Understanding the Reverse BMI Formula
The Basic Calculation
Target Weight (kg) = Desired BMI × (Height in meters)²
Practical example:
Height: 1.65m (5’5″)
Target BMI: 21 (mid-range healthy)
Calculation: 21 × (1.65 × 1.65) = 57.2 kg (~126 lbs)
Advanced Calculation Methods
Ideal Body Weight Formula
Men: 50kg + 2.3kg per inch over 5 feet
Women: 45.5kg + 2.3kg per inch over 5 feet
Adjustments for Athletes
Add 5-10% to account for muscle mass
Expert Tip: For most accurate results, cross-check with our body fat percentage calculator.
BMI Variations: Standard vs. Asian Guidelines
While our calculator uses standard BMI ranges, it’s important to know that Asian populations often require different standards
- Healthy BMI Range:
- Standard BMI: 18.5 to 24.9
- Asian BMI: 18.5 to 23
- Overweight Threshold:
- Standard BMI: 25 and above
- Asian BMI: 23 and above
Important Note: If you’re of Asian descent, you may want to target BMI 20-23 rather than the standard 24.9
