What is the distance people require to feel comfortable while interacting with others?

The distance people require to feel comfortable during interactions varies based on cultural norms and the nature of the relationship. Generally, personal space ranges from about 1.5 to 4 feet for social interactions, while intimate interactions may occur within 0 to 1.5 feet. However, in some cultures, closer proximity is acceptable, whereas in others, more space is preferred. Ultimately, individual comfort levels also play a significant role in determining the appropriate distance.
