Frequently Asked Questions

How is ideal weight calculated?

Several formulas exist. The Devine formula for men: 50kg + 2.3kg per inch over 5 feet. For women: 45.5kg + 2.3kg per inch over 5 feet. Our calculator shows results from multiple formulas plus the WHO healthy-BMI range.

Is ideal weight the same as healthy weight?

Ideal weight is a guideline, not a strict target. Healthy weight considers body composition, muscle mass, and individual factors. BMI and body fat percentage give a more complete picture.

Can I be healthy above my ideal weight?

Yes — ideal weight formulas don't account for muscle mass. Athletes and muscular individuals often weigh more than their calculated ideal weight while being very healthy.
