What is Ideal Weight?

The Ideal Weight Calculator provides a healthy weight range based on your height and gender using several well-known formulas, including the Devine, Robinson, and Miller formulas. These formulas were originally developed for medical purposes—particularly to estimate drug dosages—but have since become widely used as general guidelines for healthy body weight. The calculator aggregates results from multiple formulas to give you a range rather than a single number, acknowledging that "ideal" weight varies by body type and composition.

It is important to understand that ideal body weight is not a perfect measure of health. The formulas consider only height and gender; they do not account for muscle mass, bone density, body frame size, or activity level. A muscular athlete may fall above the "ideal" range while being in excellent health, whereas someone within the range might still have elevated body fat. Think of these results as a reference range, not a strict target you must achieve.

No single metric can definitively state how much a person should weigh. The ideal weight range is most useful when considered alongside other measures such as BMI and body fat percentage. Focus on sustainable healthy habits—regular exercise, a varied diet, adequate sleep—rather than chasing a specific number on the scale.
