BMI Calculator

You can use the Body Mass Index calculator to find out if you’re a healthy weight for your height
  • If your BMI is less than 18.4 you are underweight for your height.
  • If your BMI is between 18.5 and 24.9 you're an ideal weight for your height.
  • If your BMI is between 25 and 29.9 you’re over the ideal weight for your height.
  • If your BMI is between 30 and 39.9 you're obese.
  • If your BMI is over 40 you're very obese.

This is general advice for adults only; it does not apply to children, pregnant women, older people or anyone with a long-term health condition. If you’re a weight-trainer or an athlete this BMI may not be accurate
