Body Mass Index (BMI) Calculator
The healthy weight range is based on a measurement known as the body mass index (BMI). This can be determined if you know your weight and your height.
Frame sizes vary and it is difficult for any simple measurement to establish a person's frame. It is more accurate to recommend a weight range, rather than a specific weight for a given height.
Here, we've made it easy for you. To calculate your BMI simply select your correct height and weight and let the BMI calculator do the rest.
Remember that weight is also related to build, and you should make allowances if you are stocky or of heavy build. Your BMI will vary slightly according to gender.
Your Body Mass Index (BMI) is:
People with BMI's of 25 to 29.9 are considered overweight, while those with BMI's of 30 and above are considered obese. Those with BMI's of 18.5 or less are considered underweight.
Please note that the BMI ranges were calculated using averages. If any of the following circumstances apply, you may be provided with an inaccurate reading:
You are under 18 years of age
You are pregnant or breastfeeding
You are a competitive athlete or a body builder
You are convalescent or elderly
