⚖️ Ideal Weight Calculator

What is Ideal Weight Calculator?

The Ideal Weight Calculator estimates your ideal body weight from your height using four well-known clinical formulas - Devine, Robinson, Miller and Hamwi - each tuned slightly differently for men and women. Enter your height in centimeters or feet and inches, pick a primary formula or compare all four at once, and optionally add your current weight to see how far you are from each target. The same height is also mapped to a healthy BMI band of 18.5 to 24.9, giving you a range of sensible weights rather than a single number. Everything is computed locally in your browser with no account and no data upload.

Frequently Asked Questions

• What is ideal body weight?▾
  Ideal body weight is a formula-based estimate of a healthy weight for your height and sex. It is a reference target rather than a medical prescription, and it differs from BMI which describes a broad healthy range instead of a single number.
• Why do the four formulas give different results?▾
  The Devine, Robinson, Miller and Hamwi formulas were published in different decades using different patient groups and rounding rules. Devine and Hamwi tend to give slightly higher targets while Robinson and Miller usually land a bit lower, so a small spread between them is normal.
• Is the BMI range a better guide than these formulas?▾
  For most people the BMI band is more practical because it shows a healthy weight range of 18.5 to 24.9 for your exact height. The formula targets are best used as a single reference point that should sit inside that range.
