For the indicative measurement, not for diagnostic purposes, of the subcutaneous tissue
and the conversion of this measurement into an indicative body fat percentage.
INTRODUCTION
The Skinfold Caliper is used to measure the thickness of "skinfolds".
Measurements are taken at selected sites. The resultant skinfold thickness is then translated by meansof skin-
fold tables to a percentage of body fat.
SKINFOLD MEASUREMENT PROCEDURES
Locate and measure each skinfold with care. Results may vary if measurements are not consistently taken at
the exact location with the same skinfold "pinch" and caliper pressure.
For each skinfold location use the same measurement procedure.
a. Take skinfold measurement directly on the skin, not through clothing.
b. Pick-up and hold skinfold with one hand, use other hand to measure the skinfold thickness with Skinfold
Caliper.
c. Take three measurements at each skinfold site. The final skinfold thickness at that skinfold site is the aver-
age of these three readings.
d. With a grease pencil, mark the measurement point on the skinfold site.
e. Pick-up skifold with the thumb and forefinger of your left hand.
f. Apply the skinfold caliper to the site so that the grease pencil mark on the skinfold side is halfway between
the caliper jaws.
g. Release your right thumb from the caliper lever so that the tips of the caliper jaw can exert their full force on
the skinfold.
h. Read the skinfold measurements (in millimeters) directly from the caliper dial.
i. Read the measurement two more times. A total of three measurements at each site is required for accurate
results.
j. The skinfold reading for the site is the average of the three readings.
k. Average skinfold reading = (R1 + R2 + R3) / 3
PERCENTAGE OF BODY FAT FROM SKINFOLD MEASUREMENTS
After the skinfold measurements have been taken, these measurements can be translated to BODY FAT CON-
TENT AS A PERCENTAGE OF BODY WEIGHT. These percentage figures vary with age and sex.
ADULT TABLES
To find the equivalent fat content, as a percentage of body weight, for adult males and females:
1. Add the four (4) average skinfold readings (biceps, triceps, subscapular and suprailiac)
2. Use the appropriate percentage of body weight table (male or female).
Find your body fat as a percentage of body weight at the intersection of the appropriate AGE BRACKET
column and SUM OF SKINFOLD row.
