Some companies are capable of producing their own signage content while others rely on outside design agencies. Whatever you choose, make sure that your digital content demands attention and creates an impact. 

This is why you should never underestimate or ignore the value of creating content. Your business depends on it and your viewers demand it. Make your content delivery your brand's story, move your viewers and your business into an entirely new dimension. 

Understanding Letter Case and Shapes 

Text plays a huge factor into how viewers can receive and absorb the information in your digital content. 

Words in ALL CAPS are in fact the most difficult to read and understand.  Several studies prove that all caps are less readable than lower-case text. 

According to the New York Post:

"Studies have shown that it is harder to read all-caps signs, and those extra milliseconds spent staring away from the road have been shown to increase the likelihood of accidents, particularly among older drivers." 

Also, the Federal Highway Administration states that switching from all caps to a combination of upper and lowercase improves safety as motorists find it easier to improve signs in lower case.(Source:

People are more familiar with sentence case as opposed to all caps.  If you take a look a LED sign with all caps content, you can see how hard it is to read the message. 

Readability is more than reading. Letters when combined form a certain shape. All words have that distinctive shape. That is how people read. As we recognize the certain pattern of letter shapes, we can get to understand the word. 

This makes it easier to recognize words from the shape they make that reading it while travelling or passing by.

When to use all caps? 

All caps are great to use in logos, acronyms, and abbreviations. With LED signs, use uppercase only to give emphasis to your content. In fact, most designers rarely use that Caps Lock key. 

Best Strategy for Outdoor LED Sign Messages

Remember that the main function of a outdoor LED sign is to communicate your message to your viewers. Typography can make or break your LED sign. There's no point of displaying a message if no one can read and understand it in the first place, right. 

The next time you create a new content for your LED Sign, test it out before you roll it. Has someone take a look at the digital signage and see if they can remember your message. 

The key here is to try a combination of uppercase and lowercase letters to make your content more legible. 

Relevant, engaging and dynamic content is essential for displaying good engaging messages on a outdoor LED sign. It begins and ends with content guidelines and a strategy that reflects your brand's marketing objectives. 

Ensure that your words create an impact and can get your message across.
