Military backpack used by army soldiers is a necessary item designed to carry military supplies. Considering that soldiers have to carry the backpacks over an average of 50km per day, it is very important that they fit the size of the soldiers’ body comfortably. However, only one size of the military backpack is supplied in the army. Previous studies have attempted to improve the fit of the military backpack by changing frame structure of the backpack to distribute the load concentrated at a specific body part, or applying adjustable straps for shoulder or chest. However, there is a lack of studies for the military backpack design to reflect the characteristics of users with various body sizes. Therefore, this study proposed a methodology to derive design variables of the military backpack to reflect users’ body size characteristics. The back panel size that 58 % of army soldiers were unsatisfied in a preliminary survey was studied to derive the optimal design dimension using the following steps. First, the Size Korea data was used to choose the human body size variables which can be reflected in the design variables. Next, a correlation analysis was applied among the variables to select the human body size variables that best fit the dimension of the military backpack. Finally, clustering analysis was used and five types of back panel size were developed to be applicable to soldiers with different body size characteristics. This methodology can also be applied to derive optimal dimensions of other design parameters such as shoulder strap length, waist pad width, etc. Then, the military backpack can be better improved to be fitted to the wearer and the load can be distributed with wider contact area of the wearer.
