About Skinfold Body Fat Testing

Skinfold testing estimates body fat percentage by measuring the thickness of skinfolds at specific sites on the body. This method is based on the principle that the amount of subcutaneous fat correlates with total body fat.

Measurement Sites
  • Chest: Diagonal fold halfway between the anterior axillary line and the nipple.
  • Abdomen: Vertical fold taken 2 cm to the right of the umbilicus.
  • Thigh: Vertical fold on the anterior midline of the thigh, midway between hip and knee joints.
  • Triceps: Vertical fold on the posterior midline of the upper arm, halfway between the acromion and olecranon processes.
  • Subscapular: Diagonal fold at a 45-degree angle, 1-2 cm below the inferior angle of the scapula.
  • Suprailiac: Diagonal fold above the iliac crest, along the anterior axillary line.
  • Midaxillary: Horizontal fold on the midaxillary line at the level of the xiphoid process.
  • Biceps: Vertical fold on the anterior aspect of the arm over the biceps muscle.
Formulas Used
  • Jackson/Pollock 3-Site: Uses different sites for men (chest, abdomen, thigh) and women (triceps, suprailiac, thigh).
  • Jackson/Pollock 4-Site: Includes biceps, triceps, subscapular, and suprailiac measurements.
  • Jackson/Pollock 7-Site: The most comprehensive formula using chest, midaxillary, triceps, subscapular, abdomen, suprailiac, and thigh measurements.
  • Durnin-Womersley: Uses biceps, triceps, subscapular, and suprailiac measurements with age-specific equations.
Measurement Tips
  • Take measurements on the right side of the body.
  • Pinch the skin and underlying fat away from the muscle.
  • Take each measurement 2-3 times and use the average.
  • Use quality calipers designed for body fat measurement.
  • Consistency in measurement technique is crucial for accuracy.
  • Wait at least 4 hours after exercise before taking measurements.
