What Is a Ideal Weight Calculator?

An ideal weight calculator estimates a healthy target body weight from height alone using published clinical formulas. We compute Devine (1974), Robinson (1983), Miller (1983) and Hamwi (1964) — each used historically in dosing, insurance tables and nutrition screening. Results are shown per formula plus a combined min–max range and mean.

Ideal weight ranges help set realistic goals alongside BMI and body composition. Multiple formulas highlight that “ideal” is not a single number — comparing them gives a band rather than false precision.
