There are four distance zones that define personal space in social interactions: intimate, personal, social, and public. The intimate zone ranges from direct contact to 60 cm and is for very close relationships. The personal zone is 60cm to 1.5m and is for friends and family. The social zone is 1.5-3m and is for strangers and acquaintances. The public zone is over 3m and is for situations like public speaking. The appropriate distance depends on the relationship, status, gender, and culture between individuals.
