[OS X TeX] Trim size, 6 by 9, for book manuscript

[Toke Knudsen]

Hi all,

My book manuscript is almost complete, but the publisher tells me that the book is supposed to be sized to a 6-by-9 trim size.

My preamble is as below.  I don’t believe this gives me the trim size needed.  However, I’m not sure how to correct it.  Is there an easy way to achieve the necessary trim size for my manuscript?

All best wishes,
Toke
