Abstract: The experiment based on the relationship between arm length、hand length、scope of arm activity and the pocket location and dimension design, in order to get quantitative and qualitative relationships between the arm length、hand dimension and the pocket location and dimension design. This article first select testing personnel who complied with the requirements by human body measurements, designed four wearing experiments, discuss the design principle of dress pocket based on human work efficiency. The results indicated the dress pocket design was affected by the arm length and hand dimension; fluctuation position of pocket could be estimated by waist length, and that the position was relevant with the tilt of pocket opening, in order to get better comfort we should design fluctuation position of pocket according to the tilt of pocket opening, the depth of pocketbag could be estimated by hand length and the width of pocketbag could be estimated by hand girth.
