OK....I see you're using the 50s Dinner template in the example. I assume the problem your describing is the margins are pulled-in so text area is alot smaller than normal.
I just switched one of mine to test, and my standard text didn't do similar. Does it do that with the one-page lister Preview for you?
Why is the background behind the text in each section yellow? That's not part of the template and suggests some adds to the formating. Was the code a cut-and-paste?
Just as a suggestion to reduce length, have you tried the Thumbnail arrangement for the pictures? With thumbnail, you get a regular size pic that changes as you "hover" the cursor over each thumbnail. Here's an example from one of my recently ended auctions:
