How big is 1800 pixels?

The size of 1800 pixels depends on the context in which it is used, such as the dimensions of an image or screen resolution. For example, an image that is 1800 pixels wide could be displayed as a long rectangle on a screen, while a square image might be 1800 x 1800 pixels. In terms of print, the physical size also depends on the DPI (dots per inch) setting; at 300 DPI, 1800 pixels would equal 6 inches.
