A healthy weight range is defined as a BMI between 18.5 and 24.9. This range is associated with the lowest risk of weight-related health complications, according to World Health Organization guidelines. This calculator tells you the specific weight range that corresponds to that BMI window for your height.
The healthy weight range for a 5-foot-6-inch person spans from about 115 to 154 lbs. That is a 39-pound range, which illustrates that "healthy weight" is not a single number but a meaningful range that accommodates significant natural variation in body type and composition.
The healthy weight ranges in this calculator are based on BMI, which is a useful population-level screening tool but has recognized limitations. It does not distinguish between muscle and fat mass, does not account for where fat is distributed, and may not apply equally across all ethnic backgrounds. Research suggests that South Asian and East Asian populations may have elevated health risks at BMI levels that are classified as normal using Western-derived thresholds.
Overall health encompasses much more than body weight. Blood pressure, blood sugar, cholesterol, cardiovascular fitness, sleep quality, and mental health are all meaningful indicators of health that BMI does not capture. Someone at the upper edge of the normal BMI range who exercises regularly, eats well, does not smoke, and sleeps adequately may be in excellent health, while someone in the middle of the normal range who is sedentary and under chronic stress may not be.
