The purpose of this study is to analyze space size in the apartment unit plan towards optimal space configuration in order to offer the helpful information to housing designers. For this, we analyzed 432 samples using the Excel 2003 program. The major results of this study are as follows. 1) as the unit size gets bigger, the proportion of the usable area is increased. 2) as the unit size gets bigger, the number of spaces is increased and spaces are divided although they have the same function. 3) living room has the highest proportion in each unit, master room and kitchen are followed. 4) the proportion of living room, kitchen and entrance hall is not fluctuated while that of bedroom and bathroom is decreased. 5) there is a big gap between maximum size and minimum size of kitchen, entrance hall, bathroom and dressing room.
