Anthropometric Variability of the Male Population as a Basis for Developing Clothing Size Systems

This study investigates the variability of anthropometric characteristics in the male population and their impact on clothing size systems. The analysis is based on a sample of 937 adult males from the Republic of Croatia, focusing on age- and region-related differences in body height and chest girth. Descriptive statistical methods were employed to assess the distribution and relationships among variables. The results indicate significant variability in body dimensions influenced by age and regional factors. Body height decreases with increasing age, while chest girth increases up to middle age, then declines slightly. The study was conducted on a sample from one region of the Republic of Croatia, and the results were compared with data for the overall male population of Croatia. Regional differences are evident across all age groups, particularly in body height. The findings confirm the limitations of existing clothing size systems, which do not fully reflect the diversity of body proportions. The results emphasise the importance of research at the subpopulation level and the need to develop more adaptable, population-specific sizing approaches. Furthermore, integrating anthropometric data into digital garment construction systems is identified as a key step towards improving garment fit and production efficiency.
