Ideal weight formulas are estimates and don’t account for frame size or muscle mass. Use as a rough reference only.
What it does
A free ideal weight calculator using the four standard formulas — Devine, Robinson, Miller, and Hamwi — so you can compare across them. Enter sex and height; get estimates in kg and lb.
Ideal weight formulas are rough guidelines. They don’t account for frame size, muscle mass, or body composition, so athletes often fall outside the range despite being in excellent health. Treat these as one reference point among several.
How to use it
- Pick your sex.
- Enter your height in cm.
- Compare results across the four formulas.
- Use as rough reference, not as a strict target.
