Ideal Weight Calculator

Ideal weight is the healthiest weight for your height, typically defined as BMI 22. Research by the Japan Society for the Study of Obesity demonstrates that people with BMI 22 have the lowest disease risk.

Beauty weight (BMI 20) represents a slim, aesthetically pleasing appearance, while model weight (BMI 18) reflects the standard for models and celebrities. These three are calculated using BMI (weight kg ÷ height m²).

The Broca method, developed by French surgeon Paul Broca in the 19th century, offers a simpler, traditional approach. It uses (height − 100) × 0.9 for men and (height − 100) × 0.85 for women. Medical validation shows it achieves equivalent accuracy to more complex formulas.

This tool calculates all four standards simultaneously, providing a comprehensive view of different weight targets. Use these values as reference points for healthy weight management. Extremely low body weight carries health risks — consult a physician if concerned.
