the width of the content window depends on the width of the web browser window of whoever is viewing the page. It can be one of these values.

You can try to scale down your browser window and see how the content area is getting smaller.

Basically you should make a temporary 1240 pixels wide stripe in the middle (just in the image editor) and place whatever you want to be on the sides around it. This ensures that it won't be covered by the content.
