The great typography bake-off: comparing legibility at-a-glance.

Area of Science:

• Human-Computer Interaction
• Applied Psychology
• Graphic Design

Background:

• Digital interfaces increasingly rely on typography for information delivery.
• Designers face numerous sans-serif typeface choices for dynamic interfaces.
• Optimizing legibility for glanceable information is crucial in mobile and safety-critical contexts.

Purpose of the Study:

• To compare the glance-based legibility of eight popular sans-serif typefaces.
• To provide a scientific method for evaluating font legibility under time pressure.
• To offer actionable data for designing user-friendly, glanceable interfaces.

Main Methods:

• An experiment was conducted to assess glance-based legibility.
• Eight popular sans-serif typefaces were evaluated using a 'bake-off' method.
• The study focused on time-pressure scenarios common in mobile and automotive interfaces.

Main Results:

• Significant differences in glance-based legibility were found among the tested typefaces.
• Typography choice impacts usability, particularly in safety-critical applications.
• The results highlight the importance of font selection beyond aesthetic preference.

Conclusions:

• A validated method for assessing glanceable typeface legibility is presented.
• Actionable insights guide the selection of typefaces for optimized usability.
• Font choice is a critical factor for effective information consumption in fast-paced digital environments.
