The five iPad models, iPad Air, iPad Air 2, iPad mini 2, iPad mini 4, and iPad Pro, require different cases as they come in different screen sizes.
You need a case when you are buying something in breakable glass and scratchable, dentable aluminum for anything from $270 and $1,080, and when out-of-warranty screen repair costs up to $600.
The best case for iPad Air 2: Apple Smart Case (sleek leather folio, multiple color options, do well in both viewing and typing orientations.)
The second best case for iPad Air 2: CaseCrown Omni (priced obviously lower than Apple's cases)
The best case for iPad mini 4 pick: KHOMO Dual Case (simple, affordable)
The best case for the 9.7-inch iPad Pro: MoKo Ultra Slim for 9.7-inch iPad Pro
The best case for the 12.9-inch iPad Pro: MoKo Ultra Slim for 12.9-inch iPad Pro
The best case for a 9.7-inch iPad Pro and an Apple Pencil: iVapo Slim Folio Case for 9.7-inch iPad Pro
The best case for a 12.9-inch iPad Pro and an Apple Pencil: iVapo Slim Folio Case for 12.9-inch iPad Pro
