Frequently Asked Questions
Multiple formulas exist: Devine (most common for medication dosing), Robinson, Miller, and Hamwi. They use height as the primary factor. Results vary by 10-15 lbs between formulas. No single "ideal" weight exists - consider body composition instead.
Not exactly. Ideal weight formulas give a single number based on height. Healthy weight is a range (usually BMI 18.5-24.9). A muscular person may weigh more than their "ideal" but be very healthy. Use ideal weight as a reference, not a strict goal.
The Devine formula is most widely used in medicine. Robinson is considered more accurate for women. Miller formula gives slightly higher weights. For best results, average multiple formulas and consider your frame size (small, medium, large).
People with larger bone structures naturally weigh more. Measure wrist circumference: Small frame (under 6" men, 5.5" women), Medium (6-7" men, 5.5-6.5" women), Large (over 7" men, 6.5" women). Add/subtract 10% from ideal weight for frame size.
