What is the "golden ratio" used for in design?

The concept of the "golden ratio," approximately 1.618, is widely recognized in design for its ability to establish aesthetically pleasing proportions. This mathematical ratio has been utilized throughout history in art, architecture, and various design disciplines because it creates a sense of harmony and balance that is visually appealing to the human eye.

In interior design, applying the golden ratio can aid in determining the dimensions of spaces, shapes, and elements, ensuring that they are proportionate and harmonious within the overall design. By leveraging these proportions, designers can evoke a sense of well-being and elegance, effectively engaging viewers and occupants in a space.

Consequently, this option perfectly encapsulates the purpose and significance of the golden ratio within design practices. Other options, while relevant to different aspects of design and interior layout, do not directly align with the fundamental application of the golden ratio in promoting aesthetic harmony.
