I'm not referring to changing the size of the font or margin (which actually changes the contents of the document and how it prints), but using the 'View' or 'Zoom' function (which only changes the appearance of the document on-screen). Programs like Microsoft Word have the ability to reduce or enlarge the display of an entire document on your screen without changing how it prints or fits onto each page. Have you ever noticed that when you print out a Microsoft Word document, the size of the text on your computer screen does not match the size on the printout? If your documents seem a bit small on-screen, you can always just choose 125% or 150% to arbitrarily enlarge them on-screen (without changing how they print), but if you have ever wanted them to look the same size on-screen as they look when printed, read on for my advice on how to do this.
