What is a disadvantage of using calipers to measure body fat percentage?

Using calipers to measure body fat percentage does indeed have a notable disadvantage related to user variability. This method relies heavily on the skill and technique of the person taking the measurements. Different individuals can apply varying amounts of pressure or measure at slightly different sites, leading to inconsistencies in the results. Additionally, the effectiveness of skinfold measurements can be influenced by factors such as the operator's experience, training, and familiarity with specific anatomical landmarks. This variability can result in misleading conclusions about an individual's body fat percentage if measurements are not taken consistently.

While other methods may have attributes such as higher costs or time requirements, the issue of user variability presents a significant challenge in achieving accurate and reliable measurements when using calipers.
