Body Mass Index (BMI) Calculator

Your BMI tells you if you're a healthy weight for your height. However, this is general advice for adults only. It does not apply to children, pregnant women or women who are breastfeeding.

Also, your BMI may not be accurate if you:

  • are a weight-trainer or an athlete,
  • are over the age of 60, or
  • have a long-term health condition.

Speak with your GP if you have noticeably lost or gained weight recently for no known reason.
