The system, method and program of the invention enables a presentation authoring tool, that is used to create presentation data for later projection, to determine a recommended font size for the created presentation data displayed on a display screen of a computer executing the presentation authoring tool. The user interface presents a display screen for receiving input of an expected viewing distance for the later projection of the presentation. The recommended font is determined based upon the expected viewing distance of the later projection having a projected font size viewable by a person, having a certain vision capability, at the expected viewing distance. The expected viewing distance may be a maximum viewing distance or a room depth of a room in which the later projection takes place.
