Ideal Weight Calculator
See ideal-weight estimates from several classic formulas, and why they're only a rough guide.
A range, from a few formulas
Ideal body weight formulas estimate a target weight mainly from height, and there are several classic ones that give slightly different figures. This shows estimates from those formulas, so you can see the range rather than a single number, along with an honest sense of their limits.

Why 'ideal weight' is a loaded idea
These formulas are worth treating with real caution. They were mostly derived decades ago from limited populations and are based almost entirely on height, so they ignore body composition, frame size, muscle mass and the huge natural variation between healthy people — a muscular person can sit well above an ideal-weight figure while being perfectly healthy. There is no single correct weight for a given height, and health is far more than a number on a scale. Treat these as a rough historical reference, not a target to chase. This is general information, not medical advice, and a healthy weight for you is best discussed with a qualified professional who can consider the whole picture.
Frequently asked questions
Why do the formulas give different numbers?
They were derived from different populations and assumptions decades ago, so each gives a slightly different estimate from height alone.
Is there one ideal weight for my height?
No — these formulas ignore body composition, frame and muscle, and there is wide natural variation between healthy people. Treat them as a rough reference only.
Is this medical advice?
No — it is general information. A healthy weight for you is best discussed with a qualified professional who can consider the whole picture.
