What is the ideal distance between a person's eyes?

The ideal distance between a person's eyes is commonly regarded as the width of one eye. This standard is based on aesthetic proportions observed in the human face. In symmetrical faces, the distance between the eyes is typically just about the width of one eye. This measurement serves as a guiding principle in fields such as esthetics, design, and portraiture, as it helps in achieving balanced proportions that are often perceived as more attractive or harmonious.

Understanding this helps estheticians and beauty professionals to assess facial features accurately when providing services like makeup application, brow shaping, and other cosmetic treatments. The ability to recognize and apply these facial proportions can enhance the overall appearance and client satisfaction.
