The iPad Mini 2 has the same sized 7.9-inch screen, and largely the same design as, the first generation iPad Mini (1st generation). One notable change is the inclusion of a Retina Display, matching the screen resolution of the full-sized Retina iPad models. As the Mini 2 features the same resolution as the iPad Air, this makes the Mini 2's screen even more pixel dense compared to its larger sibling.
Based on the above text, what's the best answer to this question: is ipad mini the same size as ipad mini 2?
yes
