Android DPI Density – What is it?

Screen density is the ratio of the display resolution and the display size, which is quantified as dots per inch, or dpi. The higher the dpi, the smaller each individual pixel is, and hence, the greater the clarity. To put it simply, a higher dpi setting means more detail is displayed per inch but does not necessarily correlate with a higher screen resolution.

Screen density is a ratio of resolution and the display size, and both factors contribute to the density.

For example, the Galaxy Nexus (4.65″ diagonal) has a resolution of 720×1280 px, while the Nexus 7 (7″ diagonal) has a resolution of 800×1280. It is a common misconception to assume that they have about the same screen density since their resolutions are almost identical. However, the Galaxy Nexus has a screen density of about 316 dpi and the Nexus 7 has a screen density of 216 dpi. Why, you ask? This is because they are displaying the same resolution in different amounts of space.
