Ideal Weight Questions
Which ideal weight formula is most accurate?+
No single formula is definitively "best" — each was developed for different clinical contexts. The Devine formula (1974) is the most widely used in clinical settings, particularly for drug dosing. The Hamwi formula is popular in dietetics. BMI-based ranges (18.5-24.9) are considered the most evidence-backed for general population health. Using an average of multiple formulas gives a more balanced estimate than any single one.
Does ideal weight account for muscle mass?+
No. Traditional ideal weight formulas only use height and sex — they do not account for muscle mass, bone density, or body frame size. An athletic person with high muscle mass may be "overweight" by these formulas despite having low body fat. For a more accurate assessment, combine ideal weight with body fat percentage. A muscular male at 200 lbs and 10% body fat is far healthier than a sedentary male at 175 lbs and 28% body fat.
How much should a 5-foot-10 male weigh?+
For a 5'10" (178 cm) male: Devine = 166 lbs (75.3 kg), Robinson = 163 lbs (74 kg), Hamwi = 165 lbs (74.8 kg). The BMI healthy range (18.5-24.9) gives approximately 129-174 lbs (58-79 kg). The average across formulas is typically around 164-167 lbs (74-76 kg). Use the calculator above for your exact height.
