Digital Signage Design Tips
Contrast And Legibility
The 3 X 5 Rule
Sometimes less is more. Be brief and concise. Don’t fill the screen with meaningless content. Let the text be large enough and only contain the most valuable information. As rule of the thumb, have at most 3 lines each with 5 words, or 5 lines with 3 words each.
Be careful which fonts are used. Italic fonts should be sparingly used because they can be hard to decipher even in close-up view. You can improve your content legibility by using large text with bold lettering. Arial font is an easy to read font recommended for short texts.
