About the Formulas
There are several formulas to calculate ideal body weight. Each was developed for different purposes, from clinical use to drug dosing.
The Robinson Formula
The Robinson formula (1983) is considered the most accurate for general use. It was derived from Metropolitan Life Insurance tables and refined for modern populations.
Body Frame Size
Your frame size affects ideal weight. Small-framed individuals typically weigh less than large-framed people at the same height. Measure your wrist to determine frame size.
