By keeping a list view open, you can check the Size column as you move your files into different folders (so you can make sure the folders fit onto a blank CD, for example). For example, you might decide to open the same window twice while doing some hard-drive housekeeping. Using the View menu or the controls in the toolbar, put one of these windows into list view and the other into icon view. Choose File→New Finder Window (⌘-N), and then choose Go→Applications again.
