Another way to go about this is to use the general rule of weight. For adults, a person should weigh 100 pounds for the first five feet of their height and then add 5 pounds for every inch above it. For example, if I am five feet 3 inches tall, I should weigh 115 pounds (100+5+5+5). People with a medium frame may use the same value. People with a small frame need to subtract 5% from this value and people with a large frame need to add 5%.
A more accurate way is to use the Body Mass Index (BMI). It uses your height and current weight and tells you where you stand. So that, rather than just knowing how much you should weigh, it also tells you how far you are from your ideal weight.
The general formula used to calculate BMI is:
BMI (kg/m2) = Weight in pounds x 703
height in inches2
