What is the standard error margin for skinfold measurements?

The standard error margin for skinfold measurements is generally recognized as being around ±3.5%. This value reflects the inherent variability and potential inaccuracies in the measurement process, which can include factors such as the skill of the assessor, the calibration of the caliper, and the anatomical site measurement technique. Skinfold measurements, widely used to estimate body fat percentage, depend on accurate and consistent technique to provide reliable results. While other error margins might be cited in different contexts or studies, the standard accepted in the field aligns with the ±3.5% value, making it a commonly referenced figure among exercise physiologists and health professionals.
