What role does spacing play in the readability of text?

Spacing is crucial for improving comprehension and flow in text because it helps structure the information, making it easier for readers to process the content. Proper spacing between letters (kerning), words, and lines (leading) creates a visually inviting layout that prevents readers from feeling overwhelmed or lost in dense blocks of text. When text is well-spaced, it allows for easier tracking from one line to the next, which is especially important in lengthy paragraphs.

Furthermore, appropriate spacing contributes to the hierarchy of the information presented; it can differentiate headings from body text, creating clear sections that are easily navigable. This enhancement of readability directly impacts how well the reader understands and retains the information.

Other options, while related to design and typography, do not capture the primary significance of spacing in improving how effectively readers engage with text in terms of comprehension and flow.
