Quick Answer
Ideal body weight formulas estimate healthy weight based on height and gender. The Devine formula: Men = 50 + 2.3kg per inch over 5 feet; Women = 45.5 + 2.3kg per inch over 5 feet. For a 5'10" man, ideal weight is approximately 166 lbs (75.3 kg). Calculate with multiple formulas at practicalwebtools.com.
Key Facts
- Devine formula (most used): Men = 50 + 2.3(height in inches - 60) kg
- Robinson formula: Men = 52 + 1.9(h-60) kg; Women = 49 + 1.7(h-60) kg
- Miller formula: Men = 56.2 + 1.41(h-60) kg; Women = 53.1 + 1.36(h-60) kg
- Hamwi formula: Men = 48 + 2.7(h-60) kg; Women = 45.5 + 2.2(h-60) kg
- Formulas give a target, not exact optimal weight
- Healthy weight varies by body frame, muscle mass, and age
- Focus on healthy ranges rather than single numbers
Frequently Asked Questions
Ideal body weight (IBW) is an estimated weight that may be associated with optimal health based on your height and gender. Multiple formulas exist because "ideal" varies based on frame size, muscle mass, and individual factors.
No single formula is "best" for everyone. The Devine formula is commonly used in medicine. Robinson and Miller formulas may be more accurate for some people. Using the average of multiple formulas often provides a better estimate.
Larger bone structures can healthily carry more weight. Measure your wrist circumference to estimate frame size: small (<6" men, <5.5" women), medium (6-7" men, 5.5-6.25" women), large (>7" men, >6.25" women).
BMI-based ranges (18.5-24.9) provide a general guideline but don't account for muscle mass. Athletes may be above the range while healthy. Use BMI alongside other measures like body fat percentage.
Each formula was developed from different population studies and uses different mathematical approaches. This variation reflects the reality that "ideal" weight varies by individual. Consider the range rather than any single number.
