Abstract

A method of displaying pages of information on an electronic screen may include receiving a first page of information including first text, and rendering the first page of information including the first text on the electronic screen at a first zoom setting. After rendering the first page of information at the first zoom setting, zoom input may be accepted from a user through a user interface, and the first page of information including the first text may be rendered on the electronic screen at a second zoom setting different than the first zoom setting responsive to the zoom input. In addition, a target text size may be saved in electronic memory, and the target text size may represent a size of the first text on the electronic screen at the second zoom setting. A second page of information including second text different than the first text may be received, and a third zoom setting may be determined responsive to the target text size and responsive to the second text. The second page of information including the second text may then be rendered on the electronic screen at a third zoom setting. Related devices and computer program products are also discussed.
