⚖️ Ideal Weight Calculator
Find your ideal body weight range for your height using the Devine and Robinson formulas plus the healthy BMI range.
About this Ideal Weight Calculator
Ideal Weight Calculator combines the two classic medical formulas — Devine and Robinson — which estimate weight from height above 5 feet, with the World Health Organization healthy BMI band for your height. Seeing all three together gives a sensible target range instead of one fragile number.
How to use it
- Enter your height in centimetres.
- Select your gender (the formulas use different base values).
- Press Calculate ideal weight.
- Compare the formula values with the healthy BMI band for a realistic goal.
Example
A 170 cm man gets a Devine value of about 65.9 kg, a Robinson value of about 65.2 kg, and a healthy BMI range of 53.5–72.0 kg.
Frequently asked questions
Why do the formulas disagree slightly?
They were fitted to different population studies in different decades. Treat them as guides that should roughly agree, not exact prescriptions.
I am muscular — is the BMI range wrong for me?
BMI cannot tell muscle from fat, so very muscular people may sit above the band while staying healthy. A body-fat check gives a fuller picture.
