Ideal Weight Calculator

How ideal weight is calculated

There is no single "ideal weight" — it depends on your body composition, bone structure, muscle mass, and overall health. This calculator uses five well-known formulas to give you a range of estimates. The Devine, Robinson, Miller, and Hamwi formulas were developed for clinical use and are based on height and sex. The BMI-based estimate uses the midpoint of the healthy BMI range (21.75). The average of all five gives you a reasonable target, but remember that individual factors like muscle mass and body frame can shift your personal ideal.

What your result means

The result is a general guideline, not a strict target. A person with more muscle mass may weigh more than the "ideal" without being overweight. Similarly, someone with a smaller frame may be healthy at a lower weight. Use the range from the different formulas as a reference band rather than fixating on a single number. If you are significantly above or below the range, consult a healthcare professional for personalized guidance.
