The iPad Mini is 7.87 inches high and 5.3 inches wide with a depth of 0.28 of an inch. It weighs 0.68 pounds for the Wi-Fi version and 0.69 pounds for the 4G version. By way of comparison, the full-sized iPad is 9.5 inches high, 7.31 inches wide and 0.37 inches thick. It also weighs over twice as month, with the newest iPad weighing 1.44 pounds for the Wi-Fi version.
The iPad Mini's screen is 7.9 inches measured at a diagonal. This might sound like just a small bump from the 7-inch tablets, but that extra .9 of an inch constitutes around 35% more viewable space (29.6 square inches verses the 21.9 square inches of a normal 7-inch tablet).
The larger iPad is designed with a comfortable bezel surrounding the screen that easily fits a thumb, which means you can hold it in two hands without covering any part of the display. The iPad Mini is designed to be held with one hand, and as such, the bezel thins at the sides in order to produce a smaller tablet. But when held in landscape mode, there is still plenty of room for the thumbs to rest at the side of the screen without obstructing the view.
