Weights calculated from BMI 18.5 (lower bound) and 24.9 (upper bound) for each height.

The range is derived from Body Mass Index (BMI). The World Health Organisation defines a healthy BMI as 18.5–24.9 for adults. To find the healthy weight range for a given height:
Example for 175 cm (1.75 m): 18.5 × 1.75² = 56.6 kg and 24.9 × 1.75² = 76.2 kg.
BMI does not account for muscle mass. A muscular athlete may have a BMI in the "overweight" range with no excess body fat. It also does not distinguish where fat is stored — abdominal fat carries higher health risks than fat distributed elsewhere. Use BMI as a general reference, not a definitive health verdict.
For a height of 5 feet 11 inches (180.3 cm), the healthy weight range based on BMI 18.5–24.9 is approximately 60.1–81.0 kg (132.5–178.6 lbs). This means a weight below 60 kg at that height is considered underweight, and above 81 kg is considered overweight by BMI standards. Use the calculator above to check any height.
For 5 feet 6 inches (167.6 cm), the healthy BMI range corresponds to approximately 52.0–70.0 kg (114.6–154.3 lbs). The exact midpoint of this range — around 61 kg (134 lbs) — represents a BMI of approximately 21.7, which is solidly in the middle of the normal range.
The formula: weight (kg) = BMI × height (m)². For the healthy range, use BMI 18.5 for the minimum and 24.9 for the maximum. For a 175 cm person (1.75 m): 18.5 × 1.75² = 56.6 kg (minimum) and 24.9 × 1.75² = 76.2 kg (maximum). The same formula works in any units — just convert height to metres first.
BMI is a useful population-level screening tool but has known limitations. It does not account for muscle mass — a muscular person may have a high BMI with little body fat. It also does not consider fat distribution; abdominal fat is more closely linked to cardiovascular risk than fat stored elsewhere. BMI is most reliable for people with average body composition and less reliable for athletes, older adults, and people of certain ethnic backgrounds where the healthy range thresholds may differ.
