Ideal Weight Calculator
Result Summary
Athletes and individuals with high muscle mass may healthily exceed these ranges. Consult a physician for a personalized target.
Clinical Weight Targeting & Physiological Optimization
In clinical nutrition and pharmacological dosing, determining a patient's ideal body weight is crucial for ensuring the safe administration of medications and plotting long-term health trajectories. Unlike Body Mass Index (BMI), which offers a broad categorical range based on population averages, an ideal weight calculator utilizes established physiological algorithms to pinpoint a specific, actionable weight target based on a person's exact height and biological sex.
Our tool cross-references the three most scientifically validated formulas: Devine, Robinson, and Miller. The Devine formula serves as our primary anchor, as it remains the undisputed gold standard in medical environments globally. It calculates a basal weight for a base height (5 feet) and scales mathematically for every additional inch, providing a highly reliable benchmark for individuals looking to set precise fitness and dietary goals.
The Science Behind the Primary Formulas
- The Devine Algorithm (1974): Originally developed to calculate precise pharmacokinetics (specifically the clearance of drugs like gentamicin). It is the most universally accepted metric for establishing a baseline "healthy" weight.
- The Robinson Algorithm (1983): Created as an adjustment to the Devine method. It typically suggests a slightly heavier baseline for both men and women, compensating for changes in modern bone density and average body composition.
- The 10% Healthy Variance Zone: Medical science acknowledges that human anatomy is heavily influenced by genetics, bone structure (frame size), and muscle mass. Therefore, any ideal weight calculation serves as the exact midpoint of a healthy range. Our tool automatically calculates a safe ±10% buffer around this target, ensuring your goals remain realistic and physiologically sound.
How to use
- Select your biological gender, as male and female physiological algorithms differ significantly in baseline mass.
- Enter your height in centimeters. The system will instantly convert this to feet and inches for algorithmic processing.
- Review your primary target weight generated by the Devine formula in the results panel.
- Compare this target against the Robinson and Miller formulas in the comparison table.
- Aim for the 'Healthy Range' (±10%), rather than fixating strictly on the absolute numerical target.

Healthy Weight Range Guide
An ideal weight range is a benchmark for long-term health and stability. This calculator helps you determine a target weight that minimizes the risk of metabolic and cardiovascular issues. Many users also utilize this solar estimator alongside this analysis.
