Body Mass Index is used to estimate your total amount of fat. It is only an approximate measure of the best weight for your health.
This calculator is designed for men and women over the age of 18.
A healthy BMI for an adult is between 20 and 25.
What your BMI means
Once you have measured your BMI, you can determine your healthy weight range. If your BMI is:
- Under 18.5 - you are very underweight and possibly malnourished.
- 18.5 to 24.9 - you have a healthy weight range for young and middle-aged adults.
- 25.0 to 29.9 - you are overweight
- Over 30 - you are obese.
