BMI Calculator

Body mass index, or BMI, is used to determine whether you are in a healthy weight range for your height.

It is useful to consider BMI alongside waist circumference, as waist measurement helps to assess risk by measuring the amount of fat carried around your middle.

What's BMI?

BMI compares your weight to your height, and is calculated by dividing your weight (in kilograms) by your height (in metres squared). It gives you an idea of whether you’re 'underweight', a 'healthy' weight, 'overweight', or 'obese' for your height. BMI is one type of tool to help health professionals assess the risk for chronic disease. Another important tool is waist circumference.

You are underweight for your height. It's important to aim to keep within your healthy weight range. Being in the healthy weight range will improve your body's ability to fight off infection or illness.

But we recommend that you also check your waist measurement.

Waist measurement

Waist circumference is a simple check to tell if you are carrying excess body fat around your middle.

Where your fat is on your body can be an important sign of your risk of developing ongoing health problems. Carrying excess body fat around your middle is more of a health risk than if weight is on your hips and thighs.

Regardless of your height or build, for most adults a waist measurement of greater than 94 cm for men and 80 cm for women is an indicator of the level of internal fat deposits which coat the heart, kidneys, liver, digestive organs and pancreas. This can increase the risk of heart disease and stroke.

Waist measurement helps to assess risk by measuring the amount of fat carried around your middle. It can be used along with measuring your body mass index (BMI). Together, these tools give an indication of your risk linked with excess body fat.

Check your waist measurement below, and if you think you’re at risk, talk to your doctor or dietitian about what you can do.

How to measure your waist

  1. Find the top of your hip bone and the bottom of your ribs.
  2. Breathe out normally.
  3. Place the tape measure midway between these points and wrap it around your waist.
  4. Check your measurement.

Measurements

For men, your health is at risk if your waist size is over 94cm. For women, your health is at risk if your waist size is over 80cm.

These guidelines are based on World Health Organization and National Health and Medical Research Council recommendations.

Who the measurements apply to

Waist circumference is less accurate in some situations, including pregnancy, medical conditions where there is distension of the abdomen, and for certain groups such as Aboriginal and Torres Strait Islander peoples, South Asian, Chinese and Japanese adults. Talk to your doctor for more information.

Waist measurements should only be used for adults to check their risk of developing a chronic disease.

You are a healthy weight for your height. But we recommend that you also check your waist measurement.

Aim to keep within the healthy weight range by enjoying a healthy, well-balanced diet and exercising regularly. Most adults should get at least 30 minutes of moderate-intensity physical activity on most, if not all, days.

For older Australians, your general health may be more important than being mildly overweight. Some researchers have suggested that a BMI range of 22-26 is acceptable for older Australians over 70 years old.

Being overweight increases your risk of developing coronary heart disease, as well as other health conditions. Keeping to a healthy weight will help you control your blood pressure and cholesterol levels. To achieve and maintain a healthy weight, be physically active every day and enjoy a healthy, well-balanced diet.
