So, as you can see from the size comparison image and specs above, Apple’s all-new iPhone 12 mini is physically smaller than the iPhone SE (2nd generation), but a tad larger than the iPhone SE (first generation). The display sizes obviously range greatly, from the SE 1’s 4.0-inch display to the SE 2’s 4.7-inch to the iPhone 12 mini’s 5.4-inch, while all retaining a relatively small physical enclosure (thanks to the jettisoning of the antiquated Home button in the iPhone 12 mini).
