FAQ
Frequently Asked Questions
How do I calculate my ideal weight?
Common formulas include Broca (height in cm minus 100), Creff (accounts for body frame), and BMI-based (target BMI of 22 times height squared). However, ideal weight is individual and depends on many factors.
Is BMI a reliable indicator of health?
BMI has limitations: it does not distinguish between muscle and fat mass, does not consider body fat distribution, and may not be accurate for athletes or elderly individuals. Waist circumference is an important additional measure.
Does this calculator replace a doctor visit?
No. This calculator provides general orientation only. For medical questions, or before starting a diet, therapy or treatment, always consult a qualified physician or therapist.

What is the Ideal Weight Calculator?
The ideal weight calculator computes ideal weight using various formulas and shows a healthy weight range.
How does the Ideal Weight Calculator work?
Enter height, sex and age. The calculator computes ideal weight using the Broca formula (height - 100, minus 10-15%), Creff formula and the BMI normal range (18.5-24.9). The recommended range is shown as a span.
Key Data and Facts
Broca formula: ideal weight = (height in cm - 100) * 0.9 (men) or 0.85 (women). BMI normal range: 18.5-24.9. Individual factors matter: muscle mass, body frame, etc.
Step-by-Step Guide
How to calculate your ideal weight step by step: 1. Enter your height: in cm, measured without shoes. 2. State your sex and age: the formulas take sex-specific differences into account. 3. Apply the Broca formula: normal weight = height (cm) - 100. Ideal weight men = normal weight x 0.90. Ideal weight women = normal weight x 0.85. 4. BMI method as a comparison: the healthy BMI range is 18.5-24.9. From this it follows: lower limit = 18.5 x (height in m)2. Upper limit = 24.9 x (height in m)2. 5. Creff formula (takes body build into account): slim build: x 0.9. Normal build: x 1.0. Sturdy build: x 1.1. 6. Interpret the result: the ideal weight is a guide value. Individual factors such as muscle mass, bone structure and state of health are equally relevant.
Calculation Example
Frau, 170 cm: Broca-Normalgewicht = 170 - 100 = 70 kg. Idealgewicht = 70 x 0,85 = 59,5 kg. BMI-Normalbereich: 53,5-71,9 kg.
