A Standard Sizing System for Clothes Based on Anthropometric Statistics of Ghanaian Boys Aged Seven to Twelve Years

Abstract

The study developed a sizing system for pre-teen boys (7 to 12 years), using anthropometric measurements. Specifically, it determined key dimensions; cluster; groupings; and size intervals of Ghanaian pre-teen boys’ measurements; and created a size chart. The study was conducted in Greater Accra region of Ghana using an experimental research design. Population consisted 324,288 Ghanaian pre-teen boys. It adopted the International Organization for Standardization (ISO) 8559 (2017; 2018) anthropometric measurement protocols. Relationship between body dimensions were assessed using Pearson’s correlation coefficient, based on the British Standard Institution (BSI) standard 7231 (BSI, 1990) related to clothing. Key dimensions were selected based on correlation among the 27 dimensions. Results include four key dimensions; height, chest, waist, and hips, for creation of the size chart. Sizing structure was based on centilong system, which applies a 6 cm yearly increment in height of children, resulting in nine clusters for six age group studied. Height was main parameter for size designation, in addition to age and key dimensions. Also, three size variations; small medium and large were created for each size category.
