How it's calculated
BMI = weight (lb) × 703 ÷ height (in)²
Height = 4 × 12 + 10 = 58 inches
Example: at 58 inches and 160 lb, BMI = 160 × 703 ÷ 3,364 = 33.4. 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.
