What is the Golden Ratio? The Golden Ratio is a mathematical ratio often found in nature that can be used to create aesthetically pleasing compositions. It is often symbolised as the Greek letter Phi. How does it work? From Da Vinci’s Vitruvian Man through to Le Corbusier’s Modulor project, the Golden Ratio, also known as the Golden Mean or Divine Proportion, has for centuries been used in paintings, architecture, sculpture, design and photography. In nature, it can be found mostly in the plant world where, mathematically speaking, everything from the rind of a pineapple to the seed formation in a sunflower has the same pattern: 1, 2, 3, 5, 8, 13, 21, 34 and so on. This sequence, also known as The Fibonacci, is where a number is found by adding up the two numbers before it. Any two successive Fibonacci numbers have a ratio very close to the Golden Ratio, resulting in either a Golden Ratio spiral or Golden Rectangle. Why is it important? Intrinsically pleasing to the eye, the Golden Ratio provides a compositional framework that feels naturally balanced to the observer, which is why it is often used by architects and product designers. When we began working on the proportions of our TSL-880 series tap range and TSL-470 soap dispenser, this was where we turned. The Splash Lab and the Golden Ratio When installed together, the spout length of either the TSL-881 or TSL-882 sensor tap paired with the TSL-470 soap dispenser align with Leonardo Da Vinci’s golden mean. This creates a naturally harmonious relationship between two proportions and provides a more intuitive hand-washing user journey. Click here for more information or to specify.
