Ideal Weight Calculator estimates ideal body weight using four peer-reviewed formulas (Robinson, Miller, Devine, Hamwi) and shows a healthy BMI weight range for your height.
Ideal Weight Calculator is a high-performance utility designed to help users streamline their workflow. Built with modern web technologies, it ensures fast processing times and high-quality outputs directly in your browser.
Robinson (1983): men = 52 + 1.9×(inches over 5 ft); women = 49 + 1.7×. Miller (1983): men = 56.2 + 1.41×; women = 53.1 + 1.36×. Devine (1974): men = 50 + 2.3×; women = 45.5 + 2.3×. Hamwi (1964): men = 48 + 2.7×; women = 45.4 + 2.3×. Healthy BMI range (18.5–24.9) is calculated from height. These are statistical population references, not clinical prescriptions.
No single formula is universally most accurate — all were developed before modern body composition analysis. The Robinson (1983) formula is most commonly cited in medical literature. Use the healthy BMI range (18.5–24.9) for a science-backed reference.
Not exactly. 'Ideal weight' formulas estimate a single target number while 'healthy weight' covers a range (BMI 18.5–24.9). Muscle mass, bone density, and body composition are not factored in — a muscular athlete may be 'overweight' by these formulas yet perfectly healthy.
Developed in 1974 by Dr. B.J. Devine, originally for calculating drug dosages: Males: 50 + 2.3 kg per inch over 5 feet; Females: 45.5 + 2.3 kg per inch over 5 feet. It's still used clinically for medication dosing.
A loss rate of 0.5–1 lb/week is considered safe and sustainable. Combine a moderate calorie deficit (~500 kcal/day) with adequate protein (0.7–1g/lb) and resistance training to preserve muscle while losing fat.
