Ideal weight is an estimated healthy weight range for your height and frame. There is no single 'correct' ideal weight — different medical formulas give different results, which is why this calculator shows multiple ranges.

What Is Idealgewicht-Rechner?
How to Calculate — The Devine, Robinson, Miller & Hamwi Medical Formulas Formula
We use 5 distinct clinical formulas: Devine (1974), Robinson (1983), Miller (1983), Hamwi (1964), and a back-calculation of the healthy BMI range (18.5-24.9).
- Select your gender and enter your exact height.
- Review the results across the 5 different formulas.
- Use the range as a generalized goal, rather than obsessing over a single exact number.

Frequently Asked Questions
Why do the formulas give different numbers?
Each formula was developed by different medical researchers at different times using different population samples. Viewing them as a range is best.
Do these formulas account for muscle mass?
No, they are based strictly on height and gender. If you are highly muscular, your healthy weight will be higher than these estimates.
Which formula is the most accurate?
The Devine formula is the most widely used in medical settings for drug dosing, but the BMI range provides the broadest healthy target.
Should I try to hit the exact ideal weight?
No. It is a guideline. Body composition (muscle vs fat) and how you feel are far more important than a specific number on the scale.
