Ideal Weight Calculator
Estimate ideal body weight using common formulas and compare with a BMI-based healthy weight range.
What is ideal body weight?
Ideal body weight is an estimate based on height and gender using simplified medical formulas. It’s often used for quick screening or dosage calculations, but it does not account for muscle mass, body composition, or individual health conditions.
Ideal weight formulas explained
Devine, Robinson, Miller, and Hamwi are common formulas that estimate ideal weight using a baseline of 5 ft (60 inches) and an added amount per inch above that height. Results can vary across formulas, so comparison can help you understand the range.
Ideal weight vs healthy weight range
This page also shows a BMI-based healthy weight range (BMI 18.5–24.9). The BMI range is another reference point and may not match ideal-weight formulas exactly.
