Top 5 Digital Sign Design Rules from the Signworld Team
Rule number 1: Respect the 3×5 rule! Remember, digital messages serve the same purpose as physical signs: they’re there to communicate clear, concise messages to your desired audience. It’s easy to get indulgent and try to use every cool image, GIF file, and emoticon you come across to liven things up, but it’s a mistake! Don’t clutter your site or banner ad with text, and keep the font big to make life easier for mobile users, who make up the majority of online audiences these days. Emphasize your important information, and keep your writing simple and concise. The 3×5 rule is a handy way to keep yourself honest in this regard. The rule states that you will not use more than three lines of text of five words each OR five lines of text of three words each when creating your digital signage.
Rule number 2 – Prioritize contrast. Legibility is going to be your strongest weapon in the fight to capture the attention of a webscrollers, and one of the best ways to do that is to prioritize contrast in your design. Poor contrast is one of the number one problems with illegible signage, and that problem typically centers on color choices. Try to pair a light colored font with a dark background or vice versa. That said, this isn’t always a surefire formula; remember those terrible Geocities pages with neon-green lettering on a black background?
