Body Mass Index
Body mass index, BMI, is a number generated by dividing your weight in kilograms by your height in metres squared.
Body mass index (BMI) = weight(kg) / height(m)2
Don't worry, you don't have to work it out for yourself, take a free trial on Weight Loss Resources and the computer will calculate it for you!
Our ideal weight range charts are based on body mass index, modified to take into account whether you are male or female.
For adults, BMI is a guide to measuring whether you're a healthy weight for your height. Note that it is not so accurate for muscled athletes, or very frail people. Nor is it a suitable guide for women who are pregnant or breastfeeding.
