How to Get Android Screen Size in Pixels and Inches Programmatically

How to Get Android Screen Size in Pixels and Inches Programmatically

Subscribe To My Channel and Get More Great Tutorials

This tutorial describes how to get Android Screen Size in pixels and inches programmatically in android, through the following steps:

1) we create a new project in an android studio with new project wizard and choose empty activity form the wizard in our project.
2) we then go to activity_main.xml file and add three text views, each one for the following values: screen width in pixels, screen height in pixels and screen in inches.
3) then we go to MainActivity.java class and get the three text views.
4) we then create DisplayMetrics object, and use it to get the display metrics of the screen.
5) then we get the screen width, height, inches and then set each one to the textview.
6) Finally we deploy and run the app to the android emulator.


1) DisplayMetrics: as described in the android documentations, is a structure describing general information about a display, such as its size, density, and font scaling.
To access the DisplayMetrics members, initialize an object like this: DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics);
2) Display: as described in the android documentations;
Provides information about the size and density of a logical display.
The display area is described in two different ways.
a- The application display area specifies the part of the display that may contain an application window, excluding the system decorations. The application display area may be smaller than the real display area because the system subtracts the space needed for decor elements such as the status bar. Use the following methods to query the application display area: getSize(Point), getRectSize(Rect) and getMetrics(DisplayMetrics).
b- The real display area specifies the part of the display that contains content including the system decorations. Even so, the real display area may be smaller than the physical size of the display if the window manager is emulating a smaller display using (adb shell wm size). Use the following methods to query the real display area: getRealSize(Point), getRealMetrics(DisplayMetrics).
