How to calculate the Golden Ratio?

The Golden Ratio, often denoted by the Greek letter Phi (Φ), is a special number approximately equal to 1.618. It appears frequently in geometry, art, architecture, and nature. It is defined when a line segment is divided into two parts such that the ratio of the whole segment to the longer part is equal to the ratio of the longer part to the shorter part.

The fundamental relationship is: (a + b) / a = a / b = Φ

Using the Golden Ratio Calculator: An Example

Let's say you have a shorter segment (b) with a length of 10 units, and you want to find the longer segment (a) and the total length (a+b) that maintain the Golden Ratio.

Step-by-step calculation:

  1. Input: Shorter Segment (b) = 10
  2. Calculate Longer Segment (a): a = b * Φ = 10 * 1.6180339887 ≈ 16.18
  3. Calculate Total Length (a+b): a + b = 16.18 + 10 = 26.18
  4. Result: The longer segment (a) is approximately 16.18 units, and the total length (a+b) is approximately 26.18 units.
