Ideal Weight Calculator
Estimate a healthy weight range for your height using established formulas.
There's no single "ideal" weight — which is exactly why it helps to see several respected estimates side by side rather than one arbitrary number. Clinical formulas like Devine and Robinson give a target based on height and sex, while a healthy BMI range (18.5–24.9) gives a band rather than a point. Together they sketch a realistic healthy range instead of a single unforgiving target.
Enter your height and sex and this calculator shows the ideal weight from the classic Devine and Robinson formulas, plus the weight range corresponding to a healthy BMI. Treat these as guides, not rules — they don't account for muscle mass, frame size or individual health.
