What is a skinfold caliper?

A skinfold caliper is a tool used to measure the thickness of skinfolds, which is a measure of body fat. It consists of two arms with a spring-loaded caliper that is placed over the skinfold and then released to measure the thickness. Skinfold calipers are commonly used in fitness and health assessments to estimate body fat percentage and monitor changes in body composition. They provide a quick and non-invasive method of assessing subcutaneous fat tissue.
