“Imagine coffee being poured into a cup. If the cup is filled to the very top, it is difficult to avoid spilling it on yourself as you take the first sip.” (5, White) This space is that little bit of room at the top of your coffee cup that makes it manageable. The author talks about the underuse of white space to be overwhelming, you will spill it on yourself. The eye is attracted to space that lets you relax while picking up the intended message. Too much of the message can be jumbled and hard to understand.
This can be seen all around us. An example they gave in the article is a news paper. When you are reading a newspaper or a book there is a lot of white space:the space between the lines, the space in the margins, if a book was edge to edge text with no room, it would overwhelm the reader even if it is the same book. We see this in adds too, simplicity is more attractive to an audience then a jumble. Many ads have space around minimal words to get the point across without being too much. The goal is to attract the audience without overwhelming them.
