Text Formatting ⇒ Margins

[waterinus]

Dear friends,
I'm pretty new to Latex and use a template to create my dissertation.
In terms of the margins, the school requires the left and right margins throughout the dissertation should be the same and at least one inch wide each.
However, this template seems not work. I try to find a solution online, it seems it has something to do with \setlength, but I can't figure it out.
Please have a look of the tex and help me if you can!
Thank you so much,
Jianzhou

You can use package geometry to adjust the margins.

Your preamble (at least the part visible to us) is quite wild. A good resource for learners is LaTeX for complete novices.
