Using the Durnan Method
To determine body fat by the skin caliper method using the Durnan Formula, four points are measured on
the right side of the body according to the table below. First, using the thumb and forefinger of the left
hand, grasp the skin about 1 cm above the site location. Hold the calipers perpendicular to the site and
measure while still grasping the skin. Take three readings and record the average caliper measurement
for that site. Now measure the other sites. The four caliper measurements are then summed. This total
measurement in millimeters is then matched up with the table on the following page for men or women.
Taking readings after exercise will give false readings.
