About ideal weight
There’s no single “perfect” weight — a healthy weight is a range, not a number. This tool shows the weight range that corresponds to a healthy BMI for your height, plus a classic single-figure estimate for reference. Use it as a guide, not a strict rule.

Frequently asked questions
How is the healthy range worked out?
The healthy range is the weight that gives a BMI between 18.5 and 24.9 for your height — the range generally considered healthy for adults.
What is the “ideal weight” figure?
It uses the Devine formula, a classic medical estimate. Treat it as a single reference point within the healthy range, not an exact target.
Why does sex matter?
The Devine ideal-weight formula uses slightly different baselines for men and women.
