Ideal weight for women and men at 5′8″
BMI is the same for women and men, but ideal-body-weight formulas — used by doctors to dose some medicines — give separate figures. At 5′8″, they put a woman's ideal weight at about 138 lb – 141 lb and a man's at about 148 lb – 153 lb. Anywhere in the healthy BMI range above is still a healthy weight.
| Formula | Women | Men |
|---|---|---|
| Robinson (1983) | 138 lb | 148 lb |
| Miller (1983) | 141 lb | 149 lb |

How BMI is worked out at 5′8″
5′8″ is 68 inches. In US units, BMI = 703 × weight in pounds ÷ height in inches squared, and 68² = 4,624. So 170 lb gives 703 × 170 ÷ 4,624 = 25.8. The table does this for every 5 pounds.
The categories are the World Health Organization's adult ranges, used by the CDC. BMI does not tell muscle from fat, so also check your waist-to-height ratio: at 5′8″, keep your waist under 34 inches. For an exact weight, use the BMI calculator, which takes pounds or kilograms and feet or centimetres.
