# Ideal Weight Calculator See your estimated ideal body weight from four classic formulas — Devine, Robinson, Miller and Hamwi — based on height and sex. Runs entirely in your browser. | Formula | Ideal weight | | --- | --- | | Devine | 75 kg · 165.3 lb | | Robinson | 72.6 kg · 160.2 lb | | Miller | 71.5 kg · 157.7 lb | | Hamwi | 77.3 kg · 170.5 lb | Population averages from height alone — they ignore build, muscle and frame. Not medical advice. ### How it works Each formula starts from a base weight at 5 feet (60 inches) and adds a fixed amount per inch above that — for example **Devine** uses 50 kg + 2.3 kg/inch for men (45.5 + 2.3 for women). Robinson, Miller and Hamwi differ only in those constants, which is why they give a small range rather than one number. Height is converted to inches first; all maths runs locally. --- *Source: [ocxly.com/ideal-weight-calculator.html](https://ocxly.com/ideal-weight-calculator.html) — OCXLY, free 100% client-side privacy-first tools.
