Waist circumference is the measurement taken around the abdomen at the level of the umbilicus (belly button). Measuring your waist circumference may help you understand certain health risks related to obesity. Health experts commonly use waist measurement to screen patients for possible weight-related health problems. While a helpful tool, waist size is just one indicator that may point to certain health conditions, and it is not used to singularly diagnose any conditions or diseases.

While health experts and physicians may use this method in-office, you can also measure your own waist circumference at home.

Waist Circumference

Measuring the size (or circumference) of your waist can help you understand your risk for certain weight-related health conditions. While waist circumference alone cannot indicate that you have a medical condition or that you’ll develop one in the future, it can help you and your healthcare provider to determine where fat is located on your body and if that body fat may cause health problems for you in the future like heart disease or type 2 diabetes.

According to the National Institutes of Health (NIH), if more fat is located around your waist rather than around your hips, you are at higher risk for conditions including heart disease and type 2 diabetes. You can use your waist measurement to calculate your waist-hip ratio (WHR), which provides another screening tool for weight-related disease risk.

Your healthcare provider may also use a body mass index (BMI) measurement as a health indicator. However, a 2019 study concluded that both hip-adjusted waist circumference and waist-to-height ratio were stronger indicators of health and potential health conditions than BMI.

Body Mass Index (BMI) is a dated, biased measure that doesn’t account for several factors, such as body composition, ethnicity, race, gender, and age.

Despite being a flawed measure, BMI is widely used today in the medical community because it is an inexpensive and quick method for analyzing potential health status and outcomes.

How to Measure Your Waist Circumference

To measure waist circumference correctly, you should use a flexible tape measure that is not elastic. Remove any bulky clothing that can add padding around your abdomen and stand, placing a tape measure above your hip bones.

Follow these steps to measure your waist:

1. Stand up to get an accurate waist measurement. The tape measure should not stretch when you are taking the measurement.
2. Wrap the tape measure around the widest part of your stomach, across your belly button. The tape measure should rest gently on your skin.
3. Once the tape measure is positioned correctly, breathe in gently and then take the measurement on the exhale.

Take the measurement three times to make sure you get a consistent result. Holding the tape too tight so that it digs into your flesh or holding it too loosely so that it droops will cause you to get an incorrect result.

Check Your Health Risk

To find out how your waist circumference measures up, use this chart to see if your waist measurement indicates that you are at an increased risk for disease. Individual circumstances may vary, so seek the advice of a doctor to determine next steps.

If your waist measurement is greater than the numbers indicated below, your risk for weight-related health problems may be increased. For Asians, the waist circumference recommendation may need to be lower. A 2019 study done on 209 chinese men and 318 chinese women found that increased insulin resistance is observed when waist circumferences are greater than 29 inches for women and 32.5 inches for men.

How to Reduce Your Waist Measurement

If your waist circumference is in the high-risk range according to the table above, working with your doctor and a registered dietitian to lose body fat and reduce the fat in your midsection can improve your health and well-being. To get started, consider the following daily habits.

Diet

The first step to reducing your waist measurement for your overall health is to evaluate your eating habits. To get started, try observing your portion sizes and comparing your portions to the recommended serving size. If you’re not sure how much to eat, use a calorie calculator to estimate your body’s daily caloric needs. Then count calories to make sure you’re getting the right amount to fuel your body and lose weight safely.

Additionally, consider increasing the nutrient density of your diet by incorporating more nutrient-packed foods into your meal planning, including fruits, vegetables, whole grains, nuts, seeds, lean proteins, and other unprocessed foods.

Nearly a quarter of all Americans skip breakfast. Although more research is needed to solidify the importance of breakfast, a 2019 meta-analysis including eight studies and about 284,000 participants suggests that skipping breakfast increases the risk for heart disease. Skipping breakfast may also increase the risk for diabetes, becoming overweight, high blood pressure, and insulin resistance.

Eliminating sugar-sweetened beverages—soda, especially—can also cut down your sugar and calorie intake. Quitting a sugared beverage habit can offer multiple benefits, including improved sleep, increased energy, and notably, weight loss. This weight loss can then lead to a reduction in your waist measurement and disease risk.

Exercise

Once you’ve implemented a sustainable healthy eating plan, try increasing your activity level to burn more calories throughout the day and support a strong, healthy body. Again, use a calorie estimator to find out how many calories you currently burn each day, then add small habit changes to burn a few more. For example, you can take the stairs instead of the elevator at work or go for a walk every evening after dinner. Every step counts in your path to healthier living. The CDC recommends that you get 150 minutes of moderate-intense aerobic activity or 75 minutes of vigorous aerobic activity with at least 2 days of the week doing muscle-strengthening training.

Lifestyle Changes

Alongside diet and exercise, some lifestyle changes can help in reducing waist circumference and improving overall health. If you consistently get too little sleep or poor sleep, it can be even more difficult to find the motivation to make healthier choices. Improving your sleep and reducing fatigue can have a direct impact on your weight loss. The National Sleep Foundation recommends adults receive 7-9 hours of sleep per night.

Stress, like sleep, is also intricately linked to health. Research has shown that high stress can often lead to overeating, and the foods we choose while stressed tend to be high in calories and low in nutrients.

Finally, reducing alcohol consumption can also slash your calorie intake and help support weight loss. Eliminating or cutting down on these empty calories can aid in reducing your waist circumference measurement.

A Word From Verywell

There are many different ways to evaluate your health and your risk for disease—waist circumference is just one of them. If you find that yours is higher than you’d like it to be, talk to your healthcare provider about your personal health risks and get suggestions for the best ways to improve your overall health.

Often, it’s small, incremental changes to your lifestyle that ultimately make the biggest difference in your health and pave the path toward sustainable weight loss, so it’s important to begin the conversation.

How To Measure Your Waist

Whether you’re ordering clothes online, monitoring your weight, or designing a bespoke bucket chair for your space-shuttle to the moon (look, the world is on fire; it’s OK to have a plan B), you need to be able to measure your body accurately. Here’s how to get the digits for your waist.

Waist circumference measurements

Waist measurements are a bit of a life-saver when it comes to shopping for clothes. Dress sizes differ massively between the US, EU and the UK, and vague descriptors on men’s clothing aren’t much help either (S, M, L. More like FML). Checking the centimetres or inches is the most reliable thing to do to make sure your clothes fit well. If you find yourself needing to convert between cm and inches, by the way, we’ve got your back with our cm to inches converter.

In the world of healthcare, an accurate waist measurement can be used as an indicator of visceral fat, a type of body fat that’s stored within the abdominal cavity and located around vital organs such as the liver and stomach. Visceral fat has been linked to an increased risk of health complications such as heart disease, cancer and type 2 diabetes. In addition, a waist measurement can also be used as the first step towards working out your WHR (waist-to-hip ratio), another indicator of health risks. You can learn more about WHR here, and we have also included a link to the WHR calculator for you at the bottom of this article.

Before you start measuring

Find yourself a fabric tape measure (not a metal DIY one! :D) or a piece of string which you can use to mark and measure. It’s also a good idea to have a piece of paper and pen (or your smartphone) to hand, so that you can jot down the measurement (you don’t want to go to all the effort of measuring your waist and then forget the measurement). Once you have those things ready, we can start measuring.

Here’s how to measure your waist

1. Remove or lift your shirt.
2. Find the halfway point between your bottom rib and the top of your hips, just above your belly button. This is where you’ll measure your waist.
3. Slowly exhale (sucking in your tummy makes the whole exercise pointless).
4. Wrap the tape around your waist and make sure it’s level on each side, not slipping down or pulled up high and not twisted. It should be parallel to the floor.
5. Measure with the tape held snug around your skin: not too loose, but also not cutting into your skin. Take the measurement.
6. Repeat the process, just to double-check the accuracy of your original measurement.
7. Ta-da! That’s your waist measurement.

Measuring waist circumference – video

If you’re still unsure whether you’re measuring your waist circumference correctly, here’s a great video from Dr. Lara.

Waist measurement completed, here’s some ideas to consider:

1. Pat yourself on the back and buy your new jacket / dress / trousers.
2. Measure your hips in order to calculate a Waist-to-Hip measurement.
3. Interpret your waist measurement result.

Let’s take a look at number 3 together now.

Interpreting your waist measurement results

Ideally, you should look at a range of measurements before making an assessment of your personal health, and you’re recommended to consult a qualified health professional before considering radical changes to your lifestyle. With that in mind, several leading health organisations have published the following general information on waist sizes.

The World Cancer Research fund, World Health Organisation and NHS England state that your health may be at risk if your waist is*:

• Women: more than 80cm (31.5 inches)
• Men: more than 94cm (37 inches)

*Excludes those who are pregnant or have a medical condition causing a swollen abdomen. Information may vary for Asian populations. Always talk to a Doctor for medical advice.

In addition, the National Institutes of Health, U.S., states the following when assessing waist size and health risk:

If most of your fat is around your waist rather than at your hips, you’re at a higher risk for heart disease and type 2 diabetes. This risk goes up with a waist size that is greater than 35 inches for women or greater than 40 inches for men.

I do hope this article has proved useful to you. Should you wish to calculate your waist-to-hip ratio, check out our WHR calculator. Or, you can calculate your BMI here.
