Ideal Weight Calculator

Healthy BMI range
57 kg–76 kg
Four formulas, one idea
Each formula anchors a base weight at 5 feet and adds per inch above it. Devine (1974) was built for drug dosing and became the clinical default; Robinson and Miller are later refinements; Hamwi is the oldest. They typically agree within a few kilograms — the spread is the honest answer.
Ideal is a range, not a number
Frame size, muscle mass, and age all shift what's healthy for an individual — the healthy-BMI weight span for your height is a better target zone than any single formula's output. Use these numbers as orientation, not prescription.
