Large Text Editions are designed for readers that are visually impaired. The user of larger fonts and clearer layouts is required for books in this format.
Typically, a font size of 14-18 point would be considered large print. Anything over 18 point is considered giant print. It’s also best to ensure there is a strong contrast between the print and the background. For example, using light text on a darker background might be easier to read than using dark text on light background.
‘Sans-Serif’ fonts are recommended for Large Text Editions since they are plain and easier to read. Serifs are details on the end of some font strokes that can make the letters harder to distinguish. Fonts that do not include these details are called Sans-Serif fonts.
Below are examples of Serif and Sans-Serif fonts, with some of the serifs circled in red.
