Man is a social being by nature and the environment surrounding him is the place of formation and establishment of his social relations. The amount and how the environment affects human performance has always been one of the important concerns of environmental designers. Among them, Bazars are highly important as public, thriving and frequented places. The purpose of this research is to find out the influencing factors of the body on the interaction in it and to investigate the role of Tabriz Bazar space as a living and dynamic example of the traditional markets of Iran on the interactions in it. In this research, a descriptive-analytical method is used to investigate social interactions and the effect of the body on the amount of interactions, and social interactions examine the impact of the Bazar on interactions and comparative comparison of different activities of a group; Among the houses of this Bazar are Amir and Dodari houses, which are different from each other in terms of function and geometric shape and create different interactions. The results of the research indicate that the three factors of communication, interconnectedness and control have a direct effect on the accessibility, permeability and flexibility of space, and all three of these factors are among the factors that promote social interactions from the perspective of space; The investigation in both halls shows the effect of the centrality of the space and entrances on improving traffic and focusing the audience and the centrality of these two items on attracting less audience and creating cozy spaces for social interactions. Examining the physical factors shows the positive effect of proper flooring, visibility, legibility, use of natural elements in the amount of social interactions, and each of the components of suitable furniture, access and pause spaces are different in the two houses, which indicate the difference in the amount of interaction in the second house.
