Purpose: This paper purposes to formulate 3D shoe size by using scanning camera and link to CAD modeling. Design/methodology/approach: The research design is divided into four groups with different ages and sex. The first group is boys and girls with 6-10 years old. The second group is teenagers with 11 - 20 years old. The third group is university students and working people with 21-30 year olds. The last group is professional working people group with 31 - 48 years old. The sample populations are selected and measured their feet both left and right sides. Each group contains ten to eighteen people except the child group which contains three to five children. The sampling sizes are 97 people. The 3D scanning camera is used in order to obtain the all sides of the feet. The process contains five steps in five foot positions; the middle foot, the 45° left foot, the 90° left foot, the 45° right foot, 90° right foot. The foot data image of all the sampling populations are classified in the same and similar sizes. Eight groups are determined that is formulated by eight sizes of the Thai shoe size. The size is started from the 19 W7.4 H6.7 to 27 W10.8 H9.1 which represents 3D shoe size. Findings: The research result has investigated the new standard size model based on Thai local populations in 3D models. This study shows precisely the customized shoe sizes for individual people as well as the grouping shoe sizes for Thai people. Practical implications: It can make benefits for shoe designers, customers and manufacturers. Originality/value: This study shows precisely the customized shoe sizes for individual people as well as the grouping shoe sizes for Thai people.
