Calculate BMI

Your Body Mass Index (BMI) is:

People with a BMI of 25-29.9 are considered overweight, while people with a BMI of over 30 are categorised as obese.

If your BMI is under 18.5, you are considered underweight.

Factors to note when calculating your BMI

Remember, weight is also related to build, so you should make allowances if you are stocky or of heavy build. Your BMI will also vary slightly according to your gender.

It’s also important to note that BMI ranges are calculated using averages. Your reading may be inaccurate if you are:

  • Under 18
  • Pregnant or breastfeeding
  • A competitive athlete or a body builder
  • Convalescent or elderly

If you are unsure of your BMI, visit a doctor or registered nutritionist for more detailed information.
