Explore →Find your healthy weight range using 5 scientific formulas
There is no single universally agreed-upon formula for ideal body weight. Different formulas were developed for different purposes over the past 50 years. The Devine formula (1974) was originally created for calculating medication dosages and remains the most widely used in clinical settings. Robinson (1983) and Miller (1983) each proposed modifications based on updated population data. Hamwi (1964) developed one of the earliest formulas, commonly used in nutrition counseling. The BMI-based range (18.5-24.9) reflects World Health Organization guidelines for healthy weight classification.
Each formula uses a different base weight and increment per inch of height, reflecting the population data and clinical purpose they were designed for. The variation between formulas typically ranges from 2-8 kg, which is normal and expected. Rather than fixating on a single number, consider the range across all formulas as your healthy target zone. Factors like muscle mass, bone structure, age, and ethnicity further influence what weight is truly optimal for your individual body.
While ideal weight calculators provide useful reference points, they have significant limitations. They cannot account for body composition โ a muscular athlete and a sedentary person of the same height may have very different ideal weights. Waist-to-hip ratio, body fat percentage, cardiovascular fitness, and metabolic health markers often provide more meaningful health information than weight alone. Use these results as a starting point for discussion with your healthcare provider, not as a definitive target.
