How to get the physical size of android's screen programatically in java?

I am coding to find out the pieces of information of the display in android. Something I did to find out the screen height in pixels is:

public static int getScreenHeight() {
return Resources.getSystem().getDisplayMetrics().heightPixels;}

And it's working properly. But I also wanted to get the screen's physical width and height , how do I get this? is it possible? Thanks

The DisplayMetrics class includes all the information you need:

  • widthPixels
  • xdpi

And

  • heightPixels
  • ydpi

These second values correspond to the number of pixels per inch for the physical screen, so you can compute e.g. the width in inches like this:

float widthInches = metrics.widthPixels / metrics.xdpi;
