The Golden Ratio

  1. Have you ever looked at signage and thought that sign looks great, or it looks less then great?
  2. When it comes to designing signs, we want them to look the best. An often-overlooked rule when designing signs is the Golden ratio.
Mathematical equation for the golden ratio.
  • Mathematically, the Golden Ratio proportioning is “A+B is to A as A is to B” with an approximate value of 1.618. This is the key number to remember. With design, multiply any element’s size x 1.618 to determine the size of another, proportionally balanced element.
  • For example, if the height of an object is 5 inches to calculate the length = 1.618 x 5 to determine the length of 8.09 inches.
  • If we take the length and divide 8.09 by 5, we get the golden radio of 1.618 knowing our signage is fits the golden ratio.
  • This also works on sign lettering. If our main letters are 5/8 our sub letters are .625/1.618 = .386 or more common .375 or 3/8
  • A square sign on 4×4, looks a little plain, but when we have a sign that fits the golden radio, it appears more visually appealing.
  • When we need the long side, we multiply by 1.618
Square sign on the left, sign on the right design with the golden ratio.

The sign on the left is a typical square sign, while the sign on the right adheres to both text rules and sign size rules of the golden ratio.
