The present disclosure relates to a method and a device for estimating suitability as a multi-screen projecting type theatre and the method for estimating the suitability as the multi-screen projecting type theatre includes: creating a plurality of image representation models (M) respectively corresponding to a plurality of candidate theatres; calculating a total image representation model ({circumflex over (M)}total) corresponding to all of the plurality of candidate theatres; and calculating a deviation between the total image representation model ({circumflex over (M)}total) and each of the plurality of image representation models (M) of the target theatre and estimating theatre suitability of the target theatre based on the deviation when one target theatre is selected among the plurality of candidate theatres.
