What BMI can and can't tell you at 5′8″
BMI is weight divided by height squared, so at a fixed height it rises in step with weight — the table above is that relationship for 5′8″. It's a quick screening number, not a measure of body fat.
Because muscle is denser than fat, a muscular 5′8″ adult weighing around 181 lb can register as overweight while carrying little excess fat. Waist measurements add context BMI misses: the Waist-to-Height Ratio and Body Fat calculators are good next steps.
These categories apply to adults. Children and teens are assessed with age- and sex-specific BMI percentiles instead.
