Waist circumference is a measurement taken around the abdomen at the level of the umbilicus (belly button). Health experts use waist circumference to screen patients for possible weight-related health problems.

Why Waist Circumference Matters

Measuring the size of your waist can help you to understand your risk for certain health conditions that are related to your weight. Waist circumference alone cannot indicate that you have a medical condition or that you'll get one in the future.

But it can help you and your health care provider to determine where fat is located on your body and if that fat may cause health problems for you in the future.

According to the National Institutes of Health, 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 also use your waist measurement to calculate your waist-hip ratio (WHR). Waist-hip ratio provides another screening tool for weight-related disease risk.

How to Measure Waist Circumference

To measure waist circumference correctly, you should use a flexible tape measure that is not elastic. The tape measure should not stretch when you are taking your belly measurement. You should also remove any bulky clothing that can add padding at the abdomen.

Stand up to get an accurate waist measurement. Then, wrap the tape measure around the widest part of your stomach, across your belly button.

The tape measure should rest gently on your skin. Once the tape measure is positioned correctly, breathe in gently and then take the measurement on the exhale.

Is  My Waist Circumference Normal?

So how does your waist circumference measure up? Use this chart to see if your risk for disease is higher than normal.

 If your waist measurement is greater than the numbers indicated, your risk for weight-related health problems is higher than normal.
