Since the 1930s, media violence has appeared on screens of increasingly varying shapes and sizes. Violent content can now be seen in formats ranging from a gigantic IMAX movie to a tiny mobile smartphone game. Consuming violent content in these diverse forms has the potential to differentially shape audience responses. This entry presents a brief overview of screen size as a media technology variable. It then reviews research findings on the effects of screen size and concludes with theoretical considerations for media violence effects as a function of screen size.

Screen Size as a Media Technology Variable

The early 1930s Payne Fund studies on the content of motion pictures called attention to the amount of violence in big-screen movies. Since that time, screen sizes have gotten both smaller and larger. The wide diffusion of television in the 1950s brought smaller-screen violent content into homes, and the motion picture industry responded by introducing larger-screen formats such as Cinerama and, more recently, IMAX, which has a standard screen size of 72 × 52.8 feet. The increase in movie screen sizes has been paralleled by a steady increase in television screen sizes, with Japanese electronics manufacturer Sharp predicting the average television to be 60 inches by 2015. At the same time, screens are also getting smaller. Violent content is now being consumed on handheld gaming systems and mobile devices such as the Apple iPhone, which has a 3.5-inch screen.

Screen sizes clearly vary more than ever, but a consideration of screen size must also factor in other aspects of screen technology. First, the width of screens has changed over time. The classic movie and television aspect ratio was 4:3 (meaning 4 units wide by 3 units high). Now, most movies have an aspect ratio of either 1.85:1 or 2.35:1, and high-definition television (HDTV) sets have an aspect ratio of 16:9. In both cases, the result is a wider screen than in the past. Second, viewing distance affects how screen size is perceived. A small screen placed directly in front of a viewer’s eyes, as it might be when the viewer wears a head-mounted display (HMD), may appear to be enormous, while a large screen viewed from far away may appear small. Viewing distance calculators, accessible online, exist to help determine the optimal viewing distance for various sizes of screens. A third consideration is screen resolution. As screen size increases, image quality may appear worse, especially when viewed at close distance. This has become less of an issue, however, with newer high-definition formats than it was with standard-definition television.

Research on the Effects of Screen Size

Screen size effects have been the subject of numerous investigations. In a review of the literature on television screen size, Cheryl Campanella Bracken and Renee Botta (2010) noted that it is the most commonly studied television form variable, with experiments dating back to the early 1970s and peaking in the 1990s. Generally, larger screen sizes have been shown to intensify reactions to content. Specific outcomes of large-screen viewing identified by Bracken and Botta include increased attention, arousal, dizziness, enjoyment, and telepresence (the sense of “being there” in the media environment). Research also has shown that screen size affects receiver perceptions of objects on the screen, with mixed findings. Larger screens have been shown to lead to both more and less favorable evaluations of people on the screen, for example.
