Skinfold measurements are a method used to estimate body fat percentage by measuring the thickness of skinfolds at specific sites on the body. A caliper is used to pinch the skin and underlying fat, providing a reading that reflects the amount of subcutaneous fat. Common measurement sites include the abdomen, triceps, and thigh. These measurements are often taken by trained professionals to ensure accuracy and consistency. The results can be compared to standardized charts to assess body composition. While skinfold measurements are a practical tool, they may not account for all factors influencing body fat distribution.
