# What are the proportions of the golden rectangle?

Golden Rectangle. In geometry, a golden rectangle is one whose side lengths are in the golden ratio (approximately 1:1.618).

### What is the golden ratio in math?

The Golden ratio is a special number found by dividing a line into two parts so that the longer part divided by the smaller part is also equal to the whole length divided by the longer part. It is often symbolized using phi, after the 21st letter of the Greek alphabet. Phi is usually rounded off to 1.618.
• #### What mathematicians discovered the golden ratio?

Throughout history, the ratio for length to width of rectangles of 1.61803 39887 49894 84820 has been considered the most pleasing to the eye. This ratio was named the golden ratio by the Greeks. In the world of mathematics, the numeric value is called "phi", named for the Greek sculptor Phidias.
• #### What is the golden mean in photography?

The Golden Ratio In Photography. Some argue that the rule of thirds is an oversimplification of a more advanced mathematical equation known as the golden ratio (also known as the golden mean). The golden ratio is a ratio which has continued to surprise artists, scientists, musicians and mathematicians for centuries.
• #### What is the golden angle?

The golden angle is the angle subtended by the smaller (red) arc when two arcs that make up a circle are in the golden ratio.

### What is the golden rectangle in design?

There's a common mathematical ratio found in nature that can be used to create pleasing, natural looking compositions in your design work. We call it the Golden Ratio, although it's also known as the Golden Mean, The Golden Section, or the Greek letter phi.
• #### What is the rule of thirds in art?

The Rule of Thirds is actually a guideline more than a rule. It is intended to help the artist with the placement of the elements and focal point within the composition. But, if you want your viewer to ignore the other parts of your painting, then go ahead break a rule and center your subject like a big bull's-eye!
• #### What is the rule of thirds in film?

The rule of thirds is a concept in video and film production in which the frame is divided into into nine imaginary sections, as illustrated on the right. This creates reference points which act as guides for framing the image.
• #### What is cutting on action?

Cutting on action or matching on action refers to film editing and video editing techniques where the editor cuts from one shot to another view that matches the first shot's action.

### What is the golden rectangle in art?

There's a mathematical ratio commonly found in nature—the ratio of 1 to 1.618—that has many names. Most often we call it the Golden Section, Golden Ratio, or Golden Mean, but it's also occasionally referred to as the Golden Number, Divine Proportion, Golden Proportion, Fibonacci Number, and Phi.
• #### What is the golden mean in photography?

The Golden Ratio In Photography. Some argue that the rule of thirds is an oversimplification of a more advanced mathematical equation known as the golden ratio (also known as the golden mean). The golden ratio is a ratio which has continued to surprise artists, scientists, musicians and mathematicians for centuries.
• #### What is the symbol for the golden ratio?

Édouard Lucas (1842–1891) gives the numerical sequence now known as the Fibonacci sequence its present name. Mark Barr (20th century) suggests the Greek letter phi (φ), the initial letter of Greek sculptor Phidias's name, as a symbol for the golden ratio.
• #### How was the golden ratio found?

The Greeks are thought by some to have based the design of the Parthenon on this proportion, but this is subject to some conjecture. Phidias (500 BC – 432 BC), a Greek sculptor and mathematician, studied phi and applied it to the design of sculptures for the Parthenon.
