Ideal Body Weight Calculator

Calculate your ideal body weight using 4 proven clinical formulas: Devine, Robinson, Miller, and Hamwi. Find your healthy weight range based on height and gender.

How to Use & Understand This Calculator

No single formula perfectly defines an "ideal" weight for every person, which is why this calculator provides four different clinically developed estimates simultaneously. Comparing multiple results gives you a more balanced range to aim for.

The Devine Formula (1974) was originally developed for calculating drug dosages in clinical pharmacology. It became widely adopted as a general IBW (Ideal Body Weight) reference. Robinson Formula (1983) was refined to better suit modern populations. Miller Formula (1983) tends to produce slightly higher values. Hamwi Formula (1964) is still widely used in dietetics.

All formulas share the same basic structure: a base weight at 5 feet (60 inches) plus an increment for each inch above that. For heights below 5 feet, the formulas become less reliable. For taller individuals, all formulas tend to underestimate healthy weight for very muscular frames.

Use these numbers as a rough guide, not a strict target. Body composition (muscle vs. fat), bone density, age, and ethnicity all affect what "ideal" really means for your unique body. Consult a doctor or registered dietitian for personalized guidance.
