How to Use Our Reverse BMI Calculator

Our reverse BMI calculator makes it incredibly simple to determine your ideal weight. Just follow these 3 steps:

1. Enter Your Height: Input in centimeters, feet/inches, or meters

2. Select Target BMI: Choose between standard ranges (18.5-24.9) or customize for your goals

3. Get Instant Results: See the exact weight needed to reach your target BMI

*Example: For someone 5’9″ (175cm) targeting a BMI of 22 = ~154 lbs (70 kg)*

Traditional BMI calculators only tell you if you’re underweight or overweight. Our reverse BMI calculator answers the question you actually care about:
“What should I weigh for my height and health goals?”

Key benefits:
Removes all guesswork from weight management
Works perfectly for both men and women
More practical than standard BMI measurements
Helps set realistic fitness targets

(Pro Tip: Combine with our waist-hip ratio calculator for complete body analysis!)

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

1. Ideal Body Weight Formula

   • Men: 50kg + 2.3kg per inch over 5 feet

   • Women: 45.5kg + 2.3kg per inch over 5 feet

2. 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
