At first i am confused when Google says to use dp units for icon shadows. Confusing really.

For your information I would like to mention that the HDPI resolution is 480×854 or 480×800

The screen sizes I’ve used are based on popular devices, and screen manufactures don’t follow the rules. Also, you can have a mobile handset screen (e.g. 640 x 960) and a tablet screen (e.g. 1536 x 2048) and they both use the same density of images.

If this is the calculation for screen size

XXHDPI – 300% – x3.o
XHDPI – 200% – x2.o
HDPI – 150% – x1.5
MDPI – 100% – x1.0

then the screen size should be

320 x 480 – MDPI
480 x 720 – HDPI
640 x 960 – XHDPI
960 x 1440 – XXHDPI

How come the screen resoulution comparison is diffrent above.

Pls guide i am confused.

You’re not the first to notice that, and I don’t know what I was thinking, but if you look at the icons at the top, you’ll see the 480×960 screen has the same icon size as the XHDPI 720 x 1280 screen – so I think I was making the point that even small hand set screen sizes can still have @2x resolution – such as the iPhone for instance.

Although, to be honest, it’s been a while since I made that graphic!

I think there´s a mistake in your “Android screen resolution comparison”, you have repeated the XHDPI density, so if I’m not wrong 480X960 px must be just HDPI density. Beside that it’s a very educational article, thanks.
