BMI Calculator

Body Mass Index (BMI) is a numerical measurement derived from an individual’s height and weight, providing an indication of body size. As a reliable health assessment tool, BMI helps categorise individuals into different weight status categories, such as underweight, normal weight, overweight, and obesity.

The below BMI calculator utilises this formula to offer a quick and easy way to assess your body weight relative to your height.


BMI Classifications are:

  1. Underweight:
    • BMI less than 18.5
  2. Normal weight:
    • BMI between 18.5 and 24.9
  3. Overweight:
    • BMI between 25 and 29.9
  4. Obesity:
    • BMI of 30 or greater

Remember that while BMI is a useful screening tool, it doesn’t directly measure body fat percentage or health, and individual circumstances should be considered for a comprehensive health assessment.
