Display size: 7 feet tall x 12 feet wide


Pixel Pitch: 10mm


Pixel Matrix: 210 tall x 360 wide


Artwork Size: 420 pixels tall x 720 pixels wide


60 pixels = 1 foot



  • JPG, BMP or GIF for still image content at 100% quality; Use RGB color, not CMYK.

  • Resolution: 72 dpi is adequate. Because message centers have a fixed pixel spread, DPI is technically irrelevant.

  • Physical size of artwork is also a non-factor. Focus on the actual pixel dimensions (height and width) of the artwork.



The first step to creating effective messages with your electronic sign is to keep the wording short and succinct.

  • Avoid spelling out complete sentences. Don’t use eight words when four will do.

  • Stick with shorter, simple words to maximize quick comprehension by motorists.

  • A single message idea will read quicker and more easily than trying to combine multiple offers.



Large text will allow motorists to see your message from a greater distance. If your text is too small, it will be too hard to read. Your audience is then likely to disregard your messages entirely. Although capable of much smaller, we recommend a 12" character as a minimum.



Avoid using thin fonts as well as most script fonts. The strokes of each character are simply too thin to maintain legibility over long distances. Use thick, heavy fonts to maximize readability. The bold option is an excellent way to add weight to your wording.

High color contrast is a key ingredient. Just like using large text, the right color combination can make your message readable from a much longer distance. Refer to the samples below for many of the best text color vs. background color combinations for your electronic sign.

Avoid White Backgrounds

White backgrounds can be very intense on a digital message board. Each pixel on an LED board consists of a red, a green, and a blue colored diode, and each diode adjusts to create each particular color. A black pixel turns all three colors completely off, while a white pixel has all three colors on at full intensity. This intensity can create hazardous driving conditions, especially after dark. RGB 235, 235, 235 or darker is OK.

Other Guidelines:

  • Artwork must be professionally designed and follow sound design principles

  • No nudity, profanity, graphic violence, hate speech, or personal attacks

  • No political advertisements

  • No advertising for illegal goods or services

  • No statements that are verifiably false or needlessly inflammatory

  • No footnotes, disclaimers, or “fine print” of any kind

  • The identity of the advertiser must be discernible.

  • Arch Digital Community Gateways can reject any content at their discretion.
