Android emulator - simulate particular device

Perhaps the text on the screenshot is larger because the display size settings on the LG K4 were set to something larger than default. I've run into this error a few times, where an application would look completely different when viewed on different phones of the same size because of this setting.

As far as I know, it is not possible to simulate exact display sizes with the Android Emulator. Also, if it were possible, it would not guarantee looking the same as the actual phone as most manufacturers have custom settings and skins which cannot be replicated by the emulator.
