This waist to hip ratio calculator tells you your WHR — a single number that reveals how your body fat is distributed and what that distribution means for your health risk.
Unlike BMI, which only compares your weight to your height, waist to hip ratio measures where your body actually stores fat. And where fat is stored matters far more than how much you weigh. Two people with the same BMI can have very different health profiles depending on whether their fat sits around their waist or their hips.
What your WHR means:
Your waist to hip ratio is a measure of fat distribution — not total fat. A higher ratio means more fat is concentrated around your abdomen. A lower ratio means more fat is distributed around your hips and thighs.
Abdominal fat — the fat that surrounds your internal organs — is metabolically active in ways that subcutaneous fat around the hips is not. This is why WHR predicts cardiovascular and metabolic health risk more accurately than body weight alone.
What is waist to hip ratio — and why does it matter more than weight?
Waist to hip ratio (WHR) is the measurement of your waist circumference divided by your hip circumference. The result is a decimal number that tells you the shape of your body and, more importantly, where your body stores its fat.
This matters because fat stored in different places carries different health implications. Fat stored around the abdomen — visceral fat — surrounds your internal organs and is metabolically active. It releases inflammatory compounds, affects insulin sensitivity, raises blood pressure, and is strongly associated with cardiovascular disease, type 2 diabetes, and metabolic syndrome.
Fat stored around the hips, buttocks, and thighs — subcutaneous fat — does not carry the same metabolic risk. In fact, research suggests that pear-shaped fat distribution may even have some protective effects compared to apple-shaped distribution.
Your BMI tells you whether your total weight is proportionate to your height. Your WHR tells you something BMI cannot: whether the fat you carry is concentrated in the most dangerous place. A person with a normal BMI can still have a high WHR — and therefore elevated cardiovascular risk — while a person with an overweight BMI but a low WHR may have far lower risk than their weight alone would suggest.
This is why the World Health Organization recommends WHR alongside BMI as a complementary measure of health risk, and why many clinicians consider it a more practical tool than BMI for predicting disease outcomes.
How to calculate waist to hip ratio — the formula
The waist to hip ratio formula is straightforward:
WHR = Waist circumference divided by Hip circumference
Both measurements must be in the same unit — either both in centimeters or both in inches. The ratio is the same either way.
Example: Waist of 80 cm and hip of 100 cm gives a WHR of 80 divided by 100 = 0.80.
Example: Waist of 34 inches and hip of 40 inches gives a WHR of 34 divided by 40 = 0.85.
The result is always a number less than or close to 1.0 for most people. A result above 1.0 means your waist measurement is larger than your hip measurement — this falls in the high health risk category for both men and women.
How to measure correctly for an accurate WHR
How to measure your waist
Your waist measurement for WHR purposes is not the same as your trouser waist size. For an accurate reading:
Stand relaxed, feet together. Find the narrowest point of your torso — this is typically just above your belly button, roughly halfway between the bottom of your ribcage and the top of your hip bones. Exhale normally and measure at this point. Do not hold your breath in or suck your stomach in — a natural, relaxed breath gives the accurate measurement this formula requires.
Keep the tape horizontal and parallel to the floor all the way around. It should be snug against your skin but not compressing it.
How to measure your hips
Stand with your feet together. Find the widest point of your hips and buttocks — this is typically 7 to 9 centimeters below your hip bones, at the fullest part of your gluteal muscles.
Measure around this widest point with the tape horizontal and level all the way around. This measurement is the largest circumference around your lower body, not the circumference at the hip bones themselves.
When to measure
For the most consistent readings, measure in the morning before eating or drinking, wearing minimal clothing. Avoid measuring immediately after a large meal, heavy exercise, or at the end of the day when bloating tends to be higher.
If you are tracking WHR over time to measure progress, measure under the same conditions each time for meaningful comparisons.
Waist to hip ratio chart — what your number means
WHR chart for women
The World Health Organization defines the following WHR risk categories for women:
Low health risk: WHR below 0.80. Fat is distributed primarily around the hips and thighs. This pear-shaped distribution carries the lowest metabolic risk.
Moderate health risk: WHR between 0.80 and 0.84. Fat distribution is becoming more central. Health risk is elevated compared to the low range.
High health risk: WHR of 0.85 and above. Fat is concentrated around the abdomen. This is the WHO threshold for abdominal obesity in women and is associated with significantly elevated cardiovascular and metabolic risk.
WHR chart for men
For men, the thresholds are higher because men naturally carry more abdominal fat than women at the same total body fat percentage:
Low health risk: WHR below 0.90. Body fat is distributed relatively evenly. Metabolic risk is in the lower range.
Moderate health risk: WHR between 0.90 and 0.99. Increasing concentration of abdominal fat. Health risk is elevated.
High health risk: WHR of 1.00 and above. Waist circumference equals or exceeds hip circumference. This is the WHO threshold for abdominal obesity in men and carries the highest associated health risk.
WHR and body shape — apple versus pear
Your WHR determines what is commonly described as your body shape — though this is a simplified way of expressing what is really a health risk pattern rather than an aesthetic classification.
A pear-shaped body — more volume below the waist than above — corresponds to a lower WHR. Fat sits in the hips, thighs, and buttocks. This distribution is more common in women and carries lower metabolic risk.
An apple-shaped body — more volume around the waist than the hips — corresponds to a higher WHR. Fat is concentrated in the abdominal region. This distribution is more common in men and in women after menopause, and carries meaningfully higher risk for cardiovascular disease, type 2 diabetes, hypertension, and insulin resistance.
These shapes are not fixed by genetics alone. Lifestyle factors — diet, physical activity, sleep, and stress — all influence where the body deposits and stores fat over time. A higher WHR can improve with sustained lifestyle changes, particularly those that target abdominal fat specifically.
Waist to hip ratio for Filipinos — what to know
Waist to hip ratio is particularly relevant for Filipino adults because Asian populations tend to accumulate visceral abdominal fat at lower BMI values than Western populations. This means a Filipino adult can have a normal BMI but still carry metabolically significant abdominal fat — a pattern that WHR captures where BMI misses.
Research on Asian body composition consistently shows that health risks associated with abdominal obesity begin at lower absolute measurements in Asian individuals compared to Western reference populations. The WHO cutoff values used in this calculator apply globally, but Filipino adults should be aware that risks may begin to appear even before these thresholds are crossed.
For practical context:
Average Filipino male waist circumference is approximately 80 to 85 cm. Average Filipino hip circumference for men is approximately 92 to 96 cm. This gives an approximate WHR of 0.87 to 0.89 — in or approaching the moderate risk range for most Filipino men.
Average Filipino female waist circumference is approximately 72 to 78 cm. Average Filipino hip circumference for women is approximately 90 to 96 cm. This gives an approximate WHR of 0.78 to 0.82 — straddling the low to moderate risk boundary for most Filipino women.
If you are concerned about your WHR result and its implications for your health, speaking with your doctor about a broader metabolic health assessment is the most useful next step.
How to reduce waist to hip ratio
Reducing your WHR means reducing abdominal fat relative to hip fat. Since you cannot meaningfully increase your hip circumference through training alone, the practical goal is reducing waist circumference.
The most effective approaches for reducing abdominal fat:
Calorie deficit through diet. Abdominal fat responds well to a sustained calorie deficit. Even moderate fat loss — 5 to 10 percent of body weight — produces measurable reductions in waist circumference. Use our Calorie Intake Calculator to find your daily calorie target.
Resistance training. Building muscle through strength training increases resting metabolic rate and improves insulin sensitivity — both of which reduce the tendency to store fat abdominally. Resistance training combined with a calorie deficit produces better body composition outcomes than diet alone.
Cardiovascular exercise. Regular aerobic exercise reduces visceral fat specifically, independent of total weight loss. This makes cardio a particularly effective tool for improving WHR even when overall weight change is modest.
Stress management and sleep. Cortisol — the stress hormone — specifically promotes abdominal fat storage. Chronically elevated cortisol from poor sleep or high stress directly worsens WHR over time. Addressing sleep quality and stress is not optional when the goal is reducing waist circumference.
Dietary composition. Reducing highly processed foods, refined carbohydrates, and added sugars specifically helps reduce abdominal fat accumulation, beyond the effect of total calorie reduction alone.
Frequently asked questions
How do I calculate my waist to hip ratio?
Measure your waist at the narrowest point — just above your belly button. Measure your hips at the widest point of your buttocks. Divide your waist measurement by your hip measurement.
Example: waist 80 cm divided by hips 100 cm = WHR of 0.80. Our waist to hip ratio calculator does this automatically — enter your two measurements and your WHR and health risk category appear instantly.
What is a healthy waist to hip ratio?
For women, a healthy WHR is below 0.80. For men, a healthy WHR is below 0.90. These are the World Health Organization thresholds for low health risk.
A WHR above 0.85 for women or above 1.00 for men is the WHO definition of abdominal obesity and is associated with significantly elevated cardiovascular and metabolic health risk.
Is waist to hip ratio better than BMI?
WHR and BMI measure different things. BMI measures weight relative to height — it tells you whether your total weight is proportionate to your frame. WHR measures fat distribution — it tells you where your body stores fat.
For predicting cardiovascular and metabolic health risk specifically, research generally shows WHR is a stronger predictor than BMI. A person can have a normal BMI but a high WHR — meaning their weight is not excessive but their fat is concentrated in the most dangerous location. BMI would miss this risk entirely.
Using both together gives the most complete picture.
Can WHR improve without losing weight?
Yes — body composition can shift even when total weight does not change significantly. Resistance training builds muscle, which increases the hip and thigh circumference slightly while reducing waist circumference through improved insulin sensitivity and reduced abdominal fat. The result can be a meaningfully lower WHR at the same body weight.
However, the most effective approach for most people is combining resistance training with a modest calorie deficit to reduce total body fat while preserving or building muscle.
How often should I check my WHR?
Checking every four to six weeks gives you enough time for meaningful changes to occur between measurements. Checking too frequently — daily or weekly — tends to show measurement variation rather than genuine change, which can be discouraging.
Measure under consistent conditions each time — same time of day, same clothing, same technique. The trend over months matters far more than any single measurement.
