Blog Layout Question

Hi all, I want to be able to use a full page layout on a Wix standard page, with information from my blog.

I have set up categories so that I can then choose what goes on a page, which works fine, the issue is the layout. I would like the blog post to take up the whole page, rather than there being a part of the post, which then needs to be clicked into to read. Am I missing something, I would expected the one column to do this, but sadly not. Is this possible? Many thanks.
