What Is Waist-to-Hip Ratio?
Waist-to-hip ratio (WHR) is your waist circumference divided by your hip circumference — a simple number that describes where your body tends to store fat, rather than how much fat you have overall.
Two people can have the exact same weight, BMI, or even body fat percentage and still carry that fat very differently — one more around the waist and abdomen, the other more around the hips and thighs. WHR is the metric built specifically to capture that difference, because where fat is stored turns out to matter almost as much as how much there is.
WHR vs. BMI vs. Body Fat Percentage
These three numbers each answer a different question, and using them together gives a far more complete picture than any one alone:
- BMI asks: is your weight reasonable for your height? (See our BMI guide, including why standard BMI cutoffs understate risk for Indian bodies.)
- Body fat percentage asks: how much of your weight is actually fat versus lean mass? (See our Body Fat Percentage guide.)
- Waist-to-hip ratio asks: where on your body is that fat concentrated?
None of the three replaces the others — a person can have a "normal" BMI and still have a high WHR (more abdominal fat than their weight alone would suggest), which is one reason health bodies increasingly recommend checking more than just BMI.
How to Measure Your Waist and Hip Circumference
Getting an accurate WHR starts with measuring correctly:
Waist: Measure at the narrowest point of your torso, usually roughly level with your navel and just above your belly button — not at the top of your hip bone and not wherever your pants happen to sit. Stand relaxed, breathe out normally (don't suck in), and keep the tape snug but not compressing the skin.
Hip: Measure around the widest part of your hips and buttocks, keeping the tape parallel to the floor.
Take each measurement 2-3 times and use the average, since a single reading can be thrown off by tape placement or posture.
WHR Formula & How to Calculate It
The formula is straightforward:
Waist-to-Hip Ratio = Waist circumference ÷ Hip circumference
Example: A waist of 80 cm and hips of 100 cm gives a WHR of 80 ÷ 100 = 0.80.
Both measurements need to be in the same unit (both cm or both inches) — the ratio itself is unitless, which is why WHR can be compared across people regardless of whether they measured in cm or inches.
Use our Waist-to-Hip Ratio Calculator to skip the arithmetic — enter both measurements and get your ratio and risk category instantly.
Healthy Waist-to-Hip Ratio Chart
The World Health Organization defines WHR risk categories separately for men and women, since healthy fat distribution naturally differs by sex:
| Risk Level | Men | Women |
|---|---|---|
| Low risk | 0.90 or below | 0.80 or below |
| Moderate risk | 0.91 – 0.99 | 0.81 – 0.84 |
| High risk | 1.0 or above | 0.85 or above |
A WHR above these thresholds indicates more abdominal (visceral) fat relative to hip fat — a pattern associated with higher cardiovascular and metabolic risk, independent of overall weight.
Waist Circumference on Its Own
Waist circumference by itself — without factoring in hips at all — is also a recognized, independent health indicator, and it's worth knowing both numbers rather than only the ratio. The WHO and other health bodies flag increased risk above:
| Increased Risk | Substantially Increased Risk | |
|---|---|---|
| Men | ≥94 cm (~37 in) | ≥102 cm (~40 in) |
| Women | ≥80 cm (~31.5 in) | ≥88 cm (~35 in) |
Waist circumference and WHR usually tell a similar story, but not always — someone with narrow hips can have a "good" WHR while still carrying enough abdominal fat to cross the waist-circumference risk threshold, which is why checking both numbers gives a more reliable read than either alone.
Apple vs. Pear Body Shape
WHR is essentially a formal way of describing what's often called "apple" versus "pear" body shape:
- Apple shape (higher WHR): Fat concentrated more around the abdomen and waist relative to the hips. This pattern carries higher cardiovascular and metabolic risk.
- Pear shape (lower WHR): Fat concentrated more around the hips and thighs relative to the waist. Generally associated with lower cardiovascular risk than the apple pattern, at a comparable overall body fat level.
Body shape is influenced by genetics, sex, and hormones, and isn't something you can fully change — but WHR can still shift meaningfully with fat loss, particularly loss of visceral (abdominal) fat, which tends to respond well to a consistent calorie deficit and regular activity.
Why Waist-to-Hip Ratio Matters for Health
Abdominal fat — the kind that raises your waist measurement and your WHR — behaves differently in the body than fat stored elsewhere. It sits closer to and around internal organs (visceral fat) and is more metabolically active, which is linked to a higher risk of type 2 diabetes, high blood pressure, and cardiovascular disease.
Some research has found WHR to be at least as strong a predictor of cardiovascular risk as BMI, and in some studies a stronger one, precisely because it captures this distribution pattern that BMI can't see at all.
This is exactly why WHR is a useful number to check alongside BMI and body fat percentage rather than in isolation — someone in a "normal" BMI range with a high WHR may still be carrying meaningful health risk that BMI alone would miss entirely.
The "Ideal" Waist-to-Hip Ratio in Attractiveness Research
You'll also see WHR discussed in a very different context — research in evolutionary psychology, most notably by researcher Devendra Singh in the 1990s, proposed that a WHR around 0.7 in women is widely perceived as attractive across cultures, theorized to be an unconscious signal of fertility and health. This research is genuine and often cited, which is why "0.7 waist to hip ratio" and "attractive waist to hip ratio" get searched fairly often — but it's worth keeping in perspective: a specific ratio associated with attractiveness in psychology studies isn't a health target, and chasing it isn't the point of measuring your own WHR. The health-risk categories above are the numbers actually worth tracking.

FAQs
What is a healthy waist-to-hip ratio? According to WHO, a WHR of 0.90 or below is low risk for men, and 0.80 or below is low risk for women. Ratios above 1.0 (men) or 0.85 (women) are considered high risk.
How do I calculate my waist-to-hip ratio? Divide your waist circumference by your hip circumference, measured in the same units. For example, an 80 cm waist and 100 cm hips give a WHR of 0.80. Use the Waist-to-Hip Ratio Calculator for an instant result.
Where exactly do I measure my waist and hips? Measure your waist at its narrowest point, roughly at navel level, breathing out normally without sucking in. Measure your hips at the widest part of your hips and buttocks, with the tape parallel to the floor.
Is waist-to-hip ratio better than BMI? They measure different things. WHR captures where fat is distributed on your body, which BMI can't see at all, and some research suggests WHR predicts cardiovascular risk at least as well as BMI. The most complete picture comes from checking both together, not choosing one over the other.
What is a healthy waist circumference? The WHO flags increased risk above 94 cm (about 37 in) for men and 80 cm (about 31.5 in) for women, with substantially increased risk above 102 cm (about 40 in) for men and 88 cm (about 35 in) for women.
What's the difference between apple and pear body shapes? Apple-shaped bodies carry more fat around the waist and abdomen (higher WHR) and carry higher associated health risks. Pear-shaped bodies carry more fat around the hips and thighs (lower WHR) and are generally associated with lower cardiovascular risk at a similar overall body fat level.
Can I change my waist-to-hip ratio? Body shape has a genetic and hormonal component you can't fully change, but WHR can shift meaningfully with fat loss, particularly loss of visceral (abdominal) fat — which responds well to a consistent calorie deficit and regular physical activity over time.
Why is 0.7 waist-to-hip ratio often mentioned? It comes from psychology research (notably by Devendra Singh in the 1990s) proposing that a WHR near 0.7 in women is widely perceived as attractive across cultures. It's a research finding about perception, not a health target — the WHO risk categories above are the numbers relevant to your health.
