Check out the size of the iPad Mini compared to other tablets
Although still a rumour this diagram shows us how the new iPad Mini measures up to the Kindle Fire, Nexus 7 and iPad.
The rumoured iPad mini would very probably definitely share the same 4:3 aspect ratio of the current iPad, which (among other reasons) would call for a 7.85-inch screen as opposed to the flat 7-inch screen of the Kindle Fire and Nexus 7. So though in name the iPad Mini might be a “7-inch tablet”, the rumoured dimensions of it have it as nearly 40% larger than 7-inch tablets and two-thirds the size of the original iPad – Gizmodo
