Estimate a healthy weight range for your height. This calculator shows the four most-cited formulas alongside the healthy weight range from BMI 18.5 to 25. Treat the result as a guide, not a personal target - and everything is calculated privately in your browser.

These are estimates from population formulas, not a personal target. They do not account for build, muscle, or body composition, and the healthy BMI range is often more useful. For personal advice, speak with a healthcare provider.
"Ideal body weight" formulas were originally developed for medical dosing, not as personal goals. The classic four - Robinson, Miller, Devine, and Hamwi - each start from a base weight at 5 feet of height and add a fixed amount per inch above that, with different numbers for men and women. They typically disagree by a few kilograms, which is why we show a range.
None of them accounts for build, muscle, or body composition, so a very muscular person can sit above these estimates while being perfectly healthy. For most people the healthy weight range from BMI is just as useful - see the BMI chart for the full ranges, and our guide to the limitations of BMI for context. To check where you carry weight, try the waist-to-height ratio.
Ideal body weight is an estimate of a healthy weight for a given height, originally developed for medical dosing. Several formulas exist (Robinson, Miller, Devine, Hamwi), and they disagree by a few kilograms, so the result is best read as a range rather than a single number.
No single formula is definitive - they were derived from different populations and none accounts for build, muscle, or body composition. That is why this calculator shows all four plus the healthy weight range from BMI 18.5-25, which is often the more useful guide.
No. These are population-level estimates, not a personal target or a prescription to lose or gain weight. Healthy weight depends on far more than height. If you have questions about your weight, discuss them with a qualified healthcare provider.
The healthy weight range shown is simply the weights that fall in the BMI 18.5-25 band for your height. You can calculate your current BMI on the main BMI calculator and see the full ranges on the BMI chart.
