How Much Should a 5-Foot-5-Inch Woman Weigh?

Using the Formula

According to body mass index (BMI) calculations, a woman that stands 5 feet 5 inches should weigh roughly between 120 and 150 lbs. This method determines the BMI by multiplying a person’s weight in pounds multiplied by 703 and then divided by the person's height in inches squared.

Factor in the Variables

The BMI system, first used in the late 18th century, is antiquated. This method does not take several important factors into consideration when making the calculations. The original BMI does not factor in age, gender or frame size when making the calculations.

Bottom Line

When it comes to matters of health, you should always confer with your family doctor to see if your weight is appropriate for your size. Some insurance companies still use BMI when determining health risks for insurance policies even though debate exists about its relevance 1.
