List of Device PPI
This is an incomplete list of devices' displayed PPI
This is a list of selected devices' displayed pixels per inch. A display device has a limited number of pixels it is able to display, and a limited space over which to display them. The more pixels per inch a device is able to display, the smaller the pixels. On a small portable computer or cell phone, a higher PPI is desirable as these devices are designed to be viewed up close. On a desktop or larger monitor not intended for up viewing up close, however, too high a PPI may result in text being too small to read.
