The line height recommended by classic typography books is 130-150% of line height, depending on the typeface and personal preference. I've also read web typography tutorials giving the same recommendation. IMHO, the default line height in browsers is just too narrow. Agreed, though, that it's a matter of what you're used to. But when you're used to high quality typography designed to make the text easy to read, you tend to notice the mistakes. Here are some rules I go by: - Use an appropriate font designed for screen display - Avoid small font sizes: 16px is a good default, less than 14px is usually too small - Use dark text on light background - Typeset on a vertical grid with 130-150% of line height - Use a reasonable line length (no more than 80 characters) All these rules aim to make the text easy to read and easy on the eyes.
