About These Methods

Navy Method: Uses circumference measurements (waist, neck, hip). No calipers needed. Good general estimate.

3-Site Skinfold: Jackson-Pollock formula using 3 skinfold sites. Requires calipers. More accurate than circumference methods.

7-Site Skinfold: Jackson-Pollock formula using 7 skinfold sites. The gold standard for skinfold testing. Most accurate of the three.
