Ideal Body Weight (IBW) – How Much Should You Weigh?

Many people wonder about their “ideal” weight – often influenced by media images and social standards. In reality, ideal body weight (IBW) was never about appearance. It was originally developed to help doctors calculate safe medication dosages, as drug metabolism depends more on IBW than total body weight. Today, IBW is also widely used in healthcare and sports.

That said, there is no single perfect weight for everyone.

 

 

What IBW Can – and Can’t – Tell You

IBW is a reference value, not a health verdict. It does not account for muscle mass, body fat percentage, bone density, or lifestyle. As a result, athletes and fit individuals may appear “overweight” by IBW standards while being perfectly healthy.

Rather than chasing a specific number, long-term health depends more on:

• Regular physical activity
• Balanced, minimally processed foods
• Adequate sleep and stress management

 

Key Factors That Influence Ideal Weight

Age

After the late teen years, height remains mostly stable, but muscle mass naturally declines with age while body fat increases. Healthy habits can slow this process.

Gender

Men typically weigh more due to higher muscle mass and bone density. Women naturally carry a higher percentage of body fat.

Height

Taller individuals have more muscle and fat mass. At the same height, men generally weigh 10–20% more than women.

Body Frame Size

Bone structure matters. People with larger frames naturally weigh more than those with smaller frames—even at the same height.

 

How Ideal Body Weight Is Calculated

Most IBW formulas use a base weight at 5 feet, then add a fixed amount for each inch above that height. These formulas were designed for medical use and vary slightly based on research methods.

Common IBW Formulas

• Hamwi (1964)
  • Men: 48.0 kg + 2.7 kg per inch over 5 ft
  • Women: 45.5 kg + 2.2 kg per inch over 5 ft
• Devine (1974) (most widely used)
  • Men: 50.0 kg + 2.3 kg per inch
  • Women: 45.5 kg + 2.3 kg per inch
• Robinson (1983)
  • Men: 52 kg + 1.9 kg per inch
  • Women: 49 kg + 1.7 kg per inch
• Miller (1983)
  • Men: 56.2 kg + 1.41 kg per inch
  • Women: 53.1 kg + 1.36 kg per inch

 

Ideal Body Weight and BMI

The World Health Organization (WHO) defines a healthy BMI range as 18.5 to 25 for adults. BMI is commonly used to estimate healthy weight ranges and assess potential health risks.

For children and teens (ages 2–20), BMI is evaluated using percentiles rather than fixed values. A healthy range falls between the 5th and 85th percentile, as recommended by the CDC.

 

Calculator Limitations

All IBW and BMI formulas are general estimates. They do not consider:

• Muscle-to-fat ratio
• Activity level
• Physical disabilities
• Extreme body types

This calculator provides guidance, not a diagnosis. Use it as a starting point—your overall health matters far more than hitting a specific number.
