Healthy Weight Calculator

Calculate your ideal weight range based on your height, gender, and body frame size. This calculator uses the Hamwi formula, a well-established method for determining healthy weight ranges that takes into account individual body characteristics.

How to Use This Calculator

1. Select your preferred height unit (centimeters or feet/inches)
2. Enter your height
3. Select your gender
4. Choose your body frame size
5. Click “Calculate” to see your healthy weight range

Understanding Your Results

The calculator provides a weight range rather than a single number because healthy weight varies based on several factors. The range accounts for your:

• Height
• Gender
• Body frame size (small, medium, or large)

Body Frame Size Guide

To determine your frame size:

• Small Frame: Your wrist circumference is less than 6.25 inches (for men) or 5.5 inches (for women)
• Medium Frame: Your wrist circumference is 6.25-7 inches (for men) or 5.5-5.75 inches (for women)
• Large Frame: Your wrist circumference is over 7 inches (for men) or 5.75 inches (for women)

Calculation Method

This calculator uses the Hamwi formula, which is widely accepted in the medical community:

• For Men: Ideal Weight = 48 kg + 2.7 kg for each inch over 5 feet
• For Women: Ideal Weight = 45.5 kg + 2.2 kg for each inch over 5 feet

The formula is then adjusted based on frame size:

• Small Frame: 90-95% of the calculated weight
• Medium Frame: 95-105% of the calculated weight
• Large Frame: 105-110% of the calculated weight

Frequently Asked Questions

Why does frame size matter?

Body frame size affects how weight is distributed and what constitutes a healthy weight range. Someone with a larger frame can typically maintain a higher healthy weight than someone of the same height with a smaller frame.

What if I’m outside the recommended range?

Being outside the recommended range doesn’t necessarily indicate a health problem. Consult with a healthcare provider for personalized advice based on your specific situation.
