Waist to Hip Ratio Calculator
What this means
Based on WHO thresholds. This is a screening indicator, not a diagnosis. Measure at the same time of day with relaxed breathing. See a doctor for a full assessment.
Your waist to hip ratio (WHR) tells you where your body stores fat, which predicts heart and metabolic risk better than weight alone. Divide your waist by your hips and you get a single number: below 0.80 is healthy for women, below 0.90 for men. This calculator does the math in seconds and shows your risk band using the same World Health Organization thresholds doctors use. It works in inches or centimeters, no conversion needed. Below the tool you will find what your exact ratio means, why 0.7 is called the ideal, healthy ranges for men and women, and how to measure your waist and hips the right way.
A higher ratio usually means more fat stored around the waist, which is linked to higher health risks. For a more comprehensive view, you can also check your Waist to Height Ratio to understand how waist size relates to overall body health.
What Is Waist to Hip Ratio?
Waist to hip ratio is a simple number that shows how your waist size compares to your hip size.
It is calculated by dividing your waist measurement by your hip measurement.
This makes it more useful than weight alone.
The ratio helps show where your body stores fat.
More fat around the waist usually signals higher health risk than fat around the hips.
That is why waist to hip ratio is often used alongside BMI and body fat percentage.
It gives a clearer picture of body shape and health.
How to Calculate Waist to Hip Ratio
To calculate waist to hip ratio, divide your waist measurement by your hip measurement.
Waist to Hip Ratio Formula:
WHR = Waist Circumference ÷ Hip Circumference
Example:
If your waist is 80 cm and your hips are 100 cm:
80 ÷ 100 = 0.80
This means your waist to hip ratio is 0.80.
You can calculate this manually, but using a Waist to Hip Ratio Calculator is faster and avoids mistakes.
It also works with both cm and inches, so you do not need to convert units.
Waist to Hip Ratio Worked Examples
A few examples so you can check your own number in either unit:
- Woman, 75 cm waist, 95 cm hips: 75 ÷ 95 = 0.79. Below 0.80, so low risk.
- Woman, 32 in waist, 38 in hips: 32 ÷ 38 = 0.84. In the 0.80 to 0.84 band, so increased risk for a woman.
- Man, 34 in waist, 40 in hips: 34 ÷ 40 = 0.85. Below 0.90, so low risk for a man.
- Man, 90 cm waist, 100 cm hips: 90 ÷ 100 = 0.90. This crosses into increased risk for a man.
The unit does not matter because both numbers cancel out. Inches or centimeters give the same ratio, as long as you measure waist and hips in the same unit. To simplify or scale any two numbers into a plain ratio, the ratio calculator does it in one step.
How to Measure Waist and Hips Correctly
Accurate measurements are important for a reliable waist to hip ratio.
How to measure your waist
- Stand straight and relax your stomach
- Measure around the narrowest part of your waist
- This is usually just above the belly button
- Do not suck in your stomach
How to measure your hips
- Stand with your feet together
- Measure around the widest part of your hips and buttocks
- Keep the tape level and snug, not tight
Use a soft measuring tape and measure on bare skin or thin clothing.
For best results, take the measurement once or twice and use the average.
Healthy Waist to Hip Ratio Ranges (Men and Women)
Healthy waist to hip ratio thresholds differ by gender because men and women store fat differently. These are the World Health Organization risk bands, set out in WHO's 2011 expert consultation report on waist circumference and waist-hip ratio, and they are the same ones the calculator uses.
| Risk Level | Women | Men |
|---|---|---|
| Low risk (healthy) | Below 0.80 | Below 0.90 |
| Increased risk | 0.80 to 0.84 | 0.90 to 0.99 |
| High risk | 0.85 and above | 1.0 and above |
A higher ratio means more fat around the waist, which is linked to heart disease, type 2 diabetes, and metabolic problems. A lower ratio means more fat around the hips, which carries less risk. This is why two people at the same weight can face very different health outcomes: fat location matters more than the number on the scale. Use these bands as a guide, not a diagnosis, and track changes over weeks rather than reading too much into one measurement.
What Does Your Exact Waist to Hip Ratio Mean?
Most people arrive with a specific number. Because the healthy cutoff differs by gender, here is what the common ratios mean for each:
| Your Ratio | For Women | For Men |
|---|---|---|
| 0.60 to 0.69 | Low risk (healthy) | Low risk (healthy) |
| 0.70 | Low risk (often called ideal) | Low risk (healthy) |
| 0.75 | Low risk (healthy) | Low risk (healthy) |
| 0.80 | Increased risk (just over the line) | Low risk (healthy) |
| 0.85 | High risk | Low risk (healthy) |
| 0.90 | High risk | Increased risk |
| 1.0 and above | High risk | High risk |
Notice that the same ratio lands differently for men and women. A 0.85 ratio is high risk for a woman but still healthy for a man. Always read your number against your own gender's band.
Why Is 0.7 Called the Ideal Waist to Hip Ratio?
A waist to hip ratio near 0.70 comes up constantly in research on body shape and attractiveness. Studies across many cultures have found that a ratio around 0.7 in women is widely rated as attractive, and it also happens to line up with a lower-risk health profile. That overlap is why 0.7 gets called the "golden" or "ideal" ratio.
To put it in real measurements, a 0.70 ratio looks like:
- Waist 28 in, hips 40 in = 0.70
- Waist 26 in, hips 37 in = 0.70
- Waist 24 in, hips 34 in = 0.71
Two things worth keeping in mind. First, "attractive" and "healthy" are not the same thing, even though they overlap here. For health, any ratio below 0.80 for women or 0.90 for men sits in the low-risk band, so you do not need to hit exactly 0.7. Second, your ratio is shaped heavily by bone structure and genetics, not just fat, so chasing an exact hourglass number is often unrealistic. Use it as a rough shape reference, and use the health bands above for anything medical.
What Does a Low Waist to Hip Ratio Mean?
A low waist to hip ratio (well below 0.80 for women or 0.90 for men) means your waist is noticeably smaller than your hips. Health-wise, that is a good sign: it points to less abdominal fat and lower risk of heart and metabolic disease. In body-shape terms it describes a curvier, more hourglass profile. A very low ratio driven by naturally wide hips is normal and not a concern on its own.
Waist to Hip Ratio vs BMI vs Body Fat
Waist to hip ratio, BMI, and body fat percentage measure different things.
BMI looks only at height and weight.
It does not show where fat is stored.
Body fat percentage measures how much of your body is fat.
It gives more detail but often needs special tools or formulas.
Waist to hip ratio focuses on fat distribution.
It shows whether fat is stored around the waist or hips.
This is why waist to hip ratio is often better at predicting health risk than BMI alone.
It highlights belly fat, which is more strongly linked to heart disease and diabetes.
Using these measurements together gives a clearer view of overall health.
Waist to Hip Ratio and Health Risks
Your waist to hip ratio is closely linked to long-term health.
A higher ratio usually means more fat stored around the waist.
This type of fat is known as abdominal or belly fat.
Research shows that a high waist to hip ratio is associated with:
- Higher risk of heart disease
- Increased chance of type 2 diabetes
- Blood pressure issues
- Metabolic health problems
Fat stored around the hips is generally less harmful than fat around the waist.
That is why two people with the same weight can have very different health risks.
Monitoring your waist to hip ratio can help you spot potential issues early.
Small improvements over time can make a meaningful difference to your health.
How to Improve Waist to Hip Ratio
Improving your waist to hip ratio usually means reducing fat around the waist while maintaining healthy muscle mass.
Here are practical ways to improve it:
Focus on fat loss
- Create a small calorie deficit
- Avoid crash dieting
Prioritize strength training
- Build muscle in the lower body and core
- Muscle helps improve body shape over time
Improve daily nutrition
- Eat enough protein
- Balance carbs and fats instead of cutting them completely
Stay active and consistent
- Regular walking and movement help reduce belly fat
- Consistency matters more than short-term changes
Waist to hip ratio changes gradually.
Tracking it every few weeks gives a better picture than daily measurements.

Frequently Asked Questions (FAQs)
What is waist to hip ratio?
Waist to hip ratio compares your waist size to your hip size. It helps show where your body stores fat and is often used to assess health risk related to belly fat.
How to measure waist and hips?
Measure your waist around the narrowest part of your torso, usually just above the belly button. Measure your hips around the widest part of your hips and buttocks, keeping the tape level.
How to calculate waist to hip ratio?
Divide your waist measurement by your hip measurement.
For example, if your waist is 75 cm and your hips are 95 cm, your waist to hip ratio is 0.79.
What is the difference between waist and hips?
Your waist is the narrowest part of your torso, usually just above the belly button. Your hips are the widest part around your buttocks and hip bones, lower down. In the ratio, waist is the top number and hips is the bottom number, so waist ÷ hips. Measuring the wrong spots is the most common reason people get an off result.
