This calculator uses the Devine formula, one of the most widely used ideal body weight formulas: for men, Ideal Weight (kg) = 50 + 2.3 × (height in inches − 60). For women, the same formula is used but starting from 45.5 kg instead of 50.
The formula is based on height over 5 feet (60 inches), adding 2.3 kg for every inch above that baseline.
For example, for a man 178 cm tall: first convert to inches, 178 ÷ 2.54 = 70.08 inches. Subtract the 60-inch (5 ft) baseline: 70.08 − 60 = 10.08 inches over. Multiply by 2.3: 10.08 × 2.3 = 23.18. Add the 50 kg base: 50 + 23.18 = 73.2 kg (about 161.3 lb).
This formula was originally developed for medical dosing calculations and provides only a general reference point. It doesn't account for muscle mass, bone structure, or individual body composition, so it shouldn't be treated as a strict personal weight goal.
Treating the Devine formula's result as a strict target weight, it was originally built for medication dosing, not as a personal fitness or aesthetic goal.
Ignoring frame size and muscle mass entirely, someone with a larger bone structure or more muscle mass will naturally sit above this estimate without being overweight.
Using it as the sole measure of healthy weight instead of pairing it with BMI, body fat percentage, or a healthcare provider's assessment for a fuller picture.
It's a general estimate widely used in medical settings, but it doesn't account for muscle mass, frame size, or individual body composition, so actual healthy weight can vary from this estimate.
The formula uses different baseline constants for men and women to reflect typical differences in body composition, this is a simplification, not a precise individual assessment.
