BMI weight ranges for adults:

Weight that is higher than what is considered as a healthy weight for a given height is described as overweight or obese. Weight that is lower than what is considered as healthy for a given height is described as underweight.

• If your BMI is less than 18.5, it falls within the underweight range.
• If your BMI is 18.5 to 24.9, it falls within the Healthy Weight range.
• If your BMI is 25.0 to 29.9, it falls within the overweight range.
• If your BMI is 30.0 or higher, it falls within the obese range.

Consider that BMI can be used as a screening tool but not diagnostic of the body fatness or health of an individual. A trained healthcare provider should perform appropriate health assessments in order to evaluate an individual’s health status and risks.

Weight that is higher than what is considered as a healthy weight for a given height is described as overweight or obese. Weight that is lower than what is considered as healthy for a given height is described as underweight.

Limitations of the BMI

Muscle mass

The BMI calculation does not include muscle mass, which weighs more than fat.

This means muscular adults and athletes may be classed as overweight or obese even though their body fat is low.

How the BMI is calculated

The BMI calculation divides an adult’s weight in kilograms (kg) by their height in meters (m) squared.

Example: if you weigh 70kg and are 1.73m tall, you work out your BMI by:

1. squaring your height: 1.73×1.73 = 2.99
2. dividing 70 by 2.99 = 23.41

Your result will be displayed to 1 decimal place, for example 23.4.

Waist to height ratio

Measuring your waist to height ratio can tell you if you have excess tummy fat, even if you have a healthy BMI.

To calculate your waist to height ratio, measure your waist and divide it by your height. Use measurements in the same units (for example, centimeters or inches).

A waist to height ratio of 0.5 or higher means you may have increased health risks such as heart disease, type 2 diabetes and stroke.
