### Remarks

An EditorWindow can be resized.  The [EditorWindow.maxSize](/engine/6000.5/script-reference/unityeditor/editorwindow/maxsize.md) variable provides the largest width and height that is supported.  This is typically a Vector2(4000,4000). Note that this size is likely to be larger than most screen resolutions.
