# reverting between marginnote margins and 'normal' margins

How can I revert to normal margins while using marginnote s? In other words, in some pages of my document where I won't use marginnotes, I want the margins to be normal, as though I'm not using marginnotes.

The margin should -- in my opinion -- not be affected by the margin note. Can you show an example where the margins change after inserting a note? –  Uwe Ziegenhagen Sep 24 '12 at 5:23
@UweZiegenhagen : I think OP wants to have two different options for margins (and textblock width), depending on whether the particular page has marginal notes, or not. (Humble opinion: I don't think the result will be very pretty) –  Brent.Longborough Sep 24 '12 at 10:49
Yes Brent, that's what I need. I'm writing a math manual and i'm using lots of marginnotes for diagrams, tips, etc. But when I get to the exercise pages, there's this huge margin that I wish to make narrower. –  jorge aldana Sep 25 '12 at 23:20
\documentclass[twoside]{book} \usepackage[centering,marginparwidth=1.5in,paperheight=10cm]{geometry} \usepackage{marginnote} \usepackage{lipsum} \usepackage{etoolbox} \evensidemargin 1.5in \oddsidemargin 1.5in \setlength{\textwidth}{5.5in} \begin{document} \lipsum[1]\marginnote{test test test test test test test} \lipsum[1-2]\marginnote{test test test test test} %%%%%%%%%% here I get the same wide margin that I had to use for marginnote, %%%%%%%%%% but I want to make it narrower. \lipsum[1-2] \end{document} –  jorge aldana Sep 25 '12 at 23:21
oops I guess I dont know how to add the file.... –  jorge aldana Sep 25 '12 at 23:22

If however you want manually break the pages with \clearpage or similar commands then you know that the page break does not happen mid-paragraph so it is possible to change the width.
Easiest is probably to use the geometry package which allows multiple page sizes to be set up.
