A hypothesis that there would be appropriate figures for the exhibition wall arrangement in art museums was tested through questionnaire surveys conducted at 21 exhibition rooms in 10 art museums. Factor analysis showed that visitors' estimation to exhibition rooms was explained by 8 factors. Quantification I and multiple regression analysis showed that the main factors were the plainness of exhibition route and the visitors' satisfaction with exhibition rooms, and specific figures which improve the 2 factors respectively were indicated. Planning will be improved if appropriate reference is made to these key variables and factors.
