Documents with white space in the margins and between paragraphs are the easiest to read. Text that is justified and aligned on both the right and left margins might make a document difficult to read. The terms "justified text" and "centered text" refer to the same text type. Both styles are equally acceptable. Text that is left-aligned (not common) or right-aligned (even less common) is called "tightly spaced text." These types of texts are difficult to read because there is not much room between the words or between each word and the margin. They are used when space is at a premium. Tightly spaced text should be avoided if possible. It is easier to read regular-spaced text where there is plenty of space between each word and the margin. This style of writing allows you to express yourself clearly without using too many words or leaving out important details. Regular-spaced text is used when accuracy is important. For example, a dictionary defines a word as regularly spaced text. Because we want to use accurate definitions, we choose this style of writing. Now that we know how to write accurately, let's see how to write effectively.
