Anthropometric measurements play a crucial role in assessing various characteristics of the human body, offering non-invasive and easily obtainable metrics applicable to both pediatric and adult populations, including athletes. These measurements serve diverse purposes such as diagnosing risk factors, optimizing athletic performance, and enabling patients to evaluate progress post-treatment. To ensure accurate assessments, using validated and reliable methods within a standardized protocol is essential, as advocated by the International Society for the Advancement of Kinanthropometry (ISAK). Dating back over seven decades, anthropometry stood as the primary technique for quantifying body size and proportions.

In 1921, initial equations used for estimating body fat depended on assessing body length, width, circumference, and skinfold thickness. The technique's distinct advantages lie in its portability, non-invasiveness, cost-effectiveness, suitability for field studies, and a substantial existing literature. This chapter underscores the importance of employing validated methods within standardized protocols, emphasizing ISAK guidelines. It recognizes the historical significance of anthropometry and its enduring relevance, especially in the context of predicting body fat. The chapter also highlights the portability and cost-effectiveness of anthropometric tools, positioning them as valuable instruments in both research and practical applications. Overall, it positions anthropometry as a fundamental and versatile approach, providing a comprehensive guide for practitioners, researchers, and individuals involved in obtaining accurate and meaningful anthropometric measurements.
