# Different layout for exercise, header, etc

1. I want to set different layouts in a book, say the bodywidth (4in) + maginalwidth (2in) and 'exercise part' (6in) at the end of each section such as a typical calculus book. I am using \minipage[h]{6in} for the 'exercise part' right now, which is not good when a part of 'exercise' needs to be carried over to the next page.

2. I want the header (and footer) width to be 6in, even the bodywidth is 4in. Is anyway to do that??

You are missing the 'exercises' tag –  leo Oct 23 '11 at 4:17

You can use the package geometry with the command \newgeometry. For more details see the documentation.
The OP mentions minipages and carrying over text parts to the next page, so it seems he/she wants to change the "margins" for parts of a page. For this, the geometry package is not appropriate. –  lockstep Jan 27 '12 at 20:58
To change the "margins" (better: the indentation) for text blocks in the middle of a page, use the changepage package, the fullwidth package or the addmargin environment of the KOMA-Script classes resp. the scrextend package which is included in KOMA-Script.
