A typeface is a designed set of characters, such as Arial or Times New Roman. A font is a specific typeface setting, such as Arial 14-point bold.
While there is no designated "best" font for accessibility, applying good design principles usually aids in making digital content accessible to most readers:
- Simple is usually best - using simple, easily-recognized fonts supports readability.
- Avoid using too many variations of typefaces or fonts in a single document, webpage or presentation.
- Make sure there is appropriate contrast between the font and background.
