Pixels have no size until you choose a DPI
An image of 4000 × 3000 pixels is 12 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: 4000 ÷ 300 = 13.33 inches wide at 300 DPI. On a screen the DPI stored in the file is ignored; the image takes up 4000 × 3000 of the screen’s own pixels.
