Not surprisingly, the iPhone 12 Pro Max is the larger of the two devices in our comparison, with 6.7 inches of display space. That’s actually a bit larger than its immediate predecessor in the iPhone lineup, the iPhone 11 Pro Max, which came with a 6.5-inch display. But the iPhone 12 Pro has gotten a bump on display size, too, measuring in at 6.1 inches (that’s up from the 5.8-inch iPhone 11 Pro). The gulf in display sizes is certainly the largest differentiator in our iPhone 12 Pro vs Pro Max comparison—that makes the 12 Pro Max a full 10 percent larger than the 12 Pro. And of course, it’s the probably the main thing that will affect a buying decision between the two phones. Otherwise, the displays are similar—with the same vibrant OLED Retina display technology and same resolution (in pixels-per-inch) on both phones--460 ppi for the 12 Pro and 458 ppi for the 12 Pro Max.
As mentioned, Apple has redesigned the form factor for the iPhone 12 lineup. That switches the iPhone 12 Pro and Pro Max to a flat-edge design. The phones are thus boxier than the iPhones of recent generations--which had featured a curved-edge design since the iPhone 6 in 2014. The redesign also removes the border that used to separate the display and the stainless-steel body--enabling the aluminum enclosure and glass to stay flush on both phones.
