One of the principles of design, white space is the absence of text and graphics. White space provides visual breathing room for the eye. White space is more than just large empty places on the page, it's also the overall airiness or density of the page including space between lines of type (leading), text offset around graphics, size of margins, and heaviness or lightness of the fonts.

"Achieve a balance of ink and white space using a mix of techniques... as appropriate to your design." — How to Add White Space to a Layout
"The most prominent white space in a design is the margins all around the page." — Using Margins in Desktop Publishing
"Is there such a thing as too much white space? Yes, there is. However, it's rarely the case in the work done by non-designers and those new to desktop publishing. Usually we try to cram too much onto the page, afraid that we'll leave out something important." — Use More White Space
"Avoiding pages of gray text usually involves injecting more white space and contrast into the text." — Gray Text
