how to calculate ibw for under 5 feet?
Calculating Ideal Body Weight If you're under 5 feet tall, subtract 2 pounds for each inch under 5 feet. Using the equation, a 5-foot, 4-inch tall woman would have an ideal weight of 120 pounds: IBW = 100 + (4 x 5) = 120. A man who is 6 feet tall has an IBW of 178 pounds: IBW = 106 + (12 x 6) = 178.
