Android Screen Resolutions and Their Smallest Width in DP

Standard

Edit: Here a more accurate list provided by Google:  https://design.google.com/devices/

When I was developing with the Genymotion emulator, I had trouble getting a sense of how big the actual devices actually were when choosing resolution size for debugging. So I did a little test to see what their smallest width was in dp for each resolution.

A dp is a density-independent pixel that corresponds to the physical size of a pixel at 160 dpi.

Resolution and DP

Now if I want to test out a resolution, I can just look at this chart and see it’s physical size.

I’ve also added annotations for which devices are small, not long, and long, because I feel those devices are the gotchas and need their own dimens.xml file to make them look good.
