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.
