Calculate your Body Mass Index

Your Body Mass Index or BMI is a general guide to reveal how healthy you are in relation to your weight and height. The BMI calculator should only be used by adults. The results do not apply to infants, small children,pregnant women or nursing mothers.

The BMI calculator is not an absolute guide and so shouldn’t be used as a medical diagnosis. The results given don’t take into consideration body shape or muscle density; ie. an athlete with a large muscle mass may get an incorrect reading.

What The BMI Results Mean

BMI 18 or Below

If your BMI is 18 or under you are underweight or bordering on being underweight. There may be an underlying reason a health check may be in order. Being underweight can be just as unhealthy as being overweight.

BMI 19 – 24

If the calculation shows between these two values, it’s considered average. Closer to 19 shows that you may become underweight sometime soon – closer to 24 shows that you may become overweight sometime soon.

BMI 25 – 29

If your result returns a figure in between these two values now is the time to seriously consider your weight and take steps to reduce your body mass. If you are over 30 years of age you may find it harder to lose weight compared to when you were younger.

BMI 30 -39

A score this high has you firmly planted in the very overweight or obese category. It is absolutely vital for your future health and for a greater life expectancy to seek a weight loss solution now.

BMI 40 +

You are dangerously or morbidly obese – medical attention should be sought sooner rather than later.
