Abstract: The present invention relates to a method of determining content screening suitabilities in a multi-projection theater including a plurality of projection planes. More particularly, the present invention relates to a method of determining content screening suitabilities based on a series of operation equations using content attribute values, such as the horizontal length and vertical length of an output screen when content is played back, and theater attribute values, such as the length and height of the surface of a front or side wall within a theater building. The method may include calculating at least one of a screen attribute value and a theater attribute value, calculating a suitability based on the screen attribute value or the theater attribute value, and determining whether the calculated suitability falls within a predetermined range.
