The purpose of this study was to investigate the actual size of tables and chairs in small restaurants. The examined objets were 48 restaurants serving flour-based, korean style and japanese style meals. Those restaurants are currently being operated at six universities in Seoul, and their sizes are limited under $66m^2$. The results of this study were as follows ; 1 . In small restaurants, the size of the seat for one person is $0.346m^2$on the average. The range of the size starts from $0.285m^2$to $0.403m^2$, showing a great difference. 2. The most common size of tables in small restaurants is the oblong style of $600{ imes}900$ for four people. The smallest size is $440{ imes}710$, while the biggest one is $700{ imes}1000$, showing a great number of variation. If the most common size of tables is set to be the general size of tables in small restaurants, it will be $600{ imes}900$. 3. The sizes of the seats for chairs used in small restaurants start from $270{ imes}270$ to $430{ imes}430$. The most common size of the seats for chairs is $400{ imes}400$, only showing a small number. For the cases of tables with the most common size of $600{ imes}900$, the width of the seats for chairs should be under 400. 4. For the height between the table and the seats of the chair, the distance from 270 to 300 is relevant. However, according to the results of the investigation, it seems that there are more cases of the distance from 250 to 260 than that from 270 to 300.
