How to increase the view size of email list..

My boss asked me if there is a way to increase the size of the Inbox area where you can arrange by date, conversation, size, etc..not the preview area for individual emails. He knows how to use the ctrl + wheel mouse to increase that..but he wants the actual list of tge emails to be larger. He basically wants the From and Subject to be larger..is this possible without changing the screen resolution?

This is for Outlook 2007.
