Legibility over Readability: A Study

Sub-Section 1: Line Height

When it comes to legibility, line height is a crucial factor. A line height that is too short can make text feel cramped, while one that is too long can make it look sparse. But have you ever wondered what the ideal line height is?

According to our research, the ideal line height is between 1.2 and 1.5 times the font size. This means that if your font size is 16px, your line height should be between 19.2px and 24px.

Sub-Section 2: Letter Spacing

Letter spacing, or letter kerning, is another crucial factor in legibility. A well-spaced font can make text look clean and organized, while a poorly spaced font can look cluttered and confusing.

Our research suggests that an average letter spacing of 0.05em to 0.1em is optimal for most fonts.
