Ideal Weight Calculator

Different researchers developed different formulas over the decades. The Devine formula (1974) was originally created for drug dosing. Robinson, Miller, and Hamwi developed their own versions based on different population studies. No single formula is universally accepted, which is why showing all four gives a more balanced range.

They are related but not identical. Ideal weight formulas give a single target number based on height and sex. Healthy weight is a range based on BMI (18.5–24.9). Most people's ideal weight falls within their healthy BMI range, but the BMI range is generally considered a more complete indicator.

Not perfectly. Athletes with high muscle mass may weigh significantly more than the ideal weight estimate while still being very healthy. These formulas are best used as a general guideline for the average adult, not for athletes or those with unusually high or low muscle mass.

The ideal weight range is a guide, not a strict target. A more useful next step is to calculate your BMI and daily calorie needs to understand where you currently stand and what adjustments — if any — might benefit your health. Always consult a healthcare professional before making significant changes to your diet or exercise habits.
