Reference for adults. It doesn't account for muscle mass or body composition.

How it works

  1. Devine, Robinson, Miller and Hamwi start from a base weight and add an amount for every inch over 5 feet.
  2. Broca (modified): (height in cm − 100) × 0.9 for men and × 0.85 for women.
  3. The healthy BMI range is the weight that keeps BMI between 18.5 and 24.9 at that height.

FAQ

Why do the formulas give different numbers?

Each one was built on different data for different purposes — some for drug dosing. That's why we show a range, not one exact number.

Should ideal weight be a client's goal?

As a reference, yes. But body composition, history and goals matter more than the number on the scale. Use it alongside a skinfold or measurement assessment.

In Trainer Fácil, clients fill in weight and measurements in the app and you track progress assessment after assessment.
