Distance & Visibility - Sign Letter Height & Best Colors

One of the most important consideration when designing signage is readability at specific distances. Since signage is created to inform and direct the viewer - a clear and easy to read message is essential. Here are some helpful hints in creating an effective sign design;

  • Keep the layout clean and information concise.
  • Size your fonts based on typical viewing distance (see below).
  • Avoid hard to read typefaces like script, light-weight, and heavily compressed fonts.
  • Use background colors that contrast the text.
  • Avoid backgrounds that distract from the text.
  • Test the readability of your design by printing it out at small scale and viewing it from a distance proportionate the finished product.
