Formula
Ideal weight formulas: Devine (male): 50 + 2.3 × (height/2.54 − 60); Robinson (male): 52 + 1.9 × (height/2.54 − 60); Miller (male): 56.2 + 1.41 × (height/2.54 − 60); Hamwi (male): 48 + 2.7 × (height/2.54 − 60).
Frequently Asked Questions
Which ideal weight formula is most accurate?
No single formula is perfectly accurate. It is recommended to use the average range from several formulas for a more objective estimate.
Why do the formula results differ?
Each formula was developed from different research studies and populations. The variation reflects the natural range of healthy weight.
Do these formulas account for age?
No, these formulas only consider height and gender. For a more comprehensive assessment, also consider BMI and body composition analysis.
