Setting the line height to around 150% of the font size is a common guideline in typography for a balanced and readable text layout. This provides enough space between lines to enhance legibility and readability. When the line height is too small, text can appear cramped and difficult to read, while excessive line height can make the text disjointed.
By following this guideline, you strike a good balance that makes the text more visually appealing and easier to consume, especially for prolonged reading tasks. Adjusting line height appropriately can significantly impact the overall look and feel of a block of text, contributing to a more pleasurable reading experience for your audience.
