What Is Ideal Weight?

Ideal body weight is a target weight range considered healthy for a given height and body frame. Multiple medical formulas have been developed over the years, each with slightly different results. No single formula is perfect — use these as guidelines rather than absolute targets.

Common Ideal Weight Formulas

Hamwi Formula (1964)

Men: 48 kg + 2.7 kg for each inch over 5 feet
Women: 45.5 kg + 2.2 kg for each inch over 5 feet

Devine Formula (1974)

Men: 50 kg + 2.3 kg per inch over 5 feet
Women: 45.5 kg + 2.3 kg per inch over 5 feet

BMI-Based Range

Many doctors use BMI 18.5–24.9 to define a healthy weight range for a given height, which gives a range rather than a single target.

Limitations

Ideal weight formulas do not account for:

  • Body frame size (small, medium, large)
  • Muscle mass (athletes will appear "overweight")
  • Age-related changes in body composition
  • Ethnic and genetic differences

A Healthier Approach

Instead of chasing a specific number, focus on body fat percentage, waist circumference, and metabolic health markers (blood pressure, blood sugar, cholesterol). A fit, muscular person at 80 kg may be far healthier than someone at 70 kg with high body fat.
