Body Fat Percentage Calculator
Measure with a soft tape: neck below the larynx, waist at the navel, hip at the widest point.
About this calculator
The US Navy method estimates body fat from tape measurements. It is convenient but accurate only to within about 3-4 percentage points. Asians usually carry more body fat at the same BMI, so aim for the lower half of the average range. Not suitable for children or pregnancy.
Results are for information only and are not a diagnosis. Consult a doctor for medical advice.
