Waist-to-Hip Ratio Calculator
Your waist-to-hip ratio can flag heart and diabetes risk that BMI misses, because it measures where your fat sits. This tool gives you both your waist-to-hip and waist-to-height ratios, with Indian thresholds. Reviewed by Dr. Ravi Sishir Reddy.

Calculate your ratios
Measure your waist at the navel and your hips at the widest point, after breathing out.
Nothing you enter is stored or sent anywhere. The calculation happens on your device.
What is the waist-to-hip ratio, and why does it matter?
The waist-to-hip ratio compares the fat around your middle to the fat around your hips. It matters because where you carry fat predicts risk better than how much you weigh. Fat stored around the abdomen and organs, the apple shape, is far more strongly linked to diabetes, high blood pressure, and heart disease than fat on the hips and thighs, the pear shape. This is why two people with the same BMI can have very different risk, and why a slim-looking person with a pot belly is not in the clear. The ratio puts a number on that difference.
What is a healthy waist-to-hip ratio?
The risk thresholds differ by sex. These are the widely used cut-offs.
| Risk level | Men | Women |
|---|---|---|
| Healthy | Below 0.90 | Below 0.80 |
| Increased risk | 0.90 to 0.99 | 0.80 to 0.84 |
| High risk | 1.0 and above | 0.85 and above |
The simpler check: keep your waist under half your height
There is an even simpler measure that many doctors now prefer, the waist-to-height ratio. The rule is easy to remember: your waist should be less than half your height. So a ratio below 0.5 is healthy, 0.5 to 0.6 signals increased risk, and 0.6 or above is high risk. It works across ages and body types and needs no chart, just your waist and your height in the same unit. This calculator gives you this ratio alongside the waist-to-hip ratio, so you get two independent readings of your abdominal fat.
Waist size and the India cut-off
Ratios aside, the plain waist measurement matters too, and the Indian thresholds are lower than Western ones. A waist above 90 cm in men and above 80 cm in women signals raised risk of diabetes and heart disease in Indians. This calculator flags your waist against these cut-offs as well. If your BMI looks fine but your waist or ratios are over the line, that is the thin-fat pattern common in Indians, and a reason to get a metabolic check rather than to relax. Our BMI calculator for Indians explains that pattern in more detail.
"I often measure the waist before I trust the weighing scale. A patient can have a normal BMI and still carry dangerous fat around the middle, and the waist-to-hip and waist-to-height ratios show it in seconds. For my Indian patients I use lower cut-offs, because the risk starts earlier. If the ratio is up, I check the sugar and lipids, because that is usually where the problem is already building."

What to do if your ratio is high
A raised ratio is a signal to check the rest, and to reduce abdominal fat, which responds well to change.
- Get a metabolic check. A raised ratio warrants a look at blood sugar, lipids, and blood pressure, where risk often shows first.
- Target abdominal fat. It responds to reduced sugar and refined carbohydrate, regular activity, and gradual weight loss.
- Read your ratio with your other numbers, including diabetes, cholesterol, and fatty liver risk, which travel together.
Because abdominal fat clusters with the rest of the metabolic picture, it is worth reading alongside our guides on type 2 diabetes, high cholesterol, and fatty liver. A general physician in Hyderabad can put the whole picture together.
Note: This calculator is a screening tool for adults. It is not for children or during pregnancy, when waist measurements do not apply the same way. Accurate measurement matters: measure the waist at the navel and hips at the widest point, after breathing out, without pulling the tape tight.
Frequently Asked Questions
What is a healthy waist-to-hip ratio?
A healthy waist-to-hip ratio is below 0.90 for men and below 0.80 for women. From 0.90 to 0.99 in men and 0.80 to 0.84 in women is increased risk, and 1.0 or above in men and 0.85 or above in women is high risk. The ratio matters because it reflects abdominal fat, which is more strongly linked to diabetes and heart disease than overall weight.
How do I measure my waist and hips correctly?
Measure your waist at the level of the navel, after breathing out, without pulling the tape tight or sucking in. Measure your hips at the widest part of the buttocks. Keep the tape level all the way around and use the same units for both. Accurate, relaxed measurement matters, because small errors change the ratio and its interpretation.
Is waist-to-hip ratio better than BMI?
They answer different questions and work best together. BMI screens overall weight for height, while the waist-to-hip ratio shows where fat sits, and abdominal fat is the more dangerous kind. Someone with a normal BMI can still have a high ratio, the thin-fat pattern common in Indians. Using both, plus your plain waist measurement, gives a fuller picture than any one number alone.
What is the waist-to-height ratio?
The waist-to-height ratio is your waist divided by your height. The simple rule is to keep your waist under half your height, so below 0.5 is healthy, 0.5 to 0.6 is increased risk, and 0.6 or above is high risk. Many doctors now favour it because it is easy, works across ages and body types, and needs no chart. This calculator shows it alongside the waist-to-hip ratio.
Why do Indians have lower waist cut-offs?
Indians tend to carry more abdominal and organ fat at the same measurement, and develop diabetes and heart disease at lower body sizes than Western populations. So the waist cut-offs are lower: above 90 cm in men and above 80 cm in women signal raised risk, compared with higher Western thresholds. This is why a waist that looks acceptable on a Western chart can still be a warning for an Indian.
Can I have a normal weight but a high waist ratio?
Yes, and it is common. A normal weight or BMI with a high waist ratio is the thin-fat pattern, where a healthy-looking body hides high abdominal fat and real metabolic risk. In this case the scale and BMI are falsely reassuring, and the waist ratios reveal the risk. If this is you, a simple blood test for sugar and lipids is the sensible next step.
How can I reduce my waist-to-hip ratio?
Abdominal fat responds well to change. Reducing sugar and refined carbohydrate, regular activity including both walking and some strength work, better sleep, and gradual weight loss all shrink waist fat and improve the ratio. There is no spot-reduction trick; overall fat loss is what lowers the waist. Even a modest reduction meaningfully lowers diabetes and heart risk, so the effort is worthwhile.
