Examples
Line Length
Recommended line length is 50-75 characters. Keeping your text box to a width of 500 pixels will ensure optimal readibilty.
- Too wide – if a line of text is too long the reader’s eyes will have a hard time focusing on the text.
- Too narrow – if a line is too short the eye will have to travel back too often, breaking the reader’s rhythm.
Baseline
Weights and styles are an important UX element. Bold and italic help readers to see structure and to skim the text more efficiently. Use font weight to call out the most important information.
