Determining your body mass index

What is body mass index?

Determining how much you should weigh is not a simple matter of looking at a height-weight chart, but includes considering the amount of bone, muscle and fat in your body's composition.

The amount of fat is the critical measurement. A good indicator of how much fat you carry is the body mass index (BMI). Although it is not a perfect measure, it gives a fairly accurate assessment of how much of your body is composed of fat.

How can I tell if I'm overweight?

Use the tool on this page to calculate your BMI. Having a BMI higher than 24.9 may mean you are overweight. Note that these are approximate values, and they are intended to be used only as a rough guide.

If you are worried about your BMI or are trying to lose weight, talk to your primary care doctor. You may also wish to contact the Rush Center for Weight Loss and Lifestyle Medicine, which offers individualized weight loss and wellness programs for people of all ages. You may also contact the Rush Nutrition and Wellness Center or the Rush University Prevention Center. These programs offer nutrition counseling and help with making lifestyle changes.

Doctors at Rush offer bariatric surgery for some people who are morbidly obese (those with a BMI of at least 40, or a BMI of at least 35 plus an obesity-related disease such as diabetes or high blood pressure).

What should my bmi be for my height

This calculator should only be used by adults (pregnant or lactating women should not rely on these BMI readings), and no action should be taken based on its values other than to consult a suitably qualified person such as a doctor.

The calculator will give you an idea of how your weight compares to common values. Body Mass Index (or BMI) is calculated as your weight (in kilograms) divided by the square of your height (in metres) or BMI = Kg/M2.

Is Body Mass Index reliable?

Your BMI, or Body Mass Index, is a measure of your weight compared to your height. Accurate assessments of obesity are important, as being overweight or obese significantly increases your risk of a variety of medical conditions including type 2 diabetes, heart disease and cancer. As levels of overweight or obesity increase, the spotlight has fallen on BMI and its shortcomings as a measure of ideal weight for individuals, rather than whole populations of people where 'averages' apply.

"Some people naturally have a larger frame than others. But this causes quite a small variation in weight and is accounted for in the range of healthy BMI. There is really no such thing as someone who is big-boned." Dr Jan Sambrook, How to lose weight in a healthy way

For most adults, BMI gives a good estimate of your weight-related health risks. If your BMI is over 35, your weight is definitely putting your health at risk, regardless of the factors below. However, there are some situations where BMI may underestimate or overestimate these risks in the 25-35 BMI range. The main ones are:

Children

Your GP or health visitor can advise on where your child sits on the ‘centile charts’ used to estimate healthy weights for children.

Pregnant women

Usual BMI estimates do not apply if you’re pregnant.

If you are very muscular

BMI assumes you have an average amount of body fat, including ‘intra-abdominal fat’ – fat deep inside your stomach cavity rather than under your skin. Intra-abdominal fat is much more closely linked to risks of type 2 diabetes and heart disease than fat under the skin.

If you are very muscular, your level of body fat may be lower than predicted by your BMI. However, this only applies to people who do high levels of exercise – much more than average.

If you are of Asian origin

People of Asian origin are prone to accumulating intra-abdominal fat (fat deep inside your stomach cavity rather than under your skin) at a lower BMI than people of Caucasian origin. People with this pattern of weight gain are described as ‘apples’ rather than ‘pears’ from their body outline. This means their health risks start to rise at a lower BMI, because intra-abdominal fat is directly linked to development of heart disease and type 2 diabetes.

The World Health Organisation has looked at the evidence and because of the variability between different Asian populations, it hasn't officially changed the cut-off points. However, it does recommend that for public health purposes, some Asian groups should be considered overweight if their BMI is 22-25, and obese with a BMI of 26-31.

Older people (over 65, possibly over 60)

Because muscle mass tends to drop and body fat tends to rise in older people, BMI may not be an accurate reflector of body fat if you're over 60.

If you feel BMI may not accurately reflect whether you are overweight or obese, measuring your abdominal circumference, waist-hip or waist-height ratio may give you a more realistic estimate.

Waist circumference

You measure your waist circumference half way between the bottom of your ribcage and the top of your hip bones, with the tape measure parallel to the floor. You must be breathing out when you measure. 

Male

  • Increased health risk - ≥94cm                                   
  • High health risk - ≥102cm

Female

  • Increased health risk - ≥80cm
  • High health risk - ≥88cm

Waist to hip ratio

To check your waist to hip ratio, measure your waist circumference (as above), and your hip size at the widest part of your hips. Divide your abdominal circumference by your hip measurement to give a ratio.

  • In women, a waist to hip ratio greater than 0.85 is associated with greater than average risk.
  • In men, a waist to hip ratio greater than 1.00 is associated with greater than average risk.

Waist to height ratio

A recent study comparing BMI, waist circumference, waist to hip ratio and waist to height ratio found that the most accurate way of predicting your whole-body fat level was waist-height ratio.

Measure your waist circumference as above and simply divide it by your height – fairly obviously both measurements should either be in imperial (inches) or metric (cm).

Whole body obesity is defined by a waist-height ratio of:

  • 0.53 or more for men
  • 0.54 or more for women

Abdominal obesity was defined by a waist-height ratio of 0.59 or more.

What is the correct BMI for my height?

A BMI of less than 18.5 means a person is underweight. A BMI of between 18.5 and 24.9 is ideal. A BMI of between 25 and 29.9 is overweight. A BMI over 30 indicates obesity.

What BMI should I have for my age?

Doctors recommend most adults keep their BMI between 18 and 24.9. Adults with a BMI over 25 are considered obese. On the other hand, older adults do better if they have a BMI between 25 and 27. Research shows that adults over 65 who are underweight experience more health issues and shorter life expectancy.

Is BMI weight for height?

Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.
