Screen size, resolution and quality are some of the most important features to consider when choosing a smartphone.
Apple iPhone 13 Pro Max's 6.7" OLED LCD is slightly larger (0.6" ) than the Apple iPhone 13's 6.1" OLED screen.
Besides comparing the LCD sizes, another specs that we find useful to compare is the ratio of screen area to total surface area of the phone (screen area/total surface area).
Apple iPhone 13 Pro Max LCD covers 88% of its surface which is only slightly higher then Apple iPhone 13's 87%.
Screen size is only one side of the story, resolution is as important in most cases.
Apple iPhone 13 Pro Max and Apple iPhone 13 have exactly the same pixel density -457ppi- so we don't have a winner here.
