The larger the better?

Huang, Wang, and Chan studied links between image sizes on packages and evaluations of the contents of those packages; their findings can probably be applicable more broadly: “larger (vs. smaller) food images on food packages can positively influence consumers’ initial product attitudes toward the food (i.e., purchase likelihood). . . . Compared with smaller food images, larger ones improve purchase likelihood. . . . this effect is only observed for vice (vs. virtue) foods.”
