What should be avoided in personal communication formats for clarity?

Justified text should be avoided in personal communication formats for clarity because it can create uneven spacing between words, making it visually harder for readers to follow along. In justified text, the text is aligned to both the left and right margins, resulting in varying amounts of space between words to fill the line. This often leads to a "rivers of white" effect, where gaps appear in the text, which can disrupt the reading flow and comprehension.

In contrast, left-aligned or unjustified text maintains consistent spacing between words, providing a more natural reading experience. Short lines enhance readability by preventing the reader’s eye from wandering too far across the page, and warm designs can create an inviting and friendly atmosphere in communication. These formats help ensure that the message is easily understood, which is the goal in effective personal communication.
