| | Pixels per inch - Wikipedia, the free encyclopedia |
 | | Pixels per inch (PPI) or pixel density is a measurement of the resolution of a computer display, related to the size of the display in inches and the total number of pixels in the horizontal and vertical directions. |
 | | This measurement is often referred to as dots per inch, though that measurement more accurately refers to the resolution of a computer printer. |
 | | For example, a display that is 11 inches wide by 8.5 inches high, capable of a maximum 1024 by 768 pixel resolution, can display about 93 PPI in both the horizontal and vertical directions. |
