The Skinfold caliper is used to measure the thickness of “skin- folds”. Measurements are taken at selected sites. The resultant skinfold thickness is then translated by means of skinfold tables to a percentage of body fat.
The skin fold can be used when you hold the pair of calipers using your right hand with the thumb on the upper arm and index finger on the lower arm. Place the jaw ends over the skinfold while continuing to pinch the skinfold with your left hand. Using your right thumb, press down where indicated on the caliper until you feel a slight click.
