Abstract:

Children today are reading large amounts of text on computer screens, either in the classroom or for leisure. In fact, currently there is a drive to supplement or even replace some traditional pen and paper lectures and tests with computer-based ones. However, to date there has been no research specific to a younger population investigating preferences for different types and sizes of fonts for reading online. This study sought to address this need by examining four types of fonts at 12- and 14-point sizes in order to help determine the font combination that is perceived as most readable on computer screens and most preferred by children.
