips, thighs, buttocks
WHR	Higher (≥ 0.85 women, ≥ 0.90 men)	Lower (< 0.80 women, < 0.85 men)
Fat type	Visceral (around organs)	Subcutaneous (under skin)
Cardiovascular risk	Higher	Lower
Diabetes risk	Higher	Lower
More common in	Men, post-menopausal women	Pre-menopausal women

Healthy waist circumference by gender

Independent of WHR, waist circumference alone is a strong predictor of health risk. The following thresholds are used alongside WHR for a more complete assessment:

Waist Circumference Risk Thresholds
Risk Level	Men	Women
Low risk	< 94 cm (37 in)	< 80 cm (31.5 in)
Increased risk	94–102 cm (37–40 in)	80–88 cm (31.5–34.6 in)
Substantially increased	> 102 cm (40 in)	> 88 cm (34.6 in)

Health risks of a high waist-to-hip ratio

Excess abdominal (visceral) fat is metabolically active and releases inflammatory compounds, hormones, and fatty acids directly into the portal vein. This contributes to a cluster of conditions collectively known as metabolic syndrome. Research consistently links elevated WHR to:

Cardiovascular disease — increased risk of heart attack, stroke, and atherosclerosis
Type 2 diabetes — visceral fat impairs insulin sensitivity
Hypertension — abdominal obesity is independently associated with elevated blood pressure
Dyslipidemia — unfavorable cholesterol profile (high triglycerides, low HDL)
Metabolic syndrome — cluster of risk factors multiplying disease probability
Certain cancers — colorectal, breast (post-menopausal), and endometrial cancer risk increases
Sleep apnea — central obesity is the strongest predictor of obstructive sleep apnea

How to reduce your waist-to-hip ratio

Spot reduction is a myth — you cannot target fat loss from a specific area through exercise alone. However, consistent lifestyle changes effectively reduce visceral fat and improve WHR over time:

Strategy	What to Do	Why It Works
Calorie deficit	Eat 300–500 kcal below maintenance	Creates fat loss; visceral fat is often lost first
Cardio exercise	150+ min/week moderate or 75+ min vigorous	Burns calories, preferentially reduces visceral fat
Strength training	2–3 sessions/week, full-body	Builds lean mass, raises resting metabolic rate
High-protein diet	1.6–2.2 g protein per kg body weight	Preserves muscle during fat loss, increases satiety
Reduce sugar & alcohol	Limit added sugars to < 25 g/day; moderate alcohol	Excess sugar and alcohol promote visceral fat storage
Sleep & stress	7–9 hours sleep; stress management techniques	Cortisol drives fat storage in the abdominal area

Key Takeaways

WHR = waist ÷ hips. Healthy: < 0.90 men, < 0.85 women (WHO).
WHR measures where fat is stored — more informative than BMI for health risk.
Apple shape (high WHR) carries higher cardiovascular and diabetes risk than pear shape.
You can have a normal BMI but a dangerous WHR ("skinny fat" or normal weight central obesity).
Visceral fat responds well to calorie deficit, exercise, and stress reduction.
Use WHR alongside BMI and waist circumference for the most complete health assessment.
