I want to use Word to create a coil bound booklet. I want the booklet to be the size of a page in Landscape mode divided into two columns.

My question is what size should I set each column to be? Is there a preset in Word for this? I use Word 2010.

I also plan on printing double sided pages. I have no idea how this works - is there a tutorial on creating and printing landscape, half page, double sided for a booklet?

Thanks.
