How do you make documents legible?

To make documents legible, use a clear and simple font, such as Arial or Times New Roman, with a font size of at least 12 points. Ensure sufficient contrast between the text and background colors, and use adequate spacing between lines and paragraphs. Organize content with headings and bullet points for easier navigation, and avoid overly complex language to enhance understanding. Lastly, proofread for clarity and errors to ensure a polished final document.
