I'm trying to modify a custom thesis-setting class to my needs. It contains commands for setting odd, even and top margins, but I need a particular size (25mm) of the bottom margin as well. I did expect it to be the most elementary feature of LaTeX, but commands such as \bottom or \bmargin lead to crashes of my document. Research on the internet showed, that the bottom margin is not even there on the command-explaining diagram (example: https://www.sharelatex.com/learn/Page_size_and_margins).

So my question is: How do I set a fixed bottom margin size within a class?

    Welcome to LaTeX! Welcome to TeX.SX! Please help us help you and add a minimal working example (MWE) that illustrates your problem. Reproducing the problem and finding out what the issue is will be much easier when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Moriambar Jun 14 '17 at 20:14

    Also, have you tried the geometry package? – Moriambar Jun 14 '17 at 20:14

    In addition to the MWE already requested, could you provide a link or the source of the custom thesis-setting class? – sk8forether Jun 14 '17 at 20:20
  • In any case, the bottom and right margins are just whatever is left of \paperheight and \paperwidth after everything else is specified. – John Kormylo Jun 15 '17 at 21:43
