new product listing problem

hi, Im new to these kind of stuff and I have a problem. How can I increase the size of the boxes in the new listing area? I dont want to reduce the size of my images just to fit in the boxes because its too hard to see the prints on the shirts. You can see the problem here: http://shop.elegancepiece.com/. I thank you in advance for anyone who can help.

look for #navMainWrapper in your stylesheet.css file and change the width to something like 950px; This should help.

thanks for the quick response. I tried doing as you said but it didnt seem to change anything. I edited the stylesheet.css of the custom template Im currently using.

The #mainWrapper of your current template is set to 820px. Make sure you're editing the right file, and that the permissions allow you to change that file.
