The evaluation of rooms is one of the most important but rarely investigated questions in architectural psychology. This study looked into relationships between room size, relatively constant personality factors, present moods, demographic variables, and room evaluation. The present mood of a subject was closely related to the evaluation of rooms, both real and ideal. The more balanced the mood, the more positive the judgment. Personality factors, demographic variables, and room size showed little or no relation to the evaluation of rooms. The results clarified the highly emotional nature of room evaluation.
