Determining how your prospective audience will view your LED sign is key in determining the right LED sign for YOUR location. Will your potential customer be walking or driving by? How quickly will they be moving?
Determining Maximum Viewing Distance
Estimate one inch of character height for every fifty feet of viewing distance to determine the best character size for your location.
Example: 2? text is readable to about 100 feet.
This is considered a general rule of thumb in determining the overall size for a specific application. Other conditions that may effect viewing distance include surrounding buildings or trees, varying traffic patterns, weather, etc.
Messages viewed from an automobile should be 18? in character height if traffic is moving 35 miles per hour. A 12? character is recommended if traffic is stopped. Clear visibility also depends on distance. You can read a 6? high character from as far away as 300?, if you are not moving. The same size character may be more difficult to read from that distance if you’re driving or moving quickly. .
