Change project size in wordpress

I'm displaying my project within a Wordpress page, the player seems to have defaulted to a certain size on the page, there is room for it to display larger.

How can I change this? the export oresolution is 1024 x768/

Do I add code around where I embed it?

[WP_UnityObject src="http://www.renderjug.com/wp-admin/images/theisland.unity3d" /]

 

Thanks to Tempest and Canowar in the unity chat room I have got the answer to this, basically do the following

Code (csharp):

1.  
2. [WP_UnityObject src="http://www.renderjug.com/wp-admin/images/theisland.unity3d" width="700" height="600"/]
3.  
4.
