On Google+, personal profiles and business Pages share identical layouts, so the cover photo image sizes are universal. Furthermore, Google+ users need to understand where and how their cover photo is displayed. In addition to appearing above their profile, it also appears anytime their Google+ username appears within Google+ and someone hovers over that name. The resulting popup is referred to as your "Hovercard" and includes your cover photo, profile image, name and a few other pieces of information. As Stephan Hovnanian puts it, "your hovercard becomes a digital business card across that entire social network."
