Weight Range for Adults
The Body Mass Index (BMI) sets the target healthy weight for adults 5 feet 3 inches tall from 107 to 140 lb. People weighing from 141 to 168 lb. fall into the overweight category, while those weighing 169 lb. and up are considered obese.
Weight Range for Children and Teen-agers
It is likely that the bodies of people under 20 years old are still growing and changing. These younger individuals' target healthy weight range may differ from the range for adults especially for those in their early teens. The BMI calculator for children and teen-agers, which is linked in the Resources section, bases weight ranges on age, gender, height and weight.
The healthy weight range for someone who is 5 feet 3 inches tall depends on the person's age. The U.S. Department of Health and Human Services website states that a 500-calorie or more reduction per day is common for people trying to lose weight and that more than 60 minutes of exercise per day is advised for formerly overweight people to maintain weight loss.
