How the Ideal Weight Calculator Works

    More Than a Number on the Scale

    The concept of 'ideal weight' is complex and varies greatly from person to person. Instead of a single number, it's more accurate to think of a healthy weight range.

    Our calculator uses recognized formulas to provide this range, helping you set a realistic goal.

    How the Calculation is Done

    Devine Formula (1974)

    For Men

    50 kg + 2.3 kg per inch over 5 feet

    For Women

    45.5 kg + 2.3 kg per inch over 5 feet

    One of the most classic and widely used formulas.

    Robinson Formula (1983)

    For Men

    52 kg + 1.9 kg per inch over 5 feet

    For Women

    49 kg + 1.7 kg per inch over 5 feet

    An adjustment to the Devine formula, also very popular.

    Calculation Based on Ideal BMI

    Min Weight = 18.5 Γ— (Height in m)Β²
    Max Weight = 24.9 Γ— (Height in m)Β²

    This is the most modern approach, providing a range based on the healthy BMI recommended by the WHO.

    Factors that Influence Ideal Weight

    Body Composition

    Muscle is denser than fat. Athletes may have a higher ideal weight.

    Tip: Use a body fat calculator.

    Body Structure

    Bone density and frame size (small, medium, large) influence weight.

    Tip: A larger frame may mean a higher ideal weight.

    Age

    Body composition changes with age, which may alter the ideal weight.

    Tip: Focus on functionality and health, not just weight.
