An adult female who is 5 feet 5 inches tall ideally weighs between 114 and 150 pounds. This puts her body mass index in the recommended range of 18.5 to 24.5. However, individuals with different body types have different ideal weights. Doctors consider those circumstances before setting a target weight.
BMI is a measurement that determines whether a person's weight falls into a healthy range for her height and sex. Individuals who have a BMI lower then 18.5 are underweight, while those with a BMI over 24.5 are considered clinically overweight. A BMI greater than 30 is classified as obese.
