How to get Device height and width in Xamarin forms?

Android then you should use the pixels — you don’t need units.

1. var scale = Resources.DisplayMetrics.Density;//density i.e., pixels per inch or cms.
2. var width = (double)((widthPixels – 0.5f) / scale);//width in units.
3. var heightPixels = Resources.DisplayMetrics.HeightPixels;////getting the height in pixels.

Solution:

1. Update: You can use Xamarin. Essentials nuget package for this and many other purposes. var width = DeviceDisplay.
2. Old answer: There is an easy way to get the screen’s width and height in Xamarin.
3. Create two public members in your App. cs:
4. Set the values in your MainActivity. cs (Android) or your AppDelegate.

Get started with Visual Studio 2019

1. Launch Visual Studio 2019, and in the start window click Create a new project to create a new project:
2. In the Create a new project window, select Mobile in the Project type drop-down, select the Mobile App (Xamarin.Forms) template, and click the Next button:

For Xamarin.Forms in Android, we get the width and height values in pixels. To get the exact size of the screen we have to get the pixel density and on dividing the pixels with density we get the length and breadth of the screen in units and we use these units to set the sizes of the views of Xamarin.Forms.

If you have an Android virtual device, run the app on it, else connect your Android phone and run the app on it. Simply, connect your phone and go to Visual Studio. The connected phone will show up in the Run menu. (Ex:LENOVO A6020a40 (Android 5.1-API 22)).

In summary, a Xamarin.Forms programmer targeting phones and tablets can assume that all units of measurement are based on the following criterion: The read-only Width and Height properties defined by VisualElement have default “mock” values of –1.

So App.ScreenHeight and App.ScreenWidth will be initialized when the App will be launched, then you will be able to use them anywhere in the common code. You can use the Width property when you are in a ContentPage. For example, Note that this is set during the Layout phase. So, you can only use it after the page is initialized, otherwise it is -1.
