General ⇒ The length of a line

[tarektarek]

Hi,
I want to ask about how to set a length of a line in a document. Is it using \textwidth 6.5 in? I tried to use this command, but if I reduce the margins on both the left and right sides, I have the same number of pages as before.
I tried to use another command \linewidth 6.5in, and whenever I reduce the margins from both right and left, I can control the number of pages. I am but I think the latter command is not effecting my document. Please let me know what is the case.

Thanks

Hi,

you can use the geometry package to change the page layout of your document; please refer to the User's manual of the package for further details.
