> The default horizontal size of the Android Player window in pixels.

## Definition

* **Namespace:** [UnityEditor](/engine/6000.7/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

On Android phones and tablets that support multiple windows, this controls the width of the window when in the popup window mode.

### Examples

```csharp
using UnityEngine;
using UnityEditor;
using UnityEditor.Build;

public class DefaultWindowWidthSample : MonoBehaviour
{
    [MenuItem("Build/Default Window width Sample")]
    public static void BuildWindowWidthSample()
    {
        PlayerSettings.SetScriptingBackend(NamedBuildTarget.Android, ScriptingImplementation.IL2CPP);
        PlayerSettings.Android.targetArchitectures = AndroidArchitecture.ARM64;

        //Set default window width
        PlayerSettings.Android.defaultWindowWidth = 100;

        BuildPlayerOptions options = new BuildPlayerOptions();
        options.scenes = new[] { "Assets/Scenes/SampleScene.unity" };
        options.locationPathName = "Build/AndroidBuild.apk";
        options.target = BuildTarget.Android;
        options.targetGroup = BuildTargetGroup.Android;
        BuildPipeline.BuildPlayer(options);
    }
}
```
