I recently worked on a project which involved creating a Facebook app using the new Timeline theme for pages.

If you need to customize the width and height of the canvas of your Facebook application then add the the following lines of code:

-Include the Facebook JS library in your app

<script src=”https://connect.facebook.net/en_US/all.js”></script>

-Add this to your HTML body tag if you want

<body style=”overflow: hidden”>

-The “overflow: hidden” will hide the side bars. Omit this if you want the sidebars

FB.init({ appId : '374335755952311', status : true, cookie : true, xfbml : true }); FB.Canvas.setSize({ width: 825, height:1200 });

-“FB.Canvas.setSize({ width: 825, height:1200 })” is what sets the width and height of your page app.
