Frequently Asked Questions about the Ideal Weight Calculator
What formulas does this calculator use?
It averages four classic equations: Devine (1974), Hamwi (1964), Miller (1983), and Robinson (1983). Each uses your height in inches over 5 feet, with separate constants for men and women.
How accurate is ideal body weight?
These formulas predate modern body composition science and were built for medication dosing, not health targets. They ignore muscle mass, frame size, and age, so treat the result as a rough reference, not a hard goal.
What is a typical ideal weight range?
For a 5'10" (178 cm) man, the formulas land between 70 and 76 kg (154 to 168 lb). For a 5'5" (165 cm) woman, expect 56 to 62 kg (123 to 137 lb). Healthy weight can sit well above or below this band.
Should I aim for my ideal body weight?
Not necessarily. A muscular athlete will exceed it without excess fat, and a small-framed person may sit below it naturally. Talk to a doctor or dietitian before setting a weight target based on this number alone.
Is ideal body weight the same as healthy weight?
No. Healthy weight is usually defined by BMI, waist circumference, and body fat percentage together. The IBW formulas are a single estimate from height and sex, used historically for drug dosing and military standards.
