How it's calculated
BMI = weight (lb) × 703 ÷ height (in)²
Height = 5 × 12 + 1 = 61 inches
Example: at 61 inches and 160 lb, BMI = 160 × 703 ÷ 3,721 = 30.2. BMI is the same for men and women, but it doesn't separate muscle from fat, so very muscular people can show as overweight. Waist size and body fat give a fuller picture.
