BMI and Weight
The Body Mass Index (BMI) provides a reasonably accurate measurement of weight for the majority of Americans. A 5-foot-7-inch person should weigh between 121 and 159 lbs., according to the BMI chart provided on the National Heart, Blood and Lung Institute website.
Other Measurements to Consider
Measurements such as body fat percentage, waist measurement and fitness tests prove invaluable in assessing a person's health. Such tools offer important additional information regarding a person's overall physical health and unique body composition.
Use BMI as a tool to assess weight in addition to other useful measurements to provide a full picture of physical health. Consult your physician regarding any concerns or questions and before beginning any weight loss program.
