Compare ideal body weight across the Robinson, Miller, Devine and Hamwi formulas.
The Devine formula gives a single reference weight based on height and sex, while the BMI-based range shows the span of weights considered healthy for your height (BMI 18.5–24.9).
Devine formula — Male
IBW (kg) = 50 + 2.3 × (height in inches − 60)
Devine formula — Female
IBW (kg) = 45.5 + 2.3 × (height in inches − 60)
Healthy BMI range
Healthy weight range = BMI × height (m)² for BMI 18.5 to 24.9
This is an estimate and not medical advice. Ideal weight varies with individual body composition, age, and health conditions. Consult a healthcare professional for personalised guidance.
Treat the BMI range as your healthy target zone; the Devine figure is one point of reference within it. Individual ideal weight depends on muscle, frame, and health factors.
No. Healthy weight is a range, and factors like muscle mass and body composition matter more than a single target.
