Pixels have no size until you choose a DPI
An image of 2048 × 1536 pixels is 3.1 million dots of colour and nothing more. It only gets a size in inches when it is printed, and that size is the pixels divided by the resolution: 2048 ÷ 300 = 6.83 inches wide at 300 DPI. On a screen the DPI stored in the file is ignored; the image takes up 2048 × 1536 of the screen’s own pixels.
