What is BMI

A simple tool to help you calculate your weight category

The Body Mass Index is one of the most popular and easy to use tools to calculate your weight range. It shows the relationship between weight and height, and can help you identify a healthy weight range based on your height.

According to the Body Mass Index, people are categorised based on five classifications: underweight, healthy weight, overweight, obese and extremely obese. This can be used to determine how at risk an individual may be to health concerns as a result of their weight.


A universal measure

BMI measures are the same for both sexes

If your BMI exceeds the healthy weight range, it may increase the risks of developing conditions like diabetes, high blood cholesterol levels, high blood pressure, arthritis or sleep apnea.1

Is BMI accurate?

Although using a BMI calculator is a good way to identify whether your weight is putting your health at risk, it should be used in conjunction with other tools for a more accurate result. BMI can give a fair reflection of someone’s body fat composition because it expresses the weight-height relationship.

BMI provides a more accurate measure than body weight alone, but it does not distinguish weight which comes from fat or muscle mass. In fact, there is a strong correlation between BMI and the amount of fat that someone with more sedimentary lifestyle carries on their frame.

However, BMI does not show where the body is storing fat, research has shown that people who carry more weight around their waists are at a higher risk of health problems.

The most accurate way to assess your health risk is to use a BMI calculator alongside measuring your waist circumference and other health and lifestyle measures. A BMI calculator can be useful in helping you set your weight loss goal. Aiming to reduce your weight by 2 BMI points at a time may be a more realistic way of setting goals.

NOTE: BMI guides may not be accurate for individuals with a high muscle mass or pregnant women and may not be a good measure for children or elderly.
