Ideal Weight Calculator

Four classic ideal-weight formulas, side by side — so you can see the range rather than chase a single number.

There's no single right answer

Each formula gives a slightly different number because they were developed for different populations and purposes (medication dosing, military fitness, life-insurance tables). Use the range, not the average.

These are population-average formulas from the 1970s-80s — none account for muscle mass or frame size directly, so treat the range as a rough guide rather than a target to hit exactly.
