TOOLFind a healthy weight for your height
Rather than a single "perfect" number, a healthy weight is a range. This calculator's headline figure comes from the healthy BMI band of 18.5 to 24.9 applied to your height — the range most health bodies use. Below it, four classic clinical formulas (Devine, Robinson, Miller and Hamwi) give single-point estimates for comparison.
How the formulas differ
All four use only your height and sex and were originally created for medication dosing, so they return slightly different results. They tend to cluster close together, which is why showing them side by side is useful. Your frame size, muscle mass and body composition all shift where within the range you'll feel and perform best.
This is a general estimate for educational purposes only and is not medical advice. A healthy weight varies with body composition, muscle mass and other factors. Consult a qualified healthcare professional for personal guidance.
Frequently asked questions
What is my ideal weight?
There is no single ideal weight. This tool shows a healthy weight range from the healthy BMI band (18.5 to 24.9) for your height, plus estimates from four classic formulas. Any weight within the range can be healthy depending on your build and muscle.
Which ideal weight formula is best?
The formulas by Devine, Robinson, Miller and Hamwi were designed decades ago mainly for medication dosing and give slightly different single figures. Treating the healthy BMI range as your target and the formulas as reference points is the most balanced approach.
Does ideal weight account for muscle?
No. These formulas use only height and sex, so a muscular or very lean person may sit outside the range and still be healthy. Combine the result with a body fat estimate for a fuller picture.
