Size of iOS device

iOS devices are available in two statistical units: pixels and dots, and for programmers, just remember the dots.

Dimensions of common iOS devices (dots)

Resolution (DOTS)	Equipment	Resolution (pixels)
320*480	4, 4s	320*480 (4) 640*940 (4s)
320*568	5, 5s	640*1136 (5) 640*1136 (5s)
375*667	6, 6s	750*1334 (6) 750*1334 (6s)
414*736	6p, 6ps	1080*1920 (6p) 1080*1920 (6PS)

The scaling factor for iPhone4 is 1,iphone 6p and IPhone 6ps scaling factor is 2.60, but on the program we assume that the scaling factor is 3, and the scaling factor for other devices is 2.
