In picking the best size for LED signs, one must understand the importance of Viewing Distance, Character Height, Pixel Matrix and Resolution (or Pitch) to better help you decide.
The most important factor when choosing the size of open signs made of LED is the viewing distance . Not only is the actual distance between the viewer and the sign important, but it should be considered how the target audience views the display. Note whether the target audience is walking, standing, or driving by as this will help you decide what open signs to choose.
Character height is the height of each character in your led sign display. The rule of thumb is that the height of each character or letter should be 1” for every 30 feet of viewing distance. The maximum acceptable distance is 50 feet for every inch of letter height. For example, if the led signs are to be mounted on a highway with 600 feet from vehicles passing at 55 mph, the character height should be 20” tall.
Pixel matrix determines how many lines and how many characters per line can the led signs display. This is crucial because this determines how your target audience can read the messages you want to display. In other words, a 16x80 pixel matrix means 16 rows of vertical pixels and 80 rows of horizontal pixels.
Because clarity is important for your target audience to understand your message, make sure that the resolution is high enough so the viewers can clearly read the led signs. Resolution greatly affects the price of the led signs, which means that the higher resolution would cost more. This is because higher resolution means more diodes and more circuits.
These are just a few factors to consider when purchasing LED signs. Always remember that led signs are cheaper in the long run because not only are programmable signs being manufactured nowadays, but LED signs are energy saving and longer lasting too.
