What is the 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.
Why people use this calculator
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.
